Laravel 5.7 抛出 Symfony \ Component \ HttpKernel \ Exception \ MethodNotAllowedHttpException 调用更新函数时没有消息错误

Question

我一直在使用 ajax post 使用 Laravel 5.2 成功更新我的数据库信息。视图、控制器和模型已经到位，但是当我使用 Laravel 5.7 实现它时，我收到了这个错误

Symfony\Component\HttpKernel\Exception\> MethodNotAllowedHttpException 没有消息。

使用 Laravel 5.7 是否需要进行任何更改或调整？请帮忙。谢谢

查看：

<form class="update-member-form" id="update-member-form" enctype="multipart/form-data">
   {{ csrf_field() }}

   <input type="text" name="id" class="form-control" id="primary_id" value="">

      <div class="form-group">
        <label for="recipient-name" class="col-form-label">Member ID:</label>
        <input type="text" name="member_id" class="form-control" id="member_id" value="" required>
      </div>
      <div class="form-group">
        <label for="recipient-name" class="col-form-label">First Name:</label>
        <input type="text" name="fname" class="form-control" id="editMember_name" value="" required>
      </div>
      <div class="form-group">
        <label for="recipient-name" class="col-form-label">Middle Name:</label>
        <input type="text" name="mname" class="form-control" id="editMember_mname" value="" required>
      </div>
      <div class="form-group">
        <label for="recipient-name" class="col-form-label">Last Name:</label>
        <input type="text" name="lname" class="form-control" id="editMember_lname" value="" required>
      </div>
</form>

<div class="modal-footer">
    <button type="button" class="btn btn-secondary" data-dismiss="modal" onClick="window.location.reload()" >Close</button>
    <button type="button" class="btn btn-primary btn-update-member">Save updates</button>
  </div>

Javascript

$(".btn-update-member").click(function(e){

      e.preventDefault();

      $.post("{{ url('/updatemember') }}", $("#update-member-form").serialize(), function(data){

            if(data.notify == "Success"){

                swal({
                      title: "Record successfully updated",
                      text: "Message will close in 2 seconds",
                      type: "success",
                      timer: 2000
                    });

            } else{

              console.log(data.notify);

            }


          },"json"); 

      });

web.php

Route::post('/updatemember', 'MembersController@update');

控制器

public function update(Request $request, $id)
{
    //
    $updateMember = Member::where( 'id', $request['id'] )
                          ->update( $request->all() );

       if( $updateMember ){

         $notification = "Success";

       } else{

         $notification = "Failed";

       }

     return json_encode( array( 'notify'=>$notification ) );
}

错误：

Answer 1

这行代码对我有用。只需添加->except('_token')

 Member::where( 'id', $request['id'])->update($request->except('_token'));

Answer 2

好的，开始吧 会员.php

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Member extends Model
{
    // if you changed the primary key id you need to set it here
    protected $primaryKey = 'primary_id';
    protected $guarded = [];
    // Also to work it with route model binding you need this too
    public function getRouteKeyName()
    {
        return 'primary_id';
    }
}

然后是web.php

// Get The Form name param has to be the same name as the controller variable
Route::get('/members/{member}/edit', 'MembersController@edit');
// Patch the form. 
// Not post because you are not creating. 
// Not put because you are not replacing. 
// Patch because you are updating 
Route::patch('/members/{member}/edit', 'MembersController@update')->name('member.update');

然后是 MembersController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Member;

class MembersController extends Controller
{
    // Bind the route to the model. It throws 404 if the member does not exit;
    public function edit(Request $request, Member $member)
    {
        return view('members.edit', compact('member'));
    }

    public function update(Request $request, Member $member)
    {
        die('i am here update');
    }
}

当然还有表格

<form class="update-member-form" id="update-member-form" enctype="multipart/form-data">
   @csrf
   @method('PATCH') 
    <div class="form-group">
      <label for="recipient-name" class="col-form-label">Member ID:</label>
      <input type="text" name="member_id" class="form-control" id="member_id" value="{{$member->member_id}}" required>
    </div>
    <div class="form-group">
      <label for="recipient-name" class="col-form-label">First Name:</label>
      <input type="text" name="fname" class="form-control" id="editMember_name" value="{{$member->fname}}" required>
    </div>
    <div class="form-group">
      <label for="recipient-name" class="col-form-label">Middle Name:</label>
      <input type="text" name="mname" class="form-control" id="editMember_mname" value="{{$member->mname}}" required>
    </div>
    <div class="form-group">
      <label for="recipient-name" class="col-form-label">Last Name:</label>
      <input type="text" name="lname" class="form-control" id="editMember_lname" value="{{$member->lname}}" required>
    </div>
</form>

<div class="modal-footer">
    <button type="button" class="btn btn-secondary" data-dismiss="modal" onClick="window.location.reload()" >Close</button>
    <button type="button" class="btn btn-primary btn-update-member">Save updates</button>
  </div>
<script src="https://code.jquery.com/jquery-3.3.1.min.js" integrity="sha256-FgpCb/KJQlLNfOu91ta32o/NMZxltwRo8QtmkMRdAu8=" crossorigin="anonymous"></script>
<script>
  $(".btn-update-member").click(function(e){

  e.preventDefault();

  $.post("{{ route('member.update', $member->primary_id) }}", $("#update-member-form").serialize(), function(data){

        if(data.notify == "Success"){

            swal({
                  title: "Record successfully updated",
                  text: "Message will close in 2 seconds",
                  type: "success",
                  timer: 2000
                });

        } else{

          console.log(data.notify);

        }


      },"json"); 

  });
</script>

当然，您可以避免路由模型绑定，从输入字段中获取 id，或者只是从路由中获取 int id，然后通过 db 查询成员是否退出和 bla bla bla。

Answer 3

问题是您正在使用 POST 但实际上您必须执行 PUT 才能修复此添加

<input name="_method" type="hidden" value="PUT">

在表单之后你只需粘贴这个

别忘了

<form method="post">

Answer 4

如果你已经放了参数，那么从方法中删除 id：

public function update(Request $request)
{
    $updateMember = Member::where( 'id', $request['id'] )
                          ->update( $request->all() );    
       if( $updateMember ){    
         $notification = "Success";    
       } else{    
         $notification = "Failed";    
       }    
     return json_encode( array( 'notify'=>$notification ) );
}

或

您必须将路线更改为：

Route::post('/updatemember/{id}', 'MembersController@update');

还有在js中：

$.post("{{ url('/updatemember/yourid') }}", $("#update-member-form").serialize(), function(data){
            if(data.notify == "Success"){
             ...
            } else{
              console.log(data.notify);
            }

编辑： 您必须在 id 输入中传递值为空的值：

<input type="text" name="id" class="form-control" id="primary_id" value="">

Answer 5

您的路线错误，因为您在更新函数中将$id 作为参数传递，因此请同时更新您的视图文件

Route::post('/updatemember', 'MembersController@update');

改为

Route::post('/updatemember/{id}', 'MembersController@update');
