#EasyWechat

EasyWeChat is an open source WeChat SDK (not WeChat official SDK).

If you are using Swoole 4.7.0 and above, and have the native curl option turned on, you may not follow this document.

Because the component uses Curl by default, we need to modify the corresponding GuzzleClient as a coroutine client, or modify the constant SWOOLE_HOOK_FLAGS

replace Handler

The following takes the public account as an example,

php
<?php

use Hyperf\Context\ApplicationContext;
use EasyWeChat\Factory;
use GuzzleHttp\Client;
use GuzzleHttp\HandlerStack;
use Hyperf\Guzzle\CoroutineHandler;

$container = ApplicationContext::getContainer();

$app = Factory::officialAccount($config);
$handler = new CoroutineHandler();

// Set HttpClient, some interfaces use http_client directly.
$config = $app['config']->get('http', []);
$config['handler'] = $stack = HandlerStack::create($handler);
$app->rebind('http_client', new Client($config));

// Some interfaces will reset the Handler according to guzzle_handler when requesting data
$app['guzzle_handler'] = $handler;

// If you are using OfficialAccount, you also need to set the following parameters
$app->oauth->setGuzzleOptions([
    'http_errors' => false,
    'handler' => $stack,
]);

Modify SWOOLE_HOOK_FLAGS

Reference SWOOLE_HOOK_FLAGS

How to use EasyWeChat

EasyWeChat is designed for PHP-FPM architecture, so it needs to be modified in some places to be used under Hyperf. Let's take the payment callback as an example to explain.

  1. EasyWeChat comes with XML parsing, so we can get the original XML.
php
$xml = $this->request->getBody()->getContents();
  1. Put XML data into Request of EasyWeChat.
php
<?php
use Symfony\Component\HttpFoundation\HeaderBag;
use Symfony\Component\HttpFoundation\Request;

$get = $this->request->getQueryParams();
$post = $this->request->getParsedBody();
$cookie = $this->request->getCookieParams();
$uploadFiles = $this->request->getUploadedFiles() ?? [];
$server = $this->request->getServerParams();
$xml = $this->request->getBody()->getContents();
$files = [];
/** @var \Hyperf\HttpMessage\Upload\UploadedFile $v */
foreach ($uploadFiles as $k => $v) {
    $files[$k] = $v->toArray();
}
$request = new Request($get, $post, [], $cookie, $files, $server, $xml);
$request->headers = new HeaderBag($this->request->getHeaders());
$app->rebind('request', $request);
// Do something...
  1. Server Configuration

If you need to use the server configuration function of the WeChat public platform, you can use the following code.

The following $response is Symfony\Component\HttpFoundation\Response not Hyperf\HttpMessage\Server\Response So just return the Body content directly to pass WeChat verification.

php
$response = $app->server->serve();

return $response->getContent();

How to replace the cache

EasyWeChat uses file cache by default, but the actual scenario is that Redis cache is mostly used, so this can be replaced with the hyperf/cache cache component provided by Hyperf, if you do not currently install this component, please execute composer Introduced by require hyperf/cache, the usage example is as follows:

php
<?php
use Psr\SimpleCache\CacheInterface;
use Hyperf\Context\ApplicationContext;
use EasyWeChat\Factory;

$app = Factory::miniProgram([]);
$app['cache'] = ApplicationContext::getContainer()->get(CacheInterface::class);
