c# - IDX20803 : Unable to obtain configuration from: 'https://localhost/IdentityServer/Core/.well-known/openid-configuration'

Question

我们正在为 IdentityServer 使用 IdentityServer3.Membership 库。 token 验证在本地和 QA 机器中使用 HTTP 都可以正常工作。但是当我们配置为 HTTPS 时，就会出现以下错误。 步骤。

使用identityserver4.AccessTokenValidation库3.0.1验证Asp.net core 3.0应用程序中的 token 当我们在 IIS 中托管时出现错误。并使用自签名和 CA 证书 证书已添加到受信任的证书中。

解决了在启动-->配置中添加以下代码的问题

ServicePointManager.Expect100Continue = true;
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls
| SecurityProtocolType.Tls11
| SecurityProtocolType.Tls12
| SecurityProtocolType.Ssl3;
