求救关于Http post的实现,该如何处理

求救关于Http post的实现
怎样实现一个在第2版和第三版上可用的Http post架构，我现在的想法是要实现一个请求WebService服务的功能，将XML数据直接POST到服务器，，请提供援助。。

楼主你好：
1、你有《Series 60应用程序开发》这本书么？
有的话，在书的第十章（Post具体是在375页）又讲这个的；
2、有一个HTTP客户端的示例代码：
http://www.forum.nokia.com/info/sw.nokia.com/id/6ae1a078-1545-4c2c-b98f-68366474aa6d/S60_Platform_HTTP_Client_API_Example_v2_1_en.zip
你可以参考一下；

不好意思的说，我就用过Get，Post我没有用过，希望上面的东西能对你有用。
