golang-redis之hash类型简单操作

1：安装redigo

go get github.com/garyburd/redigo/redis

2：import redigo

import （    "github.com/garyburd/redigo/redis")

3：连接redis

c, err := redis.Dial("tcp", "192.168.2.225:6379")if err != nil {    fmt.Println("connect to redis err", err.Error())    return}defer c.Close()

4：命令执行

n,err := c.Do("hset","key","field","value")  //写result,err := redis.Values(c.Do("hgetall","key"))//读

5：hash常见命令

hset(key, field, value)：向名称为key的hash中添加元素fieldhget(key, field)：返回名称为key的hash中field对应的valuehmget(key, (fields))：返回名称为key的hash中field i对应的valuehmset(key, (fields))：向名称为key的hash中添加元素fieldhincrby(key, field, integer)：将名称为key的hash中field的value增加integerhexists(key, field)：名称为key的hash中是否存在键为field的域hdel(key, field)：删除名称为key的hash中键为field的域hlen(key)：返回名称为key的hash中元素个数hkeys(key)：返回名称为key的hash中所有键hvals(key)：返回名称为key的hash中所有键对应的valuehgetall(key)：返回名称为key的hash中所有的键（field）及其对应的value

6.1：hset示例

_, err = c.Do("hset", "myhash", "bike1", "mobike")if err != nil {    fmt.Println("haset failed", err.Error())}

6.2：hget示例

res, err := c.Do("hget", "myhash", "bike1")fmt.Println(reflect.TypeOf(res))if err != nil {    fmt.Println("hget failed", err.Error())} else {    fmt.Printf("hget value :%s\n", res.([]byte))}

6.3：hmset/hmget

_, err = c.Do("hmset", "myhash", "bike2", "bluegogo", "bike3", "xiaoming", "bike4", "xiaolan")if err != nil {    fmt.Println("hmset error", err.Error())} else {    value, err := redis.Values(c.Do("hmget", "myhash", "bike1", "bike2", "bike3", "bike4"))    if err != nil {        fmt.Println("hmget failed", err.Error())    } else {        fmt.Printf("hmget myhash's element :")        for _, v := range value {            fmt.Printf("%s ", v.([]byte))        }        fmt.Printf("\n")    }}

6.4：hincrby

_, err = c.Do("hmset", "myhash", "bike2", "bluegogo", "bike3", "xiaoming", "bike4", "xiaolan")if err != nil {    fmt.Println("hmset error", err.Error())} else {    value, err := redis.Values(c.Do("hmget", "myhash", "bike1", "bike2", "bike3", "bike4"))    if err != nil {        fmt.Println("hmget failed", err.Error())    } else {        fmt.Printf("hmget myhash's element :")        for _, v := range value {            fmt.Printf("%s ", v.([]byte))        }        fmt.Printf("\n")    }}

6.5：hexists

isExist, err := c.Do("hexists", "myhash", "tmpnum")if err != nil {    fmt.Println("hexist failed", err.Error())} else {    fmt.Println("exist or not:", isExist)}

6.6：hlen

ilen, err := c.Do("hlen", "myhash")if err != nil {    fmt.Println("hlen failed", err.Error())} else {    fmt.Println("myhash's len is :", ilen)}

6.7：hkeys

resKeys, err := redis.Values(c.Do("hkeys", "myhash"))if err != nil {    fmt.Println("hkeys failed", err.Error())} else {    fmt.Printf("myhash's keys is :")    for _, v := range resKeys {        fmt.Printf("%s ", v.([]byte))    }    fmt.Println()}

6.8：hvals

resValues, err := redis.Values(c.Do("hvals", "myhash"))if err != nil {    fmt.Println("hvals failed", err.Error())} else {    fmt.Printf("myhash's values is:")    for _, v := range resValues {        fmt.Printf("%s ", v.([]byte))    }    fmt.Println()}

6.9：hdel

_, err = c.Do("HDEL", "myhash", "tmpnum")if err != nil {    fmt.Println("hdel failed", err.Error())}

6.10：hgetall

result, err := redis.Values(c.Do("hgetall", "myhash"))if err != nil {    fmt.Println("hgetall failed", err.Error())} else {    fmt.Printf("all keys and values are:")    for _, v := range result {        fmt.Printf("%s ", v.([]byte))    }    fmt.Println()}
