求救关于Http post的实现

[bestdelpher]

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.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。

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

[miyunhong]

楼上的,,谢谢你的回复,,

我把我的SIS文件传给你试下好吗,,,或者把你的传给我在机上试下,,我现在用下面地址代码生成了SIS,,但在手机上打开时报系统错误,,执行不了,,

代码和你上面的类似,,

我搞了一个星期了,,找了很多资料都不行,,,很多都是手机上不行,,模拟器又可以,,

[e-mail]

[yillchen]

楼上的,不要意思,由于程序是公司的,不方便给你
3rd的SDK是要用SISX安装的,他需要认证,该程序需要用到一些特定的CAPABILITY,如NetworkServices,具体你看看HELP

[bestdelpher]

不是指得你那个，我是指http://www.cppblog.com/Khan/archive/2007/12/19/39024.html上的内容，人家也正好用到了这个类名

[bestdelpher]

我在网上找到了Chttp类（参见http://www.cppblog.com/Khan/archive/2007/12/19/39024.html，注意库文件中有个ecom.h的引用，要改为ecom/ecom.h），经测试，在SDK 3rd fp1上可以运行，但是在SDK 2 FP3上，提示要安装什么网络插件，有大虾弄过没有？

[bestdelpher]

是CHttpEngine类哈

[bestdelpher]

在SDK 3rd fp1上可以运行，但是在SDK 2 FP3上，提示要安装什么网络插件，有大虾弄过没有？

[yillchen]

楼上的,请不要误会,CHttpEngine是我自己包的,你也可以起任何名字

[bestdelpher]

？？？？？？？？？？？？？？？？？？？

嘿嘿, 居然翻到我blog上去了..... 貌似我在3.1和2.3都测试过.... 真机是n95 和 n70 都没有问题. 也没有提示要什么网络插件啊...奇怪了啊
