为什么在ASP.NET中调用API仅如果我有小提琴手开？ [英] Why calling API in ASP.NET works only if I have Fiddler open?

问题描述

我打电话在我的指数控制器这样一个API，一切工作正常，只有当我有小提琴手开放。

I am calling an API in my Index Controller like this and everything works fine, only if I have Fiddler open.

public ActionResult Index()
{
    Base model = null;
    var client = new HttpClient();
    var task =
        client.GetAsync(
        "http://example.api.com/users/john/profile")
        .ContinueWith((taskwithresponse) =>
        {
            var response = taskwithresponse.Result;
            var readtask = response.Content.ReadAsAsync<Base>();
            readtask.Wait();
            model = readtask.Result;
        });
    task.Wait();

    return View(model);
}

如果我关闭小提琴手我收到以下错误：

If I close Fiddler I get following error:

无法连接，因为目标机器积极地进行
  拒绝了127.0.0.1:8888

No connection could be made because the target machine actively refused it 127.0.0.1:8888

有一些配置我必须包括，让调用API的作品，即使我没有提琴手打开。

Is there some configuration I have to include, so that calling an API works, even if I don't have Fiddler open.

推荐答案

检查web.config中任何代理配置，并检查是否配置有哪些.NET可能使用系统默认代理。
您可以将它添加到你的web.config禁用代理配置：

Check web.config for any proxy configuration, and also check whether you have configured a system default proxy which .net might use. You can add this to your web.config to disable proxy configuration:

    <system.net>
      <!-- set enabled to true to use the system default proxy -->
      <defaultProxy enabled="false" />
    </system.net>
