我正在尝试在网络API上发出GET请求。我构建了客户端。问题似乎在于使用不记名令牌进行身份验证。我已经看过很多帖子但没什么用。
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;
}
}
}
如何使用令牌身份验证制作承载? 或者是其他一些我不能正确做到的事情?
谢谢!
答案 0 :(得分:1)
您需要使用以下http正文密钥值对向您的web api授权终端发送有效请求(例如&#34; username, password, client_id and grant_type=password
&#34;):await client.PostAsync("token", content);
。 (请务必遵循您的请求的内容类型标题)
用于该用途ApiToken = await JsonConvert.DeserializeObject<Token>(response.Content.ReadAsStringAsync());
如果授权成功,您将收到包含access_token的响应。您可以使用令牌对象反序列化为(client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", ApiToken.ToString());
在您需要进行身份验证的任何后续请求的标头中添加该令牌:授权:Bearer {acces_token_value}
