## Python操作Redis
### redispy安装及连接
安装
```
pip install redis
```
连接
```
r = redis.StrictRedis(host='localhost',port=6379,db=0)
```
### 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)
```
