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。。
[解决办法]
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.html
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。

可以参考一下blog:http://blog.csdn.net/Eddy_0825/archive/2007/05/10/1603270.aspx#794800

我只需要Get,,
1、2、3楼的代码我都试了,,
在Nokia 6110 Naviagation 真机上都没成功(都没有出现选择接入点界面,,执行根本反应),,但模拟器上没有问题,yunsi ,,,
开发环境是,,,VS2003 + sdk 3rd fp1;

这是我使用的代码,在N81的手机上测试是可以的,你可以参考参考
我是使用3RD + CARBIDE
我的手机网络选择的CMNET的连网方式,用CMWAP可能不行,你看看你 的手机连网方式是什么
