概述

如果您没有Golang的基础，应该学习如下前置课程。

  • Golang零基础入门
  • Golang面向对象编程
  • Go Web 基础
  • Go语言开发REST API接口_20240728
  • Go语言操作MySQL开发用户管理系统API教程_20240729
  • Redis零基础快速入门_20231227

基础不好的同学每节课的代码最好配合视频进行阅读和学习，如果基础比较扎实，则阅读本教程巩固一下相关知识点即可，遇到不会的知识点再看视频。

视频课程

最近发现越来越多的公司在用Golang了，所以精心整理了一套视频教程给大家，这个是其中的第6部，后续还会有很多。

视频已经录制完成，完整目录截图如下：
在这里插入图片描述

本套课程的特色是每节课都是一个核心知识点，每个视频控制在十分钟左右，精简不废话，拒绝浪费大家的时间。

01 概述

02 建立Redis连接对象

package mainimport ("fmt""github.com/gomodule/redigo/redis"
)func main() {r, err := redis.Dial("tcp", "127.0.0.1:6379")if err != nil {fmt.Println(err)return}defer r.Close()
}

}func CloseRedis() {r.Close()
}func main() {InitRedis()defer CloseRedis()// set 操作// 也一定要注意，是：key1,value1,key2,value2... 的格式_, err = r.Do("MSET", "name", "张三", "age", 22, "gender", "男")if err != nil {fmt.Println(err)return}// get 操作// 这个传递的是想要哪些keyvar reply []stringreply, err = redis.Strings(r.Do("MGET", "name", "age", "gender"))if err != nil {fmt.Println(err)return}fmt.Println(reply)
}

07 通过Do实现hset和hget的操作

09 Redis的连接池介绍

10 Redis连接池的创建和使用

package mainimport ("fmt""github.com/gomodule/redigo/redis"
)var (pool *redis.Poolerr  error
)func InitRedis() {pool = &redis.Pool{MaxIdle:     16,MaxActive:   1024,IdleTimeout: 300,Dial: func() (redis.Conn, error) {return redis.Dial("tcp", "127.0.0.1:6379")},}

}func main() {InitRedis()r := pool.Get()defer r.Close()// 写入缓冲r.Send("SET", "name1", "张三")r.Send("SET", "name2", "李四")// 清空缓冲，写入服务端（Redis）r.Flush()// 读取：先进先出receive, err := r.Receive()fmt.Printf("receive:%#v, err:%v\n", receive, err)receive, err = r.Receive()fmt.Printf("receive:%#v, err:%v\n", receive, err)// 因为没有数据了，所以会一直处于等待状态receive, err = r.Receive()fmt.Printf("receive:%#v, err:%v\n", receive, err)
}

12 Redis的事务操作

package mainimport ("fmt""github.com/gomodule/redigo/redis"

}

13 实现redigo的本地化

14 对zdpgo_redis的包结构进行调整

15 发布zdpgo_redisv1.1.0版本

16 新增用户

package mainimport ("encoding/json""fmt""github.com/zhangdapeng520/zdpgo_redis"
)var (pool *zdpgo_redis.Poolerr  error
)func InitRedis() {pool = &zdpgo_redis.Pool{MaxIdle:     16,MaxActive:   1024,IdleTimeout: 300,Dial: func() (zdpgo_redis.Conn, error) {return zdpgo_redis.Dial("tcp", "127.0.0.1:6379")},}
}type User struct {Id   int    `json:"id"`Name string `json:"name"`Age  int    `json:"age"`
}func main() {InitRedis()r := pool.Get()defer r.Close()// string  hash  list// string  hash users:{1:{id:1,xxx},2:xxx}// string 代码会更简单zs := User{2, "李四", 23}key := fmt.Sprintf("user/%d", zs.Id)zsBytes, _ := json.Marshal(zs)value := string(zsBytes)r.Do("SET", key, value)value2, _ := zdpgo_redis.String(r.Do("GET", key))fmt.Println(value2)
}

17 修改用户

package mainimport ("encoding/json""fmt""github.com/zhangdapeng520/zdpgo_redis"
)var (pool *zdpgo_redis.Poolerr  error
)func InitRedis() {pool = &zdpgo_redis.Pool{MaxIdle:     16,MaxActive:   1024,IdleTimeout: 300,Dial: func() (zdpgo_redis.Conn, error) {return zdpgo_redis.Dial("tcp", "127.0.0.1:6379")},}
}type User struct {Id   int    `json:"id"`Name string `json:"name"`Age  int    `json:"age"`
}func main() {InitRedis()r := pool.Get()defer r.Close()id := 1name := "李四"// 查询key := fmt.Sprintf("user/%d", id)value2, _ := zdpgo_redis.String(r.Do("GET", key))fmt.Println(value2)// 解析var user Userjson.Unmarshal([]byte(value2), &user)fmt.Println(user)// 修改user.Name = name// 重新存储jsonBytes, _ := json.Marshal(user)fmt.Println(string(jsonBytes))r.Do("SET", key, string(jsonBytes))
}

18 删除用户

package mainimport ("fmt""github.com/zhangdapeng520/zdpgo_redis"

}type User struct {Id   int    `json:"id"`Name string `json:"name"`Age  int    `json:"age"`
}func main() {InitRedis()r := pool.Get()defer r.Close()id := 1// 查询key := fmt.Sprintf("user/%d", id)value2, _ := zdpgo_redis.String(r.Do("GET", key))fmt.Println(value2)// 删除r.Do("DEL", key)// 再查询value2, _ = zdpgo_redis.String(r.Do("GET", key))fmt.Println(value2)
}

19 查询所有用户

package mainimport ("encoding/json""fmt""github.com/zhangdapeng520/zdpgo_redis"
)var (pool *zdpgo_redis.Poolerr  error
)func InitRedis() {pool = &zdpgo_redis.Pool{MaxIdle:     16,MaxActive:   1024,IdleTimeout: 300,Dial: func() (zdpgo_redis.Conn, error) {return zdpgo_redis.Dial("tcp", "127.0.0.1:6379")},}
}type User struct {Id   int    `json:"id"`Name string `json:"name"`Age  int    `json:"age"`
}func main() {InitRedis()r := pool.Get()defer r.Close()// 获取所有的keyuserKeys, _ := zdpgo_redis.Strings(r.Do("KEYS", "user/*"))fmt.Println(userKeys)// 查询var users []Userfor _, key := range userKeys {var user UseruserStr, _ := zdpgo_redis.String(r.Do("GET", key))json.Unmarshal([]byte(userStr), &user)users = append(users, user)}fmt.Println(users)

总结

本套教程主要讲解Go语言操作Redis基础知识，然后还讲解了管道，连接池，事务等高级用户。借助用户管理这个业务为中心，详细讲解了如何使用Go语言加Redis实现用户的增删改查操作，之后有结合httprouter的用法，开发用户管理的增删改查API接口。

通过本套课程，能帮你入门Go语言操作Redis的技术。
