1. Decide whether to retry when guzzle response is not OK

A service of 100 percent availability does not exist. So we must decide when to retry when a failure occurs.

Guzzle is a great HTTP client for PHP users and it provides a flexible mechanism to customize your request. When deciding when to retry, just tell guzzle whether to retry depending on response and when to retry after the 'failed' request.

2. Log both request and response (only when their bodies are readable for human)

3. Define your base_uri and pattern once with '{}' marks and UriReplacer will do the rest.

Installation

composer require subtlephp/middlewares

Prerequisites

Logger middleware depends on 2 constants, REQUEST_ID and LOG_DIR, but they are not must. REQUEST_LOG equals '' and LOG_DIR equals __DIR__ by default.

Usage

<?php

use GuzzleHttp\HandlerStack;
use GuzzleHttp\Middleware;
use SubtlePHP\Middlewares\Guzzle\Retry;
use SubtlePHP\Middlewares\Guzzle\UriReplacer;
use SubtlePHP\Middlewares\Guzzle\Logger;
use GuzzleHttp\Client;
use GuzzleHttp\Psr7\Request;

$handlerStack = new HandlerStack();
$maxRetryTimes = 2;
$delay = 100;

$retryMiddleware = Middleware::retry(Retry::decider($maxRetryTimes), Retry::delay($delay));
$middlewares = [
    new UriReplacer(),
    new Logger(),
    $retryMiddleware,
];
$handlerStack->push($retryMiddleware);
$base_uri = 'http://gank.io';
$pattern = '/api/data/Android/{per_page}/{page}';
$client = new Client(['base_uri' => $base_uri, 'handler' => $handlerStack, [
    'attributes' => [
        'page' => 1,
        'per_page' => 10,
    ],
]]);
$request = new Request('GET', $pattern);
$response = $client->send($request);
