本文介绍了如何使用Node.js中的Redis模块来创建Redis客户端，并通过该客户端设置和获取Redis中的键值对。首先演示了如何设置一个名为'name'的键并赋值为'Zhentian'。随后展示了如何从Redis中获取另一个键'question'的值。

Let's start practicing using the redis key-value store from our node application. First require the redismodule, and then create a redis client that we can use to call commands on our redis server.

Use the client to set the name key to your name.

var redis = require('redis');
var client = redis.createClient();
client.set("name", "Zhentian");

We already have stored a value in the question key. Use the redis client to issue a get command to redis to retrieve and then log the value.

var redis = require('redis');
var client = redis.createClient();
client.get("question", function(err, data){
    console.log(data);    
});
