在使用express的节点应用程序中,我存储了cookie信息.现在我需要在socket.io中获取存储的cookie信息.我怎么能得到这个？
app.use(function (req, res, next) {
res.cookie('cookieName','1', { maxAge: 50000, httpOnly: true });
});
io.sockets.on('connection', function (socket) {
//here i need to access the cookie.how can i do this
});
在我的应用程序中我使用uncaughtException来处理应用程序错误.在这个如何重新启动服务器.
在postgresql允许的数组类型或整数和text.But我需要创建对象数组.我可以这样做.
myarray text[]; //for text ['a','b','c']
myarray integer[]; //for integer[1,2,3]
我需要创建如下所示的数组
[{'dsad':1},{'sdsad':34.6},{'sdsad':23}]
我不想使用JSON类型.使用数组类型我需要存储对象数组.
In my node application i'm using redis DB to store the data.While getting the stored value using key i'm not getting the expected output.
var redis=require('redis');
var client = redis.createClient();
var pageContent={a: "a", b: "b", c: "c"};
//client.set('A',pageContent);//here i'm setting the value
client.get('A',function(err,res){
if(!err){
Object.keys(res).forEach(function(k){
console.log('key is '+k + ' value is '+res[k]);
});
}
else{
console.log('error');
}
});
Above code is not giving the stored value.While looping the result i'm getting the below error
TypeError: Object.keys called on non-object …Server1.js
var data = querystring.stringify({

http.createServer(function(req, res){

console.log('Path name is '+pathName);
if (reqMethod=='POST' && pathName == '/image') {
//here i need my server1 data..how can i get here.
}
}).listen(4321);
