急求解决方案：HTTP/1.1 400 Bad Request
我写了一个http请求的程序，从网上下载一个m3u8的文件。但是不知道为啥总是返回HTTP/1.1 400 Bad Request，求高人指教！！！
返回数据：

程序代码：
static int main(){
SOCKET sSocket = INVALID_SOCKET;
SOCKADDR_IN stSvrAddrIn = {0}; /* 服务器端地址 */
char sndBuf[1024] = {0};
char rcvBuf[1024*200] = {0};
char *pRcv = rcvBuf;
int num = 0;
int nRet = SOCKET_ERROR;
WSADATA wsaData;
int tmplen = 348;
FILE*fp = fopen("D:\\vs2005\\httpRequest\\debug\\http.dat", "wb");
if( fp == NULL )
return -1;
/* HTTP 消息构造开始，这是程序的关键之处 */
sprintf(sndBuf, "GET /m3u8/assign/12345678_20100722_174735_ShenZhenTV_256000.m3u8 HTTP/1.1\r\n");
strcat(sndBuf, "Host: http://live.tvmining.com\n\r\n");
#ifdef WIN32

return -1;
}
}
#endif

/* 连接 */

fwrite(rcvBuf, 1, num, fp);

[解决办法]
貌似你的REQUEST没构造好。。。
[解决办法]
1，host 这里去掉 http://
