How do you set both proxy and audience?

[scottkuhl]

The simplest way of setting up identity for a web API that needs to set the audience is this:

services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
.AddMicrosoftIdentityWebApi(configuration.GetSection("AzureAd"));

"AzureAd":
  "Instance": "..."
  "Domain": "..."
  "TenantId": "..."
  "ClientId": "..."
  "Audience": "...:

But when you need to set a proxy there appears to be no constructor that simply takes the configuration section. So, all values need to be setup manually. Something like this:

services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
  .AddMicrosoftIdentityWebApi(options =›
  {
    options.BackchannelHttpHandler = new HttpClientHandler
    {
      Proxy = new WebProxy("...")
      {
        BypassProxyOnLocal = true,
        UseDefaultCredentials = true
      }
    };
  }, options =>
  {
    options.Instance = configuration.GetSection("AzureAD:Instance").Value ?? string.Empty;
    options.Domain = configuration.GetSection("AzureAD:D in"). Value ?? string.Empty;
    options.TenantId = configuration.GetSection("AzureAD:TenantId").Value ?? string.Empty;
    options.ClientId = configuration.GetSection("AzureAD:ClientId").Value ?? string. Empty;
    //options.Audience = configuration.GetSection("AzureAD:Audience").Value ?? string.Empty;
});

But the Audience value is not available under options.

How can you set both the proxy and audience?

BTW, I do know this is a possible workaround to set the proxy for the entire app. But I am looking for guidance on setting it just on the identity.

Environment.SetEnvironmentVariable("HTTP_PROXY", ...);
Environment.SetEnvironmentVariable("HTTPS_PROXY", ...);
