I have a free php based Heroku app and I have a php login system. I would like users to be able to chat via socket.io after logging in. I can run either the node.js server or the php server, but not both. I have researched and it looks like that is not possible. I do not want to re code the login system for node.js, what can I do to allow them to chat while keeping the php login system?
It's not currently possible to have a websockets server running alongside a PHP app on Heroku. Only web dynos can receive HTTP traffic on Heroku, and only on the specified port.

I have a PHP application running with Nginx on a Linux server and it has a successful integration with my Active Directory using LDAP.
In the current scenario, the user is able to create a new login for the app or use his Windows credentials to log into the application.
Now, I'm trying to implement a complete Single-Sign On (SSO) and the user logged with his credentials in the Windows machine in the domain will be able to open the app logged without use the credentials again.
Doing some research on it, since my Linux server are not in the same domain, the best options is use NTLM (old and insecure), Kerberos protocol or Negotiate protocol (that will choose among NTLM and Kerberos for each request), depending on Windows version and what is implemented in the Domain Controller.
There is a lot of tutorials in the internet and also some good threads on the theme here in SO. This another link shows a good overview about the options using Apache as web server (for Kerberos option, I found a Nginx port, so this is not the main problem).
Well, I created some test application using these approaches (including all changes in the browser side, limited to Firefox), but all of then are dependents of Web Server (Apache, Nginx or even IIS). Since My app already has a complete integration with AD through LDAP, I'm interested in some Web Server independent solution. Are there any way to "bypass" the authentication in Web Server and get the information about the logged user direct on my PHP code (Client (Firefox) to Server (PHP))?
My best guesses for now are some type of "pure" PHP implementation of Kerberos, that needs of a PECL module or NTLM, that is insecure and still asks for the user credentials in the first request.
I know that maybe its impossible, but I'm asking it for the case that I missed something important information in this research. Is it possible to get the windows user info direct in PHP?
If you don't insist on nginx use Apache Web Server 2.4 with mod_auth_gssapi this is great, high quality code written by people who know what they do. I have been doing this for years for my PHP stuff.
I am trying to develop a socket.io application. It is just a simple application like the one on the Getting Started - Chat application tutorial in the Socket.IO webpage. But the problem is that, I do not want to have the socket.io server serve the client automatically, because I am planning to have a page (in PHP) have a script that can simultaneously be updated by data from a server in real-time using Socket.IO. I just want a certain client that can connect to the server and let them communicate, not a page served by the socket.io server.
Is this possible? Can you please give an idea on how can it be done. Thanks.
That chat tutorial is just a simple deployment where your own web page wants to connect back to the same server that the web page came from. That is not the only way to do it.
The socket.io client code can be served from anywhere. You can even link to a CDN and get it from there instead of from your own server.
And, likewise, the client can connect to any compatible server as long as the server is configured to accept a connection from your page.
If you're looking for how to connect to a different server, you just specify the URL of the desired host in io.connect() like this:
var socket = io.connect('http://www.example.com');
I'm developing a real time chat component for existing system written by PHP which is running on LAMP stack. I used node.js, Express.js and Socket.io for the implementation. Lets say the system is running on a vhost, http://product.loc. I am running the node server in 127.0.0.1:3000.
My chat component which is written in side the system initiates a socket with node server. It works fine. But, i wrote a simple cookie authentication logic in node server, it does not work. cookies are not parsing the node server. i know this is a cross domain issue. But no idea how to resolve this as i am a newbie to Node stuff. Can anybody please help me?
I want a develop a web application with php, and I want a run my apps with a android device. But my device will not be connected to internet, so I must create a local server on the device to run my php code. Is it possible? And if it's possible how?
Based on this page, developing Web Server for mobile devices is still on the research phase. Most probably you would need to use some kind of simulator for Android and develop your App on powerful desktop PC.
EDIT: Looks like such a server exists for Android.
Please use KSWEB.apk. This app supports PHP, SQL, html, csc, but it requires 3 android devices. The first serves as router, the 2nd device is a local server and the 3rd devices is a monitor.
I'm not sure about your need to have a web server running on your phone, but if you have a wireless router and your phone can connect to it, can you not install an Apache server with PHP support on your development PC and access it via your phone's wireless connection?
I will be developing an application for a club where they will have visitors use biometric systems(finger print) or magnetic cards to mark their attendance.
This application is planned as a web app, made using PHP/MySQL/Javascript. It does a lot of other things as well.
What I wanted to find out is how is the interface between Biometric/Megnetic Card systems to a web app done?
I've never worked on this and am hoping if someone who has experience with this can throw some light on this as to how this could be accomplished. Any pointers will be appreciated.
Also, we will be hosting this application remotely. So we won't have physical access to the web-server.
(I'm afraid there's got to be some form of application installed on a pc that would interface with the hardware and probably makes calls to the web app. But, if there was a way to connect it to the web app directly, then the app would be easy to deploy to any location with minimal installation.)
Thanks! :)
How is the hardware connected? Directly to the app server, or to a standalone box of some sort? If it's a standalone box, then yes you'll have to have some kind of program on the box collect the data and send it to the web app. If it's connected directly to the app server, then you need to write something that either polls the hardware or receives messages/events from the driver and DTRT wrt the web app.
There three type of communication channels are supported by the biometric machines. They are serial, TCP/IP and HTTP. In your case, you either need to implement TCP/IP or HTTP.
If your application is running the intranet, then you can implement the TCP/IP server application and host at a intranet system which is expected to write in a common database between the biometric application and your web-app.
If your application is hosted at the server, then you can implement the http server and associated the URL with the machine. For this you need buy the http api supported machines. Here is the google search link for finding such machines.
