How to automatically generate interface documents in PHP back-end function development?

In modern Web application development, the writing and maintenance of interface documents is a very important part. A standardized and clear interface document can greatly improve the work efficiency of the development team, reduce communication costs, and also facilitate other developers to quickly understand and use the interface.

This article will introduce how to use Swagger and PHP annotations to realize the automatic generation of interface documents in the development of PHP back-end functions.

Introduction to Swagger

Swagger is a toolset for defining, building, and using RESTful-style web services. It includes a set of specifications and a set of tools that can automatically generate interface documents, client code, etc. based on the specifications.

Swagger specification uses YAML or JSON format to describe the metadata of the interface, including the URL of the interface, request method, parameters, response data, etc. Through these metadata, Swagger can automatically generate interface documents and provide a beautiful UI interface for developers to view and test the interface.

Installing Swagger

First, we need to install the Swagger PHP library. In PHP development, we can use the two libraries swagger-php and zircote/swagger-php to generate Swagger specification interface documents.

Install via Composerzircote/swagger-php：

composer require --dev zircote/swagger-php

Copy after login

Add Swagger annotations

Next, we need to use Swagger annotations in the PHP code to Metadata describing the interface. Take a simple user registration interface as an example:

/**
 * @SWGPost(
 *   path="/user/register",
 *   tags={"user"},
 *   summary="用户注册",
 *   description="用户注册接口",
 *   @SWGParameter(
 *     name="username",
 *     in="formData",
 *     required=true,
 *     type="string",
 *     description="用户名"
 *   ),
 *   @SWGParameter(
 *     name="password",
 *     in="formData",
 *     required=true,
 *     type="string",
 *     format="password",
 *     description="密码"
 *   ),
 *   @SWGResponse(
 *     response=200,
 *     description="注册成功"
 *   )
 * )
 */
public function register(Request $request)
{
    // 注册逻辑代码
}

Copy after login

In the above code, we use the @SWGPost annotation to mark the URL and request method of the interface, @SWGParameterAnnotations are used to describe the parameters of the interface, and @SWGResponse annotations are used to describe the response data of the interface.

Generate interface document

After configuring Swagger annotations, we can generate interface documents through commands. Execute the following command in the root directory of the project:

vendor/bin/swagger --output public/swagger.json app/Http/Controllers

Copy after login

This command will scan the PHP files in the app/Http/Controllers directory and generate the Swagger specification interface document based on the Swagger annotations. , and save it to the public/swagger.json file.

View the interface document

After the interface document is generated, we can open the Swagger UI interface to view and test the interface.

First, introduce the HTML template file of Swagger UI into the project. Create a public/swagger/index.html file with the following content:

<!DOCTYPE html>
<html>
<head>
    <title>API 文档</title>
    <link rel="stylesheet" type="text/css" href="https://cdn.jsdelivr.net/npm/swagger-ui-dist/swagger-ui.css">
</head>
<body>
    <div id="swagger-ui"></div>
    <script src="https://cdn.jsdelivr.net/npm/swagger-ui-dist/swagger-ui-bundle.js"></script>
    <script>
        window.onload = function () {
            SwaggerUIBundle({
                url: "/swagger.json",
                dom_id: '#swagger-ui'
            });
        }
    </script>
</body>
</html>

Copy after login

Then, we can open the public/swagger/index.html file in the browser to view the interface documentation.

Conclusion

By using Swagger and PHP annotations, we can easily generate interface documents. This not only improves development efficiency, but also makes the definition and use of interfaces more standardized and clear.

In short, in the development of PHP back-end functions, using Swagger and PHP annotations to automatically generate interface documents is a very recommended practice. It not only improves the maintainability and development efficiency of the project, but also facilitates team collaboration and communication.
