README

Quick Start

Prerequisites:

Download the module:

go get -u github.com/zeromicro/zero-contrib/zrpc/registry/consul

For example:

修改RPC服务的代码

• etc/*.yaml

Consul:
  Host: 127.0.0.1:8500 # consul endpoint
  Token: 'f0512db6-76d6-f25e-f344-a98cc3484d42' # consul ACL token (optional)
  Key: add.rpc # service name registered to Consul
  Meta:
    Protocol: grpc
  Tag:
    - tag
    - rpc

• internal/config/config.go

type Config struct {
	zrpc.RpcServerConf
	Consul consul.Conf
}

• main.go

import _ "github.com/zeromicro/zero-contrib/zrpc/registry/consul"

func main() {
	flag.Parse()

	var c config.Config
	conf.MustLoad(*configFile, &c)

	server := zrpc.MustNewServer(c.RpcServerConf, func(grpcServer *grpc.Server) {
	
	})
 	// register service to consul
	_ = consul.RegisterService(c.ListenOn, c.Consul)

	server.Start()
}

修改API服务里的代码

• main.go

import _ "github.com/zeromicro/zero-contrib/zrpc/registry/consul"

• etc/*.yaml

# consul://[user:passwd]@host/service?param=value'
# format like this
Add:
  Target: consul://127.0.0.1:8500/add.rpc?wait=14s
Check:
  Target: consul://127.0.0.1:8500/check.rpc?wait=14s
  
# ACL token support
Add:
  Target: consul://127.0.0.1:8500/add.rpc?wait=14s&token=f0512db6-76d6-f25e-f344-a98cc3484d42
Check:
  Target: consul://127.0.0.1:8500/check.rpc?wait=14s&token=f0512db6-76d6-f25e-f344-a98cc3484d42
