Golang gRPC 和 gRPC-gateway 结合使用

一、安装

go get -u github.com/grpc-ecosystem/grpc-gateway/protoc-gen-grpc-gateway
go get -u github.com/grpc-ecosystem/grpc-gateway/protoc-gen-swagger
go get -u github.com/golang/protobuf/protoc-gen-go

二、proto 文件

syntax = "proto3";
package gateway;

import "google/api/annotations.proto";

message StringMessage {
    string value = 1;
}

service Gateway {
   rpc Echo(StringMessage) returns (StringMessage) {
       option (google.api.http) = {
           post: "/v1/example/echo"
           body: "*"
       };
   }
}
