HTTP Health Check

HTTP Health Check is a simple HTTP health check written in PHP built on top of Guzzle.

• Easy way to check HTTP services status by status code and body content from your PHP application
• Grant finite HTTP request timeout (Guzzle does not)
• Positive behavior by default. If no conditions are provided, the health will be consider healthy as soon as the request can be made successfully - no connectivity issues

Installation

Install the latest version through Composer:

$ composer require jesugmz/http-health-check

Usage

HTTP Health Check will do a GET request to the given endpoint URL and can check the following conditions in the response:

• HTTP status code: expressed as status_code_equals_to
• Body content: plain text that appears in the body response and is expressed as body_contains

use HttpHealthCheck\HttpHealthCheck;

$endpointUrl = 'https://github.com/jesuGMZ/';
$conditions = [
    'status_code_equals_to' => 200,
    'body_contains'         => 'jesuGMZ',
];

$check = new HttpHealthCheck($endpointUrl, $conditions);

var_dump($check->isHealthy());

It allows also Guzzle Request Options parameters:

use HttpHealthCheck\HttpHealthCheck;

$endpointUrl = 'https://mdn.github.io/learning-area/javascript/oojs/json/superheroes.json';
$conditions = [
    'status_code_equals_to' => 200,
    'body_contains'         => 'Super hero squad',
];
$options = [
    'headers' => [
        'User-Agent' => 'My custom user agent',
        'Accept'     => 'application/json',
    ]
];

$check = new HttpHealthCheck($endpointUrl, $conditions, $options);

var_dump($check->isHealthy());
