.NET에서 Mashape API를 사용할 때의 문제

Question

Mashape API를 사용하여 QR 코드를 얻는 데 유용한 코드가 넷에서 발견되었습니다. Here.

그들의 코드는 잘 작동하지만 시도하고 또 다른 Mashape를 사용하도록 변경하면, 나는

"An exceptions occured during the operation, making the result invalid"

오류가 발생합니다. 그리고 내부 예외를 검사하는 것에 대해서.

아래 코드는 링크의 QR 코드를 보여주고 Weather API와 Spotify API를 사용하려고합니다.

private void Button_Click(object sender, RoutedEventArgs e) 
{ 
    WebClient client = new WebClient(); 
    client.UploadStringCompleted += new UploadStringCompletedEventHandler(client_UploadStringCompleted); 
    client.Headers[HttpRequestHeader.ContentType] = "application/x-www-form-urlencoded"; 
    client.Headers["X-Mashape-Authorization"] = "mashape-api-code-goes-here"; 

    StringBuilder postData = new StringBuilder(); 
    // For Spotify (this doesn't work) 
    // postData.AppendFormat("{0}={1}", "q", HttpUtility.UrlEncode(txtArtitst.Text)); 
    // var uri = new Uri("https://mager-spotify-web.p.mashape.com/search/1/artist.json?", UriKind.Absolute); 

    // For Weather info (this doesn't work) 
    postData.AppendFormat("{0}={1}", "_method", HttpUtility.UrlEncode("getForecasts")); 
    postData.AppendFormat("&{0}={1}", "location", HttpUtility.UrlEncode("brisbane")); 
    var uri = new Uri("https://george-vustrey-weather.p.mashape.com/api.php?", UriKind.Absolute); 

    // For QR Code (this works) 
    //postData.AppendFormat("{0}={1}", "content", HttpUtility.UrlEncode("TestQRCode")); 
    //postData.AppendFormat("&{0}={1}", "quality", HttpUtility.UrlEncode("L")); 
    //postData.AppendFormat("&{0}={1}", "type", HttpUtility.UrlEncode("text")); 
    //postData.AppendFormat("&{0}={1}", "size", HttpUtility.UrlEncode("5")); 
    //var uri = new Uri("https://mutationevent-qr-code-generator.p.mashape.com/generate.php?", UriKind.Absolute); 

    client.UploadStringAsync(uri, "POST", postData.ToString()); 
    txtResult.Text = postData.ToString(); 

    progress1.IsIndeterminate = true; 
    button1.IsEnabled = false; 
} 


void client_UploadStringCompleted(object sender, UploadStringCompletedEventArgs e) 
{ 
    progress1.IsIndeterminate = false; 

    var client = sender as WebClient; 
    client.UploadStringCompleted -= client_UploadStringCompleted; 
    string response = string.Empty; 
    if (!e.Cancelled) 
    { 
     try 
     { 
      response = HttpUtility.UrlDecode(e.Result); // seems to error out here - result invalid 
      txtResult.Text = response; 
     } 
     catch (Exception ex) 
     { 
      txtResult.Text = "ERROR : " + ex.Message; 
     } 
    } 

    button1.IsEnabled = true; 
} 

내부 예외는 말한다 :

의 InnerException

당신이 대신 POST의 GET을 시도 했습니까? https://github.com/ismaelc/Mashape_Windows8_Sample/blob/master/App5/App5/MainPage.xaml.cs
