docker-compose服务：无法从主机获取配置：/。well-known / openid-configuration

Question

我在容器中运行了两个ASP.NET Core服务。一个运行IdentityServer4，另一个运行受IdentityServer保护的API。

使用快速入门中提供的示例代码，我能够通过客户端凭据检索访问令牌，但是，当我尝试使用该令牌调用受保护的API时，我在HTTP响应中收到500个内部服务器错误，以及API中的以下错误：

Connection id "0HLMS3H54RQK4", Request id "0HLMS3H54RQK4:00000001": An unhandled exception was thrown by the application. app_service | System.InvalidOperationException: IDX20803: Unable to obtain configuration from: 'http://localhost:5000/.well-known/openid-configuration'. ---> System.IO.IOException: IDX20804: Unable to retrieve document from: 'http://localhost:5000/.well-known/openid-configuration'. ---> System.Net.Http.HttpRequestException: Cannot assign requested address ---> System.Net.Sockets.SocketException: Cannot assign requested address

我的API设置有以下身份验证设置：

    public void ConfigureServices(IServiceCollection services)
    {
        IdentityModelEventSource.ShowPII = true;

        services.AddMvcCore(config => config.Filters.Add(typeof(HttpGlobalExceptionFilter)))
            .AddAuthorization()
            .AddNewtonsoftJson();

        services.AddAuthentication(options => {
            options.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
            options.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
        }).AddJwtBearer(options => 
            {
                options.Authority = "http://localhost:5000";
                options.RequireHttpsMetadata = false;
                options.Audience = "api1";
                // options.Configuration = new OpenIdConnectConfiguration();
            });
    }

如果将options.Configuration = new OpenIdConnectConfiguration();添加到配置中，并重复HTTP调用，我将收到401未经授权的HTTP响应，以及来自API的以下错误：

我的docker-compose.yml：

version: "3.7"

services:
  identityService:
    container_name: identity_service
    image: microsoft/dotnet:3.0-sdk
    tty: true
    ports:
      - 5000:80
    volumes:
      - ./services/IdentityService:/app
    working_dir: /app
    command: dotnet watch run

  appService:
    container_name: app_service
    depends_on:
      - identityService
    image: microsoft/dotnet:3.0-sdk
    ports:
      - 5001:80
    volumes:
      - ./services/AppService:/app
    working_dir: /app/AppService.Application
    command: dotnet watch run

有人知道我在做什么错吗？
