如何使用python客户端和C服务器通过套接字正确发送图像

import cv2
import socket
import struct
import pickle

client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_ip = '服务器IP地址'
server_port = 服务器端口号
client_socket.connect((server_ip, server_port))

image = cv2.imread('图像文件路径')

data = pickle.dumps(image)

data_size = struct.pack('!I', len(data))

client_socket.sendall(data_size)
client_socket.sendall(data)

    int server_socket, client_socket;

    socklen_t client_address_length = sizeof(client_address);
    char buffer[BUFFER_SIZE];

    // 创建套接字
    server_socket = socket(AF_INET, SOCK_STREAM, 0);
    if (server_socket == -1) {
        perror("Failed to create socket");
        exit(EXIT_FAILURE);

    server_address.sin_family = AF_INET;

    // 绑定套接字到服务器地址和端口
    if (bind(server_socket, (struct sockaddr *)&server_address, sizeof(server_address)) < 0) {

    if (client_socket < 0) {

    }

    // 接收图像数据的长度
    int data_size;

        exit(EXIT_FAILURE);
    }

    // 处理图像数据
    // ...

    // 关闭套接字
    close(client_socket);
    close(server_socket);

    return 0;
