HTTP POST在c中未返回正确的响应

我用C编写了一个http客户端，并在我的服务器上创建了一个post方法，该方法正在运行一个php脚本，该脚本将接收客户端参数并向客户端发回一些响应。但是，成功套接字连接后，服务器将不返回任何内容。我的代码中缺少什么？

这是我的基于off-winsock2 的c客户端

    int main(int argc , char *argv[])
    {
        WSADATA wsa;
        SOCKET s;
        struct sockaddr_in server;
        char *message , server_reply[2000];
        int recv_size;
        printf("'nInitialising Winsock...");
        if (WSAStartup(MAKEWORD(2,2),&wsa) != 0)
        {
            printf("Failed. Error Code : %d",WSAGetLastError());
            return 1;
        }
        printf("Initialised.'n");
        //Create a socket
        if((s = socket(AF_INET , SOCK_STREAM , 0 )) == INVALID_SOCKET)
        {
            printf("Could not create socket : %d" , WSAGetLastError());
        }
        printf("Socket created.'n");

    //    server.sin_addr.s_addr = inet_addr("196.46.123.151");
        server.sin_addr.s_addr = inet_addr("66.96.147.96");
        server.sin_family = AF_INET;
        server.sin_port = htons( 80 );
        //Connect to remote server
        if (connect(s , (struct sockaddr *)&server , sizeof(server)) < 0)
        {
            puts("connect error");
            return 1;
        }
        puts("Connected");

        //----------------------------------------------------------HTTP HEADER PLUS MESSAGE--------------------------------------//
        message = "POST /echo.php HTTP/1.0'r'n Host: www.vocha.co.tz'r'n Content-type: application/x-www-form-urlencoded'r'n Content-Length: 16'r'n'r'n name=iAmWorking!";
        if( send(s , message , strlen(message) , 0) < 0)
        {
            puts("Send failed");
            return 1;
        }
        puts("Data Send'n");
        //Receive a reply from the server
        if((recv_size = recv(s , server_reply , 2000 , 0)) == SOCKET_ERROR)
        {
            puts("recv failed");
        }
        puts("Reply received'n");
        //Add a NULL terminating character to make it a proper string before printing
        server_reply[recv_size] = ''0';
        //print the Server reply
        puts(server_reply);
        //show receive success message
        puts("Data received successfully!");
        //We are done receiving data! close the socket
        closesocket(s);
        WSACleanup();
        return 0;
    }

这是我的服务器端php脚本

    <?php
    // get name from post parameter and store it in variable $name
    $name=$_POST['name']; 
    //echo back a greeting with the user's name
    //this is what will appear in client's HTTP response
    echo 'Hi ' . $name;
    ?>

这是服务器响应和调试消息的一部分。
