Asp.net mvc 无法从以下位置获取配置：'http://www.example.com:8080/openam/.well-已知/openid配置'

我正在使用Access Management OpenAM 6.5版和ASP.NET Core 2.1。 我创建了简单的mvc web应用程序。我添加了“谷歌”、“facebook”外部登录，以及“openam”作为外部登录。 但是我犯了以下错误

HttpRequestException: Response status code does not indicate success: 404 ().
System.Net.Http.HttpResponseMessage.EnsureSuccessStatusCode()

IOException: IDX20804: Unable to retrieve document from: 'http://www.example.com:8080/openam/.well-known/openid-configuration'.
Microsoft.IdentityModel.Protocols.HttpDocumentRetriever.GetDocumentAsync(string address, CancellationToken cancel)

InvalidOperationException: IDX20803: Unable to obtain configuration from: 'http://www.example.com:8080/openam/.well-known/openid-configuration'.
Microsoft.IdentityModel.Protocols.ConfigurationManager<T>.GetConfigurationAsync(CancellationToken cancel)

你需要使用

http://www.example.com:8080/openam/oauth2/.well-known/openid-configuration

而不是

http://www.example.com:8080/openam/.well-known/openid-configuration

请看

http://www.example.com:8080/openam/.well-known/openid-configuration
