运行代码出现下面的错误
4.文件目录结构：
5.下面我测试的helloworld代码,运行报错:
(1)sever.go
package main
import (
"context"
"fmt"
"github.com/micro/go-micro"
helloworld "gocode/basic-code/go-high/微服务/go-micro/go-Micro-helloworld/proto"
)
type HW struct {
}
func (g*HW)Hello(ctx context.Context,req*helloworld.HelloRequest,rsp *helloworld.HelloResponse)error{
rsp.Greeting="nihao:"+req.Name
return nil
}
func main(){
service:=micro.NewService(micro.Name("HelloWorld"),
micro.Version("1.0"),
micro.Metadata(map[string]string{"type":"helloworld"}))
service.Init()
helloworld.RegisterHelloWorldHandler(service.Server(),new(HW))
if err:=service.Run();err!=nil{
fmt.Println(err)//运行服务
}
}
(2)Client.go
package main
import (
"context"
"fmt"
"github.com/micro/go-micro"
helloworld "gocode/basic-code/go-high/微服务/go-micro/go-Micro-helloworld/proto"
)
func main(){
service:=micro.NewService(micro.Name("HelloWorld"),
micro.Version("1.0"),
micro.Metadata(map[string]string{"type":"helloworld"}))
service.Init()
greeter:=helloworld.NewHelloWorldService("HelloWorld",service.Client())
rep,err:=greeter.Hello(context.TODO(),&helloworld.HelloRequest{Name:"haha "})
if err!=nil{
fmt.Println(err)
}
fmt.Println(rep.Greeting)
}
(3)proto下的helloworld.proto
syntax="proto3";
service HelloWorld{
rpc Hello(HelloRequest) returns(HelloResponse){}
}
message HelloRequest{
string name=1;
}
message HelloResponse{
string greeting=2;
}
然后根据上面的自动生成相关代码
6.运行报错
