微服务框架—搭建 go-micro环境详解编程语言

//下载,不同的版本文件名称不一样,我们这里选择protoc-3.9.1-win64.zip 

protoc-3.9.1-win64.zip 

//解压到目标文件架,我们以e:/dev为例 

e:/dev/protoc-3.9.1-win64 

//添加e:/dev/protoc-3.9.1-win64/bin到环境变量path 

3.安装protoc-gen-micro插件

//这个插件主要作用是通过.proto文件生成适用于go-micro的代码 

go get -u -v github.com/micro/protoc-gen-micro 

4.安装 consul

//下载windows版本 

https://www.consul.io/downloads.html 

//解压到 

e:/dev/consul 

添加e:/dev/consul到环境变量path
使用如下指查看是否安装成功,如下所示安装成功

 consul 

Usage: consul [--version] [--help] command [ args ] 

Available commands are: 

 acl Interact with Consuls ACLs 

 agent Runs a Consul agent 

 catalog Interact with the catalog 

 config Interact with Consuls Centralized Configurations 

 connect Interact with Consul Connect 

 debug Records a debugging archive for operators 

5.创建微服务 hello world

//使用如下指令创建微服务 

 micro new techidea8.com/microapp/hello 

Creating service go.micro.srv.hello in E:/winlion/gopath/src/techidea8.com/microapp/hello 

├── main.go 

├── plugin.go 

├── handler 

│ └── hello.go 

├── subscriber 

│ └── hello.go 

├── proto/hello 

│ └── hello.proto 

├── Dockerfile 

├── Makefile 

├── README.md 

└── go.mod 


go get -u github.com/golang/protobuf/{proto,protoc-gen-go} 

go get -u github.com/micro/protoc-gen-micro 

compile the proto file hello.proto: 

cd E:/winlion/gopath/src/techidea8.com/microapp/hello 

protoc --proto_path=.:$GOPATH/src --go_out=. --micro_out=. proto/hello/hello.proto 

6.生成适配proto的golang代码

#切换到项目目录下 

 cd /d E:/winlion/gopath/src/techidea8.com/microapp/hello 

# 根据proto生成文件 

 protoc --proto_path=. --go_out=. --micro_out=. proto/hello/hello.proto 

# 启动应用 

 go run main.go

# 查看是否启动 

 micro list services 

go.micro.srv.hello 

topic:go.micro.srv.hello 

7.启动restful api接口支持支持

注意其中的 namespace参数,我们每一个微服务都属于一个命名空间,通过api暴露出来该命名空间后,满足go.micro.srv.*格式的微服务都可以访问。如go.micro.srv.hello可以通过如下格式访问

# 访问http://127.0.0.1:8080/hello/call 

 micro api --namespace=go.micro.srv
