requests s.headers.update(headers) 更新headers

高级用法:

会话对象:

我们来跨请求保持一些cookie:



import requests
import json
import re
s=requests.session()
print s.headers

C:\Python27\python.exe C:/Users/TLCB/PycharmProjects/untitled/mycompany/Django/a12.py
{'Connection': 'keep-alive', 'Accept-Encoding': 'gzip, deflate', 'Accept': '*/*', 'User-Agent': 'python-requests/2.18.4'}

Process finished with exit code 0



import requests
