|
|
- Stealthy Playwright with the stealth mode I wrote for it. It's still a work in progress but it bypasses many online tests like bot.sannysoft.com
|
|
Some of the things stealth mode does include:
|
|
1) Patches the CDP runtime fingerprint.
|
|
2) Mimics some of the real browsers' properties by injecting several JS files and using custom options.
|
|
3) Using custom flags on launch to hide Playwright even more and make it faster.
|
|
4) Generates real browser's headers of the same type and same user OS then append it to the request.
|
|
- Real browsers by passing the `real_chrome` argument or the CDP URL of your browser to be controlled by the Fetcher and most of the options can be enabled on it.
|
|
- NSTBrowser's docker browserless option by passing the CDP URL and enabling `nstbrowser_mode` option.

"""Opens up a browser and do your request based on your chosen options below.

|
|
:param url: Target url.
|
|
:param headless: Run the browser in headless/hidden (default), or headful/visible mode.
|
|
:param disable_resources: Drop requests of unnecessary resources for speed boost. It depends but it made requests ~25% faster in my tests for some websites.
|
|
Requests dropped are of type `font`, `image`, `media`, `beacon`, `object`, `imageset`, `texttrack`, `websocket`, `csp_report`, and `stylesheet`.
|
|
This can help save your proxy usage but be careful with this option as it makes some websites never finish loading.
|
|
:param useragent: Pass a useragent string to be used. Otherwise the fetcher will generate a real Useragent of the same browser and use it.
|
|
:param network_idle: Wait for the page until there are no network connections for at least 500 ms.
|
|
:param timeout: The timeout in milliseconds that is used in all operations and waits through the page. The default is 30000
|
|
:param locale: Set the locale for the browser if wanted. The default value is `en-US`.
|
|
:param page_action: Added for automation. A function that takes the `page` object, does the automation you need, then returns `page` again.
|
|
:param wait_selector: Wait for a specific css selector to be in a specific state.
|
|
:param wait_selector_state: The state to wait for the selector given with `wait_selector`. Default state is `attached`.
|
|
:param stealth: Enables stealth mode, check the documentation to see what stealth mode does currently.
|
|
:param real_chrome: If you have chrome browser installed on your device, enable this and the Fetcher will launch an instance of your browser and use it.
|
|
:param hide_canvas: Add random noise to canvas operations to prevent fingerprinting.
|
|
:param disable_webgl: Disables WebGL and WebGL 2.0 support entirely.
|
|
:param google_search: Enabled by default, Scrapling will set the referer header to be as if this request came from a Google search for this website's domain name.
|
|
:param extra_headers: A dictionary of extra headers to add to the request. _The referer set by the `google_search` argument takes priority over the referer set here if used together._
|
|
:param proxy: The proxy to be used with requests, it can be a string or a dictionary with the keys 'server', 'username', and 'password' only.
|
|
:param cdp_url: Instead of launching a new browser instance, connect to this CDP URL to control real browsers/NSTBrowser through CDP.
|
|
:param nstbrowser_mode: Enables NSTBrowser mode, it have to be used with `cdp_url` argument or it will get completely ignored.
|
|
:param nstbrowser_config: The config you want to send with requests to the NSTBrowser. If left empty, Scrapling defaults to an optimized NSTBrowser's docker browserless config.
