這個怎麼樣
var flow = require('flow'); //for async calls
var redis = require("redis").createClient();
function AddUser(user,callback){
flow.exec(
function(){
//AI for Keep unique
redis.incr('nextUserId',this);
},
function(err,userId){
if(err) throw err;
this.userId = userId;
redis.lpush('users',userId,this.MULTI());
redis.hmset('user:'+userId+':profile',user,MULTI());
},
function(results){
results.forEach(function(result){
if(result[0]) throw result[0];
});
callback(this.userId);
}
);
}
user_rahul = {username: 'rahul'};
user_namita = {username: 'namita'};
//Add user
AddUser(user_rahul,function(userId){
console.log('user Rahul Id' + userId);
});
AddUser(user_namita,function(userId){
console.log('user Namita Id' + userId);
});
//users
function Users(callback){
var users = [];
flow.exec(
function(){
redis.lrange('users',0,-1,this);
},
function(err,userIds){
if(err) throw err;
flow.serialForEach(userIds,function(userId){
redis.hgetall('user:'+userId+':profile',this);
},
function(err,val){
if(err) throw err;
users.push(val);
},
function(){
callback(users);
});
}
);
}
//call
Users(function(users){
console.log(users);
});
我已經完成了client.keys(「users *」) – XMen 2011-06-04 07:35:34
您應該謹慎使用該函數。這是一個非常好的功能,但它也是Redis中速度最慢的功能之一。因此,它有機會拖動您的網站性能。如果你想這樣做,那麼你應該使用一套。 – Colum 2011-06-04 11:19:57
