【python socket】TCP客户端断线重连

主要思想：用一个线程每1s发一组数据，判断当前服务端是否还存活，如果活着就等1s再继续发数据，如果服务端挂了就等2s重新connect

def Thread_ConnectSocket_CAN():
    while True:
        try:
            global tcp_client_socket_CAN
            tcp_client_socket_CAN = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
            tcp_client_socket_CAN.connect(("127.0.0.1", 6000))

            while True:
                try:
                    sendData = "7E7EC2880001004BAA55"
                    tcp_client_socket_CAN.send(bytes.fromhex(sendData))
                    time.sleep(1)
                except:
                    break
        except socket.error:
            print("未连接，尝试重连中..")
            time .sleep(2)
        except Exception as e:
            print(e)
            time.sleep(2)

if __name__ == '__main__':
    # 启动线程
    thread_obj_CAN = threading.Thread(target=Thread_ConnectSocket_CAN)
    thread_obj_CAN.setDaemon(True)
    thread_obj_CAN.start()
