html - 如何在 Windows 中使用 C 提交表单

问题描述

我正在尝试以 html 形式实现一个简单的 Web 服务器。它必须是 C 语言和 Windows 用户。

    if (WSAStartup(MAKEWORD(2, 2), &wsa) != 0)  // wsa will hold additional info after winsock has been loaded.
    {
        printf("Failed. Error Code : %d", WSAGetLastError());
        exit(EXIT_FAILURE);
    }
    printf("Initialised.\n");



    //Create socket
    socket_desc = SocketCreate();
    if (socket_desc == -1)
    {
        printf("Could not create socket");
        return 1;
    }
    printf("Socket created\n");
    //Bind
    if (BindCreatedSocket(socket_desc) < 0)
    {
        //print the error message
        perror("bind failed.");

        clientLen = sizeof(struct sockaddr_in);
        //accept connection from an incoming client
        sock = accept(socket_desc, (struct sockaddr *)&client, (int *)&clientLen);
        if (sock < 0)
        {
            perror("accept failed");
            return 1;
        }
        printf("Connection accepted\n");
        memset(clienttan_gelen_message, '\0', sizeof clienttan_gelen_message);
        memset(message, '\0', sizeof message);
        //Receive a reply from the client
        if (recv(sock, clienttan_gelen_message, 200, 0) < 0)
        {

        }
        printf("Clienttan gelen mesaj: %s\n\n\n", clienttan_gelen_message);   

        // Send some data
        //sprintf(serverResponse, "HTTP/1.0 200 OK\r\n\r\n%s\r\n", serverResponseXmlData);
        sprintf(serverResponse, "HTTP/1.0 200 OK\r\n\r\n%s\r\n", serverResponseXmlData2);

        if (send(sock, serverResponse, strlen(serverResponse), 0) < 0)
        {
            printf("Send failed");
            sprintf(response404, "HTTP/1.0 404 Not Found\r\n");
            send(sock, response404, strlen(response404), 0);
            return 1;
        }
        //closesocket(sock);
        Sleep(1000); // Note uppercase 'S'
    }

    closesocket(sock);
    WSACleanup();
    return 0;
}

我设法只是向浏览器发送了一个简单的文本，但不知道如何发送表单以便在浏览器端填写它。我在互联网上的研究没有产生任何结果。

任何人都可以帮我解决这个问题吗？
