How to use accept function

accept is a function commonly used in computer network programming, especially when using sockets for server-side programming. Its main purpose is to accept connection requests from clients. In Python's socket module, the prototype of the accept function is "socket.accept()".

accept is a function commonly used in computer network programming, especially when using sockets for server-side programming. Its main purpose is to accept connection requests from clients.

In Python's socket module, the prototype of the accept function is as follows:

socket.accept()

This function will block (or wait) until there is a client The client attempts to establish a connection with it. Once a client is connected, the accept function returns a tuple containing two elements. The first element is the new socket object, representing the connection to the client, and the second element is the client's address.

Example usage:

import socket  
  
def server_program():  
    # 创建一个TCP/IP套接字  
    server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)  
      
    # 绑定到特定地址和端口  
    server_address = ('localhost', 12345)  
    print('启动服务器在{}端口'.format(server_address))  
    server_socket.bind(server_address)  
      
    # 监听连接  
    server_socket.listen(1)  
      
    while True:  
        print('等待连接...')  
        client_socket, client_address = server_socket.accept()  # 阻塞直到有连接  
        print('接受到来自{}的连接'.format(client_address))  
          
        # 处理客户端请求...  
        # ...  
          
        client_socket.close()  
  
if __name__ == '__main__':  
    server_program()

In the above code, the server-side program will wait and accept connections from clients. When a client connects, the accept function returns a new socket (representing the connection to the client) and the client's address. You can then use the returned client_socket to communicate with the client.
