字符串相关操作

import redis

class TestString(object):
    def __init__(self):
        self.r = redis.StrictRedis(host='192.168.75.130',port=6379)
    #设置值
    def test_set(self):
        res = self.r.set('user1','juran-1')
        print(res)
    #取值
    def test_get(self):
        res = self.r.get('user1')
        print(res)
    #设置多个值
    def test_mset(self):
        d = {
            'user2':'juran-2',
            'user3':'juran-3'
        }
        res = self.r.mset(d)
    #取多个值
    def test_mget(self):
        l = ['user2','user3']
        res = self.r.mget(l)
        print(res)
    #删除
    def test_del(self):
        self.r.delete('user2')

列表相关操作

class TestList(object):
    def __init__(self):
        self.r = redis.StrictRedis(host='192.168.75.130',port=6379)
    #插入记录
    def test_push(self):
        res = self.r.lpush('common','1')
        res = self.r.rpush('common','2')
        # res = self.r.rpush('jr','123')
    #弹出记录
    def test_pop(self):
        res = self.r.lpop('common')
        res = self.r.rpop('common')
    #范围取值
    def test_range(self):
        res = self.r.lrange('common',0,-1)
        print(res)

集合相关操作

class TestSet(object):
    def __init__(self):
        self.r = redis.StrictRedis(host='192.168.75.130', port=6379)
    #添加数据
    def test_sadd(self):
        res = self.r.sadd('set01','1','2')
        lis = ['Cat','Dog']
        res = self.r.sadd('set02',lis)
    #删除数据
    def test_del(self):
        res = self.r.srem('set01',1)
    #随机删除数据
    def test_pop(self):
        res = self.r.spop('set02')

哈希相关操作

class TestHash(object):
    def __init__(self):
        self.r = redis.StrictRedis(host='192.168.75.130', port=6379)

    #批量设值
    def test_hset(self):
        dic = {
            'id':1,
            'name':'huawei'
        }
        res = self.r.hmset('mobile',dic)
    #批量取值
    def test_hgetall(self):
        res = self.r.hgetall('mobile')
    #判断是否存在 存在返回1  不存在返回0
    def test_hexists(self):
        res = self.r.hexists('mobile','id')
        print(res)
