上篇文章简单说了下linux安装redis的过程,这里就是用python代码稍加演练,首先用pip安装redis:
sudo pip install redis
然后就可以在python中调用了,下面写了些基础的东西,按着redis实战里面的介绍来写。关于redis的复杂的使用以后用到再来学习,代码更直观:
import redis cache = redis.StrictRedis(host=‘localhost‘, port=6379) #1. 简单的get和set操作print u‘====set操作:‘cache.set(‘blog:title‘, u‘the5fire的技术博客‘)print cache.get(‘blog:title‘) #真实应用场景,批量set和getfor i in range(10): cache.mset({ ‘blog:post:%s:title‘ % i: u‘文章%s标题‘ % i, ‘blog:post:%s:content‘ % i: u‘文章%s的正文‘ % i }) post_list = []for i in range(10): post = cache.mget(‘blog:post:%s:title‘ % i, ‘blog:post:%s:content‘ % i) if post: post_list.append(post) for title, content in post_list: print title, content #2、 hashed类型的操作print u‘====hashed操作:‘cache.hset(‘blog:info‘,‘title‘, u‘the5fire的技术博客‘)cache.hset(‘blog:info‘,‘url‘, u‘http://www.the5fire.com‘) blog_info_title = cache.hget(‘blog:info‘, ‘title‘)print blog_info_title blog_info = cache.hgetall(‘blog:info‘)print blog_info #同样hashed类型的set和get也可以进行批量操作cache.hmset(‘blog:info‘, { ‘title‘: ‘the5fire blog‘, ‘url‘: ‘http://www.the5fire.com‘, })blog_info1 = cache.hmget(‘blog:info‘, ‘title‘, ‘url‘)print blog_info1 #3、lists类型的操作print u‘====lists操作:‘cache.lpush(‘blog:tags‘, ‘python‘)cache.lpush(‘blog:tags‘, ‘linux‘)tags = cache.lrange(‘blog:tags‘, 0, 2)print tags #对应的还有rpush,lpop,rpop,更多可以看红丸的redis实战 #4、sets类型的操作print u‘====sets操作:‘cache.sadd(‘blog:category:python‘, ‘001‘)cache.sadd(‘blog:category:python‘, ‘002‘)#cache.sadd(‘blog:category:python‘, ‘001‘, ‘002‘) print cache.smembers(‘blog:category:python‘)cache.srem(‘blog:category:python‘, ‘001‘)print cache.smembers(‘blog:category:python‘)
