JWT Bearer ASP.Net Core 3.1 用户在服务器上为空

今天，我一直在尝试使用 Microsoft.AspNetCore.Authentication.JwtBearer 库将 JSON Web 令牌信息绑定到 HttpContext.User。

问题： 每次调用服务器时，我都可以使用 [Authorize] 属性进入函数，但 User 对象完全是空白的。很高兴知道每个用户是谁。

My decoded JWT on the client-side:

我的客户端函数调用服务器上的 [Authorize] C# 方法：

testAuth() {
    let token = localStorage.getItem("jwt");
    console.log(this.jwtHelper.decodeToken(token)); // Where I got the decoded JWT picture
    this.http.get(this.baseUrl + "Authentication/Test", {
      headers: new HttpHeaders({
        "Content-Type": "application/json",
        "Authentication": "Bearer " + token
      })
    }).subscribe(response => {
      console.log(response); // never happens
    }, err => {
      console.log(err); // always happens because User.Identity is null
    });
  }

服务器方法中 User.Identity 始终为空，但我们可以通过 [Authorize] 属性：

[HttpGet]
[Authorize]
public IActionResult Test()
{
    // User.Identity is always blank, so a 500 error is thrown because Name == null
    return Ok(HttpContext.User.Identity.Name);
}

中间件管道：Startup.cs 中的ConfigureServices()：

services.AddControllers();

            // Enable CORS (cross origin requests) so other sites can send requests to the auth API
            services.AddCors();

            // JWT
            // Use JSON Web Tokens for auth
            services.AddAuthentication(opt => {
                opt.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
                opt.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
            })
            .AddJwtBearer(x =>
            {
                x.RequireHttpsMetadata = false;
                x.SaveToken = true;
                x.TokenValidationParameters = new TokenValidationParameters
                {
                    ValidateAudience = true,
                    ValidateIssuerSigningKey = true,
                    ValidateLifetime = false,
                    IssuerSigningKey = new SymmetricSecurityKey(System.Text.Encoding.UTF8.GetBytes(Configuration.GetValue<string>("JwtInfo:SecretKey"))),
                    ValidIssuer = Configuration.GetValue<string>("JwtInfo:ServerAddress", "http://localhost:44351/"), // Address that this project is running on
                    ValidAudience = Configuration.GetValue<string>("JwtInfo:ValidRecipients", "http://localhost:44364/") // Addresses of projects that are allowed to access this API
                };
            });

Startup.cs 中的配置（）：

app.UseHttpsRedirection();

            app.UseRouting();

            // Allow CORS (cross origin requests)
            // This must come before routing, authentication, and endpoints
            app.UseCors(option => option
                .AllowAnyOrigin()
                .AllowAnyMethod()
                .AllowAnyHeader());

            // Use JWT authentication
            app.UseAuthentication();
            app.UseAuthorization();

如何正确地将 JWT 声明绑定到用户的声明？

如果用户为空，我如何通过[授权]？

感谢您的帮助！

包含令牌的标头设置不正确。 它应该是：

"Authorization": "Bearer " + token

而不是“身份验证”：“承载”+令牌
