Identity Server 4部署到Azure AppService时找不到证书

Question

我有一个asp.net核心托管的blazor wasm应用程序。我使用默认模板通过Identity Server 4进行身份验证。在发布模式下对它进行本地测试时，它可以按预期工作。但是当我部署到Azure AppService时，出现此异常：

    2020-05-08 07:45:50.244 +00:00 [ERR] An unhandled exception has occurred while executing the request.

   at Microsoft.AspNetCore.Diagnostics.ExceptionHandlerMiddleware.<Invoke>g__Awaited|6_0(ExceptionHandlerMiddleware middleware, HttpContext context, Task task)

在我的应用程序设置中，我具有此配置：

  "IdentityServer": {
    "Clients": {
      "ApplySupportTool.Client": {
        "Profile": "IdentityServerSPA"
      }
    },
    "Key": {
      "Type": "File",
      "FilePath": "applysupporttool.pfx",
      "Password": "{Password}"
    }
  }

并且在我的Startup.cs中，我在ConfigureServices方法中具有此功能：

        services.AddIdentityServer()
                .AddApiAuthorization<ApplicationUser, SupportToolContext>();

        services.AddAuthentication()
            .AddIdentityServerJwt();

并且这在配置方法中：

        app.UseIdentityServer();
        app.UseAuthentication();
        app.UseAuthorization();

我根据asp.net核心blazor wasm模板进行了单独验证。

密码已正确填入Azure本身。 Azure与我的系统有什么不同？

Answer 1

我在AWS ElasticBeanstalk基础架构上设置IdentityServer时遇到了这个问题。我发现EC2实例上的应用程序池未将“加载用户配置文件”设置为true。设置后，权限模型将更改并允许该过程加载到证书中。您可以通过应用程序池详细信息上的IIS管理UI启用，或使用下面的脚本版本。

Import-Module WebAdministration
Set-ItemProperty "IIS:\AppPools\DefaultAppPool" -Name "processModel.loadUserProfile" -Value "True"
