Question

I am sending a huge amount of array data through ajax using Laravel. But every time it's giving me MethodNotAllowedHttpException in RouteCollection.php error. Below is the AJAX code

AJAX Code

function getDataSet(data){
         $.ajax({
            url: base_url+'/get-data-set',
            data:{'data':data},      
            type:"POST",
            success:function(response){
                console.log(response);
            },              
         });        
    }

Answer 1

You may use incorrect route post request. To easy maintenance in your route should following

Route::post('/get-data-set',function(){ /* Do something*/ })->name('post.data');

And ajax code should

function getDataSet(data){
     $.ajax({
        url: "{{ route('post.data') }}",
        data:{'data':data},      
        type:"POST",
        success:function(response){
            console.log(response);
        },              
     });        
}

Answer 2

You forgot csrf token on your post request.

function getDataSet(data){
     $.ajax({
        url: base_url+'/get-data-set',
        data:{
            'data':data,
            "_token": "{{ csrf_token() }}"
        },      
        type:"POST",
        success:function(response){
            console.log(response);
        },              
     });        
}
