[英]REST API post field validation Laravel 5.1
I need to check if I have all posted variables are required or else throw error. 我需要检查是否所有发布的变量都是必需的,否则抛出错误。 Till Now I am doing like this
直到我现在这样
Routes.php routes.php文件
Route::post('/api/ws_fetchuser', 'UserController@fetch_user_details');
UserController.php UserController.php
<?php
namespace App\Http\Controllers;
use App\Http\Requests;
use Illuminate\Http\Request;
use App\User;
class UserController extends Controller
{
public function fetch_user_details(Request $request)
{
if(!empty($request) && $request->id!='')
{
print_r($request->id);
}
else
{
return response(array(
'error' => false,
'message' =>'please enter all form fields',
),200);
}
}
}
I am checking like this $request->id!=''
, is there any validation rules or methods which I can use to check id is required field. 我正在检查像这样
$request->id!=''
,是否有任何验证规则或方法可以用来检查id是必填字段。
I have added this validation in my controller as well but what if id is not present how can I show the error? 我也已在控制器中添加了此验证,但是如果不存在id怎么办,如何显示错误?
Updated Validation Code: 更新的验证码:
public function fetch_user_details(Request $request)
{
$this->validate($request, [
'id' => 'required'
]);
print_r($request->id);
}
$this->validate()
methods designed to redirect back when validation failed, So instead of that you can create a validator instance and get the error list manually. $this->validate()
方法旨在在验证失败时重定向回去,因此,您可以创建一个验证器实例并手动获取错误列表,而不是重定向到该方法。
use Validator;
$validator = Validator::make($request->all(), [
'id' => 'required'
]);
if ($validator->fails()) {
return json_encode($validator->errors()->all());
}
