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
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 (fmtgithub.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()
}03 edis的打开和关闭方法

)var (r redis.Connerr error
)func InitRedis() {r, err redis.Dial(tcp, 127.0.0.1:6379)if err ! nil {fmt.Println(err)return}
}func CloseRedis() {r.Close()
}func main() {InitRedis()defer CloseRedis()fmt.Println(主程序的操作。。。)
}
04 通过Do执行get和set命令
package mainimport (fmtgithub.com/gomodule/redigo/redis
)var (r redis.Connerr error
)func InitRedis() {r, err redis.Dial(tcp, 127.0.0.1:6379)if err ! nil {fmt.Println(err)return}
}func CloseRedis() {r.Close()
}func main() {InitRedis()defer CloseRedis()// set 操作_, err r.Do(SET, name, 张三)if err ! nil {fmt.Println(err)return}// get 操作var reply interface{}reply, err r.Do(GET, name)if err ! nil {fmt.Println(err)return}fmt.Println(string(reply.([]byte)))
}
05 通过String自动转换字符串

}func CloseRedis() {r.Close()
}func main() {InitRedis()defer CloseRedis()// set 操作_, err r.Do(SET, name, 张三)if err ! nil {fmt.Println(err)return}// get 操作var reply stringreply, err redis.String(r.Do(GET, name))if err ! nil {fmt.Println(err)return}fmt.Println(reply)
}
06 通过Do实现mset和mget的操作
package mainimport (fmtgithub.com/gomodule/redigo/redis
)var (r redis.Connerr error
)func InitRedis() {r, err redis.Dial(tcp, 127.0.0.1:6379)if err ! nil {fmt.Println(err)return}
}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
package mainimport (fmtgithub.com/gomodule/redigo/redis
)var (r redis.Connerr error

}func CloseRedis() {r.Close()
}func main() {InitRedis()defer CloseRedis()_, err r.Do(HSET, user, name, 张三)if err ! nil {fmt.Println(err)return}var reply stringreply, err redis.String(r.Do(HGET, user, name))if err ! nil {fmt.Println(err)return}fmt.Println(reply)
}
08 通过Do实现lpush和lpop以及llen的操作
package mainimport (fmtgithub.com/gomodule/redigo/redis
)var (r redis.Connerr error
)func InitRedis() {r, err redis.Dial(tcp, 127.0.0.1:6379)if err ! nil {fmt.Println(err)return}

}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Redisr.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)
}

}func main() {InitRedis()r : pool.Get()defer r.Close()r.Send(MULTI) // 开启事务// 事务过程中的一些业务操作r.Send(INCR, num1)r.Send(INCR, num2)reply, err : r.Do(EXEC) // 执行事务fmt.Printf(%#v err:%v\n, reply, err)
}
13 实现redigo的本地化
14 对zdpgo_redis的包结构进行调整

}type User struct {Id int json:idName string json:nameAge 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)

}type User struct {Id int json:idName string json:nameAge 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 (fmtgithub.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)},}

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。
