Question

我对以下Laravel函数有问题，删除选项不起作用，它发出“方法不允许”错误，由于某些奇怪的原因，即使我给它指定了ID，也无法显示整个页面。

这是可管理的视图。我只想更正“删除”错误

其控制器称为AdminController，它运行以下方法，该方法与数据库通信并删除该行。定义了数据库，因为如果使用fetch_data方法将数据带给我

public function deleteuser(Request $request){
    if($request->ajax())
    {
        DB::table('users')->where('id', $request->id)->delete();
        echo '<div class="alert alert-success">Data deleted</div>';
    }
}

这些是路线

Route::get('/admin/usertable', 'AdminController@listuser')    
->middleware('is_admin')    
->name('admin.usertable');

Route::get('/admin/usertable/fetch_data', 'AdminController@fetch_data')    
->middleware('is_admin')    
->name('admin.usertable');

Route::delete('/admin/usertable/deleteuser/{id}', 'AdminController@deleteuser')    
->middleware('is_admin')    
->name('admin.deleteuser');

ajax方法设置为POST，而Laravel route方法设置为delete。您可以设置值为_method的名为'delete'的参数，也可以在标题和名为crsf token的参数中设置_token。另外，Laravel路由在uri中需要一个参数{id}，而您没有传递它。

如果您有csrf令牌，则我是一个元标记，例如：

<!-- CSRF Token -->
<meta name="csrf-token" content="{{ csrf_token() }}">

您可以从那里得到它

var token = $('meta[name="csrf-token"]').attr('content');

但是，如果您位于刀片服务器中，则可以直接使用csrf_token()帮助程序

var token = '{{ csrf_token() }}';

然后，将令牌分配给ajax标头：

$.ajaxSetup({
    headers: {
        'X-CSRF-TOKEN': token,
        'X-Requested-With': 'XMLHttpRequest',
    }
});

设置值为_method的参数'delete'，并设置标记值为_token的参数：

$(document).on('click', '.delete', function() {
    var id = $(this).attr("id");
    if(confirm("Estas seguro de esto?"))
    {
        $.ajax({
            url:"{{ route('admin.deleteuser') }}",
            method:"POST",
            data:{
                id:id,
                // set a parameter named _method with value 'delete'
                _method: 'delete',
                // set a parameter named _token with the token value
                _token: token
            },
            success:function(data) {
                //...
            }
        })
    }
});

从您的Laravel路由中删除{id}参数，因为您没有使用它：

Route::delete('/admin/usertable/deleteuser', 'AdminController@deleteuser')    
->middleware('is_admin')    
->name('admin.deleteuser');

更新

$(document).on('click', '.delete', function() {
    var token = '{{ csrf_token() }}';
    $.ajaxSetup({
        headers: {
            'X-CSRF-TOKEN': token,
            'X-Requested-With': 'XMLHttpRequest',
        }
    });
    var id = $(this).attr("id");
    if(confirm("Estas seguro de esto?"))
    {
        $.ajax({
            url:"{{ route('admin.deleteuser') }}",
            method:"POST",
            data:{
                id:id,
                _method: 'delete',
                _token: token
            },
            success:function(data) {
                //...
            }
        })
    }
});
