    RT,怎么获取 location 呀?求指教

    login

    [[email protected] ~]# 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

    ..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

    @Ptu2sha ?上面写了啊,被对方重置了。我的意思是要怎么解决

    代码获取方式没问题,你要解决的是什么问题?

    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

    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

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

    @mingtdlb 建议直接用 curl,简单又快捷

    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。

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

    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。
