Laravel:验证json对象

Question

这是我第一次在laravel中使用验证.我试图在下面的json对象上应用验证规则.json对象名称是有效负载,下面给出了示例.

payload = {
  "name": "jason123",
  "email": "email@xyz.com",
  "password": "password",
  "gender": "male",
  "age": 21,
  "mobile_number": "0322 8075833",
  "company_name": "xyz",
  "verification_status": 0,
  "image_url": "image.png",
  "address": "main address",
  "lattitude": 0,
  "longitude": 0,
  "message": "my message",
  "profession_id": 1,
  "designation_id": 1,
  "skills": [
    {
      "id": 1,
      "custom" : "new custom1"
    }
   ]
}

验证码如下所示,出于测试目的,我将名称验证为数字.当我执行下面的代码时,上面的json对象被批准并插入到我的数据库中.相反,它应该给我一个例外,因为我传递名称与字母数字值,我做错了什么:

public function store(Request $request)
{

    $this->validate($request, [
        'name' => 'digits',
        'age' => 'digits',
        ]);
}

Answer 1

请尝试这种方式

use Validator;

public function store(Request $request)
{
    //$data = $request->all();
    $data = json_decode($request->payload, true);
    $rules = [
        'name' => 'digits:8', //Must be a number and length of value is 8
        'age' => 'digits:8'
    ];

    $validator = Validator::make($data, $rules);
    if ($validator->passes()) {
        //TODO Handle your data
    } else {
        //TODO Handle your error
        dd($validator->errors()->all());
    }
}

数字:值

验证字段必须是数字,并且必须具有确切的值长度.

我在这里看到了一些有用的答案，只是想补充一下 - 我的偏好是控制器功能只处理有效的请求。所以我在请求中保留所有验证。Laravel 在验证请求中的所有规则后将请求注入控制器函数。通过一个小的调整（或者更好的特性），标准的 FormRequest 非常适合验证 json 帖子。

客户端示例.js

var data = {first: "Joe", last: "Dohn"};
var xmlhttp = new XMLHttpRequest();
xmlhttp.open("POST",'//laravel.test/api/endpoint');
xmlhttp.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
xmlhttp.send(JSON.stringify(data));

项目/路由/api.php

Route::any('endpoint', function (\App\Http\Requests\MyJsonRequest $request){
    dd($request->all());
});

app/Http/Requests/MyJsonRequest.php（由 生成php artisan make:request MyJsonRequest）

<?php
namespace App\Http\Requests;
use Illuminate\Foundation\Http\FormRequest;
class MyJsonRequest extends FormRequest{

    public function authorize(){
        return true;//you'll want to secure this
    }

    public function rules(){
        return [
            'first' => 'required',
            'last'  => 'required|max:69',
        ];
    }

    //All normal laravel request/validation stuff until here
    //We want the JSON...
    //so we overload one critical function with SOMETHING LIKE this
    public function all($keys = null){
        if(empty($keys)){
            return parent::json()->all();
        }

        return collect(parent::json()->all())->only($keys)->toArray();
    }
}
