如何使用 HttpClient 发送 GWT-RPC 请求？
我正在使用 Apache HTTPClient API 发送 HTTPRequest，到目前为止它可以处理标准请求。现在我想发送 GWT-RPC 请求并显示响应，但我总是从 GWT-RPC 服务器收到以下错误：
//EX[2,1,"com.google.gwt.user.client.rpc.IncompatibleRemoteServiceException/3936916533","This application is out of date, please click the refresh button on your browser. ( Malformed or old RPC message received - expecting version 5 )"],0,5]
实际上，我必须随请求发送以下数据：
5|0|5|http://172.16.103.244:38081/kunagi/scrum.ScrumGwtApplication/|6E611C647A0C98D5A31A2506E16D81D6|scrum.client.ScrumService|startConversation|I|1|2|3|4|1|5|-1|
但我不知道如何。
当我从 FireBug 检索请求代码时，我在帖子区域中找到了上述数据作为来源。
I am using the Apache HTTPClient API to send HTTPRequests, and so far it's worked with standard requests. Now I want to send a GWT-RPC request and show the response, but I always receive the following error from the GWT-RPC server:
//EX[2,1,"com.google.gwt.user.client.rpc.IncompatibleRemoteServiceException/3936916533","This application is out of date, please click the refresh button on your browser. ( Malformed or old RPC message received - expecting version 5 )"],0,5]
Actually, I have to send the following data with the request:
5|0|5|http://172.16.103.244:38081/kunagi/scrum.ScrumGwtApplication/|6E611C647A0C98D5A31A2506E16D81D6|scrum.client.ScrumService|startConversation|I|1|2|3|4|1|5|-1|
but I don't know how.
When I retrieve the request code from FireBug, I find the above data as a source in the post area.

查看 gwt-syncproxy 项目。它完全符合您的要求，从 Java 代码中伪造 RCP 调用。如果您不想让您的项目依赖于 gwt-syncproxy，您可以查看了解它的实现并了解如何创建有效的请求。
Take a look at the gwt-syncproxy project. It does exactly what you are looking for, faking RCP calls from Java code. If you don't want to rely your project on gwt-syncproxy, you could look at it's implementation and find out how the create valid requests.
