在ASP.NET MVC中設置授權標題和訪問Sabre中的數據響應C＃

Question

我正在構建一個網站，使用Sabre的Insta Flight Search API來搜索航班數據。在徹底閱讀他們提供的文檔並在API Explorer中測試API之後，所有工作都非常完美，讓我明白API的工作原理。

首先我創建了一個簡單的表單，其中包含兩個提供源和目標IATA代碼的選擇框和兩個日期輸入框，用於指定出發日期和返回日期。我一直在尋找超過一週的解決方案，並嘗試了各種解決方案，但每次我收到400 BAD REQUEST或401 UNAUTHORIZED響應。

我還檢查Demo Gallery但在寫作的時候有對C＃沒有樣品，即使是在棧溢出只有78題標記軍刀，只是1標籤的軍刀和C＃

我聯繫了支持，但收到回覆。

請注意，我們不提供代碼支持。你能分享XML（Sabre）文件嗎？

我知道我錯過了一些非常愚蠢的事情，但在嘗試了所有我能想到的事情後，我正在訴諸社區尋求幫助。我附上兩個代碼文件。

注：評論代碼表示的各種方法我都試過

控制器代碼：

using System; 
using System.Net; 
using System.Net.Http; 
using System.Web.Mvc; 
using System.Threading.Tasks; 

namespace Sabre_sample_1.Controllers 
{ 
    public class HomeController : Controller 
    { 
     public async Task<ActionResult> Index() 
     { 
      if (Request.HttpMethod == "POST") 
      { 
      string Origin = Request.Form["Origin"]; 
      string Destination = Request.Form["Destination"]; 
      DateTime Departure = Convert.ToDateTime(Request.Form["Departure"]); 
      string departuredatestr = Departure.Year.ToString() + "-" + Departure.Month.ToString() + "-" + Departure.Day.ToString(); 
      DateTime Return = Convert.ToDateTime(Request.Form["Return"]); 
      string returndatestr = Return.Year.ToString() + "-" + Return.Month.ToString() + "-" + Return.Day.ToString(); 

      WebClient datawebclient = new WebClient(); 
      string url = "https://" + "api.test.sabre.com/v1/shop/flights?origin=" + Origin + "&destination=" + Destination 
       + "&departuredate=" + departuredatestr + "&returndate=" + returndatestr + "&onlineitinerariesonly=N" 
       + "&limit=10&offset=1&eticketsonly=N&sortby=totalfare&order=asc&sortby2=departuretime&order2=asc" 
       + "&pointofsalecountry=US"; 
      string data = string.Empty; 
      string AccessToken = "*Access Token*"; 
      //datawebclient.Headers.Add("Authorization", "Bearer " + AccessToken); 
      //datawebclient.Headers.Add(HttpRequestHeader.Authorization, "Bearer " + AccessToken); 
      //datawebclient.Headers.Add(HttpRequestHeader.Authorization, AccessToken); 
      //data = datawebclient.DownloadString(url); 

      //HttpClient httpClient = new HttpClient(); 
      //httpClient.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Bearer", AccessToken); 
      //data = await httpClient.GetStringAsync(url); 

      using (var client = new HttpClient()) 
      { 
       //url = "https://www.theidentityhub.com/{tenant}/api/identity/v1"; 
       client.DefaultRequestHeaders.Add("Authorization", "Bearer " + AccessToken); 
       data = await client.GetStringAsync(url); 
       // Parse JSON response. 

      } 

      ViewBag.url = url; 
      ViewBag.data = data; 
      //RedirectResult redirectresult = new RedirectResult(url); 
     } 
     return View(); 
    } 
} 
}

與可能的解決方案中掙扎星期後，我發現了個答案e格式化迴應。一個JSON對象在「封閉中包含對象作爲字符串，但是整個響應也是一個字符串，它使內部」封閉到「。但上個月讓我意識到需要爲開發人員開發適合Saber的教程在ASP.NET MVC C＃中，所以我將發佈博客文章和其他同行的Nuget包。我將在他們生活後分享鏈接。

經過幾周的努力與可能的解決方案，我找到了答案格式的答覆。一個JSON對象在「封閉中包含對象作爲字符串，但是整個響應也是一個字符串，它使內部」封閉到「。但上個月讓我意識到需要爲開發人員開發適合Saber的教程在ASP.NET MVC C＃，所以我會發布的博客文章和NuGet包的其他同行。我曾經爲實時共享的鏈接。

編碼快樂。

Answer 2

以下代碼對我來說工作正常。

FlightObject f = new FlightObject(); 
string URL = "https://api.test.sabre.com/v2/shop/flights?origin=JFK&destination=LAX&departuredate=2016-02-04&returndate=2016-02-20&pointofsalecountry=US&passengercount=2"; 
using (var w = new WebClient()) 
{ 
    w.Headers.Add(HttpRequestHeader.Authorization, token_type + " " + access_token); 
    string str = w.DownloadString(URL); 
    DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(FlightObject)); 
    using (var ms = new MemoryStream(Encoding.Unicode.GetBytes(str))) 
    { 
     f = (FlightObject)serializer.ReadObject(ms); 
    } 
}

假設您首先獲取訪問令牌，使用/v2/auth/token REST service，對吧？

https://developer.sabre.com/docs/read/rest_basics/authentication

此外，你可以試試這個方法？

// Add this on top 
using System.Net.Http.Headers; 
// then...... 
//....... 

    using (var client = new HttpClient()) 
    { 
     client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", AccessToken); 
     data = await client.GetStringAsync(url); 

    }
