如何在.NET Core2.2中验证JWT承载令牌

using Microsoft.AspNetCore.Authentication.JwtBearer;
using Microsoft.IdentityModel.Tokens;

public void ConfigureServices(IServiceCollection services)
{
    // 添加JWT身份验证服务
    services.AddAuthentication(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"))
            };
        });

    // 其他服务配置...
}

public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
    // 其他中间件配置...

    // 启用身份验证中间件
    app.UseAuthentication();

    // 其他配置...
}

[Authorize]
public class MyController : Controller
{
    // 控制器方法...
}
