保持与socket.io-redis的聊天历史

Question

我和socket.io和redis聊天。我的问题是，我怎样才能从插座房中回收所有排放物？Chat正在工作，只需刷新所有丢失的消息。下面是我管理红宝石店的方法。

var redis = require('redis').createClient;
var adapter = require('socket.io-redis');
var pub = redis(port, host, {});
var sub = redis(port, host, { detect_buffers: true});
io.adapter(adapter({ pubClient: pub, subClient: sub }));

http://www.ibm.com/developerworks/library/wa-bluemix-html5chat/index.html那篇文章解决了这个问题。步骤4包含了答案。代码：

var redis = require('redis');
var redisClient = redis.createClient(port, host);
redisClient.lpush('messages', JSON.stringify(data)); // push into redis
redisClient.lrange('messages', 0, 99, function(err, reply) {
  //reply contains all messages
});
