【问题描述】：

单击删除项目链接时出现此错误：

RouteCollection.php 第 219 行中的 MethodNotAllowedHttpException：

在 RouteCollection.php 第 219 行

在 RouteCollection.php 第 206 行中的 RouteCollection->methodNotAllowed(array('DELETE'))

这是链接：

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

这就是我在routes.php 尝试处理它的方式：

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

完整的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);
});

【问题讨论】：

请添加完整的路线列表
已添加，请检查修改
您是否也可以通过在命令行中输入“php artisan routes”来检查您的路线
在这里，顺便说一句，我一直在阅读的内容似乎 Thomas 是对的。所以，Laravel 5 essentials book 中有一个错误：-/
是的，Thomas 是对的，我只是在看到您的路线列表后才来申请表单。 @Thomas，谢谢

【解决方案1】：

链接向服务器发送GET 请求，但您的路由期待DELETE 请求。你需要做这样的事情来发送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 请求。没有PUT、PATCH 和DELETE 方法。 Laravel（在某种意义上）通过添加一个名为 _method 的隐藏输入字段来“模拟”这些方法，该字段指定这些方法。

由于 HTML 表单仅支持 POST 和 GET，因此 PUT 和 DELETE 方法将通过自动添加 _method 隐藏字段到您的表单来进行欺骗。
