“ InvalidOperationException：IDX20803：无法从以下位置获取配置：[[PII被隐藏]'”

问题描述

我已经在Docker上部署了API和客户端应用程序，但是在我生命中，Web应用程序无法调用该API，因此我一直遇到异常。

I've deployed my API and Client app on Docker, but for the life of me, the web app cannot call the API, I keep getting an exception.

我添加了

IdentityModelEventSource.ShowPII = true;

例外：

System.InvalidOperationException: IDX20803: Unable to obtain configuration from: '[PII is hidden]'.
at Microsoft.IdentityModel.Protocols.ConfigurationManager`1.GetConfigurationAsync(CancellationToken cancel)
at Microsoft.AspNetCore.Authentication.JwtBearer.JwtBearerHandler.HandleAuthenticateAsync()
at Microsoft.AspNetCore.Authentication.JwtBearer.JwtBearerHandler.HandleAuthenticateAsync()
at Microsoft.AspNetCore.Authentication.AuthenticationHandler`1.AuthenticateAsync()
at Microsoft.AspNetCore.Authentication.AuthenticationService.AuthenticateAsync(HttpContext context, String scheme)
at IdentityServer4.AccessTokenValidation.IdentityServerAuthenticationHandler.HandleAuthenticateAsync()
at Microsoft.AspNetCore.Authentication.AuthenticationHandler`1.AuthenticateAsync()
at Microsoft.AspNetCore.Authentication.AuthenticationService.AuthenticateAsync(HttpContext context, String scheme)
at Microsoft.AspNetCore.Authentication.AuthenticationMiddleware.Invoke(HttpContext context)
at Microsoft.AspNetCore.StaticFiles.StaticFileMiddleware.Invoke(HttpContext context)
at Microsoft.AspNetCore.Cors.Infrastructure.CorsMiddleware.InvokeCore(HttpContext context)
at Microsoft.AspNetCore.Diagnostics.DeveloperExceptionPageMiddleware.Invoke(HttpContext context)

推荐答案

我们需要启用对PII日志的查看，以便我们可以查看有关该错误的更多详细信息：
在ConfigureServices（）中将以下行添加到Startup.cs

We need to enable viewing of PII logs so we can see more details about the error:Add the following line in ConfigureServices() to Startup.cs

public void ConfigureServices(IServiceCollection services)
{
    IdentityModelEventSource.ShowPII = true; //Add this line
    ....
