Question

点击删除项链接时出现此错误：

RouteCollection.php第219行中的MethodNotAllowedHttpException：

在RouteCollection.php第219行
     在RouteCollection.php第206行的RouteCollection-＆gt; methodNotAllowed（数组（＆＃39; DELETE＆＃39;））

这是链接：

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

这就是我试图在routes.php处理它的方式：

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

完成routes.php：

<?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);
});

链接会向服务器发送GET个请求，但您的路由需要DELETE个请求。您需要执行以下操作才能发送DELETE请求。

<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个请求。没有PUT，PATCH和DELETE方法。 Laravel（在某种意义上）＆＃34;模拟＆＃34;这些方法通过添加一个名为_method的隐藏输入字段来指定这些方法。

由于HTML表单只支持POST和GET，因此自动在表单中添加_method隐藏字段会欺骗PUT和DELETE方法。
