Python练习-装饰器版-为什么我的用户总被锁定

参考代码如下:

1.用户登录程序流程控制代码:

 1 # 编辑者：闫龙
 2 if __name__ == ‘__main__‘:
 3     import UserLoginFuncation
 4 LoclCount=[];
 5 while True:
 6     UserName = input("用户名:>>")
 7     if(UserLoginFuncation.CheckUserLock(UserName)):
 8         print("用户",UserName,"已被锁定")
 9         continue
10     PassWd = input("密  码:>>")
11     if(UserLoginFuncation.UserInfo(UserName,PassWd)):
12         print("欢迎",UserName,"登陆")
13         break
14     else:
15         LoclCount.append(UserName);
16         print("用户名或密码错误,您还有",3-LoclCount.count(UserName),"次尝试机会")
17     if(LoclCount.count(UserName) == 3):
18         UserLoginFuncation.LockUser(UserName)
19         print("对不起,尝试次数过多",UserName,"用户已被锁定")

2.用户登录程序调用函数(加入装饰器):

 1 # 编辑者：闫龙
 2 import UserLoginDeco
 3 import os
 4 @UserLoginDeco.Jude(2)
 5 def CheckUserLock(UserName):
 6     if(os.path.exists("LockUser")):
 7         with open("LockUser","r",encoding="utf8") as ReadLock:
 8             p = ReadLock.readline().split(",")
 9             if(p.count(UserName) != 0):
10                 return True
11     else:
12         return False
13
14 @UserLoginDeco.Jude(3)
15 def LockUser(UserName):
16     if(os.path.exists("LockUser")):
17         LockFile = open("LockUser", "a", encoding="utf8")
18         LockFile.write(UserName+",")
19         LockFile.close()
20     else:
21         LockFile = open("LockUser", "w", encoding="utf8")
22         LockFile.write(UserName+",")
23         LockFile.close()
24
25 @UserLoginDeco.Jude(1)
26 def UserInfo(UserName,PassWd):
27     with open("UserInfo",mode="r",encoding="utf8") as userinfo:
28         p =  userinfo.readlines()
29         for i in p:
30             i= i.strip().split(":")
31             if(i[0] == UserName and i[1] == PassWd):
32                 return True
33             else:
34                 continue
35         return False

3.用户登录程序装饰器代码:

 1 # 编辑者：闫龙
 2 import time
 3 def Jude(InputType):
 4     def ViewUser(UserLoginFunc):
 5         def PrintUser(*args):
 6             if(InputType == 1):
 7                 while True:
 8                     print("您输入的用户名是",args[0],"密码是",args[1])
 9                     choice = input("请问是否继续登陆(y/n)")
10                     if (choice.lower() == "y"):
11                         res = UserLoginFunc(args[0],args[1])
12                         return res
13                     elif(choice.lower() == "n"):
14                         break;
15                     else:
16                         print("您的选择有误")
17                         continue
18             if(InputType == 2):
19                 print("正在比对用户",args[0],"的信息......")
20                 time.sleep(2)
21                 res = UserLoginFunc(args[0])
22                 return res
23             if(InputType == 3):
24                 print("正在锁定",args[0],"用户")
25                 time.sleep(2)
26                 res = UserLoginFunc(args[0])
27                 return res
28         return PrintUser
29     return ViewUser
