ASP.NET Core使用JWT认证授权的方法(3)

namespace JWTS.Controllers
{
  [Route("api/[controller]")]
  [ApiController]
  public class AuthenticationController : ControllerBase
  {
    #region 构造函数
    private ILogger<AuthenticationController> _logger;
    private IJWTService _iJWTService;
    private readonly IConfiguration _iConfiguration;
    public AuthenticationController(ILogger<AuthenticationController> logger,
      IConfiguration configuration
      , IJWTService service)
    {
      _logger = logger;
      _iConfiguration = configuration;
      _iJWTService = service;
    }
    #endregion

/// <summary>
    /// 实际场景使用Post方法
    ///http://localhost:5000/api/Authentication/Login?name=william&password=123123

/// </summary>
    /// <param></param>
    /// <param></param>
    /// <returns></returns>
    [Route("Login")]
    [HttpGet]
    public IActionResult Login(string name, string password)
    {
      //这里应该是需要去连接数据库做数据校验，为了方便所有用户名和密码写死了
      if ("william".Equals(name) && "123123".Equals(password))//应该数据库
      {
        var role = "Administrator";//可以从数据库获取角色
        string token = this._iJWTService.GetToken(name, role);
        return new JsonResult(new
        {
          result = true,
          token
        });
      }

return Unauthorized("Not Register!!!");
    }
  }
}

2、资源中心API:使用从认证服务中心获取的Token，去访问资源，资源中心对用户信息以及Token进行鉴权操作，认证失败返回401

1、资源中心添加Nuget包（Microsoft.AspNetCore.Authentication.JwtBearer）

2、添加Authentication服务，添加JwtBearer，通过Configuration获取TokenParameter对象

using System;
using System.Text;
using API.Core.Models;
using Microsoft.AspNetCore.Authentication.JwtBearer;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;
using Microsoft.IdentityModel.Tokens;

namespace API.Core
{
  public class Startup
  {
    private TokenParameter _tokenParameter;
    public IConfiguration Configuration { get; }
    public Startup(IConfiguration configuration)
    {
      Configuration = configuration;
      _tokenParameter = configuration.GetSection("TokenParameter").Get<TokenParameter>()??throw new ArgumentNullException(nameof(_tokenParameter));
    }
