Question

代码尝试通过http请求从php脚本下载文本。由于代码应该在带有Windows IoT的Raspberry Pi上运行，我必须使用GetResponseAsync（）。如果我在没有凭据的情况下使用它（Http源是公共的），它工作正常。当我添加NetworkCredential的东西时，我得到你在图片中看到的异常。 Screenshot 最后，我希望能够从通过.htaccess保护的http网站加载数据。我希望任何人都有这方面的经验！

namespace HttpGetBeisp1Hta {

public sealed partial class MainPage : Page {

    public MainPage() {
        InitializeComponent();
    }

    private async void ClickMe_Click(object sender, RoutedEventArgs e)
    {
        try {
            await HoleDaten();
        }
        catch(Exception ex) {
            textBlock.Text = ex.ToString();
        }

    }
    private async Task HoleDaten() {

            NetworkCredential myCred = new NetworkCredential("user", "pw");
            CredentialCache myCache = new CredentialCache();
            myCache.Add(new Uri("https://..'my secret uri'../getSave.php"), "Basic", myCred);
            WebRequest request = WebRequest.Create("https://..'my secret uri'../getSave.php");
            request.Credentials = myCache;


            WebResponse response = await request.GetResponseAsync();
            Stream dataStream = response.GetResponseStream();
            StreamReader reader = new StreamReader(dataStream);
            string responseFromServer = reader.ReadToEnd();
            textBlock.Text = responseFromServer;

    }
    }


}

发现它！

我手动修改了标题。用户名和密码需要在base64中添加。使用转换器并用“Hans：Mueller”喂它：

private async Task HoleDaten() {
            WebRequest request = WebRequest.Create("https:// ... ll.php");                
            request.Headers["Authorization"] = "Basic SGFuczpNdWVsbGVy";
            WebResponse response = await request.GetResponseAsync();
            Stream dataStream = response.GetResponseStream();
            StreamReader reader = new StreamReader(dataStream);
            string responseFromServer = reader.ReadToEnd();
            textBlock.Text = responseFromServer;

    }

C＃// GetResponseAsync（）// NetworkCredential // .htaccess在Windows 10 IoT Raspberry Pi 2上
