连接阿波罗：

默认properties类型

go 复制代码

package main

import (
	"fmt"

	"github.com/apolloconfig/agollo/v4"
	"github.com/apolloconfig/agollo/v4/env/config"
)

func main() {
	c := &config.AppConfig{
		AppID:          "2222",
		Cluster:        "dev",
		IP:             "http://192.168.0.52:8080/",
		NamespaceName:  "100086.properties",
		IsBackupConfig: true,
		Secret:         "36ae07ed3b8d4885b2c7fa8538c091c1",
	}

	client, _ := agollo.StartWithConfig(func() (*config.AppConfig, error) {
		return c, nil
	})
	fmt.Println("初始化Apollo配置成功")

	//Use your apollo key to test
	cache := client.GetConfigCache(c.NamespaceName)
	value, _ := cache.Get("2323423")
	fmt.Println(value)
}

json类型

go 复制代码

package main

import (
	"fmt"

	"github.com/apolloconfig/agollo/v4"
	"github.com/apolloconfig/agollo/v4/env/config"
)

func main() {
	c := &config.AppConfig{
		AppID:          "2222",
		Cluster:        "dev",
		IP:             "http://192.168.0.52:8080/",
		NamespaceName:  "1008611.json",
		IsBackupConfig: true,
		Secret:         "36ae07ed3b8d4885b2c7fa8538c091c1",
	}

	client, _ := agollo.StartWithConfig(func() (*config.AppConfig, error) {
		return c, nil
	})
	fmt.Println("初始化Apollo配置成功")

	//Use your apollo key to test
	cache := client.GetConfigCache(c.NamespaceName)
	cache.Range(func(key, value interface{}) bool {
		fmt.Println(key, value)
		return true
	})
	// fmt.Println(value)
}

连接redis

集群：

go 复制代码

package main

import (
	"context"
	"fmt"
	"time"

	"github.com/redis/go-redis/v9"
)

func main() {
	
	rdb := redis.NewClusterClient(&redis.ClusterOptions{
		Addrs:    Jobconfig.Redis.Ip,
		Password: Jobconfig.Redis.Password,
		PoolSize: 10,
	})
	err := rdb.Ping(context.Background()).Err()
	if err != nil {
		panic("redis初始化出现问题")
	}
	fmt.Println("连接成功")
	time.Sleep(10 * time.Second)
}

单机：

go 复制代码

	rdb := redis.NewClient(&redis.Options{
		Addr:     "192.168.0.52:6379",
		Password: "lushouxin@123", // no password set
		DB:       0,               // use default DB
	})
	err := rdb.Ping(context.Background()).Err()
	if err != nil {
		panic("redis初始化出现问题")
	}
	RDB = rdb
	log.Info("redis初始化成功")
