Python套接字错误10054，连接被远程主机中断

Question

我正在尝试与连接到我的计算机的以太网设备建立通信。当我将套接字连接到设备的IP地址和端口时，连接似乎可以正常工作，但是当我尝试向设备发送命令时，它返回[错误10054-远程主机强行中断了连接]。到目前为止，我的代码是这样的：

import socket
import time
import logging



logging.basicConfig(filename='conn.txt', filemode='w')


logging.warning('Starting...')
address = ('192.168.1.23', 23)
soc = socket.socket(socket.AF_INET, socket.SOCK_STREAM)


ok = soc.connect_ex(address)


if ok == 0:
    logging.warning('Connected to device ' + str(ok))
else:
    logging.warning('Connection failed ' + str(ok))



### send at command
command = 'AT+SENSOR_IDS'
cmd_to_send = command + '\r\n'
cmd_to_send = cmd_to_send.encode('ascii')
logging.warning('Sending at command')

soc.sendall(cmd_to_send)
logging.warning('at command sent, waiting for echo')


# read echo
echo = soc.recv()
logging.warning('received echo: ' + echo)

print('finished')

[当我尝试与另一个soc.connect_ex（address）“重新连接”时，它告诉我该套接字正在使用中。

感谢您的所有帮助。

尝试一下：

import socket
import time
import logging

logging.basicConfig(filename='conn.txt', filemode='w')

logging.warning('Starting...')
address = ('192.168.1.23', 23)
soc = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

try:
    ok = soc.connect_ex(address)

    if ok == 0:
        logging.warning('Connected to device ' + str(ok))
    else:
        logging.warning('Connection failed ' + str(ok))


    ### send at command
    command = 'AT+SENSOR_IDS'
    cmd_to_send = command + '\r\n'
    cmd_to_send = cmd_to_send.encode('ascii')
    logging.warning('Sending at command')

    soc.sendall(cmd_to_send)
    logging.warning('at command sent, waiting for echo')

    # read echo
    echo = soc.recv()
    logging.warning('received echo: ' + echo)
except:
    try:
        soc.close()
        print('Process Finished Succefully')
    except:
        print('Process Finished Socket Exception Occured')
