c# - 在 ASP.NET MVC C# 中的 Saber 中设置授权 header 和访问数据响应

Question

我正在构建一个网站来使用 Insta Flight Search API 搜索航类数据军刀。在彻底阅读了他们提供的文档并测试了 API Explorer 中的 API 之后一切都完美地工作，让我确切地知道 API 将如何工作。

首先，我刚刚创建了一个简单的表单，其中包含 2 个提供来源和目的地 IATA 代码的选择框，以及 2 个提供出发和返回日期的日期输入框。一个多星期以来，我一直在寻找解决方案并尝试了我找到的各种解决方案，但每次我都收到 400 BAD REQUEST 或 401 UNAUTHORIZED 响应。

我还检查了 Demo Gallery但在撰写本文时，没有 C# 示例，即使在 Stack-Overflow 上也只有 78 个问题标记为 saber，只有 1 个问题标记为 saber 和 C#

我联系了支持人员，但收到了回复。

Please bear in mind that we do not provide code support. Could you please share the XML (Sabre) files?

我知道我遗漏了一些非常愚蠢的东西，但在尝试了我能想到的一切之后，我向社区寻求帮助。我附上了两个代码文件。

注意:注释的代码代表我尝试过的各种方法

Controller 代码:

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();
    }
}
}

其他最接近我的问题，但没有解决我的问题的 Stack Overflow 问题。

最终编辑

在与可能的解决方案进行了数周的斗争之后，我在响应的格式中找到了答案。一个 JSON 对象将对象作为字符串包含在 "包围中，但整个响应也是一个字符串，这使得内部 "包围到\"

但上个月让我意识到需要为 ASP.NET MVC C# 中的开发人员提供适当的 Saber 教程，因此我将为其他同行发布一篇博文和一个 Nuget 包。我会在链接上线后分享这些链接。

Answer 1

以下代码对我来说工作正常。

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);
    }
}
