node.js下redis容易操作实例

redis API：http://redis.readthedocs.org/cn/latest/index.html

在npm目录下，H:\web\nodejs\node_modules\npm

npm install redis

// redis 链接var redis   = require('redis');var client  = redis.createClient('6379','127.0.0.1');

// redis 链接错误
client.on("error",function(error){
    console.log(error);});

// redis 验证 (reids.conf未开启验证，此项可不需要)
client.auth("foobared");
