README

Abigail is the fork from marcj/php-rest-service, which is a simple and fast PHP microservice framework for server side RESTful APIs.

Features

Easy to use syntax
Regular Expression support
Error handling through PHP Exceptions
Parameter validation through PHP function signature
Can return a summary of all routes or one route through OPTIONS method based on PHPDoc (if OPTIONS is not overridden)
Support of GET, POST, PUT, DELETE, PATCH, HEAD and OPTIONS
Suppress the HTTP status code with ?_suppress_status_code=1 (for clients that have troubles with that)
Supports ?_method=httpMethod as addition to the actual HTTP method.
With auto-generation through PHP's reflection

Installation

https://packagist.org/packages/starinc/abigail.
More information available under https://packagist.org/.

Create a composer.json:

{
  "require": {
    "starinc/abigail": "*"
  }
}

then run

$ wget https://getcomposer.org/composer.phar
$ php composer.phar install

After the installation, you need to include the vendor/autoload.php to make the class in your script available.

include 'vendor/autoload.php';

Requirements

PHP 7.4 and above.
PHPUnit to execute the test suite.
Setup PATH_INFO in mod_rewrite (.htaccess) or other webserver configuration

Example config

Apache webserver

#.htaccess
RewriteEngine On

RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule (.+) index.php/$1 [L,QSA]

Nginx webserver

// edit virtualhost /etc/nginx/conf.d/name_virtualhost_file
server {
 .. something params ...
 location / {
  include fastcgi_params;
     
  fastcgi_pass unix:/var/run/php-fpm.sock;
  fastcgi_param SCRIPT_FILENAME $document_root/index.php;
 }
}

// and add line to /etc/nginx/fastcgi_params
fastcgi_param PATH_INFO $fastcgi_script_name;

Usage Demo

Way 1. The dirty & fast

use Abigail\Server;

Server::create('/')
    ->addGetRoute('test', function(){
        return 'Yay!';
    })
    ->addGetRoute('foo/(.*)', function($bar){
        return $bar;
    })
    ->addPostRoute('foo', function($field1, $field2) {
      // do stuff with $field1, $field2, etc.
      // or you can directly get them with $_POST['field1'].
    })
->run();

Way 2. Auto-Collection

index.php:

use Abigail\Server;

Server::create('/admin', 'myRestApi\Admin')
    ->collectRoutes()
->run();

MyRestApi/Admin.php:

namespace MyRestApi;

class Admin {

    /**
    * Checks if a user is logged in.
    *
    * @return boolean
    */
    public function getLoggedIn(){
        return $this->getContainer('auth')->isLoggedIn();
    }

    /**
    * @param string $username
    * @param string $password
    * @return boolean
    */
    public function postLogin($username, $password){
        return $this->getContainer('auth')->doLogin($username, $password);
    }

    /**
     * @param string $server
     * @url stats/([0-9]+)
     * @url stats
     * @return string
     */
    public function getStats($server = '1'){
        return $this->getServerStats($server);
    }

}

Generates following entry points:

    + GET  /admin/logged-in
    + POST /admin/login?username=&password=
    + GET  /admin/stats/([0-9]+)
    + GET  /admin/stats

Way 3. Custom rules with controller

index.php:

use Abigail\Server;

Server::create('/admin', new MyRestApi\Admin) //base entry points `/admin`
    ->setDebugMode(true) //prints the debug trace, line number and file if an exception has been thrown.

    ->addGetRoute('login', 'doLogin') // => /admin/login
    ->addGetRoute('logout', 'doLogout') // => /admin/logout

    ->addGetRoute('page', 'getPages')
    ->addPutRoute('page', 'addPage')
    ->addGetRoute('page/([0-9]+)', 'getPage')
    ->addDeleteRoute('page/([0-9]+)', 'deletePage')
    ->addPostRoute('page/([0-9]+)', 'updatePage')

    ->addGetRoute('foo/bar/too', 'doFooBar')

    ->addSubController('tools', \RestApi\Tools) //adds a new sub entry point 'tools' => admin/tools
        ->addDeleteRoute('cache', 'clearCache')
        ->addGetRoute('rebuild-index', 'rebuildIndex')
    ->done()

->run();

MyRestApi/Admin.php:

namespace MyRestApi;

class Admin {
    public function login($username, $password){

        if (!$this->validLogin($username, $password))
            throw new InvalidLoginException('Login is invalid or no access.');

        return $this->getToken();

    }

    public function logout(){

        if (!$this->hasSession()){
            throw new NoCurrentSessionException('There is no current session.');
        }

        return $this->killSession();

    }

    public function getPage($id){
        //...
    }
}

namespace RestAPI;

class Tools {
    /**
    * Clears the cache of the app.
    *
    * @param boolean $withIndex If true, it clears the search index too.
    * @return boolean True if the cache has been cleared.
    */
    public function clearCache($withIndex = false){
        return true;
    }
}

Responses

The response body is always an array (JSON per default) containing a status code and the actual data. If an exception has been thrown, it contains the status 500, the exception class name as error, and the message as message.

Some examples:

+ GET admin/login?username=foo&password=bar
  =>
  {
     "status": "200",
     "data": true
  }

+ GET admin/login?username=foo&password=invalidPassword
  =>
  {
     "status": "500",
     "error": "InvalidLoginException",
     "message": "Login is invalid or no access"
  }

+ GET admin/login
  =>
  {
     "status: "400",
     "error": "MissingRequiredArgumentException",
     "message": "Argument 'username' is missing"
  }

+ GET admin/login?username=foo&password=invalidPassword
  With active debugMode we'll get:
  =>
  {
     "status": "500",
     "error": "InvalidLoginException",
     "message": "Login is invalid or no access",
     "line": 10,
     "file": "libs/RestAPI/Admin.class.php",
     "trace": <debugTrace>
  }

+ GET admin/tools/cache
  =>
  {
     "status": 200,
     "data": true
  }
