PHP implements open source API management platform system

With the continuous development of Web services, Web API has become an important part of the Web 2.0 era. Web API provides many functions and interfaces for applications, allowing us to build various applications more simply and conveniently. However, managing and maintaining a large number of APIs can be a headache. Therefore, an open source API management platform system is very necessary.

This article will introduce how to use PHP to implement an open source API management platform system.

Environment preparation

In order to run our open source API management platform system, we need the following environments:

1. PHP
2. MySQL
3. Apache/Nginx

Of course, you can also use other web servers instead of Apache or Nginx.

System Framework

We use the PHP framework Laravel to build our open source API management platform system. Laravel is a popular PHP framework that is beautifully designed and easy to use and maintain.

Install Laravel

Use the following command to install the latest version of Laravel:

composer create-project --prefer-dist laravel/laravel api-manager

This command will create a new project called api-manager in the current directory and automatically install Laravel and its related dependencies.

Create Database

We need to create a database in MySQL and associate it with our application. We can use the following command to create a new database in MySQL:

CREATE DATABASE api_manager;

Update database configuration information

Open the .env file of the api-manager project and change The following information is updated with your MySQL connection information:

DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=api_manager
DB_USERNAME=root
DB_PASSWORD=

Install and configure Swagger

Swagger is a popular API documentation tool that can help us better organize and display API documentation. We can install Swagger using the following command:

composer require "darkaonline/swagger-lume:5.8.*"

After successfully installing Swagger, we need to add the following in the config/app.php file Content:

// Register Swagger Provider
$app->register(SwaggerLumeServiceProvider::class);

// Register Publish
$app->configure(' swagger-lume');
$app->register(SwaggerLumeServiceProvider::class);

// Publish config, views and assets
$this->publishes([

__DIR__.'/../config/swagger-lume.php' => config_path('swagger-lume.php'),

], 'config');

Add the Swagger view to the application's routes/web.php file:

$router->get('/', function () use ($router) {

return view('swagger');

});

This will display the Swagger documentation under our application root path.

Create API Controller

We need to create a controller in the api-manager application to handle API requests. We can create a controller using the following command:

php artisan make:controller ApiController

This will create a new controller file named ApiController.php in the app/Http/Controllers directory .

In the ApiController.php file, add the following code:

namespace AppHttpControllers;

use IlluminateHttpRequest;

class ApiController extends Controller
{

public function list()
{
    return response()->json(['status' => 'success', 'message' => 'API list']);
}

public function get($id)
{
    return response()->json(['status' => 'success', 'message' => 'API '.$id]);
}

public function create(Request $request)
{
    $name = $request->input('name');
    $url = $request->input('url');

    return response()->json(['status' => 'success', 'message' => 'API '.$name.' created']);
}

public function update(Request $request, $id)
{
    $name = $request->input('name');
    $url = $request->input('url');

    return response()->json(['status' => 'success', 'message' => 'API '.$id.' updated']);
}

public function delete($id)
{
    return response()->json(['status' => 'success', 'message' => 'API '.$id.' deleted']);
}

}

The above code defines the common operation methods of API for us: list, get, create, update, delete.

API routing configuration

We need to add the following code to the routes/api.php file:

$router->group(['prefix' => ' api'], function () use ($router) {

// List APIs
$router->get('list', 'ApiController@list');

// Get API
$router->get('get/{id}', 'ApiController@get');

// Create API
$router->post('create', 'ApiController@create');

// Update API
$router->put('update/{id}', 'ApiController@update');

// Delete API
$router->delete('delete/{id}', 'ApiController@delete');

});

This will define the request routing for each API for us.

Testing API

We can use tools such as Postman to test our API. In Postman, you can use the following request URL to test the API:

GET http://localhost:8000/api/list
GET http://localhost:8000/api/get/1
POST http://localhost:8000/api/create
PUT http://localhost:8000/api/update/1
DELETE http://localhost:8000/api/delete/1

Finally, start the local server and execute the following command:

php artisan serve

Now, we can open http://localhost:8000/ in the browser to view our Open source API management platform system. At the same time, we can also access our API at http://localhost:8000/api. In Swagger, we can view the documentation of the API and test various functions of the API.

Conclusion

It is not difficult to implement an open source API management platform system with PHP. Using the Laravel framework and Swagger tools, we can build a complete API management platform system very easily.

Mastering the open source API management platform system will lead you to open up a new path and make your web application world more interesting and exciting.
