How to use the Hyperf framework for parameter verification

Introduction:
Parameter verification is a very important part when developing Web applications. Proper parameter validation can improve the security and stability of your application. This article will introduce how to use the Hyperf framework for parameter verification and provide specific code examples.

1. Install the Hyperf framework
   First, we need to install the Hyperf framework. You can install the Hyperf framework through Composer and execute the following command:

   composer create-project hyperf/hyperf-skeleton

2. Create controller
   In the Hyperf framework, we can handle requests through the controller. First, we need to create a controller. Execute the following command in the terminal to generate the controller file:

   php bin/hyperf.php gen:controller TestController

3. Define the request parameter class
   Next, we need to define a request parameter class for receiving and verifying the request parameters. . Create a TestRequest.php file in the app/Request directory. The code example is as follows:

   <?php
   
   declare(strict_types=1);
   
   namespace AppRequest;
   
   use HyperfValidationRequestFormRequest;
   
   class TestRequest extends FormRequest
   {
    public function rules(): array
    {
        return [
            'name' => 'required',
            'age' => 'required|numeric',
        ];
    }
   
    public function attributes(): array
    {
        return [
            'name' => '姓名',
            'age' => '年龄',
        ];
    }
   }

4. Modify the controller
   Next, we need to modify the controller to use the request we defined Parameter class. In the index method in TestController.php, the code example is as follows:

   <?php
   
   declare(strict_types=1);
   
   namespace AppController;
   
   use AppRequestTestRequest;
   use HyperfHttpServerAnnotationController;
   use HyperfHttpServerAnnotationPostMapping;
   use HyperfDiAnnotationInject;
   
   /**
    * @Controller()
    */
   class TestController
   {
    /**
     * @Inject
     * @var TestRequest
     */
    private $testRequest;
   
    /**
     * @PostMapping(path="index")
     */
    public function index()
    {
        $data = $this->testRequest->validated();
   
        // 处理请求数据
        // ...
   
        return $data;
    }
   }

5. Add route
   We also need to add a route to map the request to our controller. Add the following code to the config/routes.php file:

   <?php
   
   declare(strict_types=1);
   
   use HyperfHttpServerRouterRouter;
   
   Router::addRoute(['GET', 'POST', 'HEAD'], '/test/index', 'App\Controller\TestController@index');

6. Start the application
   Now that we have completed the parameter verification settings, we can start the Hyperf framework application. Execute the following command in the terminal:

   php bin/hyperf.php start

Test:
Use tools such as Postman to send a POST request to http://127.0.0.1:9501/test/index, and pass it correctly The request parameters are as follows:

{
    "name": "张三",
    "age": 25
}

If the request parameters comply with the defined rules, we will get the correct response.
If the request parameters do not comply with the defined rules, we will get an error response and include the corresponding error message.

Summary:
This article introduces how to use the Hyperf framework for parameter verification. By defining a request parameter class and using the request parameter class in the controller, we can easily implement parameter validation. Parameter verification can help us ensure the stability and security of the application and reduce potential errors and attacks. Hope this article is helpful to you.
