读取本地json文件,解析json(实例讲解)
模拟用户登录
# data.json 文件同目录下
[
{
"id": 1,
"username": "zhangshan",
"password": "123qwe",
"lock": false
},
{
"id": 2,
"username": "lisi",
"password": "123qwe",
"lock": false
},
{
"id": 3,
"username": "wangwu",
"password": "123qwe",
"lock": false
}
]
import json # 引入模块
count = 1
# 打开一个json文件
data = open("./data.json", encoding='utf-8')
# 转换为python对象
strJson = json.load(data)
flag = False
lockFlag = False
while count <= 3:
username = input("请输入用户名:")
password = input('请输入密码:')
for user in strJson:
if username == user['username'] and password == user['password']:
if not user['lock']:
flag = True
else:
lockFlag = True
break
if flag:
print('登录成功!!')
break
else:
print('账号或密码错误')
count = count + 1
# 输出(注意多层结构)
# print(strJson[0]['id'])
# for item in strJson:
# print(item)
