asp.net core defaultProxy

问题描述

在 net 4.5 中，我们正在使用这样的代理:

In net 4.5 we are working with proxy like this:

<system.net>
    <!-- -->
    <defaultProxy enabled="true" useDefaultCredentials="false">
        <proxy usesystemdefault="True" proxyaddress="http://192.168.1.1:8888" bypassonlocal="True" autoDetect="False" />
        <module type="CommonLibrary.Proxy.MyProxy, CommonLibrary, Version=1.0.0.0, Culture=neutral" />
    </defaultProxy>

    <settings>
        <httpWebRequest useUnsafeHeaderParsing="true" />
        <servicePointManager expect100Continue="false" />
    </settings>
</system.net>

但是在 asp.net core 或 test 中我们找不到像上面这样的解决方案有人可以帮我吗?

推荐答案

虽然在可以使用 HttpClientHander 时手动设置代理工作，但默认所有请求都不需要代码，就像你可以在 .NET Framework 中做目前是不可能的.如果您使用的是不公开此功能的库，那就太可惜了.

Whilst manually setting the proxy works when it's possible to use a HttpClientHander, defaulting all requests to do so without code, like you could do in the .NET Framework is currently not possible. Which is bummer if you're using a library that doesn't expose this functionality.

谢天谢地，从 .NET Core 3.0 开始，只需设置环境变量就可以实现这一点(即，其行为与 Linux 一直有效):https://github.com/dotnet/corefx/issues/37187

Thankfully, from .NET Core 3.0, this will be possible simply by setting environment variables (i.e. behaves exactly as Linux has worked forever): https://github.com/dotnet/corefx/issues/37187

或者，https://github.com/dotnet/corefx/issues/36553 在 HttpClient 上添加了一个新的静态 DefaultWebProxy 属性，这将允许您通过代码完成相同的事情.这也将在 Core 3.0 中提供.

Alternatively, https://github.com/dotnet/corefx/issues/36553 added a new static DefaultWebProxy property on HttpClient that will allow you to accomplish the same thing via code. This will also be available in Core 3.0.
