class: Route

Whenever a network route is set up with page.route(url, handler) or browserContext.route(url, handler), the Route object allows to handle the route.

• route.abort([errorCode])
• route.continue([overrides])
• route.fulfill(response)
• route.request()

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.
• returns: <Promise>

Aborts the route’s request.

route.continue([overrides])

• overrides <Object> Optional request overrides, which can be one of the following:
  • method <string> If set changes the request method (e.g. GET or POST)
  • postData <string> 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.
• returns: <Promise>

Continues route’s request with optional overrides.

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

route.fulfill(response)

• response <Object> Response that will fulfill this route’s request.
  • status <number> 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 <string> 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 current working directory.
• returns: <Promise>

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' }));

route.request()

• returns: <Request> A request to be routed.
