'''
需求：编写登陆接口
1. 用户输入帐号密码进行登陆
2. 用户信息保存在文件内
3. 用户密码输入错误三次后锁定用户
'''
#方法一
# def login():
#     i = 0
#     while i<3:
#         name = input("请输入账号：")
#         pwd = input("请输入密码：")
#         with open("userinfo.txt","r+") as f:
#             for line in f.readlines():
#                 s = line.strip().split("|")
#                 username = s[0]
#                 password = s[1]
#             if name == username and pwd == password:
#                 print("login success")
#                 break
#             else:
#                 print("login fail")
#                 i += 1
# login()


#方法二

import sys
name = input("请输入账号：")
lockfile = open("userclock.txt","r+")
lock_list = lockfile.readlines()
for lock_info in lock_list:
    lock = lock_info.strip()
    if name in lock:
        sys.exit("账号已锁定，请联系管理员")

userfile = open("userinfo.txt","r+")
user_list = userfile.readlines()
key = []
value = []
for user_info in user_list:
    user = user_info.strip().split("|")
    key.append(user[0])
    value.append(user[1])
    userdic = dict(zip(key,value))
    #print(userdic.keys())
if name in userdic.keys():
    i = 0
    while i<3:
        pwd = input("请输入密码")
        if pwd == userdic[name]:
            print("登录成功")
            break
        else:
            print("登录失败")
            i +=1
    else:
        lockfile.write(name+'\n')
        sys.exit("账号已锁")
else:
    sys.exit("账号不存在")

lockfile.close()
userfile.close()

'''
1.接收用户的username并赋值给变量
2.打开文件，读取用户名密码，赋值给一个字典，这个字典的key是用户名，密码是value
3.先判断是否存在这个key，不存在提示登录失败，并提示用户设置一个密码，将其追加到字典里，最后将字典写入到文件
4.如果存在这个key，提示用户输入密码，用这个密码去和对应的key值得value对比，如果一致，提示登录成功，如果不一致，提示密码错误
