Creates a new instance of the chrome driver.
|
|
|
|
Starts the service and then creates new instance of chrome driver.
|
|
|
|
Parameters
|
|
----------
|
|
|
|
options: ChromeOptions, optional, default: None - automatic useful defaults
|
|
this takes an instance of ChromeOptions, mainly to customize browser behavior.
|
|
anything other dan the default, for example extensions or startup options
|
|
are not supported in case of failure, and can probably lowers your undetectability.
|
|
|
|
|
|
user_data_dir: str , optional, default: None (creates temp profile)
|
|
if user_data_dir is a path to a valid chrome profile directory, use it,
|
|
and turn off automatic removal mechanism at exit.
|
|
|
|
driver_executable_path: str, optional, default: None(=downloads and patches new binary)
|
|
|
|
browser_executable_path: str, optional, default: None - use find_chrome_executable
|
|
Path to the browser executable.
|
|
If not specified, make sure the executable's folder is in $PATH
|
|
|
|
port: int, optional, default: 0
|
|
port to be used by the chromedriver executable, this is NOT the debugger port.
|
|
leave it at 0 unless you know what you are doing.
|
|
the default value of 0 automatically picks an available port.
|
|
|
|
enable_cdp_events: bool, default: False
|
|
:: currently for chrome only
|
|
this enables the handling of wire messages
|
|
when enabled, you can subscribe to CDP events by using:
|
|
|
|
driver.add_cdp_listener("Network.dataReceived", yourcallback)
|
|
# yourcallback is an callable which accepts exactly 1 dict as parameter
|
|
|
|
|
|
service_args: list of str, optional, default: None
|
|
arguments to pass to the driver service
|
|
|
|
desired_capabilities: dict, optional, default: None - auto from config
|
|
Dictionary object with non-browser specific capabilities only, such as "item" or "loggingPref".
|
|
|
|
advanced_elements: bool, optional, default: False
|
|
makes it easier to recognize elements like you know them from html/browser inspection, especially when working
|
|
in an interactive environment
|
|
|
|
default webelement repr:
|
|
<selenium.webdriver.remote.webelement.WebElement (session="85ff0f671512fa535630e71ee951b1f2", element="6357cb55-92c3-4c0f-9416-b174f9c1b8c4")>
|
|
|
|
advanced webelement repr
|
|
<WebElement(<a class="mobile-show-inline-block mc-update-infos init-ok" href="#" id="main-cat-switcher-mobile">)>
|
|
|
|
note: when retrieving large amounts of elements ( example: find_elements_by_tag("*") ) and print them, it does take a little more time.
|
|
|
|
|
|
service_log_path: str, optional, default: None
|
|
path to log information from the driver.
|
|
|
|
keep_alive: bool, optional, default: True
|
|
Whether to configure ChromeRemoteConnection to use HTTP keep-alive.
|
|
|
|
log_level: int, optional, default: adapts to python global log level
|
|
|
|
headless: bool, optional, default: False
|
|
can also be specified in the options instance.
|
|
Specify whether you want to use the browser in headless mode.
|
|
warning: this lowers undetectability and not fully supported.
|
|
|
|
version_main: int, optional, default: None (=auto)
|
|
if you, for god knows whatever reason, use
|
|
an older version of Chrome. You can specify it's full rounded version number
|
|
here. Example: 87 for all versions of 87
|
|
|
|
patcher_force_close: bool, optional, default: False
|
|
instructs the patcher to do whatever it can to access the chromedriver binary
|
|
if the file is locked, it will force shutdown all instances.
|
|
setting it is not recommended, unless you know the implications and think
|
|
you might need it.
|
|
|
|
suppress_welcome: bool, optional , default: True
|
|
a "welcome" alert might show up on *nix-like systems asking whether you want to set
|
|
chrome as your default browser, and if you want to send even more data to google.
|
|
now, in case you are nag-fetishist, or a diagnostics data feeder to google, you can set this to False.
|
|
Note: if you don't handle the nag screen in time, the browser loses it's connection and throws an Exception.
|
|
|
|
use_subprocess: bool, optional , default: True,
|
|
|
|
False (the default) makes sure Chrome will get it's own process (so no subprocess of chromedriver.exe or python
|
|
This fixes a LOT of issues, like multithreaded run, but mst importantly. shutting corectly after
|
|
program exits or using .quit()
|
|
you should be knowing what you're doing, and know how python works.
|
|
|
|
unfortunately, there is always an edge case in which one would like to write an single script with the only contents being:
|
|
--start script--
|
|
import undetected_chromedriver as uc
|
|
d = uc.Chrome()
|
|
d.get('https://somesite/')
|
|
---end script --
|
|
|
|
and will be greeted with an error, since the program exists before chrome has a change to launch.
|
|
in that case you can set this to `True`. The browser will start via subprocess, and will keep running most of times.
|
|
! setting it to True comes with NO support when being detected. !
|
|
|
|
no_sandbox: bool, optional, default=True
|
|
uses the --no-sandbox option, and additionally does suppress the "unsecure option" status bar
|
|
this option has a default of True since many people seem to run this as root (....) , and chrome does not start
|
|
when running as root without using --no-sandbox flag.
|
|
|
|
user_multi_procs:
|
|
set to true when you are using multithreads/multiprocessing
|
|
ensures not all processes are trying to modify a binary which is in use by another.
|
|
for this to work. YOU MUST HAVE AT LEAST 1 UNDETECTED_CHROMEDRIVER BINARY IN YOUR ROAMING DATA FOLDER.
|
|
this requirement can be easily satisfied, by just running this program "normal" and close/kill it.
