我正在尝试为API编写CRUD。但是,当验证失败时,我想将错误返回基于json
的响应,而不是将用户重定向到主页。
我可以使用以下代码来做到这一点
public function store(Request $request)
{
try {
$validator = $this->getValidator($request);
if ($validator->fails()) {
return $this->errorResponse($validator->errors()->all());
}
$asset = Asset::create($request->all());
return $this->successResponse(
'Asset was successfully added!',
$this->transform($asset)
);
} catch (Exception $exception) {
return $this->errorResponse('Unexpected error occurred while trying to process your request!');
}
}
/**
* Gets a new validator instance with the defined rules.
*
* @param Illuminate\Http\Request $request
*
* @return Illuminate\Support\Facades\Validator
*/
protected function getValidator(Request $request)
{
$rules = [
'name' => 'required|string|min:1|max:255',
'category_id' => 'required',
'cost' => 'required|numeric|min:-9999999.999|max:9999999.999',
'purchased_at' => 'nullable|string|min:0|max:255',
'notes' => 'nullable|string|min:0|max:1000',
];
return Validator::make($request->all(), $rules);
}
现在,我想将我的一些代码提取到
form-request
中,以进一步清理 Controller 。我喜欢将代码更改为以下代码。public function store(AssetsFormRequest $request)
{
try {
if ($request->fails()) {
return $this->errorResponse($request->errors()->all());
}
$asset = Asset::create($request->all());
return $this->successResponse(
'Asset was successfully added!',
$this->transform($asset)
);
} catch (Exception $exception) {
return $this->errorResponse('Unexpected error occurred while trying to process your request!');
}
}
您可能会说
$request->fails()
和$request->errors()->all()
无法正常工作。如何检查请求是否失败,然后如何从表单请求中获取错误?供您引用,这是我的
AssetsFormRequest
类的外观<?php
namespace App\Http\Requests;
use Illuminate\Foundation\Http\FormRequest;
class AssetsFormRequest extends FormRequest
{
/**
* Determine if the user is authorized to make this request.
*
* @return bool
*/
public function authorize()
{
return true;
}
/**
* Get the validation rules that apply to the request.
*
* @return array
*/
public function rules()
{
return [
'name' => 'required|string|min:1|max:255',
'category_id' => 'required',
'cost' => 'required|numeric|min:-9999999.999|max:9999999.999',
'purchased_at' => 'nullable|string|min:0|max:255',
'notes' => 'nullable|string|min:0|max:1000',
];
}
}
最佳答案
在您的 AssetFormRequest 类中,您可以覆盖 failedValidation 方法以下内容:
public $validator = null;
protected function failedValidation(\Illuminate\Contracts\Validation\Validator $validator)
{
$this->validator = $validator;
}
然后,您的 Controller 方法对 $ validator 对象执行任何您想做的事情。可能类似于以下内容-
if (isset($request->validator) && $request->validator->fails()) {
return response()->json($request->validator->messages(), 400);
}
