我已经在.NET中成功地制作了一个Grpc服务器和客户端。我正在尝试从Python重新创建客户端。在.NET中，我必须创建这些channelOptions，以避免返回SSL错误。我无法在Python中复制这些选项。我已经尝试使用channel = grpc.insecure_channel('127.0.0.1:5001')并收到相同的状态代码，它是不可用的。尽管存在该错误，但我可以正常运行.NET客户端。
我使用$ python -m grpc_tools.protoc -I../../protos --python_out=. --pyi_out=. --grpc_python_out=. ../../protos/route_guide.protopb2.py从.NET应用程序中的proto文件填充www.example.com和pb2_grpc.py文件。我是否需要使用指定Python客户端的语法构建.proto文件？
//.NET

var handler = new HttpClientHandler
{
    ServerCertificateCustomValidationCallback = HttpClientHandler.DangerousAcceptAnyServerCertificateValidator
};

var channelOptions = new GrpcChannelOptions
{
    HttpHandler = handler
};

var channel = GrpcChannel.ForAddress("https://127.0.0.1:5001",channelOptions);

//Python

options = [('grpc.ssl_target_name_override', '127.0.0.1')]
creds = grpc.ssl_channel_credentials()
channel = grpc.secure_channel("127.0.0.1:5001", creds, options)

//错误
