Visual Studio 2015中的程序包管理器"407(需要代理身份验证)" [英] Package manager in Visual Studio 2015 "407 (Proxy Authentication Required)"

问题描述

我理解这是一个经常被问到的问题，但是经过数天的研究，我仍未找到解决该特定问题的答案.

我有一个新的ASP.NET 5(Core 1.0)MVC模板，我想每次在包管理器"输出中都添加一个包:

I have a new ASP.NET 5 (Core 1.0) MVC template that I'm trying to add a package to however each and every time I get in the Package Manager output:

Response status code does not indicate success: 407 (Proxy Authentication Required). 

以及以下在解决方案资源管理器顶部:

and the following at the top of solution explorer:

我的设置看起来不错，并且可以在管理解决方案的软件包"屏幕中浏览软件包.

my settings look fine and I am able to browse packages in the 'Manage Packages for Solution' screen.

我了解我被要求提供凭据，那么我应该在哪里输入凭据?另一方面，我机器上的所有其他应用程序都已验证了互联网访问权限，那我为什么要这么做?

I understand I'm being requested to supply credentials so where do I enter them? On the other hand all other applications on my machine have validated internet access, so why should I?

任何想法/指针都非常受欢迎.

Any ideas / pointers are very welcome.

我设法捕获了一个非工作请求(返回407)和一个工作请求，其中唯一的区别是代理授权标头的内容更长.这表明代理身份验证确实存在，但是它使用了不同的协议.

I've managed to capture a non-working request (returning 407) and a working request with the only difference being the content of the Proxy-Authorization header which is longer. This would suggest the proxy authentication does exist but it's using a different protocol.

推荐答案

我必须修改 32位 machine.config(假设VS以32位运行)以添加<system.net>部分但省略<defaultProxy>标记内的任何内容:

I had to modify the 32 bit machine.config (assumption being VS runs in 32 bit) to add the <system.net> section but omitting anything within the <defaultProxy> tag:

<system.net>
    <defaultProxy useDefaultCredentials="True" enabled="True" />
</system.net>

根据 MSDN :

如果defaultProxy元素为空，则将使用Internet Explorer中的代理设置.

If the defaultProxy element is empty, the proxy settings from Internet Explorer will be used.

这对我来说是完美的，因为我机器上的所有其他应用程序都可以正常工作-包括IE.

This is perfect for me as every other application on my machine works - including IE.

manchine.config位置(Win 7):％SYSTEMROOT％\ Microsoft.NET \ Framework \ v4.0.30319 \ Config \ machine.config

manchine.config location (Win 7): %SYSTEMROOT%\Microsoft.NET\Framework\v4.0.30319\Config\machine.config

我解决了这个问题，这要归功于@ user3063127向我指出了正确的方向(您有赞成意见).据我所知，这仅影响DNX项目上的程序包还原，并且在发布RC2时可能会得到修复.
