彦祖们，这个响应头的 location 怎么获取啊？

[mingtdlb]

RT，怎么获取 location 呀？求指教

[root@centos ~]# cat t.py
import requests
headers = {
    "User-Agent": "Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/92.0.4515.107 Safari/537.36 Edg/92.0.902.62"
}
s = requests.session()
r = s.get('http://jd.com/',
headers=headers,
allow_redirects=False)
print (r.status_code)
r_url = r.headers["Location"]
print (r_url)

执行报错了

日志上看 get 时候就报错了，程序走不到下面

[Ptu2sha]

..百度一下错误原因就知道连接被重置了 和你代码获取无关

[mingtdlb]

@Ptu2sha ？上面写了啊，被对方重置了。我的意思是要怎么解决

[Cusmate]

代码获取方式没问题，你要解决的是什么问题？

[initd]

s = sessions.Session()

更好的写法是
r = requests.get

我们可能不是同一个版本的 requests，所以多看文档

[toaruScar]

截图里面请求的不是 22.22.22.22 ，而是 jd.com ？
你可以试试看在浏览器里请求 jd.com ，成功之后把浏览器请求时用了的 headers 全抄过去

[mingtdlb]

@Cusmate 想要拿到响应头 location 的值，目的是拿到 location 值中的 token 值

[Cusmate]

@mingtdlb 建议直接用 curl，简单又快捷

[Jwyt]

@initd 更好的写法？。。你不会是不知道 session 啥意思吧

[muzuiget]

链接被重置，本来就连不上，换个 url 吧。

[mingtdlb]

@muzuiget
@toaruScar
这个认证，在浏览器中，就是随便使用一个 url，只要不是 https 的都行，然后他会自动跳转到认证页面。认证服务器并没有给当独的认证地址。

[mingtdlb]

@Cusmate 开始使用 curl 发 HEAD 请求的，但是也是直接给我重置了...

[Cusmate]

不清楚了，我把你的 python 代码原样复制下来执行是没问题的，确实是其它原因导致网络请求中断。

[Jwyt]

你自己的网络问题吧，我试了下正常的啊
