jQuery Ajax POST request being sent as GET with Laravel

So I removed the trailing slash and it suddenly worked. I'm not sure why exactly it did, but it did. I posted this question to Laracasts as well. I would recommend that those having the same issue I did to read through the comments and through this other thread so they can follow my steps. I think one of my previous steps resolved a problem so that when I removed the trailing slash this time, it worked. Thanks everyone for your help!
