在.Net 5下使用HTTPS调用gRPC服务时发生证书错误：不可信
我正在尝试用HTTPS连接我的gRPC客户端和服务，它们都在本地Windows 10计算机上的.Net 5下运行。现在我收到此证书错误，不确定如何修复：在.Net 5下使用HTTPS调用gRPC服务时发生证书错误：不可信,https,grpc,.net-5,Https,Grpc,.net 5,我正在尝试用HTTPS连接我的gRPC客户端和服务，它们都在本地Windows 10计算机上的.Net 5下运行。现在我收到此证书错误，不确定如何修复： Status(StatusCode=\"Internal\", Detail=\"Error starting gRPC call.

但是，我注意到，我的商店中存在的证书是“IIS Express开发证书”，而不是“ASP.NET核心HTTPS开发证书”。那有关系吗？如果是，如何安装正确的证书？如果没有，我还缺少什么？如果有人感兴趣-在我的情况下，这是因为在我当前的Windows构建级别下，IIS不支持gRPC托管。在我等待MS完成解决方案时，我只是在gRPC客户端添加了以下内容：
var httpHandler = new HttpClientHandler();
httpHandler.ServerCertificateCustomValidationCallback = HttpClientHandler.DangerousAcceptAnyServerCertificateValidator;
var channel = GrpcChannel.ForAddress(ServerAddress, new GrpcChannelOptions { HttpHandler = httpHandler });
