rfc1867,有关http form的详细说明
接收到的数据，注意要判断是否为chunk编码

[beipiao]

其实这种问题的解答，论坛里面搜索一下，有很多的

post数据，boundary随即生成

Content-type: multipart/form-data, boundary=AaB03x

--AaB03x
content-disposition: form-data; name="user"

Wilson Peng
--AaB03x
content-disposition: form-data; name="myfile"
Content-type: multipart/mixed, boundary=BbC04y

--BbC04y
Content-disposition: attachment; filename="myphoto.gif"
Content-type: image/gif
Content-Transfer-Encoding: binary

...myphoto.gif 内容略...
--BbC04y--
--AaB03x--

up！！

[ALong_Yue]

谢谢大家的回复！！！

vcmute(横秋)：可以给一个例子吗？

xuzheng318(forever C++)(忧郁王子)：我需要上传文件，而不是POST一个http请求这么简单。

在服务器端，有一个页面负责接收。请高手多多帮忙！！

[ALong_Yue]

最好使用MFC类实现：（

我的BLOG收录了一篇文章。看上面的链接。。

kugou123(酷狗):编译你在blog提供的代码，出现下列问题：

nafxcwd.lib(thrdcore.obj) : error LNK2001: unresolved external symbol __endthreadex

#include <process.h> 试试

[kyh1234567]

kugou123(酷狗):
正解，我刚刚试过，把#include <process.h>加上后就没问题了
