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

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});
});

param: Route.continue.overrides

  • overrides <[Object]>
    • url <[string]> If set changes the request URL. New URL must have same protocol as original one.
    • method <[string]> If set changes the request method (e.g. GET or POST)
    • postData <[string]|[Buffer]> If set changes the post data of request
    • headers <[Object]<[string], [string]>> If set changes the request HTTP headers. Header values will be converted to a string.

Optional request overrides, can override following properties:

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!'
  });
});

An example of serving static file:

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

param: Route.fulfill.response

  • response <[Object]>
    • status <[int]> Response status code, defaults to 200.
    • headers <[Object]<[string], [string]>> Optional response headers. Header values will be converted to a string.
    • contentType <[string]> If set, equals to setting Content-Type response header.
    • body <[string]|[Buffer]> Optional response body.
    • path <[path]> Optional 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.

Response that will fulfill this route's request.

method: Route.request

  • returns: <[Request]>

A request to be routed.
