在Node.js中解析Redis HGETALL对象

Question

我正在尝试解析Node.js中的HGETALL对象.

---

在Redis CLI中:

> HGETALL userList

回报

1) "19578616521094096601"
2) "User 1"
3) "1682930884780137383"
4) "User 2"

---

在节点中:

var redis = require('redis')
,   r = redis.createClient();

console.log(r.HGETALL('userList'));

回报

true

---

我想将userList对象解析为JSON或数组,但我似乎无法弄清楚如何从中提取数据.

RedisClient使用回调来返回结果.

例:

var redis = require('redis'),
    r = redis.createClient();

r.hgetall('userList', function(err, results) {
   if (err) {
       // do something like callback(err) or whatever
   } else {
      // do something with results
      console.log(results)
   }
});
