如何在 Asp net Core 2 中获取 Firebase IssuerSigningKey

Question

我正在开发使用 Firebase 进行身份验证的移动应用程序，但我无法在 asp net core 2 应用程序上验证来自 Firebase 的 JWT，我遇到的问题是获取 IssuerSigningKey，这是我在 asp 网络核心启动类中的代码示例。从Firebase文档中，他们说我应该从 https://www.googleapis.com/robot/v1/metadata/x509/[e-mail] 那里获得证书。我无法从那里继续

 services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
   .AddJwtBearer(options =>
   {
       options.TokenValidationParameters = new TokenValidationParameters
       {
           ValidateIssuer = true,
           ValidateAudience = true,
           ValidateLifetime = true,
           ValidateIssuerSigningKey = true,
           ValidIssuer = Configuration["Jwt:Issuer"],
           ValidAudience = Configuration["Jwt:aud"],
           IssuerSigningKey = 
       };
   });

我终于从这个网站上找到了答案 https://blog.markvincze.com/secure-an-asp-net-core-api-with-firebase/我需要添加的只是选项。权限 = 配置["JWT：颁发者"];并删除颁发者签名密钥

 services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
 .AddJwtBearer(options =>
 {
     options.Authority = Configuration["Jwt:Issuer"];
   options.TokenValidationParameters = new TokenValidationParameters
   {
       ValidateIssuer = true,
       ValidateAudience = true,
       ValidateLifetime = true,
       ValidateIssuerSigningKey = true,
       ValidIssuer = Configuration["Jwt:Issuer"],
       ValidAudience = Configuration["Jwt:aud"],
   };
});
