Laravel，提交GET表格不会触发路线

So i have a very strange problem occurring at the moment where i have a form that that submits as POST and triggers the route fine, whereas if the the form submits as GET it does not get triggered. It is just the strangest thing, in its simplified form the code looks like:

Works

route

route::post('/contributions/finalise', [ 'as' => 'contributions.finalise', 'uses' => function() {
    dd('i get output');
}]);

form

{!! Form::open(['route' => 'contributions.finalise', 'method' => 'POST']) !!}

    {!! Form::input('hidden','amount', null, ['id' => "contribute-amount"]) !!}

    <button type="submit">Submit</button>

{!! Form::close() !!}

Doesn't work

route

route::get('/contributions/finalise', [ 'as' => 'contributions.finalise', 'uses' => function() {
    dd('i DON'T get output, only a white screen is shown.');
}]);

form

{!! Form::open(['route' => 'contributions.finalise', 'method' => 'GET']) !!}

    {!! Form::input('hidden','amount', null, ['id' => "contribute-amount"]) !!}

    <button type="submit">Submit</button>

{!! Form::close() !!}

As you can see they are very similar but the GET just doesn't work? Am i missing something really basic here?

Thanks for your help

What error show for your post request? I think this will be problem of CSRF Token. Add CSRF Token filed at your form.

{!! Form::open(['route' => 'contributions.finalise', 'method' => 'POST']) !!}
    // Add CSRF Field
    {!! csrf_field() !!}

    {!! Form::input('hidden','amount', null, ['id' => "contribute-amount"]) !!}

    <button type="submit">Submit</button>
{!! Form::close() !!}

So turns out there was a conflicting route that i didn't notice as the contribution was also a resource so it had a whole bunch of routes that i wasn't using.
