If your csrf middleware is enabled then you will need to pass the token as well

See http://laravel.io/forum/05-08-2015-posting-using-jquery-revamped. Please atttempt a forum search first a lot of answers already there.
also you are better off using a regular route and then doing the logic in controller using a regular MVC pattern. I just don't like cramming code logic in a route that's just me personally.

I don't think his question mentioned posting a form via ajax but rather just posting period. Seems to me he just wants an understanding of why his post is failing instead of a different way to do it.

The title is: ajax post in laravel 5 return error 500 (Internal Server Error). Some think inside the box, some say think outside the box, a better solution is to remove the box completely then think. And yes I made that up.

teach a man to fish

I cannot top that one.

I dont want to use a form, I want to directly send a post request and retrieve the response directly too. If I need crf token, how I'm able to generate a crf token for my ajax post request?

This should do

<a href="#" id="try" data-link="{{ url('/test') }}" data-token="{{ csrf_token() }}">Try</a>

then include it in the request

$("#try").click(function(){
        var url = $(this).attr("data-link");

        //add it to your data
        var data = {
            _token:$(this).data('token'),
            testdata: 'testdatacontent'
        }


        $.ajax({
            url: "test",
            type:"POST",
            data: data,
            success:function(data){
                alert(data);
            },error:function(){ 
                alert("error!!!!");
            }
        }); //end of ajax
    });

Be sure to look through the helpers.php when you get a chance, tons of useful methods in there

What i'm doing in a project is using the csrf_token() in a meta tag.

<meta name="csrf_token" content="{{ csrf_token() }}" />

Then, when I need to make an ajax request, use the beforeSend method.

$("#try").click(function(){
    var url = $(this).attr("data-link");
    $.ajax({
        url: "test",
        type:"POST",
        beforeSend: function (xhr) {
            var token = $('meta[name="csrf_token"]').attr('content');

            if (token) {
                  return xhr.setRequestHeader('X-CSRF-TOKEN', token);
            }
        },
        data: { testdata : 'testdatacontent' },
        success:function(data){
            alert(data);
        },error:function(){ 
            alert("error!!!!");
        }
    }); //end of ajax
});
