## v5.0.0 (2021-02-27)
|
||||
|
||||
- chi v5, `github.com/go-chi/chi/v5` introduces the adoption of Go's SIV to adhere to the current state-of-the-tools in Go.
|
||||
- chi v1.5.x did not work out as planned, as the Go tooling is too powerful and chi's adoption is too wide.
|
||||
The most responsible thing to do for everyone's benefit is to just release v5 with SIV, so I present to you all,
|
||||
chi v5 at `github.com/go-chi/chi/v5`. I hope someday the developer experience and ergonomics I've been seeking
|
||||
will still come to fruition in some form, see https://github.com/golang/go/issues/44550

|

|
||||
## v1.5.0 (2020-11-12) - now with go.mod support
|
||||
|
||||
`chi` dates back to 2016 with it's original implementation as one of the first routers to adopt the newly introduced
|
||||
context.Context api to the stdlib -- set out to design a router that is faster, more modular and simpler than anything
|
||||
else out there -- while not introducing any custom handler types or dependencies. Today, `chi` still has zero dependencies,
|
||||
and in many ways is future proofed from changes, given it's minimal nature. Between versions, chi's iterations have been very
|
||||
incremental, with the architecture and api being the same today as it was originally designed in 2016. For this reason it
|
||||
makes chi a pretty easy project to maintain, as well thanks to the many amazing community contributions over the years
|
||||
to who all help make chi better (total of 86 contributors to date -- thanks all!).
|
||||
|
||||
Chi has been an labour of love, art and engineering, with the goals to offer beautiful ergonomics, flexibility, performance
|
||||
and simplicity when building HTTP services with Go. I've strived to keep the router very minimal in surface area / code size,
|
||||
and always improving the code wherever possible -- and as of today the `chi` package is just 1082 lines of code (not counting
|
||||
middlewares, which are all optional). As well, I don't have the exact metrics, but from my analysis and email exchanges from
|
||||
companies and developers, chi is used by thousands of projects around the world -- thank you all as there is no better form of
|
||||
joy for me than to have art I had started be helpful and enjoyed by others. And of course I use chi in all of my own projects too :)
|
||||
|
||||
For me, the asthetics of chi's code and usage are very important. With the introduction of Go's module support
|
||||
(which I'm a big fan of), chi's past versioning scheme choice to v2, v3 and v4 would mean I'd require the import path
|
||||
of "github.com/go-chi/chi/v4", leading to the lengthy discussion at https://github.com/go-chi/chi/issues/462.
|
||||
Haha, to some, you may be scratching your head why I've spent > 1 year stalling to adopt "/vXX" convention in the import
|
||||
path -- which isn't horrible in general -- but for chi, I'm unable to accept it as I strive for perfection in it's API design,
|
||||
aesthetics and simplicity. It just doesn't feel good to me given chi's simple nature -- I do not foresee a "v5" or "v6",
|
||||
and upgrading between versions in the future will also be just incremental.
|
||||
|
||||
I do understand versioning is a part of the API design as well, which is why the solution for a while has been to "do nothing",
|
||||
as Go supports both old and new import paths with/out go.mod. However, now that Go module support has had time to iron out kinks and
|
||||
is adopted everywhere, it's time for chi to get with the times. Luckily, I've discovered a path forward that will make me happy,
|
||||
while also not breaking anyone's app who adopted a prior versioning from tags in v2/v3/v4. I've made an experimental release of
|
||||
v1.5.0 with go.mod silently, and tested it with new and old projects, to ensure the developer experience is preserved, and it's
|
||||
largely unnoticed. Fortunately, Go's toolchain will check the tags of a repo and consider the "latest" tag the one with go.mod.
|
||||
However, you can still request a specific older tag such as v4.1.2, and everything will "just work". But new users can just
|
||||
`go get github.com/go-chi/chi` or `go get github.com/go-chi/chi@latest` and they will get the latest version which contains
|
||||
go.mod support, which is v1.5.0+. `chi` will not change very much over the years, just like it hasn't changed much from 4 years ago.
|
||||
Therefore, we will stay on v1.x from here on, starting from v1.5.0. Any breaking changes will bump a "minor" release and
|
||||
backwards-compatible improvements/fixes will bump a "tiny" release.
|
||||
|
||||
For existing projects who want to upgrade to the latest go.mod version, run: `go get -u github.com/go-chi/chi@v1.5.0`,
|
||||
which will get you on the go.mod version line (as Go's mod cache may still remember v4.x). Brand new systems can run
|
||||
`go get -u github.com/go-chi/chi` or `go get -u github.com/go-chi/chi@latest` to install chi, which will install v1.5.0+
|
||||
built with go.mod support.

|
||||
My apologies to the developers who will disagree with the decisions above, but, hope you'll try it and see it's a very
|
||||
minor request which is backwards compatible and won't break your existing installations.
|
||||
|
||||
Cheers all, happy coding!

||||
- Add new `URLFormat` handler to chi/middleware sub-pkg to make working with url mime
|
||||
suffixes easier, ie. parsing `/articles/1.json` and `/articles/1.xml`. See comments in
|
||||
https://github.com/go-chi/chi/blob/master/middleware/url_format.go for example usage.
|
||||
|
||||
|
||||
## v3.0.0 (2017-06-21)
|
||||
|
||||
- Major update to chi library with many exciting updates, but also some *breaking changes*
|
||||
- URL parameter syntax changed from `/:id` to `/{id}` for even more flexible routing, such as
|
||||
`/articles/{month}-{day}-{year}-{slug}`, `/articles/{id}`, and `/articles/{id}.{ext}` on the
|
||||
same router
|
||||
- Support for regexp for routing patterns, in the form of `/{paramKey:regExp}` for example:
|
||||
`r.Get("/articles/{name:[a-z]+}", h)` and `chi.URLParam(r, "name")`
|
||||
- Add `Method` and `MethodFunc` to `chi.Router` to allow routing definitions such as
|
||||
`r.Method("GET", "/", h)` which provides a cleaner interface for custom handlers like
|
||||
in `_examples/custom-handler`
|
||||
- Deprecating `mux#FileServer` helper function. Instead, we encourage users to create their
|
||||
own using file handler with the stdlib, see `_examples/fileserver` for an example
|
||||
- Add support for LINK/UNLINK http methods via `r.Method()` and `r.MethodFunc()`
|
||||
- Moved the chi project to its own organization, to allow chi-related community packages to
|
||||
be easily discovered and supported, at: https://github.com/go-chi
|
||||
- *NOTE:* please update your import paths to `"github.com/go-chi/chi"`
|
||||
- *NOTE:* chi v2 is still available at https://github.com/go-chi/chi/tree/v2
|
||||
|
||||
|
||||
## v2.1.0 (2017-03-30)
|
||||
|
||||
- Minor improvements and update to the chi core library
|
||||
- Introduced a brand new `chi/render` sub-package to complete the story of building
|
||||
APIs to offer a pattern for managing well-defined request / response payloads. Please
|
||||
check out the updated `_examples/rest` example for how it works.
|
||||
- Added `MethodNotAllowed(h http.HandlerFunc)` to chi.Router interface
|
||||
|
||||
|
||||
## v2.0.0 (2017-01-06)
|
||||
|
||||
- After many months of v2 being in an RC state with many companies and users running it in
|
||||
production, the inclusion of some improvements to the middlewares, we are very pleased to
|
||||
announce v2.0.0 of chi.
|
||||
|
||||
|
||||
## v2.0.0-rc1 (2016-07-26)
|
||||
|
||||
- Huge update! chi v2 is a large refactor targetting Go 1.7+. As of Go 1.7, the popular
|
||||
community `"net/context"` package has been included in the standard library as `"context"` and
|
||||
utilized by `"net/http"` and `http.Request` to managing deadlines, cancelation signals and other
|
||||
request-scoped values. We're very excited about the new context addition and are proud to
|
||||
introduce chi v2, a minimal and powerful routing package for building large HTTP services,
|
||||
with zero external dependencies. Chi focuses on idiomatic design and encourages the use of
|
||||
stdlib HTTP handlers and middlwares.
|
||||
- chi v2 deprecates its `chi.Handler` interface and requires `http.Handler` or `http.HandlerFunc`
|
||||
- chi v2 stores URL routing parameters and patterns in the standard request context: `r.Context()`
|
||||
- chi v2 lower-level routing context is accessible by `chi.RouteContext(r.Context()) *chi.Context`,
|
||||
which provides direct access to URL routing parameters, the routing path and the matching
|
||||
routing patterns.
|
||||
- Users upgrading from chi v1 to v2, need to:
|
||||
1. Update the old chi.Handler signature, `func(ctx context.Context, w http.ResponseWriter, r *http.Request)` to
|
||||
the standard http.Handler: `func(w http.ResponseWriter, r *http.Request)`
|
||||
2. Use `chi.URLParam(r *http.Request, paramKey string) string`
|
||||
or `URLParamFromCtx(ctx context.Context, paramKey string) string` to access a url parameter value
|
||||
|
||||
|
||||
## v1.0.0 (2016-07-01)
|
||||
|
||||
- Released chi v1 stable https://github.com/go-chi/chi/tree/v1.0.0 for Go 1.6 and older.
|
||||
|
||||
|
||||
## v0.9.0 (2016-03-31)
|
||||
|
||||
- Reuse context objects via sync.Pool for zero-allocation routing [#33](https://github.com/go-chi/chi/pull/33)
|
||||
- BREAKING NOTE: due to subtle API changes, previously `chi.URLParams(ctx)["id"]` used to access url parameters
|
||||
has changed to: `chi.URLParam(ctx, "id")`

|
||||
|
||||
`chi` is a lightweight, idiomatic and composable router for building Go HTTP services. It's
|
||||
especially good at helping you write large REST API services that are kept maintainable as your
|
||||
project grows and changes. `chi` is built on the new `context` package introduced in Go 1.7 to
|
||||
handle signaling, cancelation and request-scoped values across a handler chain.
|
||||
|
||||
The focus of the project has been to seek out an elegant and comfortable design for writing
|
||||
REST API servers, written during the development of the Pressly API service that powers our
|
||||
public API service, which in turn powers all of our client-side applications.
|
||||
|
||||
The key considerations of chi's design are: project structure, maintainability, standard http
|
||||
handlers (stdlib-only), developer productivity, and deconstructing a large system into many small
|
||||
parts. The core router `github.com/go-chi/chi` is quite small (less than 1000 LOC), but we've also
|
||||
included some useful/optional subpackages: [middleware](/middleware), [render](https://github.com/go-chi/render)
|
||||
and [docgen](https://github.com/go-chi/docgen). We hope you enjoy it too!
|
||||
|
||||
## Install
|
||||
|
||||
`go get -u github.com/go-chi/chi/v5`
|
||||
|
||||
|
||||
## Features
|
||||
|
||||
* **Lightweight** - cloc'd in ~1000 LOC for the chi router
|
||||
* **Fast** - yes, see [benchmarks](#benchmarks)
|
||||
* **100% compatible with net/http** - use any http or middleware pkg in the ecosystem that is also compatible with `net/http`
|
||||
* **Designed for modular/composable APIs** - middlewares, inline middlewares, route groups and sub-router mounting
|
||||
* **Context control** - built on new `context` package, providing value chaining, cancellations and timeouts
|
||||
* **Robust** - in production at Pressly, CloudFlare, Heroku, 99Designs, and many others (see [discussion](https://github.com/go-chi/chi/issues/91))
|
||||
* **Doc generation** - `docgen` auto-generates routing documentation from your source to JSON or Markdown
|
||||
* **Go.mod support** - as of v5, go.mod support (see [CHANGELOG](https://github.com/go-chi/chi/blob/master/CHANGELOG.md))
|
||||
* **No external dependencies** - plain ol' Go stdlib + net/http
|
||||
|
||||
|
||||
## Examples
|
||||
|
||||
See [_examples/](https://github.com/go-chi/chi/blob/master/_examples/) for a variety of examples.
|
||||
|
||||
|
||||
**As easy as:**
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"net/http"
|
||||
|
||||
"github.com/go-chi/chi/v5"
|
||||
"github.com/go-chi/chi/v5/middleware"
|
||||
)
|
||||
|
||||
func main() {
|
||||
r := chi.NewRouter()
|
||||
r.Use(middleware.Logger)
|
||||
r.Get("/", func(w http.ResponseWriter, r *http.Request) {
|
||||
w.Write([]byte("welcome"))
|
||||
})
|
||||
http.ListenAndServe(":3000", r)
|
||||
}
|
||||
```
|
||||
|
||||
**REST Preview:**
|
||||
|
||||
Here is a little preview of how routing looks like with chi. Also take a look at the generated routing docs
|
||||
in JSON ([routes.json](https://github.com/go-chi/chi/blob/master/_examples/rest/routes.json)) and in
|
||||
Markdown ([routes.md](https://github.com/go-chi/chi/blob/master/_examples/rest/routes.md)).
|
||||
|
||||
I highly recommend reading the source of the [examples](https://github.com/go-chi/chi/blob/master/_examples/) listed
|
||||
above, they will show you all the features of chi and serve as a good form of documentation.
|
||||
|
||||
```go
|
||||
import (
|
||||
//...
|
||||
"context"
|
||||
"github.com/go-chi/chi/v5"
|
||||
"github.com/go-chi/chi/v5/middleware"
|
||||
)
|
||||
|
||||
func main() {
|
||||
r := chi.NewRouter()
|
||||
|
||||
// A good base middleware stack
|
||||
r.Use(middleware.RequestID)
|
||||
r.Use(middleware.RealIP)
|
||||
r.Use(middleware.Logger)
|
||||
r.Use(middleware.Recoverer)
|
||||
|
||||
// Set a timeout value on the request context (ctx), that will signal
|
||||
// through ctx.Done() that the request has timed out and further
|
||||
// processing should be stopped.
|
||||
r.Use(middleware.Timeout(60 * time.Second))
|
||||
|
||||
r.Get("/", func(w http.ResponseWriter, r *http.Request) {
|
||||
w.Write([]byte("hi"))
|
||||
})

||||
|

// RESTy routes for "articles" resource
|

|

## Router interface
|
||||
|
||||
chi's router is based on a kind of [Patricia Radix trie](https://en.wikipedia.org/wiki/Radix_tree).
|
||||
The router is fully compatible with `net/http`.
|
||||
|
||||
Built on top of the tree is the `Router` interface:
|
||||
|
||||
```go
|
||||
// Router consisting of the core routing methods used by chi's Mux,
|
||||
// using only the standard net/http.
|
||||
type Router interface {
|
||||
http.Handler
|
||||
Routes
|
||||
|
||||
// Use appends one or more middlewares onto the Router stack.
|
||||
Use(middlewares ...func(http.Handler) http.Handler)
|
||||
|
||||
// With adds inline middlewares for an endpoint handler.
|
||||
With(middlewares ...func(http.Handler) http.Handler) Router
|
||||
|
||||
// Group adds a new inline-Router along the current routing
|
||||
// path, with a fresh middleware stack for the inline-Router.
|
||||
Group(fn func(r Router)) Router
|
||||
|
||||
// Route mounts a sub-Router along a `pattern`` string.
|
||||
Route(pattern string, fn func(r Router)) Router
|
||||
|
||||
// Mount attaches another http.Handler along ./pattern/*
|
||||
Mount(pattern string, h http.Handler)
|
||||
|
||||
// Handle and HandleFunc adds routes for `pattern` that matches
|
||||
// all HTTP methods.
|
||||
Handle(pattern string, h http.Handler)
|
||||
HandleFunc(pattern string, h http.HandlerFunc)
|
||||
|
||||
// Method and MethodFunc adds routes for `pattern` that matches
|
||||
// the `method` HTTP method.
|
||||
Method(method, pattern string, h http.Handler)
|
||||
MethodFunc(method, pattern string, h http.HandlerFunc)
|
||||
|
||||
// HTTP-method routing along `pattern`
|
||||
Connect(pattern string, h http.HandlerFunc)
|
||||
Delete(pattern string, h http.HandlerFunc)
|
||||
Get(pattern string, h http.HandlerFunc)
|
||||
Head(pattern string, h http.HandlerFunc)
|
||||
Options(pattern string, h http.HandlerFunc)
|
||||
Patch(pattern string, h http.HandlerFunc)
|
||||
Post(pattern string, h http.HandlerFunc)
|
||||
Put(pattern string, h http.HandlerFunc)
|
||||
Trace(pattern string, h http.HandlerFunc)
|
||||
|
||||
// NotFound defines a handler to respond whenever a route could
|
||||
// not be found.
|
||||
NotFound(h http.HandlerFunc)
|
||||
|
||||
// MethodNotAllowed defines a handler to respond whenever a method is
|
||||
// not allowed.
|
||||
MethodNotAllowed(h http.HandlerFunc)
|
||||
}
|
||||
|
||||
// Routes interface adds two methods for router traversal, which is also
|
||||
// used by the github.com/go-chi/docgen package to generate documentation for Routers.
|
||||
type Routes interface {
|
||||
// Routes returns the routing tree in an easily traversable structure.
|
||||
Routes() []Route
|
||||
|
||||
// Middlewares returns the list of middlewares in use by the router.
|
||||
Middlewares() Middlewares
|
||||
|
||||
// Match searches the routing tree for a handler that matches
|
||||
// the method/path - similar to routing a http request, but without
|
||||
// executing the handler thereafter.
|
||||
Match(rctx *Context, method, path string) bool
|
||||
}
|
||||
```
|
||||
|
||||
Each routing method accepts a URL `pattern` and chain of `handlers`. The URL pattern
|
||||
supports named params (ie. `/users/{userID}`) and wildcards (ie. `/admin/*`). URL parameters
|
||||
can be fetched at runtime by calling `chi.URLParam(r, "userID")` for named parameters
|
||||
and `chi.URLParam(r, "*")` for a wildcard parameter.
|
||||
|
||||
|
||||
### Middleware handlers
|
||||
|
||||
chi's middlewares are just stdlib net/http middleware handlers. There is nothing special
|
||||
about them, which means the router and all the tooling is designed to be compatible and
|
||||
friendly with any middleware in the community. This offers much better extensibility and reuse
|
||||
of packages and is at the heart of chi's purpose.
|
||||
|
||||
Here is an example of a standard net/http middleware where we assign a context key `"user"`
|
||||
the value of `"123"`. This middleware sets a hypothetical user identifier on the request
|
||||
context and calls the next handler in the chain.
|
||||
|
||||
```go
|
||||
// HTTP middleware setting a value on the request context
|
||||
func MyMiddleware(next http.Handler) http.Handler {
|
||||
return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
|
||||
// create new context from `r` request context, and assign key `"user"`
|
||||
// to value of `"123"`
|
||||
ctx := context.WithValue(r.Context(), "user", "123")
|
||||
|
||||
// call the next handler in the chain, passing the response writer and
|
||||
// the updated request object with the new context value.
|
||||
//
|
||||
// note: context.Context values are nested, so any previously set
|
||||
// values will be accessible as well, and the new `"user"` key
|
||||
// will be accessible from this point forward.
|
||||
next.ServeHTTP(w, r.WithContext(ctx))
|
||||
})
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
### Request handlers
|
||||
|
||||
chi uses standard net/http request handlers. This little snippet is an example of a http.Handler
|
||||
func that reads a user identifier from the request context - hypothetically, identifying
|
||||
the user sending an authenticated request, validated+set by a previous middleware handler.
|
||||
|
||||
```go
|
||||
// HTTP handler accessing data from the request context.
|
||||
func MyRequestHandler(w http.ResponseWriter, r *http.Request) {
|
||||
// here we read from the request context and fetch out `"user"` key set in
|
||||
// the MyMiddleware example above.
|
||||
user := r.Context().Value("user").(string)
|
||||
|
||||
// respond to the client
|
||||
w.Write([]byte(fmt.Sprintf("hi %s", user)))
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
### URL parameters
|
||||
|
||||
chi's router parses and stores URL parameters right onto the request context. Here is
|
||||
an example of how to access URL params in your net/http handlers. And of course, middlewares
|
||||
are able to access the same information.
|
||||
|
||||
```go
|
||||
// HTTP handler accessing the url routing parameters.
|
||||
func MyRequestHandler(w http.ResponseWriter, r *http.Request) {
|
||||
// fetch the url parameter `"userID"` from the request of a matching
|
||||
// routing pattern. An example routing pattern could be: /users/{userID}
|
||||
userID := chi.URLParam(r, "userID")
|
||||
|
||||
// fetch `"key"` from the request context
|
||||
ctx := r.Context()
|
||||
key := ctx.Value("key").(string)
|
||||
|
||||
// respond to the client
|
||||
w.Write([]byte(fmt.Sprintf("hi %v, %v", userID, key)))
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
## Middlewares
|
||||
|
||||
chi comes equipped with an optional `middleware` package, providing a suite of standard
|
||||
`net/http` middlewares. Please note, any middleware in the ecosystem that is also compatible
|
||||
with `net/http` can be used with chi's mux.
|
||||
|
||||

## context?
|
||||
|
||||
`context` is a tiny pkg that provides simple interface to signal context across call stacks
|
||||
and goroutines. It was originally written by [Sameer Ajmani](https://github.com/Sajmani)
|
||||
and is available in stdlib since go1.7.
|
||||

||||

Comparison with other routers: https://gist.github.com/pkieltyka/123032f12052520aaccab752bd3e78cc
|
||||
|
||||
NOTE: the allocs in the benchmark above are from the calls to http.Request's
|
||||
`WithContext(context.Context)` method that clones the http.Request, sets the `Context()`
|
||||
on the duplicated (alloc'd) request and returns it the new request object. This is just
|
||||
how setting context on a request in Go works.

## Beyond REST
|
||||
|
||||
chi is just a http router that lets you decompose request handling into many smaller layers.
|
||||
Many companies use chi to write REST services for their public APIs. But, REST is just a convention
|
||||
for managing state via HTTP, and there's a lot of other pieces required to write a complete client-server
|
||||
system or network of microservices.
|
||||
|
||||
Looking beyond REST, I also recommend some newer works in the field:
|
||||
* [webrpc](https://github.com/webrpc/webrpc) - Web-focused RPC client+server framework with code-gen
|
||||
* [gRPC](https://github.com/grpc/grpc-go) - Google's RPC framework via protobufs
|
||||
* [graphql](https://github.com/99designs/gqlgen) - Declarative query language
|
||||
* [NATS](https://nats.io) - lightweight pub-sub

// package main

//
|
||||
// import (
|
||||
// "net/http"
|
||||
//
|
||||
// "github.com/go-chi/chi/v5"
|

// "github.com/go-chi/chi/v5/middleware"

//

// func main() {
|
||||
// r := chi.NewRouter()
|
||||
// r.Use(middleware.Logger)
|
||||
// r.Use(middleware.Recoverer)
|
||||
//
|
||||
// r.Get("/", func(w http.ResponseWriter, r *http.Request) {
|
||||
// w.Write([]byte("root."))
|
||||
// })
|
||||
//

||||
// http.ListenAndServe(":3333", r)
|
||||
// }
|
||||
//
|
||||
// See github.com/go-chi/chi/_examples/ for more in-depth examples.
|
||||
//
|
||||
// URL patterns allow for easy matching of path components in HTTP
|
||||
// requests. The matching components can then be accessed using
|
||||
// chi.URLParam(). All patterns must begin with a slash.
|
||||
//
|
||||
// A simple named placeholder {name} matches any sequence of characters
|
||||
// up to the next / or the end of the URL. Trailing slashes on paths must
|
||||
// be handled explicitly.
|
||||
//
|
||||
// A placeholder with a name followed by a colon allows a regular
|
||||
// expression match, for example {number:\\d+}. The regular expression
|
||||
// syntax is Go's normal regexp RE2 syntax, except that regular expressions
|
||||
// including { or } are not supported, and / will never be
|
||||
// matched. An anonymous regexp pattern is allowed, using an empty string
|
||||
// before the colon in the placeholder, such as {:\\d+}
|
||||
//
|
||||
// The special placeholder of asterisk matches the rest of the requested
|
||||
// URL. Any trailing characters in the pattern are ignored. This is the only
|
||||
// placeholder which will match / characters.
|
||||
//
|
||||
// Examples:
|
||||
// "/user/{name}" matches "/user/jsmith" but not "/user/jsmith/info" or "/user/jsmith/"
|
||||
// "/user/{name}/info" matches "/user/jsmith/info"
|
||||
// "/page/*" matches "/page/intro/latest"
|
||||
// "/page/*/index" also matches "/page/intro/latest"
|
||||
// "/date/{yyyy:\\d\\d\\d\\d}/{mm:\\d\\d}/{dd:\\d\\d}" matches "/date/2017/04/01"
