如何为 Laravel 5.5 中的选定请求 class 设置自定义响应
How to set custom response for selected Request class in Laravel 5.5
我正在尝试使用 Laravel 验证来生成自定义错误消息,但是我找不到我应该覆盖的函数。
路由:POST:/entries/
使用 EntryController@store
,后者使用 EntryStoreRequest
执行验证。
EntryStoreRequest
namespace App\Api\V1\Requests;
class EntryStoreRequest extends ApiRequest
{
/**
* Get the validation rules that apply to the request.
*
* @return array
*/
public function rules()
{
return [
'message' => [
'string',
'required',
'max:65535',
],
'code' => [
'string',
'max:255',
'nullable'
],
'file' => [
'string',
'max:255',
'nullable'
],
'line' => [
'string',
'max:255',
'nullable'
],
'stack' => [
'string',
'max:65535',
'nullable'
]
];
}
}
ApiRequest
namespace App\Api\V1\Requests;
use Illuminate\Foundation\Http\FormRequest;
abstract class ApiRequest extends FormRequest
{
/**
* Determine if the user is authorized to make this request.
*
* @return bool
*/
public function authorize()
{
return true;
}
}
错误当前返回为:
{
"message": "The given data was invalid.",
"errors": {
"message": [
"The message field is required."
]
}
}
我想将它们格式化为:
{
"data": [],
"meta: {
"message": "The given data was invalid.",
"errors": {
"message": [
"The message field is required."
]
}
}
如何在 ApiRequest
class 内实现此目标?
如果您只想为选定的请求 class 自定义验证响应,您需要向此 class 添加 failedValidation()
消息:
protected function failedValidation(\Illuminate\Contracts\Validation\Validator $validator)
{
$response = new JsonResponse(['data' => [],
'meta' => [
'message' => 'The given data is invalid',
'errors' => $validator->errors()
]], 422);
throw new \Illuminate\Validation\ValidationException($validator, $response);
}
这样您就不需要在 Handler 中进行任何更改,并且仅针对单个 class.
使用此自定义响应
如果您想全局更改所有回复的格式,您应该将以下方法添加到 app\Exceptions\Handler.php
文件:
protected function invalidJson($request, ValidationException $exception)
{
return response()->json([
'data' => [],
'meta' => [
'message' => 'The given data is invalid',
'errors' => $exception->errors()
]
], $exception->status);
}
您也可以在 Upgrade guide 的 异常格式 部分
中阅读相关内容
对于那些不想使用 JsonResponse 的人,这是我为自己所做的
protected function failedValidation(Validator $validator) {
// if you want, log something here with $this->validationData(), $validator->errors()
$response = redirect($this->getRedirectUrl())
->with('var1', 'my var 1') // custom flash variable to send if needed
->with('var2', 'my var 2')
->withErrors($validator)
->withInput();
throw new ValidationException($validator, $response);
}
