Python中JsonPath提取器和正则提取器

import re
import requests

a = requests.get("http://www.baidu.com")
# print(a.text)

b = re.search('charset=(.*?)><meta http-equiv=X-UA-Compatible content=IE=Edge>', a.text)
print(b)
print(b.group())
print(b.groups())
print(b.group(1))

token = re.search('"token":"(.*?)",',res.text)[1]
print("token1:%s",%token)

token = re.findall('"token":"(.*?)",'res.text)
print("token2:%s",%token)
