class RedisTT(object):

def __init__(self):

self.host = 'localhost'

self.port = '6379'

self.r = redis.StrictRedis(host=self.host, port=self.port)


def insertRedis(self, keyName, jsonStr): # 存入到redis中

self.r.lpush(keyName, jsonStr)



def save1():

someexpert = {}

someexpert['id'] = 10000

someexpert['realname'] = 'expert-a'

someexpert['organization'] = 'BUAA'

if RedisTT().r.exists('someexpert'):

RedisTT().r.delete('someexpert') # 删除key为someexpert的键值对

RedisTT().insertRedis(keyName='someexpert', jsonStr=json.dumps(someexpert))



def save2():

frameworks = ['vue', 'react', 'angular']

if RedisTT().r.exists('frameworks'):

RedisTT().r.delete('frameworks') # 删除key为frameworks的键值对

RedisTT().insertRedis(keyName='frameworks', jsonStr=json.dumps(frameworks))


if __name__ == "__main__":

save1()

save2()


print(RedisTT().r.lrange('someexpert', 0, RedisTT().r.llen('someexpert')))

print(RedisTT().r.lrange('frameworks', 0, RedisTT().r.llen('frameworks')))
