问题 I'm a bit new to sessions and now when I'm trying to use them the session is always undefined for me when coming to the next page after a successful login as an example. If my login is successful I do the following var session = req.session; session.user_id = String(item._id); session.user_secure = security.security(session.user_id); Then I redirect to another page: res.writeHead(302, { 'Location': '/backstageArea' }); res.end(); And then I try to fin the session again doing this: var session

问题 I am trying to search sears for an item, which I store in a String. I notice that whenever I type: http://www.sears.com/search=summer clothes in the search bar in my google chrome, it automatically converts it to: http://www.sears.com/search=summer%20clothes?catalogId=12605&storeId=10153&levels=Clothing&autoRedirect=true&viewItems=25&redirectType=CAT_REC_PRED Therefore, my strategy is to have Jsoup fetch this site and follow redirects. String url = "http://www.sears.com/search=summer clothes"

问题 I'm getting this problem while executing a modified BluetoothChat app. The app shows the devices, starts connecting to it, and then crashes. I've been testing this and it happens on this thread. Here is the code and the LogCat: public class ConnectedThread extends Thread { // Debugging private static final String TAG = "BluetoothChatService"; private static final boolean D = true; public ConnectedThread(BluetoothSocket socket) { Log.d(TAG, "create ConnectedThread"); GlobalVar.mmSocket =

问题 I am attempting to pass my ENV variable of my stripe publishable key to the stripe.js file for Connect. Dotenv gem: gem 'dotenv-rails', groups: [:development, :test, :production] I added it to my dotenv gem .env file: STRIPE_PUBLISHABLE_KEY=pk_test_xxxxxxxxxx STRIPE_SECRET_KEY=sk_test_xxxxxxxxxx Then added to my stripe.js.erb file: var stripe = Stripe("<%= ENV['STRIPE_PUBLISHABLE_KEY']%>"); changing the stripe.js to stripe.js.erb worked locally, but the ENV doesn't seem to work in production.

问题 I have a site that is functioning fine, but just by refreshing the main page (index_3.php) my error log populates with two warnings. [08-Oct-2013 11:36:09] PHP Warning: session_start() [<a href='function.session-start'>function.session-start</a>]: Cannot send session cache limiter - headers already sent (output started at /home2/mysite/public_html/mysubsite/index_3.php:7) in /home2/mysite/public_html/mysubsite/functions.php on line 12 [08-Oct-2013 11:36:09] PHP Warning: session_regenerate_id(

问题 I'm trying to write audio application for Bluetooth headphones under Linux (over BlueZ stack). It's embedded version so I want to use only C++ and BlueZ without any DBus or Python. For now I could successfully inquire devices and pair with them. But after few seconds connection gets lost. As far as I understand - there's should be some link established after pairing to prevent disconnection. But I can't figure out what am I doing wrong.. Here is my code sample: int main(int argc, char** argv)

问题 I receive always the error " Error: Can't set headers after they are sent. " when calling "res.writeHead(...)" in the very first callback of connect: var http = require('http'); var connect = require('connect'); var simpleApp = connect(); simpleApp .use(function(req, res, next){ res.writeHead(200, { 'content-type': 'text/html' }); res.write('response powered by SIMPLE connect-object as middelware'); console.log('Pre'); next(); console.log('Post'); }) .use(function(req, res, next){ console.log

问题 I am following the Chapter 2 of Jasmin Blanchettes book C++-GUI-Programming-with-Qt-4-1st-ed.pdf trying to setup the dialog GoToCellDialog using MS VS 2008 with Qt. The example compiles, the dialog appears, but it fails to enter the handler method on_lineEdit_textChanged() on text changes. To prove it, i added this line to the slot method: label->setText(tr("Changed :")); to force a visual change in the label. In the .ui file the element <connections/> is empty. I don't know why. I decided to
