Question

我正在尝试使用cURL for Windows 32位（使用SSH版本）从我的工作中访问google.com。我通过我公司的代理服务器进行连接但是我收到了400个代理周期检测错误。有人可以让我知道为什么我会收到此错误。命令＆amp;错误消息如下（代理IP更改为XXXX）：

命令：

%curl -A "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0b7pre) Gecko/20100925 Firefox/4.0b7pre"  -v --proxy-ntlm XXX.XXX.XXX.XXX:8080 -U name:password -I http://www.google.com

输出：

Enter proxy password for user 'name':

对于它的价值，我可以使用所述代理地址通过浏览器连接到google.com。我确信我正确地提供了密码（代理）。

Answer 1

您已通过--proxy参数设置代理，或者通过--proxy-ntlm设置-x参数，请尝试此操作

curl -A "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0b7pre) Gecko/20100925 Firefox/4.0b7pre" -L --proxy http://xxx.xxx.xxx.xxx:8080 --proxy-ntlm -U name:password http://www.google.com

如果您输入新的重定向周期，可以尝试不使用-L参数或设置--max-redirs参数。

Answer 2

我相信你因身份验证而被淘汰。您的工作代理可能需要进行身份验证才能通过它访问网站。

如果您的作品使用Active Directory SSO（单点登录），请尝试使用您的域用户名和密码：

curl --ntlm --user username:password http://www.google.com

或者不，尝试以下基本身份验证：

curl --user username:password http://www.google.com
