Laravel的XMLHttpRequest MethodNotAllowedHttpException在RouteCollection.php線218：

Question

我使用laravel php和XMLHttpRequest的（上載圖像）和我得到以下錯誤

MethodNotAllowedHttpException在RouteCollection.php線218

以下是我處理表單JavaScript代碼提交：

$(document).on('submit','form',function(e){ 
    e.preventDefault(); 
    $form=$(this); 
    uploadImage($form); 

    }); 

    function uploadImage($form){ 
    $form.find(".progress-bar").removeClass("progress-bar-success").removeClass("progress-bar-danger"); 
    var formdata=new FormData($form[0]); 
    var request=new XMLHttpRequest(); 

    // progress event... 

    request.upload.addEventListener('progress',function(e){ 

    var percent=Math.round(e.loaded/e.total * 100); 
    console.log('progress: '+percent); 
    $form.find('.progress-bar').width(percent+'%').html(percent+'%'); 

    }); 
    // progress completed load event 

    request.upload.addEventListener('load',function(e){ 

    var percent=e.loaded/e.total * 100; 
    console.log('load: '+percent); 
    $form.find('.progress-bar').addClass('progress-bar-success').html('upload completed'); 

    }); 


    request.open('post','productImage.add'); 
    request.send(formdata); 

    $form.on('click','.cancel',function(){ 

    request.abort(); 
    $form.find('.progress-bar').addClass('progress-bar-danger').removeClass('progress-bar-success').html('upload aborted...'); 

    }); 

}

這是我的HTML形式，其信息發送到PHP的路線

<form role="form"> 
        <label>Product Image:</label> 
        <input type="file" name="image"> 
        <button type="submit" class="btn btn-info btn-sm upload">Upload</button> 
        <button type="button" class="btn btn-danger btn-sm cancel">Cancel</button> 
        <div class="progress progress-striped active">     
         <div class="progress-bar" style="width:0%"></div> 
        </div> 

      </form> 

這是我的路線文件：

路線::組（[ '前綴'=> '管理員']，功能（ ）{

Route::get('/', function() { 

     return view('welcome'); 

    }); 

    Route::auth(); 

    Route::get('/home', [ 

     'uses'=>'HomeController@index', 
     'as'=>'home' 

     ]); 

    Route::post('/productAdd', [ 

     'uses'=>'productsController@add', 
     'as'=>'product.add' 

    ]); 

    Route::post('/productImageAdd', [ 

     'uses'=>'productsController@addImage', 
     'as'=>'productImage.add' 

    ]); 

}); 

最後，這是我的帖子控制器代碼：

class productsController extends Controller 
{ 
    function add(Request $request){ 

     $product= new product(); 
     $product->productName=$request["name"]; 
     $product->description=$request["description"]; 
     $product->discount=$request["discount"]; 

     $request->user()->products()->save($product); 
     return redirect()->route('home'); 

    } 

    function addImage(Request $request){ 
     print_r($request); 
    } 




}

你忘了托克n爲CSRF保護。 將此隱藏字段添加到您的表單中：

<input type="hidden" name="_token" value="{{ csrf_token() }}"> 

應該這樣做！

編輯：不要忘記發送_token與您的請求。
