GWT RPC 响应标头

发布于 2024-10-01 00:04:38 字数 820 浏览 5 评论 0原文

有没有办法读取 GWT 客户端在 RPC 响应上收到的标头信息？

Response header
Server                 Apache-Coyote/1.1
Set-Cookie             JSESSIONID=3379B1E57BEB2FE227EDC1F57BF550ED; Path=/GWT
Content-Encoding       gzip
Content-Disposition    attachment
Content-Type           application/json;charset=utf-8
Content-Length         209

我特别感兴趣的是确定客户端何时收到其标头上的 Set-Cookie 属性。

在 GWT 上有什么办法可以做到这一点吗？

我发现在

com.google.gwt.user.client.rpc.impl.RequestCallbackAdapter<T>

参数 Response 上存在的方法

public void onResponseReceived(Request request, Response response) { ... }

似乎有我需要的信息。这是，是否有某种方法可以在不“破坏”GWT 编译器代码的情况下实现这一点？

谢谢

Is there any way to read the header information received by GWT client, on the RPC response?

Response header
Server                 Apache-Coyote/1.1
Set-Cookie             JSESSIONID=3379B1E57BEB2FE227EDC1F57BF550ED; Path=/GWT
Content-Encoding       gzip
Content-Disposition    attachment
Content-Type           application/json;charset=utf-8
Content-Length         209
Date                   Fri, 05 Nov 2010 13:07:31 GMT

I'm particularly interest in identifying when client receives the Set-Cookie attribute on its header.

Is there any way to do that on GWT?

I found that on

com.google.gwt.user.client.rpc.impl.RequestCallbackAdapter<T>

exist the method

public void onResponseReceived(Request request, Response response) { ... }

On the parameter Response seems to have the information I need. The this is, exist some way to get that without "racking" the GWT compiler code?

thanks

您可以尝试重写 RpcRequestBuilder.doSetCallback 方法并强制您的服务使用它：

MyServiceAsync service = GWT.create(MyService.clas);
((ServiceDefTarget) service).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) {
                String headerValue = response.getHeader("my-header");
                // do sth...
                callback.onResponseReceived(request, response);
            }

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

You may try to override the RpcRequestBuilder.doSetCallback method and force your service to use it:

MyServiceAsync service = GWT.create(MyService.clas);
((ServiceDefTarget) service).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) {
                String headerValue = response.getHeader("my-header");
                // do sth...
                callback.onResponseReceived(request, response);
            }

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