2. go使用grpc负载均衡

grpc-consul-resolver地址

3. 关于serverconfig

官方文档

4. go的grpc测试

package main
import (
    "OldPackageTest/grpclb_test/proto"
    "context"
    "fmt"
    "log"
    _ "github.com/mbobakov/grpc-consul-resolver" // It's important
    "google.golang.org/grpc"
)
func main() {
    conn, err := grpc.Dial(
        "consul://192.168.1.103:8500/user-srv?wait=14s&tag=srv",
        grpc.WithInsecure(),
        grpc.WithDefaultServiceConfig(`{"loadBalancingPolicy": "round_robin"}`),
    )
    if err != nil {
        log.Fatal(err)
    }
    defer conn.Close()
    for i := 0; i<10; i++{
        userSrvClient := proto.NewUserClient(conn)
        rsp, err := userSrvClient.GetUserList(context.Background(), &proto.PageInfo{
            Pn:    1,
            PSize: 2,
        })
        if err != nil {
            panic(err)
        }
        for index, data := range rsp.Data{
            fmt.Println(index, data)
        }
    }
