Python：如何从请求头中提取值？

Question

我正在尝试使用python请求登录到http://www.nike.com。我首先需要获得的访客ID使用的网址的一部分，为电子后登录请求。你知道吗

我唯一能找到访客ID的地方是在请求头上，或者从名为会话.html（倒数第二行）：

Upgrade-Insecure-Requests: 1 DNT: 1

这是我的密码会话.html地址：

def nike():

    headers = {
        'Host': 'unite.nike.com',
        'User-Agent': 'Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:71.0) Gecko/20100101 Firefox/71.0',
        'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
        'Accept-Language': 'en-US,en;q=0.5',
        'Accept-Encoding': 'gzip, deflate, br',

        'Referer': 'https://www.nike.com/',
        'Upgrade-Insecure-Requests': '1',
        'DNT': '1'
    }

    s = requests.Session()
    sessionresp = s.get("https://unite.nike.com/session.html", headers=headers)

    print(sessionresp.cookies)

nike()

但这段代码只提取响应cookies。我不知道如何访问请求头或请求cookies。如何访问请求Cookie或标头以便提取访问者ID？你知道吗

我还将包括显示访问者ID的登录参数：

Answer 1

我已经检查了visitData头。实际上等于X-Request-Id

检查以下内容：

因此您可以通过以下方式获得：

import requests

r = requests.get('https://www.nike.com/')

print(r.headers['X-Request-Id'])

你现在所需要的就是使用requests.Session()
