`AcquireTokenAsync` 返回 407

Question

如何向AcquireToken 方法添加代理？

public async Task<ActionResult> Index()
{
    const string AUTHORITY_URL =
        @"https://login.microsoftonline.com/{tenancy ID}/oauth2/authorize";
    const string RESOURCE_URL = @"https://analysis.windows.net/powerbi/api";
    const string CLIENT_ID = @"{Client ID}";

    var credential = new UserPasswordCredential("username", "password");
    var authenticationContext = new AuthenticationContext(AUTHORITY_URL);
    var authenticationResult = await authenticationContext.AcquireTokenAsync(RESOURCE_URL, CLIENT_ID, credential);
    return View();
}

当它运行时，它会显示以下黄色屏幕：

The remote server returned an error: (407) Proxy Authentication Required. 

但是，我似乎没有任何方法可以将代理信息添加到 AuthenticationContext 方法中。

您应该改为在 web.config 中执行此操作。

<configuration>  
  <system.net>  
    <defaultProxy>  
      <proxy  
        usesystemdefault="true"  
        proxyaddress="http://user:pass@192.168.1.10:3128"  
        bypassonlocal="true"  
      />  
      <bypasslist>  
        <add address="[a-z]+\.contoso\.com" />  
      </bypasslist>  
    </defaultProxy>  
  </system.net>  
</configuration>
