[英]ASP.Net Core 3.0 JWT Bearer Token No SecurityTokenValidator available
我使用 ASP.Net Core 3.0 API 和 EntityFramework Core 作為 UserStorage。 啟動.cs:
public void ConfigureServices(IServiceCollection services)
{
using Microsoft.AspNetCore.Authentication.JwtBearer;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Identity;
using Microsoft.AspNetCore.SpaServices.AngularCli;
using Microsoft.EntityFrameworkCore;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;
using Microsoft.IdentityModel.Tokens;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
.
.
.
//Add Identity Provider with EntityFramework
services.AddIdentity<User, IdentityRole>()
.AddEntityFrameworkStores<ApplicationDBContext>()
.AddDefaultTokenProviders();
//Initialize EntityFramework
services.AddDbContext<ApplicationDBContext>(options => options.UseSqlite(Configuration.GetConnectionString("localDB")));
//Initialize JWT Authentication
services.AddAuthentication(options => {
options.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
options.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
}).AddJwtBearer(jwtBearerOptions =>
{
jwtBearerOptions.TokenValidationParameters = new TokenValidationParameters()
{
ValidateIssuer = true,
ValidateAudience = true,
ValidateLifetime = true,
ValidateIssuerSigningKey = true,
ValidIssuer = "http://localhost:44352",
ValidAudience = "http://localhost:44352",
IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(Configuration.GetSection("Secrets")["jwt"]))
};
}
);
services.AddMvc(options => options.EnableEndpointRouting = false)
.AddNewtonsoftJson();
// In production, the Angular files will be served from this directory
services.AddSpaStaticFiles(configuration =>
{
configuration.RootPath = "ClientApp/dist";
});
}
.
.
.
app.UseHttpsRedirection();
app.UseStaticFiles();
app.UseSpaStaticFiles();
//Enable Authentication
app.UseAuthentication();
app.UseAuthorization();
.
.
.
app.UseMvc(routes =>
{
routes.MapRoute(
name: "default",
template: "{controller}/{action=Index}/{id?}");
});
.
.
.
這是我發出 JWT 令牌的代碼:
public async Task<IActionResult> Login()
{
using (var reader = new StreamReader(Request.Body))
{
var body = await reader.ReadToEndAsync();
var cred = JsonConvert.DeserializeObject<Credentials>(body);
var result = (await userService.LoginUser(cred.userName, cred.password));
if (result == 200)
{
var secretKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(configuration.GetSection("Secrets")["jwt"]));
var signinCredentials = new SigningCredentials(secretKey, SecurityAlgorithms.HmacSha256Signature);
var roles = await userService.GetRoleFromUsername(cred.userName);
var rolesString = JsonConvert.SerializeObject(roles);
var tokeOptions = new JwtSecurityToken(
issuer: "http://localhost:44352",
audience: "http://localhost:44352",
claims: new List<Claim>(new List<Claim> {
new Claim("userName",cred.userName),
new Claim("roles", rolesString)
}),
expires: DateTime.Now.AddHours(1),
signingCredentials: signinCredentials
);
這是我使用授權的 API 調用:
[Route("api/videos/add")]
[Authorize(Roles = "Admin")]
[HttpPost]
public async Task<IActionResult> AddVideo()
{
using (var reader = new StreamReader(Request.Body))
{
var body = await reader.ReadToEndAsync();
var video = JsonConvert.DeserializeObject<Video>(body);
await videoService.AddVideo(video);
return Ok();
}
}
我的 NuGet 包是:
我遇到的問題是,如果我調用該 API 部分,則會收到錯誤消息:
信息:承載未通過身份驗證。 失敗消息:沒有 SecurityTokenValidator 可用於令牌:
任何幫助將不勝感激,因為我找不到錯誤
如果要將角色添加為聲明,請嘗試使用ClaimTypes.Role
而不是roles
。
var tokeOptions = new JwtSecurityToken(
issuer: "http://localhost:44352",
audience: "http://localhost:44352",
claims: new List<Claim>(new List<Claim> {
new Claim("userName",cred.userName),
new Claim(ClaimTypes.Role, "Admin")
}),
expires: DateTime.Now.AddHours(1),
signingCredentials: signinCredentials
);
我是這樣處理這個問題的:
client.DefaultRequestHeaders.Add("Authorization", $"Bearer {token.Replace("\"", "")}");
不是最好的解決方案,但它奏效了。
