HttpClient 'Platform.AccessDeniedException'

CauchYCauchY ✭
in Questions And Answers

Hi all,
my HttpClient is working in a UWP app but it fails inside a Hololense build:
Unhandled 'Platform.AccessDeniedException' exception caught! - Access denied

    Uri host = new Uri("http://foo/bar");
    var myClient = new HttpClient();
    string response = await myClient.GetStringAsync(host);

I'm using the Holo emulator. Edge has access to the internet.
Do I need some sort of permission?

Thanks.

    @CauchY,
    It sounds like you need to enable internet capabilities for your application. To do this:

    • Go to Edit > Project Settings > Player
    • Select the Windows Store icon in the Inspector
    • Expand Publishing Settings and scroll down the Capabilities
    • Check InternetClient (and InternetClientServer if just InternetClient is not sufficient)

    Then build as usual in Unity and Visual Studio.

    Thanks!
    David

    If I use the UnityWebRequest/WWW class, it works in Unity's Game mode. But it says "Cannot resolve destination host" in the HoloEmulator.

    Weird stuff is going on inside the Hololense. Everything works great until I try to use it with the Hololens.

    Thanks for the tip, I didn't think about that.
    WWW works now.
    Unfortunately, awaiting the HttpClient still not working. I even disabled the firewall for testing.
