如何使用golang (beego)在redis中放置无过期的缓存

import (
    "github.com/astaxie/beego"
    "github.com/go-redis/redis"
)

var redisClient *redis.Client

func init() {
    redisClient = redis.NewClient(&redis.Options{
        Addr:     "localhost:6379", // Redis服务器地址
        Password: "",               // Redis服务器密码
        DB:       0,                // Redis数据库索引
    })
}

func PutCache(key string, value string) {
    err := redisClient.Set(key, value, 0).Err()
    if err != nil {
        beego.Error("Failed to put cache:", err)
    }
}

func GetCache(key string) (string, error) {
    value, err := redisClient.Get(key).Result()
    if err != nil {
        return "", err
    }
    return value, nil
}
