Php laravel 5：当我将其从路由移动到控制器时，该功能不起作用,php,ajax,model-view-controller,controller,laravel-5,Php,Ajax,Model View Controller,Controller,Laravel 5,我尝试在使用laravel 5的项目中使用ajax，但只有当我将此函数放在routes文件中时，它才会起作用： Route::post('/post/post_up',function(){ if (Request::ajax()){ $raa=Input::get('_user');

我尝试在使用laravel 5的项目中使用ajax，但只有当我将此函数放在routes文件中时，它才会起作用：

Route::post('/post/post_up',function(){
                                        if (Request::ajax()){
                                            $raa=Input::get('_user');
                                            if ($raa=='null') {
                                                return 'Vous devez connecter';
                                            }else{
                                            $already_vote = \App\Post_vote::where('user_id','=',Input::get('_user'))->where('post_id','=',Input::get('_post'))->count();
                                                if ($already_vote==0) {
                                                    $post = new \App\Post_vote;
                                                    $post->post_id=Input::get('_post');
                                                    $post->user_id=Input::get('_user');
                                                    $post->vote=1;
                                                    $post->save();
                                                    return 'Votre vote bien enregistre';
                                                }else{
                                                    return 'Vous avez déja voté pour ce sujet !';
                                                }
                                            }
                                        }
                                    });

Route::post('/post/post_up','VoteController@post_up');

<?php namespace App\Http\Controllers;

use App\Http\Requests;
use App\Http\Controllers\Controller;

use Illuminate\Http\Request;

class VoteController extends Controller {

public function post_up()
{   
    if (Request::ajax()){
        $raa=Input::get('_user');
        if ($raa=='null') {
            return 'Vous devez connecter';
        }else{
        $already_vote = \App\Post_vote::where('user_id','=',Input::get('_user'))->where('post_id','=',Input::get('_post'))->count();
            if ($already_vote==0) {
                $post = new \App\Post_vote;
                $post->post_id=Input::get('_post');
                $post->user_id=Input::get('_user');
                $post->vote=1;
                $post->save();
                return 'Votre vote bien enregistre';
            }else{
                return 'Vous avez déja voté pour ce sujet !';
            }
        }
    }
}

}

但是当我尝试将此函数从routes.php移动到我的控制器时，它不起作用，我不知道为什么它在routes.php上起作用，在我的控制器上也不起作用。我就是这么做的：

Route::post('/post/post_up',function(){
                                        if (Request::ajax()){
                                            $raa=Input::get('_user');
                                            if ($raa=='null') {
                                                return 'Vous devez connecter';
                                            }else{
                                            $already_vote = \App\Post_vote::where('user_id','=',Input::get('_user'))->where('post_id','=',Input::get('_post'))->count();
                                                if ($already_vote==0) {
                                                    $post = new \App\Post_vote;
                                                    $post->post_id=Input::get('_post');
                                                    $post->user_id=Input::get('_user');

                                                }

您必须在ajax url参数中传递正确的url
$(document).ready(function(){
    //pour vote up
    $('#post_up').submit(function(e){
        e.preventDefault();
        var _post = $('#_post').val();
        var _user = $('#_user').val();
        var _token = $('input[name="_token"]').val();
        var data = new FormData();
        data.append('_token',_token);
        data.append('_user',_user);
        data.append('_post',_post);

        $.ajax({
            type:"POST",
            method:"POST",
            url:"/post/post_up",
            data:data,
            processData: false,
            contentType: false,
            success: function(data){
                alert(data);
            }
        });
    }); });
