From the official Laravel 5 documentation:
来自官方 Laravel 5 文档：
Delete an existing Model
删除现有模型
$user = User::find(1);
$user->delete();
Deleting An Existing Model By Key
通过键删除现有模型
User::destroy(1);
User::destroy([1, 2, 3]);
User::destroy(1, 2, 3);
In every cases, the number between brackets represents the object ID, but you may also run a delete query on a set of models:
在每种情况下，括号之间的数字代表对象 ID，但您也可以对一组模型运行删除查询：
$affectedRows = User::where('votes', '>', 100)->delete();

So the Laravel's way of deleting using the destroyfunction is
所以Laravel使用destroy函数删除的方式是
<form action="{{ url('employee' , $employee->id ) }}" method="POST">
{{ csrf_field() }}
{{ method_field('DELETE') }}
<button>Delete Employee</button>
</form>
You can find an example here http://laravel.com/docs/5.1/quickstart-intermediate#adding-the-delete-buttonAnd your route should look something like this
你可以在这里找到一个例子http://laravel.com/docs/5.1/quickstart-intermediate#adding-the-delete-button你的路线应该是这样的
Route::delete('employee/{id}', array('as' => 'employee.destroy','uses' => 'Employeecontroller@destroy'));
It works with eg:Route::resource('employee', 'EmployeeController');and it should also work with how you set up your destroy route.
它适用于例如：Route::resource('employee', 'EmployeeController');并且它还应该适用于您设置销毁路线的方式。

Obviously you have a bad routing problem. You're trying to use a 'get' verb to reach a route defined with a 'delete' verb.
显然，您的路由问题很严重。您正在尝试使用“get”动词到达用“delete”动词定义的路线。
If you want to use an anchor to delete a record, you should add this route:
如果要使用锚点删除记录，则应添加以下路由：
Route::get('/employee/{id}/destroy', ['uses' => 'EmployeeController@destroy']);
or keep using a delete verb, but then you need to use a form (not an anchor) with a parameter called _methodand value 'delete'stating that you're using a 'delete' verb.
或者继续使用删除动词，但随后您需要使用一个形式（而不是锚点），其中的参数称为_method和值，'delete'说明您正在使用“删除”动词。

Route::get('/showcon/{del_id}/delete','MainController@deletemsg');
public function deletemsg($del_id){
$mail=Mail::find($del_id);
$mail->delete($mail->id);
return redirect()->back();
}
<a href="showcon/{{$m->id}}/delete">del</a>
