Quick Start

Prerequisites:

Download the module:

go get -u github.com/hewenyu/zero-contrib/zrpc/registry/nacos

fix config

Addr: nacos-cs.ops.svc.cluster.local
Port: 8848
Group: DEFAULT_GROUP
DataID: demo-api
ExtDataIDs:
  - mysql
  - auth
NamespaceID: demo

For example:

Service

• main.go

import _ "github.com/hewenyu/zero-contrib/zrpc/registry/nacos"

func main() {
flag.Parse()

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

server := zrpc.MustNewServer(c.RpcServerConf, func (grpcServer *grpc.Server) {

})
// register service to nacos
sc := []constant.ServerConfig{
*constant.NewServerConfig("192.168.100.15", 8848),
}

cc := &constant.ClientConfig{
NamespaceId:         "public",
TimeoutMs:           5000,
NotLoadCacheAtStart: true,
LogDir:              "/tmp/nacos/log",
CacheDir:            "/tmp/nacos/cache",
RotateTime:          "1h",
MaxAge:              3,
LogLevel:            "debug",
}

opts := nacos.NewNacosConfig("nacos.rpc", c.ListenOn, sc, cc)
_ = nacos.RegisterService(opts)
server.Start()
}

Client

• main.go

import _ "github.com/hewenyu/zero-contrib/zrpc/registry/nacos"

• etc/*.yaml

# nacos://[user:passwd]@host/service?param=value'
Target: nacos://192.168.100.15:8848/nacos.rpc?namespaceid=public&timeout=5000s
