修改以下代码将视屏发送给服务端并将视频保存到本地#define _CRT_SECURE_NO_WARNINGS #include<iostream> #include <sstream> #include<string> #include <fstream> #include <vector> #include<winsock.h> #pragma

注：为了确保代码的正确性和安全性，以下是修改后的代码：

#define _CRT_SECURE_NO_WARNINGS

#include <sstream>
#include <string>
#include <fstream>
#include <vector>
#include <winsock.h>

void SaveVideo(const std::string& filePath, const std::vector<char>& videoData) {
    std::ofstream file(filePath, std::ios::out | std::ios::binary);
    if (file.is_open()) {
        file.write(videoData.data(), videoData.size());
        file.close();
        std::cout << "Video saved successfully." << std::endl;
    }
    else {

int main() {
    WSADATA wsaData;
    if (WSAStartup(MAKEWORD(2, 2), &wsaData) != 0) {
        std::cerr << "Failed to initialize winsock." << std::endl;
        return 1;
    }

    SOCKET clientSocket = socket(AF_INET, SOCK_STREAM, 0);
    if (clientSocket == INVALID_SOCKET) {
        std::cerr << "Failed to create socket." << std::endl;
        WSACleanup();
        return 1;
    }

    sockaddr_in serverAddress{};
    serverAddress.sin_family = AF_INET;
    serverAddress.sin_port = htons(12345); // 修改为服务端的端口号
    serverAddress.sin_addr.s_addr = inet_addr("127.0.0.1"); // 修改为服务端的IP地址

    if (connect(clientSocket, reinterpret_cast<sockaddr*>(&serverAddress), sizeof(serverAddress)) != 0) {
        std::cerr << "Failed to connect to the server." << std::endl;
        closesocket(clientSocket);
        WSACleanup();
        return 1;
    }

    std::string filePath = "video.mp4"; // 修改为要保存的视频文件路径
    std::ifstream file(filePath, std::ios::in | std::ios::binary);
    if (file.is_open()) {
        std::vector<char> videoData((std::istreambuf_iterator<char>(file)), std::istreambuf_iterator<char>());
        file.close();

        // 发送视频数据到服务端
        if (send(clientSocket, videoData.data(), videoData.size(), 0) == SOCKET_ERROR) {
            std::cerr << "Failed to send video data." << std::endl;
        }
        else {
            std::cout << "Video data sent successfully." << std::endl;
        }

        // 保存视频到本地
        SaveVideo("received_video.mp4", videoData);
    }
    else {
        std::cerr << "Failed to open video file." << std::endl;
    }

    closesocket(clientSocket);
    WSACleanup();

    return 0;
}

请确保以下几点：

1. 修改 `serverAddress.sin_port` 为服务端的端口号。
2. 修改 `serverAddress.sin_addr.s_addr` 为服务端的IP地址。
3. 修改 `filePath` 为要保存的视频文件路径。
4. 确保链接了 `ws2_32.lib` 库。

注意：这是一个简单的示例代码，仅展示了如何将视频数据发送到服务端并将其保存到本地。实际情况可能需要进行更多的错误处理和安全性考虑。
