设置laravel来处理端口号？_course

<div class="post-text" itemprop="text"> <p>I am working with nodejs, expressjs, and socket.io I am triggering events on my web app with a mobile phone over the nodejs server.</p> <p>The app is built on javascript but I am using laravel to store data into a database. I am new to nodejs so I am pretty sure if I wanted, I think I could cut out php and just use the whole app with nodejs, but I don't want to. I like laravel and php and it's alread setup, so let me explain my problem.</p> <p>laravel is installed on my server <code>http://example.com/public/</code> laravel's index.php is here. My routes for my data base resources are <code>http://example.com/public/feeds</code>. I can access this fine, but if I want to access my nodejs server I need to use <code>http://example.com:3000</code> which obviously causes a problem.</p> <p>The nodejs/expressjs files are inside <code>http://example.com/public/MY-FILES-HERE</code> but since the nodejs dispatches on <code>http://example.com:3000</code> this throws my laravel routes off.</p> <p>So what I am asking is how do I get it all to work well with eachother? I assume I need to setup a port somehow in laravel.</p> <p><strong>EDIT:</strong> So I am new to the port, and I didnt know there is already a default port set (80). My laravel install is on port 80, and inside here I can listen to calls from port 3000 using socket.io. I did not know that, so I have a page <code>http://my-server-ip:3000/test</code> which has one button and a script that sends the event to the nodejs server and that responds to my script which listens to events on port 3000 and executes a function. Cool stuff here, I hope I made sense I am very new.</p> </div>
