如果失败,我需要重试发送GWT RPC请求(除了HTTP 200之外的任何响应代码).原因很复杂,所以我不会详细说明.到目前为止,我在同一个地方处理所有请求响应,如下所示:

    // We override the RpcRequestBuilder.doSetCallback method and force your service to use it
    // With this we can read the response headers if we need to.
    ((ServiceDefTarget)serviceRPC).setRpcRequestBuilder(new RpcRequestBuilder() {

        @Override
        protected void doSetCallback(RequestBuilder rb, final RequestCallback callback) {
            super.doSetCallback(rb, new RequestCallback() {

                @Override
                public void onResponseReceived(Request request,
                        Response response) {
                    httpResponseOkHandler(callback, request, response);
                }

                @Override
                public void onError(Request request, Throwable exception) {
                    httpResponseErrorHandler(callback, request, exception);
                }
            });
        }
    });

因此,使用httpResponseOkHandler方法,我可以捕获HTTP失败.但是,有没有办法"重新抛出"请求,即重试？我不想存储RPC请求的高级参数,我更愿意使用已经流式传输并准备重新发送的请求内容.

有任何想法吗？
