Python模块【加密方式、写入日志、jsonpath模块】

一、jsonpath模块

 1 import jsonpath
 2 
 3 CHJ = {
 4     "money":19000,
 5     "house":{
 6         "beijing":["三环","四环","五环"],
 7         "shanghai":["静安区","浦东新区"],
 8         "house":{
 9             "beijing":["三环","四环","五环"],
10             "shanghai":["静安区","浦东新区"]
11         }
12     },
13     "car":["bmw",'benz','audi','byd'],
14     "pets":[
15         {"name":"张三","type":"dog"},
16         {"name":"lisi","type":"nan"},
17         {"name":"Test","type":"xi"},
18         {"name":"zhuge","type":"bei"},
19     ]
20 }
21 #jsonpath
22 #$.pets[0].type
23 result  = jsonpath.jsonpath(CHJ,"$.pets[3].type")       
24 #result  = jsonpath.jsonpath(CHJ,"$..house")
25 print(result)

二、写入日志模块

 1 from loguru import logger
 2 import sys
 3 
 4 logger.remove() #把默认的配置删掉
 5 fmt = '[{time}][{level}][{file.path}:line:{line}:function_name:{function}] ||msg={message}'
 6 #
 7 logger.add(sys.stdout,format=fmt,level="ERROR")
 8 logger.add("wsc.log",format=fmt,level="DEBUG",encoding="utf-8",enqueue=True,rotation="1 day",retention="7 days")
 9 #enqueue 异步写入
10 #系统标准输出
11 # rotation可以设置大小，超过多大就产生一个新文件 1 kb ,500 m ,1 g
12 # rotation可以多长时间，1 day   1 hour
13 # rotation几点创建新文件，00:00  1:00
14 
15 # retention = 7 days #多长时间后会删除以前产生的日志,当前的日志不会受影响
16 
17 logger.error("=======错误日志======")
18 logger.warning("======警告日志======")
19 logger.info("======正常提示日志======")
20 logger.debug("======打印日志较多======")

三、加密模块

　　1. base64加解密

1 import base64
2 print("======加密=================================")
3 s = "chj123CHJ963"
4 result = base64.b64encode(s.encode()).decode()
5 print(result)
6 print("======解密=================================")
7 s1 = "Y2hqMTIzQ0hKOTYz"
8 result = base64.b64decode(s1).decode()
9 print(result)

　　2. md5加密

1 import hashlib
2 
3 j = "123456"
4 bj = j.encode()
5 # m = hashlib.md5( bs )
6 j = hashlib.sha256( bj )
7 # m = hashlib.sha512( bs )
8 # m = hashlib.sha224( bs )
9 print(j.hexdigest())

　　3. 加密加盐

 1 import hashlib
 2 
 3 #加盐
 4 s = "123456" + "@￥gbg3t23!#"
 5 bs = s.encode()
 6 m = hashlib.sha256( bs )
 7 def my_md5(s,salt=""):
 8     new_s = str(s) + salt
 9     m = hashlib.md5(new_s.encode())
10     return m.hexdigest()
11 print(m.hexdigest())
