405: Method Not Found on POST request - php

Question

I am recieving the 405: Method not Found error when trying to perform a POST request on my laravel application. I'm trying to make a forum to learn how to use php and Laravel.
I am trying to post the request from /forum/category/{category}/post, I perform (almost) identical requests from just /forum and it works perfectly, so I assume it's something to do with this.
This is where I'm trying to post the request from (returns post.blade.php):
Route::get('forum/category/{category}/post', 'ForumController#showThreadPostForm');
The request:
var $form = $('form');
$form.submit((e) => {
e.preventDefault();
$.ajax({
type: "POST",
url: 'postthread',
headers: {'X-CSRF-TOKEN': $('meta[name="csrf"]').attr('content')},
data: {"test": "data"},
success: function(res) {
window.location.reload();
console.log(res);
},
error: function(xhr, ajaxOptions, thrownError) {
console.log("Error occured during AJAX request, error code: " + xhr.status);
},
});
});
The route:
Route::post('postthread', 'ForumController#postThread');
The controller method:
public function postThread(Request $request) {
//empty
}
I'm not sure if this information is enough.
Thanks.
I've used the same AJAX request on a different page /forum and it works, I'm not sure how to make it work on this page.

Try to add token to your data and add slash to your url.
also meta tag set to:
<meta name="csrf-token" content="{{ csrf_token() }}">
$.ajax({
type: "POST",
url: '/postthread',
headers: {'X-CSRF-TOKEN': $('meta[name="csrf"]').attr('content')},
data: {"test": "data", "_token": $('meta[name="csrf"]').attr('content')},
success: function(res) {
window.location.reload();
console.log(res);
},
error: function(xhr, ajaxOptions, thrownError) {
console.log("Error occured during AJAX request, error code: " + xhr.status);
},
});
