搭建服务,接收json data，写一个客户端和一个服务端

服务端代码：

import socket
import json

HOST = '127.0.0.1'
PORT = 8888

def handle_request(request):
    try:
        data = json.loads(request)
        # 在这里处理客户端发送的数据
        # 可以根据数据的内容执行相应的操作
        # 这里只是简单地将数据打印出来
        print(data)
        return json.dumps({'success': True})
    except ValueError:
        return json.dumps({'success': False, 'error': 'Invalid JSON'})

def start_server():
    server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    server_socket.bind((HOST, PORT))
    server_socket.listen(1)
    print('Listening on port %s ...' % PORT)

    while True:
        client_socket, address = server_socket.accept()
        print('Accepted connection from %s:%s' % address)
        request = client_socket.recv(1024).decode()
        response = handle_request(request)
        client_socket.send(response.encode())
        client_socket.close()

if __name__ == '__main__':
    start_server()

客户端代码：

import socket
import json

HOST = '127.0.0.1'
PORT = 8888

def send_request(data):
    client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    client_socket.connect((HOST, PORT))
    request = json.dumps(data)
    client_socket.send(request.encode())
    response = client_socket.recv(1024).decode()
    response_data = json.loads(response)
    if response_data.get('success'):
        print('Request succeeded')
    else:
        print('Request failed: %s' % response_data.get('error'))
    client_socket.close()

if __name__ == '__main__':
    data = {'name': 'John', 'age': 30}
    send_request(data)

运行服务端代码后，运行客户端代码，就可以向服务端发送数据了。服务端会将接收到的数据打印出来，并返回一个成功或失败的消息给客户端。
