在Python中,可以使用socket.recv()方法来接收数据。该方法接收指定字节数的数据,并返回一个包含接收数据的字节数组。如果没有数据可接收,则该方法会阻塞等待数据到达。示例代码如下:...
client.close 服务器: import socket server= socket.socket() server.bind(('10.211.55.31',8000)) server.listen() sock, addr = server.accept() data = "" while True: temp_data = sock.recv(1024) print(temp_data) if temp_data: data += temp_data.decode("utf8") ...
with client_socket: print(f"Connected by {client_address}") while True: # 接收客户端数据 data = client_socket.recv(1024) if not data: break # 将接收到的数据回显给客户端 client_socket.sendall(data) if __name__ == "__main__": ...

使用Python的`socket`模块,通过`send()`发送字节串至服务器,如`client_socket.send(message_bytes)`;用`recv()`接收数据,如`received_data = client_socket.recv(buffer_size)`。异常处理确保网络错误时程序健壮性,例如`try-except`捕获`socket.error`。理解和掌握这些基础操作对于构建稳定的TCP客户端至关重要。
