Here is an analysis of laravel's verification of submitted data, how to customize the content of the error output

Run the command in the root directory

php artisan make:request PostUpdateRequest

will be in the appHttpRequests directory Create a PostUpdateRequest file

For example, I set

public function rules()
{
  return [
    'posts_title' => 'required',//必填
  ];
}

Add the following messages in the PostUpdateRequest file to define the error message

public function messages(){
    return [
      'posts_title.required' =>json_encode( ['status'=>false,'message'=>'标题必须填'],JSON_UNESCAPED_UNICODE),
    ];
}

Pay attention to the above JSON_UNESCAPED_UNICODE

to do an experiment

echo json_encode("PHP中文网");

output Content:

"\u811A\u672C\u4E4B\u5BB6"
