FAQ:

1. API，Web和SRV服务有什么区别？

2. Micro是否支持gRPC？

hhstore commented 5 years ago

go-micro 支持 rest API:

go-micro 集成各种插件服务:

1. 集成 swagger:


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

2. 问题跟踪系统:

go-micro 官方文档摘要:

ref: 参考实践:

0. 项目脚手架: micro

go get -u github.com/micro/micro

#
brew install protobuf

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

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

使用示例:

# 创建:
micro new github.com/micro/example

# 编译pb:
protoc --proto_path=. --micro_out=. --go_out=. proto/example/example.proto

# 运行:
go run main.go

cli 工具支持命令:

1. 安装指南:


go get github.com/micro/go-micro
go get github.com/micro/micro

# Demo:
go get github.com/micro/examples/greeter/srv && srv

2. 配合 grpc-gateway 项目:

3. 服务定义:

go micro:

1. 准备环境: consul 依赖服务注册


docker-compose -f devops-consul.yml up -d

2. 创建项目:


cd $GOPATH

# 创建一个demo项目:
micro new micro_demo

# 创建成功有提示信息: 告诉你先生成 protobuf文件:
cd $GOPATH/src/micro_demo

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

3. 启动项目:


cd GOPATH/src/micro_demo

(py27-base) ζ go run main.go

从0到1创建一个完整的micro项目:

1. 创建git项目:

git clone git@gitlab.com:ceres-mirror/exchange-trade-proxy4.git

2. 安装 micro 环境:

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

# 创建API依赖:
go get -t github.com:micro/go-api

3. 使用micro脚手架初始化工程:


# exchange:
micro new --type srv --alias exchange --namespace "com.ceres.trade.proxy" gitlab.com/ceres-mirror/exchange-trade-proxy4/server/exchange/srv
micro new --type web --alias exchange --namespace "com.ceres.trade.proxy" gitlab.com/ceres-mirror/exchange-trade-proxy4/server/exchange/web
micro new --type api --alias exchange --namespace "com.ceres.trade.proxy" gitlab.com/ceres-mirror/exchange-trade-proxy4/server/exchange/api
micro new --type fnc --alias exchange --namespace "com.ceres.trade.proxy" gitlab.com/ceres-mirror/exchange-trade-proxy4/server/exchange/fnc

# trade:
micro new --type srv --alias trade --namespace "com.ceres.trade.proxy" gitlab.com/ceres-mirror/exchange-trade-proxy4/server/trade/srv
micro new --type web --alias trade --namespace "com.ceres.trade.proxy" gitlab.com/ceres-mirror/exchange-trade-proxy4/server/trade/web
micro new --type api --alias trade --namespace "com.ceres.trade.proxy"  gitlab.com/ceres-mirror/exchange-trade-proxy4/server/trade/api

# order:
micro new --type srv --alias order --namespace "com.ceres.trade.proxy" gitlab.com/ceres-mirror/exchange-trade-proxy4/server/order/srv
micro new --type web --alias order --namespace "com.ceres.trade.proxy" gitlab.com/ceres-mirror/exchange-trade-proxy4/server/order/web
micro new --type api --alias order --namespace "com.ceres.trade.proxy" gitlab.com/ceres-mirror/exchange-trade-proxy4/server/order/api

4. 编译服务:

cd ~/src/gitlab.com/ceres-mirror/exchange-trade-proxy4/server/trade/api
protoc --proto_path=. --go_out=. --micro_out=. proto/example/example.proto

5. 预先启动 consul:

6. 启动服务:

# 服务1:
./exchange-srv
# 服务2:
./exchange-web

# 启动 :8082 端口访问web端
micro web  

# 启动:
micro api

7. 调用服务:
