asp.net 不记名令牌身份验证失败

Bearer token authentication failed on asp.net

我正在尝试在网络上发出 GET 请求 api。我建立客户端。问题似乎出在不记名令牌的身份验证上。我已经看过很多帖子,但没有任何效果。

这是我的代码:

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

namespace AuthUsingBearerToken
{
    class Program
{
    static void Main(string[] args)
    {
        RunClient();
        Console.ReadLine();
    }

    static void RunClient()
    {
        using (var client = new HttpClient())
        {
            client.BaseAddress = new Uri("uri");//address of web api
            client.DefaultRequestHeaders.Accept.Clear();//removes all entries from system.net.http.headers...
            client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));//adds an entry to system in json format

            //First Method i tried
            //client.DefaultRequestHeaders.Accept.Add(new AuthenticationHeaderValue("Bearer ", "token from web api));

            //Second method
            // var token = "token from web api";
            // client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", token);

            //Third Method
            //client.DefaultRequestHeaders.Add("Authorization", "Bearer " + token);
            GetPatient(client, "1").Wait();

        }
    }

    public static async Task GetPatient(HttpClient client, string id)
    {
        try
        {
            HttpResponseMessage response = await client.GetAsync(""+id);
            response.EnsureSuccessStatusCode();

            Patient patient = await response.Content.ReadAsAsync<Patient>();

            Console.WriteLine("Id: {0}\tName: {1}", patient.id, patient.patient_name);

        }
        catch (HttpRequestException e)
        {
            Console.WriteLine("{0}", e.Message);
            throw;
        }
    }


}

我的问题是:

如何制作一个带有令牌认证的Bearer? 还是我做的不对?

谢谢!

您将需要 POST 对您的网络 api 授权端点(例如“\token”)的有效请求,其中包含以下 http body 键值对:username, password, client_id and grant_type=password。 (确保遵循您请求的 header 中的 Content-Type)

为此使用 await client.PostAsync("token", content);

如果授权成功,您将收到一个回复​​access_token。您可以使用令牌 object 反序列化为 (ApiToken = await JsonConvert.DeserializeObject<Token>(response.Content.ReadAsStringAsync());

在需要验证的任何后续请求的 header 中添加该令牌:授权:Bearer {acces_token_value}

client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", ApiToken.ToString());
