                                                              java.util.Optional<java.lang.String> method,
                                                              java.util.Optional<java.lang.String> postData,

      • continueWithAuth

        public static Command<java.lang.Void> continueWithAuth​(RequestId requestId,
                                                               AuthChallengeResponse authChallengeResponse)
        Continues a request supplying authChallengeResponse following authRequired event.
      • getResponseBody

        public static Command<ResponseBody> getResponseBody​(RequestId requestId)
        Causes the body of the response to be received from the server and returned as a single string. May only be issued for a request that is paused in the Response stage and is mutually exclusive with takeResponseBodyForInterceptionAsStream. Calling other methods that affect the request or disabling fetch domain before body is received results in an undefined behavior.
      • takeResponseBodyAsStream

        public static Command<StreamHandle> takeResponseBodyAsStream​(RequestId requestId)
        Returns a handle to the stream representing the response body. The request must be paused in the HeadersReceived stage. Note that after this command the request can't be continued as is -- client either needs to cancel it or to provide the response body. The stream only supports sequential read, IO.read will fail if the position is specified. This method is mutually exclusive with getResponseBody. Calling other methods that affect the request or disabling fetch domain before body is received results in an undefined behavior.
      • requestPaused

        public static Event<RequestPaused> requestPaused()
        Issued when the domain is enabled and the request URL matches the specified filter. The request is paused until the client responds with one of continueRequest, failRequest or fulfillRequest. The stage of the request can be determined by presence of responseErrorReason and responseStatusCode -- the request is at the response stage if either of these fields is present and in the request stage otherwise.
      • authRequired

        public static Event<AuthRequired> authRequired()
        Issued when the domain is enabled with handleAuthRequests set to true. The request is paused until client responds with continueWithAuth.
