Hi, all. Recently, I do some research about RPC by using oslo-messaging. I write some demo code about RPC server and RPC client by following here [1]. And the demo codes locate here[2]. I think there is something wrong about these codes. The server code doesn't print response message when I run both the server code and the client code. And my oslo message version is oslo.messaging==4.6.1. Could someone give me some advice about that? Thanks a lot. ;-) [1].https://docs.openstack.org/developer/oslo.messaging/server.html https://docs.openstack.org/developer/oslo.messaging/client.html [2].http://paste.openstack.org/show/613472/ -------------- next part -------------- An HTML attachment was scrubbed...
