Method Detail

disable

public static Command<java.lang.Void> disable()

Disables the fetch domain.

enable

public static Command<java.lang.Void> enable(java.util.Optional<java.util.List<RequestPattern>> patterns,
                                             java.util.Optional<java.lang.Boolean> handleAuthRequests)

Enables issuing of requestPaused events. A request will be paused until client calls one of failRequest, fulfillRequest or continueRequest/continueWithAuth.

failRequest

public static Command<java.lang.Void> failRequest(RequestId requestId,
                                                  ErrorReason errorReason)

Causes the request to fail with specified reason.

fulfillRequest

public static Command<java.lang.Void> fulfillRequest(RequestId requestId,
                                                     java.lang.Integer responseCode,
                                                     java.util.Optional<java.util.List<HeaderEntry>> responseHeaders,
                                                     java.util.Optional<java.lang.String> binaryResponseHeaders,
                                                     java.util.Optional<java.lang.String> body,
                                                     java.util.Optional<java.lang.String> responsePhrase)

Provides response to the request.

continueRequest

public static Command<java.lang.Void> continueRequest(RequestId requestId,
                                                      java.util.Optional<java.lang.String> url,
                                                      java.util.Optional<java.lang.String> method,
                                                      java.util.Optional<java.lang.String> postData,
                                                      java.util.Optional<java.util.List<HeaderEntry>> headers)

Continues the request, optionally modifying some of its parameters.

continueWithAuth

public static Command<java.lang.Void> continueWithAuth(RequestId requestId,
                                                       AuthChallengeResponse authChallengeResponse)

Continues a request supplying authChallengeResponse following authRequired event.

getResponseBody

public static Command<Fetch.GetResponseBodyResponse> 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()

authRequired

public static Event<AuthRequired> authRequired()
