具體功能原始碼中展現的也非常清楚，我就不一一描述了。

原始碼：

import itchat
import os
import time
import cv2
sendMsg = u"{訊息助手}：暫時無法回覆"
usageMsg = u"使用方法：\n1.執行CMD命令：cmd xxx (xxx為命令)\n" \
           u"-例如關機命令:\ncmd shutdown -s -t 0 \n" \
           u"2.獲取當前電腦使用者：cap\n3.啟用訊息助手(預設關閉)：ast\n" \
           u"4.關閉訊息助手：astc"
flag = 0 #訊息助手開關
nowTime = time.localtime()
filename = str(nowTime.tm_mday)+str(nowTime.tm_hour)+str(nowTime.tm_min)+str(nowTime.tm_sec)+".txt"
myfile = open(filename, 'w')
@itchat.msg_register('Text')
def text_reply(msg):
    global flag
    message = msg['Text']
    fromName = msg['FromUserName']
    toName = msg['ToUserName']
    if toName == "filehelper":
        if message == "cap":
            cap = cv2.VideoCapture(0)
            ret, img = cap.read()
            cv2.imwrite("weixinTemp.jpg", img)
            itchat.send('@
 
[email protected]%s'%u'weixinTemp.jpg', 'filehelper')
            cap.release()
        if message[0:3] == "cmd":
            os.system(message.strip(message[0:4]))
        if message == "ast":
            flag = 1
            itchat.send("訊息助手已開啟", "filehelper")
        if message == "astc":
            flag = 0
            itchat.send("訊息助手已關閉", "filehelper")
    elif flag == 1:
        itchat.send(sendMsg, fromName)
        myfile.write(message)
        myfile.write("\n")
        myfile.flush()
if __name__ == '__main__':
    itchat.auto_login()
    itchat.send(usageMsg, "filehelper")
    itchat.run()
