How to use the Hyperf framework for interface document generation

With the rapid development of web applications, the writing and maintenance of interface documents has become more and more important. Interface documents can help developers better understand and use APIs, improve development efficiency and collaborative development capabilities. In daily development, we often need to manually write and update interface documents, which is a relatively tedious and error-prone task. In order to solve this problem, we can use the automatic tools of the Hyperf framework to generate interface documents through annotations.

Hyperf framework is a high-performance framework based on Swoole and Hyperf components. It provides a series of annotations to simplify the development process. Among them, we can use the "@RequestMapping" annotation to define the interface, and use the "@Api" annotation to generate the interface document.

First, we need to introduce the Hyperf framework and corresponding dependencies into the project. Add the following content to the composer.json file:

{
    "require": {
        "hyperf/http-server": "^2.0",
        "phpstan/phpstan": "^0.9.0",
        "phpstan/phpstan-strict-rules": "^0.9.0",
        "symfony/console": "^5.0"
    }
}

and then execute the composer update command to install the dependencies.

Next, we create a controller to define the interface. Create an IndexController.php file in the app/Controller directory. The code is as follows:

<?php

declare(strict_types=1);

namespace AppController;

use HyperfHttpServerAnnotationController;
use HyperfHttpServerAnnotationRequestMapping;
use HyperfDiAnnotationInject;
use HyperfContractStdoutLoggerInterface;
use AppServiceHelloService;

/**
 * @Controller()
 * @Api(name="Hello接口")
 */
class IndexController
{
    /**
     * @Inject()
     * @var HelloService
     */
    private $helloService;

    /**
     * @RequestMapping(path="/hello/{name}", methods="get")
     * @param string $name
     */
    public function hello(string $name)
    {
        return $this->helloService->sayHello($name);
    }
}

In the above code, we define an IndexControllerController, and uses the @RequestMapping annotation on the hello method to define the interface. In addition, we also used the @Api annotation to generate the interface document, and used the @Inject annotation to inject the HelloService service.

Next, we can use the custom command of the Hyperf framework to generate the interface document. Create a doc directory in the project root directory and create a generate.php file in it. The code is as follows:

<?php

declare(strict_types=1);

use HyperfCommandCommand as HyperfCommand;
use HyperfCommandAnnotationCommand;
use PsrContainerContainerInterface;
use HyperfApiDocCommandGenerateApiDocCommand;

/**
 * @Command
 */
class DocCommand extends HyperfCommand
{
    /**
     * @var ContainerInterface
     */
    protected $container;

    public function __construct(ContainerInterface $container)
    {
        $this->container = $container;

        parent::__construct('doc:generate');
    }

    public function configure()
    {
        parent::configure();
        $this->setDescription('Generate api doc for the project');
    }

    public function handle()
    {
        $command = new ApiDocCommand($this->container);
        $command->setOutput($this->output);
        $command->setInput($this->input);
        return $command->handle();
    }
}

In the above code, we create A custom DocCommand command is created, and the ApiDocCommand command provided by the Hyperf framework is called in the handle method to generate the interface document.

Finally, we execute the php doc/generate.php command in the terminal to generate the interface document. After successful execution, we can find the generated interface document in the public directory under the project root directory.

Through the above steps, we successfully generated the interface document using the Hyperf framework. By defining interfaces through annotations, we can write documents more concisely and reduce the workload of manually writing documents. At the same time, the custom commands provided by the Hyperf framework also make the document generation process more convenient.

In summary, using the Hyperf framework to generate interface documents not only improves development efficiency, but also ensures the accuracy and consistency of the documents. I hope this article can be helpful to everyone when using the Hyperf framework to generate interface documents.
