AJAX 请求中不允许使用 Laravel 405 方法

Question

The code works just fine on my local dev environment, but gives a 405 method not allowed exception when I upload it to the server. The solutions on this question and this question didn't work for me.

Here's the controller.

    public function DeleteMultipleProjects(Request $request){
        $json = $request->projectsToDelete;
        $to_delete = collect([]);

        $projects = json_decode($json);
        foreach ($projects as $project) {
            $to_delete->push($project->id);
        }

        Project::destroy($to_delete);
    }

Here's the corresponding entry in the routes file.

Route::post('/ajax/dashboard/delete-projects', 'ProjectController@DeleteMultipleProjects');

And here's the AJAX call to the URL.

    $.ajax({
        url: '/ajax/dashboard/delete-projects',
        method: 'POST',
        data: {
            projectsToDelete: JSON.stringify(vThis.selectedProjects),
        },
        complete: function(){
            vThis.refreshProjects();
        }
    });

This is what the data looks like for an example test case.

[{"id":140,"name":"a","updated_at":"Sun, Oct 21, 2018 4:31 AM","selected":true,"selectHovering":false},{"id":139,"name":"New Project","updated_at":"Sun, Oct 21, 2018 4:31 AM","selected":true,"selectHovering":false}]

How can I get past this error, and why does this only happen in production?

Edit It's worth noting that I have other AJAX calls to routes throughout my application, and they work fine.

Answer 1

It seems you are missing the csrf token

Update your ajax post data as:

$.ajax({
    url: '/ajax/dashboard/delete-projects',
    method: 'POST',
    data: {
        projectsToDelete: JSON.stringify(vThis.selectedProjects),
        _token: '{{ csrf_token() }}',
    },
    complete: function(){
        vThis.refreshProjects();
    }
});

A 405 error in Laravel means the route does not exist for the HTTP method you are using.

If you are receiving this error on production but not locally, it would indicate your route files are either outdated or have been cached.

Clear your route cache with:

php artisan route:clear

Verify your POST route exists with:

php artisan route:list --path=ajax/dashboard/delete-projects

If route:list confirms your POST route exists but you're still receiving a 405, the other thing that can lead to cached routes is opcache without revalidating timestamps, in which you may need to restart your php processes to clear.

The problem was in the data that I was sending. I'm not sure why, but my server didn't like the entire projects array, so I updated it to send just an array of the id s I'd like to delete, and consequently updated the controller to just destroy the request. If someone has an explanation, I'm curious.
