1. go操作nacos

  1. package main
  3. import (
  4.     "fmt"
  5.     "time"
  7.     "github.com/nacos-group/nacos-sdk-go/clients"
  8.     "github.com/nacos-group/nacos-sdk-go/common/constant"
  9.     "github.com/nacos-group/nacos-sdk-go/vo"
  10. )
  11. func main(){
  12.     sc := []constant.ServerConfig{
  13.         {
  14.             IpAddr: "192.168.1.103",
  15.             Port: 8848,
  16.         },
  17.     }
  19.     cc := constant.ClientConfig {
  20.         NamespaceId:         "c1872978-d51c-4188-a497-4e0cd20b97d5", // 如果需要支持多namespace，我们可以场景多个client,它们有不同的NamespaceId
  21.         TimeoutMs:           5000,
  22.         NotLoadCacheAtStart: true,
  23.         LogDir:              "tmp/nacos/log",
  24.         CacheDir:            "tmp/nacos/cache",
  25.         RotateTime:          "1h",

  27.         LogLevel:            "debug",
  28.     }
  30.     configClient, err := clients.CreateConfigClient(map[string]interface{}{
  31.         "serverConfigs": sc,
  32.         "clientConfig":  cc,
  33.     })
  34.     if err != nil {
  35.         panic(err)
  36.     }
  38.     content, err := configClient.GetConfig(vo.ConfigParam{
  39.         DataId: "user-web.yaml",
  40.         Group:  "dev"})
  42.     if err != nil {
  43.         panic(err)
  44.     }
  45.     fmt.Println(content)
  47.     err = configClient.ListenConfig(vo.ConfigParam{
  48.         DataId: "user-web.yaml",
  49.         Group:  "dev",
  50.         OnChange: func(namespace, group, dataId, data string) {
  51.             fmt.Println("配置文件变化")
  52.             fmt.Println("group:" + group + ", dataId:" + dataId + ", data:" + data)
  53.         },
  54.     })
  55.     time.Sleep(3000 * time.Second)
  57. }

2. 如何将nacos中的配置映射成go的struct

  1. //go语言本身支持将json的字符串反射成struct
