warden.NewClient 初始化后 please config a default HOST错误 about kratos

[noahzaozao]

范例中的 resolver.Register(discovery.Builder())方法，在Builder方法内,
discovery.go 116行处调用New( nil)，由于传入了nil的*Config，
导致在discovery.go 141行fixConfig(c) 方法内
discovery.go 94行报出错误 NOTE: please config a default HOST

package dao

import (
	"context"

	"github.com/bilibili/kratos/pkg/net/rpc/warden"

	"google.golang.org/grpc"
)

// AppID unique app id for service discovery
const AppID = "your app id"

// NewClient new member grpc client
func NewClient(cfg *warden.ClientConfig, opts ...grpc.DialOption) (DemoClient, error) {
	client := warden.NewClient(cfg, opts...)
	conn, err := client.Dial(context.Background(), "discovery://default/"+AppID)
	if err != nil {
		return nil, err
	}
	// 注意替换这里：
	// NewDemoClient方法是在"api"目录下代码生成的
	// 对应proto文件内自定义的service名字，请使用正确方法名替换
	return NewDemoClient(conn), nil
}

测试代码引用自 warden-quickstart.md 91-117行

已解决，在client := warden.NewClient(cfg, opts...)之前加如下代码，问题解决

conf := &naming.Config{
		Nodes: []string{"127.0.0.1:7171"},
		Zone:  "sh1",
		Env:   "test",
	}
	dis := naming.New(conf)
	dis.Build(AppID)
