class: Route

Whenever a network route is set up with [method: Page.route] or [method: BrowserContext.route], the Route object allows to handle the route.

async method: Route.abort

Aborts the route's request.

param: Route.abort.errorCode

• errorCode <[string]>

Optional error code. Defaults to failed, could be one of the following:

• 'aborted' - An operation was aborted (due to user action)
• 'accessdenied' - Permission to access a resource, other than the network, was denied
• 'addressunreachable' - The IP address is unreachable. This usually means that there is no route to the specified host or network.
• 'blockedbyclient' - The client chose to block the request.
• 'blockedbyresponse' - The request failed because the response was delivered along with requirements which are not met ('X-Frame-Options' and 'Content-Security-Policy' ancestor checks, for instance).
• 'connectionaborted' - A connection timed out as a result of not receiving an ACK for data sent.
• 'connectionclosed' - A connection was closed (corresponding to a TCP FIN).
• 'connectionfailed' - A connection attempt failed.
• 'connectionrefused' - A connection attempt was refused.
• 'connectionreset' - A connection was reset (corresponding to a TCP RST).
• 'internetdisconnected' - The Internet connection has been lost.
• 'namenotresolved' - The host name could not be resolved.
• 'timedout' - An operation timed out.
• 'failed' - A generic failure occurred.

async method: Route.continue

• langs:
  • alias-java: resume
  • alias-python: continue_

Continues route's request with optional overrides.

await page.route('**/*', (route, request) => {
  // Override headers
  const headers = {
    ...request.headers(),
    foo: 'bar', // set "foo" header
    origin: undefined, // remove "origin" header
  };
  route.continue({headers});
});

page.route("**/*", route -> {
  // Override headers
  Map<String, String> headers = new HashMap<>(route.request().headers());
  headers.put("foo", "bar"); // set "foo" header
  headers.remove("origin"); // remove "origin" header
  route.resume(new Route.ResumeOptions().setHeaders(headers));
});

async def handle(route, request):
    # override headers
    headers = {
        **request.headers,
        "foo": "bar" # set "foo" header
        "origin": None # remove "origin" header
    }
    await route.continue_(headers=headers)
}
await page.route("**/*", handle)

def handle(route, request):
    # override headers
    headers = {
        **request.headers,
        "foo": "bar" # set "foo" header
        "origin": None # remove "origin" header
    }
    route.continue_(headers=headers)
}
page.route("**/*", handle)

await page.RouteAsync("**/*", route =>
{
    var headers = new Dictionary<string, string>(route.Request.Headers) { { "foo", "bar" } };
    headers.Remove("origin");
    route.ContinueAsync(headers);
});

option: Route.continue.url

• url <[string]>

If set changes the request URL. New URL must have same protocol as original one.

option: Route.continue.method

• method <[string]>

If set changes the request method (e.g. GET or POST)

option: Route.continue.postData

• postData <[string]|[Buffer]>

If set changes the post data of request

option: Route.continue.headers

• headers <[Object]<[string], [string]>>

If set changes the request HTTP headers. Header values will be converted to a string.

async method: Route.fulfill

Fulfills route's request with given response.

An example of fulfilling all requests with 404 responses:

await page.route('**/*', route => {
  route.fulfill({
    status: 404,
    contentType: 'text/plain',
    body: 'Not Found!'
  });
});

page.route("**/*", route -> {
  route.fulfill(new Route.FulfillOptions()
    .setStatus(404)
    .setContentType("text/plain")
    .setBody("Not Found!"));
});

await page.route("**/*", lambda route: route.fulfill(
    status=404,
    content_type="text/plain",
    body="not found!"))

page.route("**/*", lambda route: route.fulfill(
    status=404,
    content_type="text/plain",
    body="not found!"))

await page.RouteAsync("**/*", route => route.FulfillAsync(
    status: 404,
    contentType: "text/plain", 
    body: "Not Found!"));

An example of serving static file:

await page.route('**/xhr_endpoint', route => route.fulfill({ path: 'mock_data.json' }));

page.route("**/xhr_endpoint", route -> route.fulfill(
  new Route.FulfillOptions().setPath(Paths.get("mock_data.json"))));

await page.route("**/xhr_endpoint", lambda route: route.fulfill(path="mock_data.json"))

page.route("**/xhr_endpoint", lambda route: route.fulfill(path="mock_data.json"))

await page.RouteAsync("**/xhr_endpoint", route => route.FulfillAsync(new RouteFulfillOptions { Path = "mock_data.json" }));

option: Route.fulfill.status

• status <[int]>

Response status code, defaults to 200.

option: Route.fulfill.headers

• headers <[Object]<[string], [string]>>

Response headers. Header values will be converted to a string.

option: Route.fulfill.contentType

• contentType <[string]>

If set, equals to setting Content-Type response header.

option: Route.fulfill.body

• langs: js, python

• body <[string]|[Buffer]>

Response body.

option: Route.fulfill.body

• langs: csharp, java

• body <[string]>

Optional response body as text.

option: Route.fulfill.bodyBytes

• langs: csharp, java

• bodyBytes <[Buffer]>

Optional response body as raw bytes.

option: Route.fulfill.path

• path <[path]>

File path to respond with. The content type will be inferred from file extension. If path is a relative path, then it is resolved relative to the current working directory.

option: Route.fulfill.response

• langs: js

• response <[APIResponse]>

[APIResponse] to fulfill route's request with. Individual fields of the response (such as headers) can be overridden using fulfill options.

method: Route.request

• returns: <[Request]>

A request to be routed.
