如何在Redis中插入哈希映射数组？(Node.js的)

Question

我正在使用Node.js模块node_redis:

var data = [ {'name':'matt', 'id':'333' } , {'name':'Jessica','id':'492'} ] ;

//Initialize Redis
var redis = require('redis'),
rclient = redis.createClient(settings.redis.port, settings.redis.host,{pass:settings.redis.password});
rclient.auth(settings.redis.password, function(){});
rclient.on("error", function (err) {});


//OK, insert the data into redis
rclient.set("mykey", data); 

当我这样做时set,我得到一个错误,为什么？

{ stack: [Getter/Setter],
  arguments: undefined,
  type: undefined,
  message: 'ERR wrong number of arguments for \'set\' command' }
Error: ERR wrong number of arguments for 'set' command

该set方法需要一个字符串作为第二个参数.

你可以将你的data变量字符串化,即

rclient.set("mykey", JSON.stringify(data))
