Functions

func GetEmailCacheKey 

func GetEmailCacheKey(email string) string

GetEmailCacheKey 生成email验证码的cache的key，不需要userID

func GetMobileCacheKey 

func GetMobileCacheKey(mobile string) string

GetMobileCacheKey 生成mobile验证码的cache的key

func GetUserEmailCacheKey 

func GetUserEmailCacheKey(userID string, email string) string

GetUserEmailCacheKey 生成userId+email验证码的cache的key，需要userID

Types

type RedisClient 

type RedisClient struct {
	Addr     string // 例如: xxxxx.a2fdoa.0001.usw2.cache.amazonaws.com:6379
	Password string
	DB       int // 例如：0
}

func (*RedisClient) Connect 

func (r *RedisClient) Connect() *redis.Client

func (*RedisClient) Delete 

func (r *RedisClient) Delete(keys ...string) (int64, error)

Delete 返回删除的key的数量

func (*RedisClient) Exists 

func (r *RedisClient) Exists(key ...string) (int64, error)

Exists 检查某一个或多个key是否存在，如不存在，返回的数字是0

func (*RedisClient) Expire 

func (r *RedisClient) Expire(key string, duration time.Duration) (bool, error)

重设timeout时间 如果key不存在，则返回false；如果原来没有有效期，现在会有有效期

func (*RedisClient) Get 

func (r *RedisClient) Get(key string) ([]byte, error)

Get 返回[]byte，如果不存在，则error为 redis: nil

func (*RedisClient) GetSet 

func (r *RedisClient) GetSet(key string, value interface{}) ([]byte, error)

GetSet 设置新值并获取原来的值，不改变duration。注意，如果没有原来的值，则duration会是永久的 获取：GetSet（原子性），设置新值，返回旧值。比如一个按小时计算的计数器，可以用GetSet获取计数并重置为0。

func (*RedisClient) HMSet 

func (r *RedisClient) HMSet(key string, fields map[string]interface{}) (bool, error)

func (*RedisClient) Incr 

func (r *RedisClient) Incr(key string) (int64, error)

如果key不存在，将key设为"1"；如果key存在，key增加1

func (*RedisClient) Keys 

func (r *RedisClient) Keys(pattern string) (keys []string, err error)

Keys 用于查找所有符合给定模式 pattern 的 key

func (*RedisClient) LikeDeletes 

func (r *RedisClient) LikeDeletes(key string) (int64, error)

func (*RedisClient) MExpire 

func (r *RedisClient) MExpire(keys []string, duration time.Duration) error

自定义的方法，通过pipeline实现批量给key设置过期时间 https://www.jianshu.com/p/4045a3721b3c http://vearne.cc/archives/1113

func (*RedisClient) MGet 

func (r *RedisClient) MGet(keys ...string) ([]interface{}, error)

func (*RedisClient) MPFCount 

func (r *RedisClient) MPFCount(keys []string) (resultMap map[string]int64, err error)

自定义的方法，通过pipeline实现批量PFCount 返回值{"key1": 4, "key2": 18, ...}

func (*RedisClient) MSet 

func (r *RedisClient) MSet(pairs ...interface{}) (string, error)

func (*RedisClient) MSetNX 

func (r *RedisClient) MSetNX(pairs ...interface{}) (bool, error)

func (*RedisClient) PFAdd 

func (r *RedisClient) PFAdd(key string, els ...interface{}) (int64, error)

HyperLogLog http://remcarpediem.net/2019/06/16/用户日活月活怎么统计-Redis-HyperLogLog-详解/

func (*RedisClient) PFCount 

func (r *RedisClient) PFCount(keys ...string) (int64, error)

会将每个key的value merge去重后统计数量

func (*RedisClient) RPush 

func (r *RedisClient) RPush(key string, values ...interface{}) (int64, error)

一次放入多个value进一个list的尾部

func (*RedisClient) RPushX 

func (r *RedisClient) RPushX(key string, value interface{}) (int64, error)

一次放入1个value的尾部

func (*RedisClient) Set 

func (r *RedisClient) Set(key string, value interface{}, duration time.Duration) error

Set 设置key value，如果duration为0，则意味着无有效期，永远存在

func (*RedisClient) SetNX 

func (r *RedisClient) SetNX(key string, value interface{}, duration time.Duration) (bool, error)

SetNX 只有key不存在时，当前set操作才执行

func (*RedisClient) SetXX 

func (r *RedisClient) SetXX(key string, value interface{}, duration time.Duration) (bool, error)

SetXX 只有key存在时，当前set操作才执行

func (*RedisClient) TTL 

func (r *RedisClient) TTL(key string) (time.Duration, error)

TTL 返回 以毫秒为单位的整数值TTL或负值 -1ns, 如果key没有到期超时（没有设置有效期）。-2ns, 如果键不存在(或者键已经过期了)。

func (*RedisClient) ZAdd 

func (r *RedisClient) ZAdd(key string, members ...Z) (int64, error)

func (*RedisClient) ZRange 

func (r *RedisClient) ZRange(key string, start, stop int64) ([]string, error)

注：第一个的index是0

func (*RedisClient) ZRevRange 

func (r *RedisClient) ZRevRange(key string, start, stop int64) ([]string, error)

type Verification 

type Verification struct {
	Redis             *RedisClient
	EmailCodeLength   int           // ie: 6
	EmailCodeTimeout  time.Duration // ie: time.hour * 24
	MobileCodeLength  int           // ie: 6
	MobileCodeTimeout time.Duration // ie: time.minute *30

verification struct

func (*Verification) GetSetEmailVerifyCode added in v1.0.9 

func (v *Verification) GetSetEmailVerifyCode(email string) (code string, err error)

func (*Verification) GetSetUserEmailVerifyCode added in v1.0.8 

func (v *Verification) GetSetUserEmailVerifyCode(userID, email string) (code string, err error)

先尝试获取缓存中保存的Email验证码，如没有，则新设置，效果同SetUserEmailVerifyCode；如有，则取出此code，并重新设置此code的有效期。 这样保证多次设置 UserEmailVerifyCode 获得的code都是相同的
