在rpc服务中添加配置
导入包：
go get -u github.com/zeromicro/zero-contrib/zrpc/registry/consul在rpc服务中添加配置：
进入项目代码 /gopath/gonivinck/code/go-zero-mall/
修改 service/user/rpc/internal/configrpc/internal/config 文件
引入 Consul config 配置项
vim /usr/src/code/go-zero-mall/service/user/rpc/internal/config/config.go
package config
import (
"github.com/zeromicro/go-zero/core/logx"
"github.com/zeromicro/go-zero/core/stores/cache"
"github.com/zeromicro/go-zero/zrpc"
"github.com/zeromicro/zero-contrib/zrpc/registry/consul"
)
type Config struct {
zrpc.RpcServerConf
Mysql struct {
DataSource string
}
CacheRedis cache.CacheConf
Salt string
//引入consul配置
Consul consul.Conf
Log logx.LogConf
}user.yml 文件
vim /usr/src/code/go-zero-mall/service/user/rpc/etc/user.yml
Name: user.rpc

Salt: HWVOFkGgPTryzICwd7qnJaZR9KQ2i8xe修改 user.go,将 rpc注册到consul
vim /usr/src/code/go-zero-mall/service/user/rpc/user.go
package main
import (
"flag"
"fmt"
"github.com/zeromicro/zero-contrib/zrpc/registry/consul"

"google.golang.org/grpc/reflection"
)
var configFile = flag.String("f", "etc/user.yaml", "the config file")
func main() {
flag.Parse()
var c config.Config
conf.MustLoad(*configFile, &c)
ctx := svc.NewServiceContext(c)
svr := server.NewUserServer(ctx)
s := zrpc.MustNewServer(c.RpcServerConf, func(grpcServer *grpc.Server) {
user.RegisterUserServer(grpcServer, svr)
if c.Mode == service.DevMode || c.Mode == service.TestMode {
reflection.Register(grpcServer)
}
})
//将 rpc注册到consul
_= consul.RegisterService(c.ListenOn,c.Consul)
defer s.Stop()
fmt.Printf("Starting rpc server at %s...\n", c.ListenOn)
s.Start()
}rpc的发现
在api服务中添加配置：
修改 api/internal/config config.go 文件
vim /usr/src/code/go-zero-mall/service/user/api/internal/config/config.go
package config
import (
"github.com/zeromicro/go-zero/core/logx"
"github.com/zeromicro/go-zero/rest"
"github.com/zeromicro/go-zero/zrpc"
"github.com/zeromicro/zero-contrib/zrpc/registry/consul"
)
type Config struct {
rest.RestConf
Auth struct {
AccessSecret string
AccessExpire int64
}
UserRpc zrpc.RpcClientConf
Consul consul.Conf
Log logx.LogConf
}修改api/etc/user.yam 文件
Name: User

Consul:

Key: user.rpc
# Etcd:
# Hosts:
# - etcd:2379
# Key: user.rpc修改 user.yml
添加一个UserRpc配置，去掉官方自带的Etcd配置
vim /usr/src/code/go-zero-mall/service/user/api/etc/user.yml
Name: User
Host: 0.0.0.0
Port: 8000

Key: user.rpc
# Etcd:
# Hosts:
# - etcd:2379
# Key: user.rpc修改api/user.go
vim /usr/src/code/go-zero-mall/service/user/api/user.go
package main
import (
"flag"
"fmt"
"mall/service/user/api/internal/config"
"mall/service/user/api/internal/handler"
"mall/service/user/api/internal/svc"
"github.com/zeromicro/go-zero/core/conf"
"github.com/zeromicro/go-zero/rest"
_ "github.com/zeromicro/zero-contrib/zrpc/registry/consul"
)
var configFile = flag.String("f", "etc/user.yaml", "the config file")
func main() {
flag.Parse()
var c config.Config
conf.MustLoad(*configFile, &c)
ctx := svc.NewServiceContext(c)
server := rest.MustNewServer(c.RestConf)
defer server.Stop()
handler.RegisterHandlers(server, ctx)
fmt.Printf("Starting server at %s:%d...\n", c.Host, c.Port)
server.Start()
}启动rpc服务和api服务
可以看到rpc服务已经被注册和发现了
