HTTPRequest.respond

HTTPRequest.respond() method

Fulfills a request with the given response.

Signature:

class HTTPRequest {
  respond(
    response: Partial<ResponseForRequest>,
    priority?: number
  ): Promise<void>;
}

Parameters

Parameter	Type	Description
response	Partial<ResponseForRequest>	the response to fulfill the request with.
priority	number	(Optional) If provided, intercept is resolved using cooperative handling rules. Otherwise, intercept is resolved immediately.

Returns:

Promise<void>

Remarks

To use this, request interception should be enabled with Page.setRequestInterception().

Exception is immediately thrown if the request interception is not enabled.

Example

An example of fulfilling all requests with 404 responses:

await page.setRequestInterception(true);
page.on('request', request => {
  request.respond({
    status: 404,
    contentType: 'text/plain',
    body: 'Not Found!',
  });
});

NOTE: Mocking responses for dataURL requests is not supported. Calling request.respond for a dataURL request is a noop.
