Передача учетных данных HttpWebRequest для API Оксфорда

Question

Я пытаюсь подключиться к Oxford Dictionaries API. Я не имея никаких проблем, когда я использую Python с этим кодом:

import requests 
import json 
app_id = 'my id' 
app_key = 'my key' 
language = 'en' 
word_id = 'Ace' 
url = 'https://od-api.oxforddictionaries.com:443/api/v1/entries/' + language  + '/' + word_id.lower() 
r = requests.get(url, headers = {'app_id': app_id, 'app_key': app_key}) 
print("code {}\n".format(r.status_code)) 

Но когда в C# я получаю сообщение об ошибке 403 Ошибка аутентификации с помощью следующего кода:

 HttpWebRequest req = null; 
     string PrimeUrl = "https://od-api.oxforddictionaries.com:443/api/v1/entries/en/" 
     string uri = PrimeUrl+word ; 
     req = (HttpWebRequest)HttpWebRequest.Create(uri); 
     string credentials = String.Format("{0}:{1}", uid, pwd); 
     byte[] bytes = Encoding.ASCII.GetBytes(credentials); 
     string base64 = Convert.ToBase64String(bytes); 
     string authorization = String.Concat("Basic ", base64); 
     req.Headers.Add("Authorization", authorization); 
     req.Method = WebRequestMethods.Http.Get; 
     req.Accept = "application/json";    
     HttpWebResponse HWR_Response = (HttpWebResponse)req.GetResponse(); 

Я проверил идентификатор и ключ правильный, также попробовал все предлагаемое here.

Публикация этого вопроса - мой последний вариант. Спасибо.

Answer 1

Это, как правильно добавить свои учетные данные для разработчиков на запрос - они заголовки:

using System; 
using System.Diagnostics; 
using System.IO; 
using System.Net; 
using System.Text; 

namespace OxfDictionary 
{ 
    class Program 
    { 
     static void Main(string[] args) 
     { 
      HttpWebRequest req = null; 

      string PrimeUrl = "https://od-api.oxforddictionaries.com:443/api/v1/entries/en/"; 
      string uri = PrimeUrl + "robot"; 
      req = (HttpWebRequest)HttpWebRequest.Create(uri); 

      //These are not network credentials, just custom headers 
      req.Headers.Add("app_id", "5a......3"); 
      req.Headers.Add("app_key", "d12............1a0"); 

      req.Method = WebRequestMethods.Http.Get; 
      req.Accept = "application/json"; 

      using (HttpWebResponse HWR_Response = (HttpWebResponse)req.GetResponse()) 
      using (Stream respStream = HWR_Response.GetResponseStream()) 
      using (StreamReader sr = new StreamReader(respStream, Encoding.UTF8)) 
      { 
       string theJson = sr.ReadToEnd(); 
       Debug.WriteLine(theJson); 
       Console.WriteLine(theJson); 
      } 
      Console.ReadKey(); 
     } 
    } 
} 

И результат:
