Laravel: validate json object
提问by MTA
It's the first time i am using validation in laravel. I am trying to apply validation rule on below json object. The json object name is payload and example is given below.
这是我第一次在 laravel 中使用验证。我正在尝试在下面的 json 对象上应用验证规则。json 对象名称是有效负载，示例如下。
payload = {
"name": "jason123",
"email": "[email protected]",
"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"
}
]
}
And the validation code is like below, for testing purpose i am validating name as a digits. When i executed the below code, the above json object is approved and inserted into my database. Instead, it should give me an exception because i am passing name with alpha numeric value, am i doing something wrong:
验证代码如下所示，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，因为我正在传递带有字母数字值的名称，我做错了什么：
public function store(Request $request)
{
$this->validate($request, [
'name' => 'digits',
'age' => 'digits',
]);
}

Please try this way
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());
}
}
digits:value
数字：值
The field under validation must be numeric and must have an exact length of value.
验证中的字段必须是数字，并且必须具有精确的值长度。

I see some helpful answers here, just want to add - that my preference is that controller functions only deal with valid requests. So I keep all validation in the request. Laravel injects the request into the controller function after validating all the rules within the request. With one small tweak (or better yet a trait) the standard FormRequest works great for validating json posts.
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。
Client example.js
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));
project/routes/api.php
项目/路由/api.php
Route::any('endpoint', function (\App\Http\Requests\MyJsonRequest $request){
dd($request->all());
});
app/Http/Requests/MyJsonRequest.php (as generated by php artisan make:request MyJsonRequest)
app/Http/Requests/MyJsonRequest.php（由 生成php artisan make:request MyJsonRequest）
<?php
namespace App\Http\Requests;
use Illuminate\Foundation\Http\FormRequest;
class TrafficRequest 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();
}
}

Your payload should be payload: {then you can do
你的有效载荷应该是payload: {你可以做的
$this->validate($request->payload, [
'name' => 'required|digits:5',
'age' => 'required|digits:5',
]);
or if you are not sending the payload key you can just use $request->all()
或者，如果您不发送有效负载密钥，则可以使用 $request->all()

Use the Validatorfactory class instead using validatemethod derived from controller's trait. It accepts array for the payload, so you need to decode it first
使用Validator工厂类而不是使用validate从控制器特征派生的方法。它接受有效载荷的数组，因此您需要先对其进行解码
\Validator::make(json_decode($request->payload, true), [
'name' => 'digits',
'age' => 'digits',
]);
