RestSharp忽略.NET Core上的系统代理（例如Fiddler） [英] RestSharp ignoring system proxy (for example Fiddler) on .NET Core

问题描述

我想用Fiddler检查HTTP流量，但是没有捕获任何HTTP流量，我的测试代码是：

I want check the http traffic with Fiddler, but no any http traffic captured, my testing codes:

private static void ByRestSharp()
{
    var restClient = new RestClient("https://jsonplaceholder.typicode.com");
    var request = new RestRequest("posts", Method.GET);
    var response = restClient.Get<List<Post>>(request);
    Console.WriteLine("{0} posts return by RestSharp.", response.Data.Count);
}

但是在我改用HttpClient之后，Fiddler可以捕获HTTP流量，示例代码：

But after I changed to use HttpClient, Fiddler can capture the http traffic, sample codes:

private static void ByHttpClient()
{
    var httpClient = new HttpClient();
    using (var req = new HttpRequestMessage(HttpMethod.Get, "https://jsonplaceholder.typicode.com/posts"))
    using (var resp = httpClient.SendAsync(req).Result)
    {
        var json = resp.Content.ReadAsStringAsync().Result;
        var users = SimpleJson.SimpleJson.DeserializeObject<List<Post>>(json);
        Console.WriteLine("{0} posts return by HttpClient.", users.Count);
    }
}

这是RestSharp还是Fiddler的问题？

Is this a issue of RestSharp or Fiddler?

推荐答案

RestSharp支持的系统代理，直到我们移至.NET Standard。然后，我们在.NET Core上遇到代理问题，然后完全删除了系统代理。我们在Github上打开了问题，您可以在那里查看进度。

RestSharp supported system proxy until we moved to .NET Standard. Then, we got issues with proxy on .NET Core and then using the system proxy was removed entirely. We have an issue opened on Github and you can check the progress there.

但是，显式设置代理应该适用于完整的.NET Framework，请检查此问题。

However, explicitly setting the proxy should work for full .NET Framework, check this issue.

该问题的代码已被确认有效：

Code from the issue, which is confirmed to be working:

var client = new RestClient("http://www.google.com");
client.Proxy = new WebProxy("127.0.0.1", 8888);
var req = new RestRequest("/", Method.GET);
var resp = client.Execute(req);

更新2018-05-31： RestSharp 106.3使用的是默认代理也可以自动在.NET Core上。经过Fiddler的测试。

Update 2018-05-31: RestSharp 106.3 is using the default proxy on .NET Core also, automatically. Tested with Fiddler.
