.net - IIS 日志失败 : Microsoft. AspNetCore.Server.Kestrel[13] JwtBearerOptions

Question

在 IIS 中运行已发布的 API 时，出现以下错误:

Hosting environment: Production
Content root path: C:\inetpub\My_API
Now listening on: http://127.0.0.1:44674
Application started. Press Ctrl+C to shut down.
fail: Microsoft.AspNetCore.Server.Kestrel[13]
      Connection id "0HM9MTIMQIFTF", Request id "0HM9MTIMQIFTF:00000001": An unhandled exception was thrown by the application.

在Startup.cs文件中，生成错误的行代码如下:

services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme).AddJwtBearer(options => 
options.TokenValidationParameters = new TokenValidationParameters
      {
          ValidateIssuer = false,
          ValidateAudience = false,
          //ValidateLifetime = false,
          ValidateIssuerSigningKey = true,
          //ValidIssuer = "https://locahost",
          //ValidAudience = "https://localhost",
          IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(Configuration["Key_Token"])),
                ClockSkew = TimeSpan.Zero
      });

在开发模式下执行 API 不会出现任何问题，身份验证也没有问题，但在生产模式下执行 API 时，服务器响应状态为 500。

如果有人能帮我解决这个问题。

谢谢你所做的一切。

祝一切顺利。

我已经找到了解决问题的方法。 发生错误的原因是在 Startup.cs 中找不到生成 JWT token 的 key 。在开发环境中，该 key 存储在 appLaunchSettings.json 文件中的项目环境变量中，但是当传递到生产环境时，在 appSettings.json< 中找不到该 key /em> 文件，因此在 StartUp.cs 中找不到该文件时会出现错误。 为了解决这个问题，我已将创建的变量保存在 appLaunchSettings.json 文件中 appSettings.json 文件中，现在一切正常。

谢谢。
