错误“POST http://127.0.0.1:8000/get-data-by-id 404（未找到）

Question

晚上好，我是 Laravel 的新手，正在尝试一个用于内部网站的应用程序。 尝试将变量（BuffaloID）从视图传递到控制器并从数据库中获取该特定 ID 的数据，然后返回到视图，显示具有该特定 ID 数据的模式。 在做同样的事情时，我收到错误““POST http://127.0.0.1:8000/get-data-by-id 404（未找到）” 任何人都可以帮助我...在此先感谢

web.php 文件

Route::post('get-data-by-id/{buffaloid}',[BuffaloMonitorController::class,'getbuffaloidformonitor'])->name('getbuffaloidformonitor');
('getbuffaloidformonitor');

BuffalomonitorController 文件

     public function getbuffaloidformonitor(Request $req )
        {

            
            $inspectionbuffaloid = ($buffaloid);
            

            $viewinspectiondata = buffalomonitor::where ('buffaloID','=','$inspectionbuffaloid')->get(); // get data for view inspection data for selected buffaloID

            
            return view ('pages.Buffalo.BuffaloMonitor',['viewinspectiondata'=>$viewinspectiondata]);

            
        }
            
            
            
        }

BuffaloMonitor.blade.php

                   <script>

                $.ajaxSetup({
                headers: {
                    'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
                }
                }); 

        // get data from table and show in View modal by Buffalo ID.


                $(document).on('click', '.viewmonitormodal', function() {

                    var modal_data = $(this).data('info').split(',');
                    
                    $('#viewbuffaloID').val(modal_data[1]);

                    var buffaloid = document.getElementById('viewbuffaloID').value // get buffalo id from textbox to get data for that ID
                    var token = "{{ csrf_token()}}";

                    alert(buffaloid);

                    $.ajax({
                        type                :'POST',
                        url                 :"{{ url('get-data-by-id') }}",
                        //dataType          : 'json',
                        data                :{buffalo_id:buffaloid, _token: token},

                        success:function(refbuffaloid){

                            alert(buffaloid);
                        
                        }
                    });

路线 尝试查看文档，因为您的路线应该是

// and import the BuffaloController on the top like
// use App\Http\Controllers\BuffalomonitorController

Route::get('get-data-by-id/{id}',[BuffaloMonitorController::class, 'getbuffaloidformonitor')->name('getbuffaloidformonitor'); // remove anything after this

控制者 应该知道您将传递它一个 id，因此将其作为参数输入

public function getbuffaloidformonitor($BuffaloId, $Request $req)
        {
            return $BuffaloId;
        }

作为一种常见做法，如果您将 ID 传递给路由，您应该将其设为 get 请求，然后像 url(.... "get-data-by-id" . $buffaloID) 一样发送请求。

                  $.ajax({
                        type                :'GET',
                        url                 :"{{ url('get-data-by-id') }}" + buffaloid // not sure about this routing but just add the buffaloid to the url
                        success:function(refbuffaloid){

                            alert(buffaloid);
                        
                        }
                    });

您的路线需要您需要传递给控制器​​的参数，但控制器不知道该参数。您需要将其作为参数传递给控制器​​方法。

路线：

Route::post('get-data-by-id/{buffaloid}',[BuffaloMonitorController::class,'getbuffaloidformonitor'])->name('getbuffaloidformonitor');

控制器（清理了一下}：

public function getbuffaloidformonitor(Request $request, string $buffaloid )
{
    $viewinspectiondata = buffalomonitor::where('buffaloID', (int)$buffaloid)->get();

    return view ('pages.Buffalo.BuffaloMonitor' ['viewinspectiondata'=>$viewinspectiondata]);
    
}
