请问怎样用socket进行post表单。(不是用MFC)，怎么搞呢？

Question

Send 时，你要发送的数据主要是：
POST http://xxx.xxx.xx/xxx.html /HTTP 1.0
Content-Length: ???xx=xxx&xxx=xxx

Answer 1

static char *g_pszSendLog = "POST /member/logon.asp\r\n"
"Content-Type: application/x-www-form-urlencoded\r\n"
"Content-Length: 99\r\n"
"\r\n" // 空行
"name=ttzzgg_80713&pass=xxxx&type=1\r\n";
不知道是不是正确的呢。返回的是一个200 OK，不过却说我没有输入用户名
和密码

Answer 2

form的数据，格式有多种，这个是由enctype决定的。rfc里面有详细的描述

Answer 3

我用wininet编程时遇到同样问题！字符串被识别是图形数据了！登陆不上去！
