How to create a channel from URL #164
Comments
I don't know any gRPC server or client implementation which supports serving requests with some path prefix. https://github.com/grpc/grpc/blob/master/doc/PROTOCOL-HTTP2.md
I think that it is better to find another way to distinguish environments. Is this server written by you or by someone else? |
Have it in c#, but after a little testing it seem not to do anything, I will get back when I know more. var channelOptionsLocal = new GrpcChannelOptions { MaxReceiveMessageSize = null }; // Remove MaxMessageSize limit
LocalManagerChannel = GrpcChannel.ForAddress(@"http://localhost:5000/backendDev", channelOptionsLocal); I have control of the server, so first thought would be to have a unique port for each environment. But I'm not sure how to create a channel to our azure service then, I tried with the IP from the URL, but then I get an connection lost exception. It's a https connection. Channel(host="backendDev.azure.com", port=443) Traceback (most recent call last):

Try this way: Channel(host="backendDev.azure.com", port=443, ssl=True)

Now I get an GRPCError grpclib.exceptions.GRPCError: (<Status.UNKNOWN: 2>, "Received :status = '426'", None) Tried https://grpclib.readthedocs.io/en/latest/errors.html#error-details but details is None |
The problem seems to be that the cloud service is running http 1.1 with UseGrpcWeb and only http 2 is supported. |
Maybe there is some kind of misconfiguration on the server-side or a bug like this: dotnet/aspnetcore#14139
|
The connection is not secure , hence the error. Is the service deployed as part of kube cluster in AKS. They would have used ingress to expose the service endpoint. Try to get the client certificate and try a secure channel creation. |
How do I create a channel where the host is an URL?
eg:
Channel(host="localhost/backendDev", port=5000)
The server is made in c# and runs in an windows service and the LaunchSettings look like this:
Running it with just localhost works fine, but I use backend to distinguish between prod, test and dev environments.
