如何从.Net核心[Authorize]方法返回auth令牌

public void ConfigureServices(IServiceCollection services)
{
    // 添加身份验证服务
    services.AddAuthentication(options =>
    {
        options.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
        options.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
    })
    .AddJwtBearer(options =>
    {
        options.TokenValidationParameters = new TokenValidationParameters
        {
            ValidateIssuer = true,
            ValidateAudience = true,
            ValidateLifetime = true,
            ValidateIssuerSigningKey = true,
            ValidIssuer = "your-issuer",
            ValidAudience = "your-audience",
            IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes("your-secret-key"))
        };
    });

    // 添加其他服务配置
    // ...
}

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
    // 启用身份验证中间件
    app.UseAuthentication();

    // 添加其他中间件配置
    // ...
}

[ApiController]
[Route("api/[controller]")]
public class YourController : ControllerBase
{
    [Authorize]
    [HttpGet]
    public IActionResult Get()
    {
        // 处理请求并返回数据
    }
}
