在.net核心web api中使用OAUTH2 Cognito配置参数进行令牌验证

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

public void ConfigureServices(IServiceCollection services)
{
    // 添加身份验证服务
    services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
        .AddJwtBearer(options =>
        {
            options.Authority = "https://your-cognito-domain.auth.us-east-1.amazoncognito.com";
            options.Audience = "your-audience";
            options.TokenValidationParameters = new TokenValidationParameters
            {
                ValidateIssuer = true,
                ValidateAudience = true,
                ValidateLifetime = true,
                ValidateIssuerSigningKey = true,
                ValidIssuer = "https://your-cognito-domain.auth.us-east-1.amazoncognito.com",
                ValidAudience = "your-audience",
                IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes("your-signing-key"))
            };
        });

    // 其他服务配置...
}

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
    // 其他配置...

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

    // 其他配置...
}
