模块（写日志、jsonpath、加密）

1.写日志模块

from loguru import logger
import sys

logger.remove() #把默认的配置删掉

fmt = '[{time}][{level}][{file.path}:line:{line}:function_name:{function}] ||msg={message}'
logger.add(sys.stdout,format=fmt,level="DEBUG")
logger.add("wsc.log",format=fmt,level="DEBUG",encoding="utf-8",enqueue=True,rotation="1 day",retention="7 days")
#enqueue 异步写入
#系统标准输出
# 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
# rotation可以多长时间，1 day   1 hour
# rotation几点创建新文件，00:00  1:00

# 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

logger.debug("我是debug")  #打印信息比较多
logger.info("我是info")  #正常的提示信息
logger.warning("warning") #警告
logger.error("error") #错误

2.jsonpath模块

import jsonpath

wsc = {
    "money":19000,
    "house":{
        "beijing":["三环","四环","五环"],
        "shanghai":["静安区","浦东新区"]
    },
    "car":["bmw",'benz','audi','byd'],
    "pets":[
        {"name":"xiaohei","type":"dog"},
        {"name":"xiaobai","type":"cat"},
        {"name":"xiaofen","type":"cat"},
        {"name":"xiaolan","type":"dog"},
    ]
}

#$.pets[0].type
#result  = wsc["pets"][0]["type"] #原有的方法获取
#result  = jsonpath.jsonpath(wsc,"$.pets[0].type")
#result  = jsonpath.jsonpath(wsc,"$..car")
result  = jsonpath.jsonpath(wsc,"$..beijing")
print(result)

 3.加密模块

import hashlib

s = "123456" + "@￥gbg3t23!#"
bs = s.encode()#把s从unicode编码方式转换成utf-8的编码方式;bs.decode('utf-8') # 解码成unicode编码
m = hashlib.md5( bs )
m = hashlib.sha256( bs )
m = hashlib.sha512( bs )
m = hashlib.sha224( bs )
print(m.hexdigest())

#id mingwen      miwen
# 1   wsc12345   4f6c35f22a199f9189ccea52fffed3b4

#加盐

def my_md5(s,salt=""):
    new_s = str(s) + salt
    m = hashlib.md5(new_s.encode())
    return m.hexdigest()

import base64
s = "wanshu、+@#%chengsdgsdgsdgsdgssgsgsg"
result = base64.b64encode(s.encode()).decode()
print(result)

#d2Fuc2h1Y2hlbmdzZGdzZGdzZGdzZGdzc2dzZ3Nn

s1 = "d2Fuc2h1Y2hlbmdzZGdzZGdzZGdzZGdzc2dzZ3Nn"
result = base64.b64decode(s1).decode()
print(result)
