golang下使用grpc的一个简单例子

grpc

Golang grpc以及grpc-gateway的简单使用

编译proto

• 安装ProtocolBuffers以及gate-gateway，可以查找网站相关资料
• 编译google.api

cd protos
protoc --go_out=plugins=grpc:"." "google/api/*.proto"

• 编译*.proto

cd protos
protoc --go_out=plugins=grpc:"." ./*.proto

• 编译*.proto.gw.go

cd protos
protoc --grpc-gateway_out=logtostderr=true:"." "*.proto"

配置使用

• 拷贝conf/conf.toml.exmpale为conf/conf.toml，并配置数据库信息
• 执行服务端程序：go run server.go
• 执行客户端程序：go run client.go
• 执行gateway程序: go run gateway.go
