最后更新时间：2020-10-24 13:29:23

hyperf swoole easywechat

##  安装 EasyWechat组件
```
1. composer require overtrue/easywechat
2. 在APP\Factory目录新建立一个WechatFactory.php(见配置)
3. 在config/autoload里新加一个wechat.php(见配置)
```
## 配置

###wechat.php 以小程序为例

多小程序配置把各自的小程序账号分别存入进去

### WechatFactory.php 代码贴图有点长直接贴代码吧
```

## 如何调用
```
<?php
declare(strict_types = 1);

namespace App\Controller;
use Hyperf\HttpServer\Annotation\Controller;
use Hyperf\HttpServer\Annotation\RequestMapping;

/**
 * Class TestController
 * @Controller(prefix="wechat")
 */
class WechatController extends AbstractController
{
    /**
     * @\Hyperf\Di\Annotation\Inject()
     * @var \App\Factory\WechatFactory
     */
    protected $wechatFactory;
    /**
     * @RequestMapping(path="session", methods="get,post")
     */
    public function session()
    {
        $code    = $this->request->input('code');
        $session = $this->wechatFactory->auth->session($code);
        dump($session);
    }
}
```

## 效果
