golang project component grpc-gateway-yaml defines http rules and customizes gateway routing

YAML defines http rules and custom implementation of gateway routing Defining http rules in proto is always troublesome, because the proto file still defines messages, and the grpc interface is better. There is a better way to configure http rules. We can use yaml files to define http rules for the interface. At the same […]
