㈡ C语言要团购类短信接口，求回答！石家庄的！

C语言可以直接调用webservice接口 当然http也行

团购中验证码和团购券的短信要求很高

速达移动还行，稳定 速度快 主要是服务有保障 其实他们技术人员会帮你实施

还有实例

㈢ C语言Socket服务器怎么给客户端发消息

你的文件中的问题
// 会阻塞进程，直到有客户端连接上来为止
// 既然是直到有客户端连接上，那么就要弄明白哪个是与客户端连接的套接字
// sockClient就是与客户端连接的套接字
sockClient = accept(sockServer, (SOCKADDR*)&addrClient, &len);
//接收并打印客户端数据
recv(sockClient, recvBuf, 100, 0);
printf("%s\n", recvBuf);
// 所以此处，应该把sockServer改为sockClient
send(/*sockServer*/sockClient, sendBuf, 100, 0);

PS：服务器客户端通信，是要保持服务器与客户端的连接。
而不能这样立即关闭，如果设置不对，立即关闭，缓冲区的数据是会丢失的。那客户端也就不会再收到数据了。
你可以加Sleep(10000);来测是通信过程
//关闭socket
closesocket(sockClient);
