Question

正如标题所述，我只需要OAuth1.0身份验证的第一部分帮助：获取请求令牌。我在使用C＃的控制台应用程序中执行此操作。我已经为此工作了3天了，我已经尝试过来自互联网的大量样本，但到目前为止还没有任何效果。这是我目前的尝试：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Net.Http;
using System.Net.Http.Headers;


namespace MCAPIClient
{
    class Program
    {
        static void Main(string[] args)
        {
           RunAsync().Wait();
        }

        static async Task RunAsync()
        {
            using (var client = new HttpClient())
            {

                var values = new Dictionary<string, string>
                {
                   { "oauth_consumer_key", "<my consumer key>" },
                   { "oauth_consumer_secret", "<my secret key>" }
                };

                var content = new FormUrlEncodedContent(values);

                var response = await client.PostAsync("https://app.masteryconnect.com/oauth/request_token", content);

                var responseString = await response.Content.ReadAsStringAsync();

                Console.WriteLine(response.Headers);

                Console.WriteLine("Press any key to continue...");
                Console.ReadKey(true);
            }
        }

    }
}

这在使用没有身份验证的API（如http://rest-service.guides.spring.io/greeting）时非常有效，但在运行时会收到401 Forbidden。我错过了什么？顺便说一句，我是API的新手。

您必须拥有密钥和密码，或用户名和密码。它们都是获取access_token非常必要的。我建议使用谷歌邮差工具，它使api的生活更轻松。下面的代码将解决您的问题。

 WebRequest req = WebRequest.Create(url);
        req.Method = "POST";
        req.Headers["Authorization"] = "Basic " + Convert.ToBase64String(Encoding.Default.GetBytes("key:Secret"));
        req.Credentials = new NetworkCredential("username", "password");


        var postData = "grant_type=client_credentials";

        byte[] byteArray = Encoding.UTF8.GetBytes(postData);
        req.ContentType = "application/x-www-form-urlencoded";
        req.ContentLength = byteArray.Length;
        Stream dataStream = req.GetRequestStream();
        dataStream.Write(byteArray, 0, byteArray.Length);
        dataStream.Close();
        WebResponse response = req.GetResponse();
        // Console.WriteLine(((HttpWebResponse)response).StatusDescription);
        dataStream = response.GetResponseStream();
        StreamReader reader = new StreamReader(dataStream);
        string responseFromServer = reader.ReadToEnd();

        Newtonsoft.Json.Linq.JObject o = Newtonsoft.Json.Linq.JObject.Parse(responseFromServer);

        String status = (string)o.SelectToken(".access_token");

使用C＃中的Oauth1从REST API获取请求令牌
