Question

我正在开发一个从db表中获取用户的项目。我正在尝试创建更新方法 - SaveUpdatedItems（） ，并且我在提交时合并了表单验证。但是每当我提交不完整的字段时，我都会收到 MethodNotAllowedHttpExException 。我还创建了一个方法 - SaveItems（） ，用于保存新记录并合并表单验证，但我没有收到错误。我对Laravel来说还算新手。我有什么想法得到错误？下面的代码片段。

public function ValidateFormInput($request){
        return $this->validate($request, [
            'name' => 'required',
            'email' => 'required',
            'password' => 'required',
            'role' => 'required',
        ]);
    }

public function SaveUpdatedItems(Request $request){
   $this->ValidateFormInput($request);
}

public function SaveItems(Request $request){

        $this->ValidateFormInput($request);
}

路线：

Route::post('/manage/user/save', 'UserController@SaveItems');
Route::post('/manage/user/saveupdated','UserController@SaveUpdatedItems');

Answer 1

当验证失败时，Laravel会将您重定向回提交无效数据的页面。此重定向将是GET请求。

因此，如果您恰好位于只能通过POST访问的页面上，然后您提交了一个包含验证错误的表单，您将通过GET请求重定向回该页面，从而导致{{1}错误。

Laravel 5.4在执行POST请求时获取MethodNotAllowedHttpException
