[英]Laravel delete method gives "Method not allowed" error on yajra datatable
我的以下 Laravel 函數有問題，刪除選項不起作用，它發出“不允許方法”錯誤，出於某種奇怪的原因，即使我給它一個路由的 id，它也無法顯示整個頁面.
這是視圖，admin.unsertable。 我只想更正“刪除”錯誤

它的控制器稱為 AdminController，它運行以下方法，該方法與數據庫通信並刪除行。 數據庫是定義好的，因為如果它用fetch_data的方法給我帶來數據
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>';
}
}
這些是路線
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 方法設置為POST ，而 Laravel 路由方法設置為delete 。 您可以設置一個名為_method的參數，其值為'delete' ，以及標題上的crsf token和名為_token的參數。 此外，Laravel 路由需要 uri 中的參數{id} ，而您沒有傳遞它。
如果您有 csrf 令牌 ia 元標記，如下所示：
<!-- CSRF Token -->
<meta name="csrf-token" content="{{ csrf_token() }}">
你可以從那里得到它
var token = $('meta[name="csrf-token"]').attr('content');
但是，如果您在刀片中，則可以直接使用csrf_token()助手
var token = '{{ csrf_token() }}';
然后，將令牌分配給 ajax 標頭：
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': token,
'X-Requested-With': 'XMLHttpRequest',
}
});
設置名為_method的參數值為'delete'並設置名為_token的參數為令牌值：
$(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) {
//...
}
})
}
});
從你的 Laravel 路由中刪除 {id} 參數，因為你沒有使用它：
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) {
//...
}
})
}
});
