如何處理Laravel

Question

DELETE請求

我得到這個錯誤，當我點擊刪除項目鏈接：

MethodNotAllowedHttpException在RouteCollection.php行219：

在RouteCollection.php線219

在RouteCollection-> methodNotAllowed（陣列（ '刪除'））在RouteCollection.php線206

這是鏈接：

<a href="{{ url('cats/'.$cat->id.'/delete') }}"> 
    <span class="glyphicon glyphicon-trash"></span> 
    Delete 
</a> 

這是我怎樣，我想在routes.php作出處理：

Route::delete('cats/{cat}/delete', function(Furbook\Cat $cat){ 
    $cat->delete(); 
    return redirect('cats')->withSuccess('Cat has been deleted'); 
}); 

完全routes.php文件：

<?php 
/* 
|-------------------------------------------------------------------------- 
| Application Routes 
|-------------------------------------------------------------------------- 
| 
| Here is where you can register all of the routes for an application. 
| It's a breeze. Simply tell Laravel the URIs it should respond to 
| and give it the controller to call when that URI is requested. 
| 
*/ 

Route::get('/', function() { 
     return redirect('cats'); 
}); 

Route::get('cats', function() { 
    $cats = Furbook\Cat::All(); 
     return view('cats.index')->with('cats',$cats); 
}); 

Route::get('cats/create', function(){ 
    return view('cats.create'); 
}); 

Route::post('cats', function(){ 
    $cat = Furbook\Cat::create(Input::all()); 
    return redirect('cats/'.$cat->id)->withSuccess('Cat has been created'); 
}); 

Route::get('cats/{id}', function ($id) { 
    $cat = Furbook\Cat::findOrNew($id); 
    return view('cats.show')->with('cat',$cat); 
}); 

Route::get('cats/{cat}', function(Furbook\Cat $cat){ 
    return view('cats.show')->with('cat',$cat); 
}); 

Route::delete('cats/{cat}/delete', function(Furbook\Cat $cat){ 
    $cat->delete(); 
    return redirect('cats')->withSuccess('Cat has been deleted'); 
}); 

Route::get('about', function() { 
     return view('about')->with('number_of_cats',9000); 
}); 

Route::get('cats/breeds/{name}', function ($name) { 
    $breed = Furbook\Breed::with('cats') 
     ->whereName($name) 
     ->first(); 
     $cats = null; 
     if(isset($breed)) 
       $cats=$breed->cats; 
    return view('cats.index') 
     ->with('breed',$breed) 
     ->with('cats',$cats); 
});

Answer 1

鏈接發送GET請求到服務器，但您的路由期待DELETE請求。你需要做這樣的事情來發送DELETE請求。

<form method="POST" action="{{ url('cats/'.$cat->id.'/delete') }}"> 
    {{ csrf_field() }} 
    <input type="hidden" name="_method" value="DELETE"> 
    <span class="glyphicon glyphicon-trash"></span> 
    <button type="submit">Delete</button> 
</form> 

在HTML中，只有GET和POST請求。沒有PUT,PATCH和DELETE方法。 Laravel（某種意義上）通過添加一個名爲_method的隱藏輸入字段來「嘲笑」這些方法，該字段指定了這些方法。

由於HTML表單只支持POST和GET，所以PUT和DELETE方法將被欺騙，方法是自動向表單中添加一個_method隱藏字段。
