BrowserContext | Playwright Python

BrowserContexts provide a way to operate multiple independent browser sessions.

If a page opens another page, e.g. with a window.open call, the popup will belong to the parent page's browser context.

Playwright allows creating isolated non-persistent browser contexts with browser.new_context() method. Non-persistent browser contexts don't write any browsing data to disk.

• Sync
• Async

context = browser.new_context()

page = context.new_page()
page.goto("https://example.com")

context.close()

context = await browser.new_context()

page = await context.new_page()
await page.goto("https://example.com")

await context.close()

Adds cookies into this browser context. All pages within this context will have these cookies installed. Cookies can be obtained via browser_context.cookies().

Usage

• Sync
• Async

browser_context.add_cookies([cookie_object1, cookie_object2])

await browser_context.add_cookies([cookie_object1, cookie_object2])

Arguments

• cookies List[Dict]#

  • name str

  • value str

  • url str (optional)

    Either url or domain / path are required. Optional.

  • domain str (optional)

    For the cookie to apply to all subdomains as well, prefix domain with a dot, like this: ".example.com". Either url or domain / path are required. Optional.

  • path str (optional)

    Either url or domain / path are required Optional.

  • expires float (optional)

    Unix time in seconds. Optional.

  • httpOnly bool (optional)

    Optional.

  • secure bool (optional)

    Optional.

  • sameSite "Strict" | "Lax" | "None" (optional)

    Optional.

  • partitionKey str (optional)

    For partitioned third-party cookies (aka CHIPS), the partition key. Optional.

Returns

• NoneType#

Adds a script which would be evaluated in one of the following scenarios:

• Whenever a page is created in the browser context or is navigated.
• Whenever a child frame is attached or navigated in any page in the browser context. In this case, the script is evaluated in the context of the newly attached frame.

The script is evaluated after the document was created but before any of its scripts were run. This is useful to amend the JavaScript environment, e.g. to seed Math.random.

Usage

An example of overriding Math.random before the page loads:

asyncio.run(main())

Arguments

• name str#

  Name of the function on the window object.

• callback Callable#

  Callback function that will be called in the Playwright's context.

Returns

• NoneType#

Grants specified permissions to the browser context. Only grants corresponding permissions to the given origin if specified.

Usage

browser_context.grant_permissions(permissions)
browser_context.grant_permissions(permissions, **kwargs)

Arguments

• permissions List[str]#

  A list of permissions to grant.

  danger

  Supported permissions differ between browsers, and even between different versions of the same browser. Any permission may stop working after an update.

  Here are some permissions that may be supported by some browsers:

  • 'accelerometer'
  • 'ambient-light-sensor'
  • 'background-sync'
  • 'camera'
  • 'clipboard-read'
  • 'clipboard-write'
  • 'geolocation'
  • 'gyroscope'
  • 'magnetometer'
  • 'microphone'
  • 'midi-sysex' (system-exclusive midi)
  • 'midi'
  • 'notifications'
  • 'payment-handler'
  • 'storage-access'
  • 'local-fonts'

• origin str (optional)#

  The origin to grant permissions to, e.g. "https://example.com".

Returns

• NoneType#

note

CDP sessions are only supported on Chromium-based browsers.

Returns the newly created session.

Usage

browser_context.new_cdp_session(page)

Arguments

• page Page | Frame#

  Target to create new session for. For backwards-compatibility, this parameter is named page, but it can be a Page or Frame type.

Returns

• CDPSession#

Creates a new page in the browser context.

Usage

browser_context.new_page()

Returns

• Page#

Routing provides the capability to modify network requests that are made by any page in the browser context. Once route is enabled, every request matching the url pattern will stall unless it's continued, fulfilled or aborted.

note

browser_context.route() will not intercept requests intercepted by Service Worker. See this issue. We recommend disabling Service Workers when using request interception by setting service_workers to 'block'.

Usage

An example of a naive handler that aborts all image requests:

• Sync
• Async

context = browser.new_context()
page = context.new_page()
context.route("**/*.{png,jpg,jpeg}", lambda route: route.abort())
page.goto("https://example.com")
browser.close()

context = await browser.new_context()
page = await context.new_page()
await context.route("**/*.{png,jpg,jpeg}", lambda route: route.abort())
await page.goto("https://example.com")
await browser.close()

or the same snippet using a regex pattern instead:

• Sync
• Async

context = browser.new_context()
page = context.new_page()
context.route(re.compile(r"(\.png$)|(\.jpg$)"), lambda route: route.abort())
page = await context.new_page()
page = context.new_page()
page.goto("https://example.com")
browser.close()

context = await browser.new_context()
page = await context.new_page()
await context.route(re.compile(r"(\.png$)|(\.jpg$)"), lambda route: route.abort())
page = await context.new_page()
await page.goto("https://example.com")
await browser.close()

It is possible to examine the request to decide the route action. For example, mocking all requests that contain some post data, and leaving all other requests as is:

• Sync
• Async

def handle_route(route: Route):
  if ("my-string" in route.request.post_data):
    route.fulfill(body="mocked-data")
  else:
    route.continue_()
context.route("/api/**", handle_route)

async def handle_route(route: Route):
  if ("my-string" in route.request.post_data):
    await route.fulfill(body="mocked-data")
  else:
    await route.continue_()
await context.route("/api/**", handle_route)

Page routes (set up with page.route()) take precedence over browser context routes when request matches both handlers.

To remove a route with its handler you can use browser_context.unroute().

note

Enabling routing disables http cache.

Arguments

• url str | Pattern | Callable[URL]:bool#

  A glob pattern, regex pattern, or predicate that receives a URL to match during routing. If base_url is set in the context options and the provided URL is a string that does not start with *, it is resolved using the new URL() constructor.

• handler Callable[Route, Request]:Promise[Any] | Any#

  handler function to route the request.

• times int (optional) Added in: v1.15#

  How often a route should be used. By default it will be used every time.

Returns

• NoneType#

If specified the network requests that are made in the context will be served from the HAR file. Read more about Replaying from HAR.

Playwright will not serve requests intercepted by Service Worker from the HAR file. See this issue. We recommend disabling Service Workers when using request interception by setting service_workers to 'block'.

Usage

browser_context.route_from_har(har)
browser_context.route_from_har(har, **kwargs)

Arguments

• har Union[str, pathlib.Path]#

  Path to a HAR file with prerecorded network data. If path is a relative path, then it is resolved relative to the current working directory.

• not_found "abort" | "fallback" (optional)#

  • If set to 'abort' any request not found in the HAR file will be aborted.
  • If set to 'fallback' falls through to the next route handler in the handler chain.

  Defaults to abort.

• update bool (optional)#

  If specified, updates the given HAR with the actual network information instead of serving from file. The file is written to disk when browser_context.close() is called.

• update_content "embed" | "attach" (optional) Added in: v1.32#

  Optional setting to control resource content management. If attach is specified, resources are persisted as separate files or entries in the ZIP archive. If embed is specified, content is stored inline the HAR file.

• update_mode "full" | "minimal" (optional) Added in: v1.32#

  When set to minimal, only record information necessary for routing from HAR. This omits sizes, timing, page, cookies, security and other types of HAR information that are not used when replaying from HAR. Defaults to minimal.

• url str | Pattern (optional)#

  A glob pattern, regular expression or predicate to match the request URL. Only requests with URL matching the pattern will be served from the HAR file. If not specified, all requests are served from the HAR file.

Returns

• NoneType#

This method allows to modify websocket connections that are made by any page in the browser context.

Note that only WebSockets created after this method was called will be routed. It is recommended to call this method before creating any pages.

Usage

Below is an example of a simple handler that blocks some websocket messages. See WebSocketRoute for more details and examples.

    return
  ws.send(message)

def handler(ws: WebSocketRoute):
  ws.route_send(lambda message: message_handler(ws, message))
  ws.connect()

context.route_web_socket("/ws", handler)

def message_handler(ws: WebSocketRoute, message: Union[str, bytes]):
  if message == "to-be-blocked":
    return
  ws.send(message)

async def handler(ws: WebSocketRoute):
  ws.route_send(lambda message: message_handler(ws, message))
  await ws.connect()

await context.route_web_socket("/ws", handler)

The extra HTTP headers will be sent with every request initiated by any page in the context. These headers are merged with page-specific extra HTTP headers set with page.set_extra_http_headers(). If page overrides a particular header, page-specific header value will be used instead of the browser context header value.

Usage

browser_context.set_extra_http_headers(headers)

Arguments

• headers Dict[str, str]#

  An object containing additional HTTP headers to be sent with every request. All header values must be strings.

Returns

Usage

Type

• Tracing

note

Only works with Chromium browser's persistent context.

Emitted when new background page is created in the context.

• Sync
• Async

background_page = context.wait_for_event("backgroundpage")

background_page = await context.wait_for_event("backgroundpage")

Usage

browser_context.on("backgroundpage", handler)

Event data

• Page

Emitted when Browser context gets closed. This might happen because of one of the following:

• Browser context is closed.
• Browser application is closed or crashed.
• The browser.close() method was called.

Usage

browser_context.on("close", handler)

Event data

• BrowserContext

Emitted when JavaScript within the page calls one of console API methods, e.g. console.log or console.dir.

The arguments passed into console.log and the page are available on the ConsoleMessage event handler argument.

Usage

• Sync
• Async

def print_args(msg):
    for arg in msg.args:
        print(arg.json_value())

context.on("console", print_args)
page.evaluate("console.log('hello', 5, { foo: 'bar' })")

async def print_args(msg):
    values = []
    for arg in msg.args:
        values.append(await arg.json_value())
    print(values)

context.on("console", print_args)
await page.evaluate("console.log('hello', 5, { foo: 'bar' })")

Event data

• ConsoleMessage

Emitted when a JavaScript dialog appears, such as alert, prompt, confirm or beforeunload. Listener must either dialog.accept() or dialog.dismiss() the dialog - otherwise the page will freeze waiting for the dialog, and actions like click will never finish.

Usage

context.on("dialog", lambda dialog: dialog.accept())

Event data

• Dialog

The event is emitted when a new Page is created in the BrowserContext. The page may still be loading. The event will also fire for popup pages. See also page.on("popup") to receive events about popups relevant to a specific page.

The earliest moment that page is available is when it has navigated to the initial url. For example, when opening a popup with window.open('http://example.com'), this event will fire when the network request to "http://example.com" is done and its response has started loading in the popup. If you would like to route/listen to this network request, use browser_context.route() and browser_context.on("request") respectively instead of similar methods on the Page.

• Sync
