Nicht in der Lage Ausgabeergebnis von Microsoft Text Analytics Thema Sentiment Erkennung zu erhalten

Question

Ich verwende die Text Analytics-APIs, um Stimmung und Punkte zu erkennen, indem Sie das JSON-Objekt übergeben. Laut den Informationen, die in dem Dokument erwähnt werden, wenn die Antwort als 200 erhalten wird, gibt api das korrekte Ergebnis und den Stimmungswert zurück. Nun ist die Frage, die ich die Antwort als 200 bin immer, aber ich bin nicht das Gefühl bekommen ein Tor für weitere nutzen rocesssing

Request-Objekt:

{ "documents": [{ "language": "en", "id": 1, "text": "I had a wonderful experience" }, { "language": "en", "id": 2, "text": "It was an Ugly picture" }] } 

response object: 

{ 
    "Version": { 
     "Major": 1, 
     "Minor": 1, 
     "Build": -1, 
     "Revision": -1, 
     "MajorRevision": -1, 
     "MinorRevision": -1 
    }, 
    "Content": { 
     "Headers": [{ 
      "Key": "Content-Type", 
      "Value": ["application/json; charset=utf-8"] 
     }] 
    }, 
    "StatusCode": 200, 
    "ReasonPhrase": "OK", 
    "Headers": [{

    }, { 
     "Key": "x-ms-transaction-count", 
     "Value": ["1"] 
    }, { 
     "Key": "x-aml-ta-request-id", 
     "Value": ["f78d8964-a2a1-4b67-aaa5-1a92b6ea25f9"] 
    }, { 
     "Key": "X-Content-Type-Options", 
     "Value": ["nosniff"] 
    }, { 
     "Key": "apim-request-id", 
     "Value": ["0882ea1e-6c31-4a2c-b3c0-1963ec0734c1"] 
    }, {

    }, { 
     "Key": "Date", 
     "Value": ["Sat, 01 Jul 2017 19:49:10 GMT"] 
    }], 
    "RequestMessage": { 
     "Version": { 
      "Major": 1, 
      "Minor": 1, 
      "Build": -1,

      "MajorRevision": -1, 
      "MinorRevision": -1 
     }, 
     "Content": { 
      "Headers": [{ 
       "Key": "Content-Type", 
       "Value": ["application/json"] 
      }, { 
       "Key": "Content-Length", 
       "Value": ["135"] 
      }] 
     }, 
     "Method": { 
      "Method": "POST" 
     }, 
     "RequestUri": "https://westus.api.cognitive.microsoft.com/text/analytics/v2.0/sentiment", 
     "Headers": [{ 
      "Key": "Ocp-Apim-Subscription-Key", 
      "Value": ["************************"] 
     }], 
     "Properties": {} 
    }, 
    "IsSuccessStatusCode": true 
} 

Unten ist der Code weiter zu JSON-Objekt und ruft WebAPI

var client = new HttpClient(); 
      var queryString = HttpUtility.ParseQueryString(string.Empty); 
    enter code here 
      // Request headers 
      client.DefaultRequestHeaders.Add("Ocp-Apim-Subscription-Key", "******************"); 
      var uri = "https://westus.api.cognitive.microsoft.com/text/analytics/v2.0/sentiment"; 

      HttpResponseMessage response; 
      Document doc = new Document(); 
      byte[] byteData = Encoding.UTF8.GetBytes(doc.ReturnJson());      

      using (var content = new ByteArrayContent(byteData)) 
      { 
       content.Headers.ContentType = new MediaTypeHeaderValue("application/json"); 
       response = await client.PostAsync(uri, content); 
       response.ToJSON(); 
      }

Answer 1

Ich habe gerade einen Test hier und es funktioniert gut:

using System; 
using System.Net.Http.Headers; 
using System.Text; 
using System.Net.Http; 
using System.Web; 
using System.IO; 

namespace CSHttpClientSample 
{ 
    static class Program 
    { 
     static void Main() 
     { 
      MakeRequest(); 
      Console.WriteLine("Hit ENTER to exit..."); 
      Console.ReadLine(); 
     } 

     static async void MakeRequest() 
     { 
      var client = new HttpClient(); 
      var queryString = ""; 

      // Request headers 
      client.DefaultRequestHeaders.Add("Ocp-Apim-Subscription-Key", "YOUR KEY IN HERE"); 

      var json = "{ \"documents\": [ {  \"language\": \"en\",  \"id\": \"1\",  \"text\": \"I had a wonderful experience\" }, {  \"language\": \"en\",  \"id\": \"2\",  \"text\": \"It was an Ugly picture\" } ]}"; 


      var uri = "https://westus.api.cognitive.microsoft.com/text/analytics/v2.0/sentiment?" + queryString; 

      HttpResponseMessage response; 

      // Request body 
      byte[] byteData = Encoding.UTF8.GetBytes(json); 

      using (var content = new ByteArrayContent(byteData)) 
      { 
       content.Headers.ContentType = new MediaTypeHeaderValue("application/json"); 
       response = await client.PostAsync(uri, content); 

       Console.WriteLine(response.Content.ReadAsStringAsync().Result); 
      } 

     } 
    } 
} 

OUTPUT

Hit ENTER to exit...
