+## 如何使用 EasyWeChat
+
+`EasyWeChat` 是为 `PHP-FPM` 架构设计的，所以在某些地方需要修改下才能在 Hyperf 下使用。下面我们以支付回调为例进行讲解。
+
+1. `EasyWeChat` 中自带了 `XML` 解析，所以我们获取到原始 `XML` 即可。
+
+```php
+$xml = $this->request->getBody()->getContents();
+```
+
+2. 将 XML 数据放到 `EasyWeChat` 的 `Request` 中。
+
+```php
+<?php
+use Symfony\Component\HttpFoundation\Request;
+
+$get = $this->request->getQueryParams();
+$post = $this->request->getParsedBody();
+$cookie = $this->request->getCookieParams();
+$files = $this->request->getUploadedFiles();
+$server = $this->request->getServerParams();
+$xml = $this->request->getBody()->getContents();
+
+$app['request'] = new Request($get,$post,[],$cookie,$files,$server,$xml);
+
+// Do something...
+```
+
+## 如何替换缓存
+
+`EasyWeChat` 默认使用 `文件缓存`，而现实场景是 `Redis` 缓存居多，所以这里可以替换成 `Hyperf` 提供的 `hyperf/cache` 缓存组件，如您当前没有安装该组件，请执行 `composer require hyperf/cache` 引入，使用示例如下：
+
+```php
+<?php
+use Hyperf\Cache\CacheInterface;
+use Hyperf\Utils\ApplicationContext;
+use EasyWeChat\Factory;
+
+$app = Factory::miniProgram([]);
+$app['cache'] = ApplicationContext::getContainer()->get(CacheInterface::class);
+
+```
