PHP and Laravel integrate to implement Swagger interface documentation and testing

In today's increasingly open Internet environment, APIs have become the main means of communication between various applications. With API interfaces, we can easily connect various applications to each other, thereby achieving more complex application scenarios. However, the writing and maintenance of API interface documents, as well as interface testing, are relatively difficult tasks. In order to solve this problem, Swagger interface documentation and testing tools came into being.

Swagger is a standardized and complete framework for generating, describing, invoking, and visualizing RESTful-style web services. Swagger is open source on GitHub and maintained in OpenAPI. Swagger assists developers in designing, building, documenting, and testing RESTful APIs throughout their lifecycle. For PHP developers, you can use Swagger PHP and Laravel integration to write and display API interface documents.

This article will introduce how to use PHP and Laravel to integrate Swagger to write and test API interface documents.

1. Install Swagger PHP

First, we need to install the Swagger PHP package. You can install it through Composer, open the terminal, enter the Laravel project directory, and execute the following command:

composer require zircote/swagger-php

2. Install Swagger UI

Swagger UI is an open source, interactive page used to display API documents defined by the Swagger specification. It includes a front-end library for rendering API documentation utilizing Swagger, ReDoc, and Swagger-UI. You can install it through npm or directly download the source code of Swagger UI.

Here, we use Composer to install and execute the following command:

composer require darkaonline/l5-swagger

3. Configure Swagger PHP

After the installation is complete, we need to add the Swagger service provider to the Laravel configuration file. Open the config/app.php file, find the providers array, and add the following configuration:

`
'providers' => [

...
DarkaonlineL5SwaggerL5SwaggerServiceProvider::class,

],

'aliases ' => [

...
'Swagger' => DarkaonlineL5SwaggerFacadesSwaggerL5::class,

]
`

After completing the configuration, run the following command to publish swagger's configuration files, views, routing and other files:

php artisan vendor:publish --provider "L5SwaggerL5SwaggerServiceProvider"

4. Writing Swagger annotations

Now, we can start writing Swagger annotations. Swagger annotations are to add some specific statements to the code comments to tell the Swagger tool the parameters, return values, request methods, routing addresses and other information of the API.

Here we take the basic Api interface in Laravel as an example. We add Swagger annotations to our code. The sample code is as follows:

`
/**

• @SWGGet(
• path="/api/users/{id}",
• summary="Get user information",
• tags={"User Management"},
• @SWGParameter(
• name="id",
• in="path",
• required =true,
• type="integer",
• description="User ID"
• ),
• @SWGResponse(
• response=200,
• description="Operation successful",
• @SWGSchema(
• type="object",
• @SWGProperty(
• property="code",
• type="integer",
• format="int64",
• description="return code"
• ),
• @SWGProperty(
• property="data",
• type="object",
• description="User information content",
• @SWGProperty(
• property="id",
• type="integer",
• format="int64",
• description="User ID"
• ),
• @SWGProperty(
• property="name",
• type="string",
• description="User name"
• ),
• @SWGProperty(
• property="age",
• type="integer" ,
• format="int32",
• description="User age"
• )
• )
• )
• ),
• @SWGResponse(response=404, description="Non-existent user information"),
• @SWGResponse(response=500, description="Server internal error")
• )
  */

public function getUserInfo($id)
{

// 根据ID获取用户信息

}
`

We use the @SWGGet annotation above the code comment to describe The request method and routing address of the interface are added, and annotations such as summary, tags, parameters, and response are added to tell the Swagger tool more details about the interface.

5. Generate Swagger documentation

After completing the writing of Swagger annotations, we can generate Swagger API documentation. Open the terminal, enter the Laravel project directory, and enter the following command to generate the document:

php artisan l5-swagger:generate

After execution, the Swagger API document will be automatically generated, which can be generated through the browser Visit http://your_host/api/documentation to view the documentation. This page shows all our API interfaces, including request methods, parameters, return results and other details.

6. Testing the API interface

After completing the writing and display of the API document, we also need to test the API interface. In Swagger's API documentation, we can test an API interface by clicking the "Try it out" button. Here, we can manually enter the request parameters, and then click the "Execute" button to make the request. Swagger will automatically initiate a request to the server and display the response results. In this way, we can test the API interface through the Swagger tool.

Summary

Using Swagger PHP and Laravel integration, you can easily write perfect API interface documents and test the interface. In practical applications, the Swagger tool can greatly improve development efficiency and reduce the occurrence of errors. It is recommended that developers adopt the Swagger tool as soon as possible to improve the management and maintenance of API interfaces, thereby improving the reliability and stability of applications.
