使用Python请求在请求之间设置新的Cookie [英] Set new cookie between requests with Python Requests

问题描述

我现在这样做，但它在最后一行与 TypeError：expected string or buffer 失败。

I'm doing this right now, but it fails at that last line with TypeError: expected string or buffer.

import requests
from urllib.parse import urlparse

url = 'some url'

s = requests.Session()
s.headers.update({
    'Origin':urlparse(url).netloc,
    'Referer':url
})


r = s.get(url)

s.cookies['cookie1'] = 25
s.cookies['cookie2'] = 25

r = s.post(
    url,
    {'param':'value1', 'param2':'value2'},
    headers={'X-Requested-With':'XMLHttpRequest'}
)

code> Session ？我对Python很新，所以我可能会困惑的东西。使用Python 3.4.1。

What's the correct way to update the cookies when using Session? I'm pretty new to Python, so I might have confused something. Using Python 3.4.1.

跟踪回溯：

推荐答案

p> Cookie值是字符串，而不是整数。将其设置为：

Cookie values are strings, not integers. Set them as such:

s.cookies['cookie1'] = '25'
s.cookies['cookie2'] = '25'

演示：

>>> import requests
>>> from urllib.parse import urlparse
>>> url = 'http://httpbin.org/cookies'
>>> s = requests.Session()
>>> s.headers.update({
...     'Origin':urlparse(url).netloc,
...     'Referer':url
... })
>>> r = s.get(url)
>>> s.cookies['cookie1'] = '25'
>>> s.cookies['cookie2'] = '25'
>>> r = s.get(url, headers={'X-Requested-With':'XMLHttpRequest'})
>>> print(r.text)
{"cookies": {"cookie1": "25", "cookie2": "25"}}
