微信公众号或小程序的appid 和 secret

use EasyWeChat\Factory;

$config = [
    'app_id' => '',
    'secret' => '',

    // 指定 API 调用返回结果的类型：array(default)/collection/object/raw/自定义类名
    'response_type' => 'array',

    //...
];

$app = Factory::officialAccount($config);公众号

$app = Factory::miniProgram($config);小程序
 $app->customer_service->message($message)->to($openId)->send(); 小程序发送

具体代码的实现

use EasyWeChat\Factory;
use EasyWeChat\Kernel\Messages\Text;
use EasyWeChat\Kernel\Messages\Image;
use EasyWeChat\Kernel\Messages\Raw;
public function replyWxContent()
{
    $config = config('account.easywechat');
    $app = Factory::miniProgram($config);
    $app->server->push(function ($message) use ($app) {

    });
    $response = $app->server->serve();
    $response->send();

上传图片到微信服务器

public function getMediaId($url = '')
    {
        if (!empty($url)) {
            $cache_key = 'get_media_id_' . $url;
            $media_id = cache($cache_key);
            if ($media_id === false) {
                $config = config('account.easywechat');
                $app = Factory::miniProgram($config);;
                $imagePath = $this->downloadImage($url);
                $data = [
                    'midia' => realpath('.' . $imagePath),
                ];
                try {
                    $result = $app->media->uploadImage($data['midia']);
                    if ($result['media_id']) {
                        $media_id = $result['media_id'];
                        cache($cache_key, $media_id, 60 * 60 * 48);
                    }
                } catch (\Exception $e) {
                    model('Common/DebugLog')->addLog($e->getMessage(), 'error');
                }

            }
            return $media_id;
        }
        return false;
    }

    public function downloadImage($url)
    {
        set_time_limit(0);
        $saveDir = '/uploads/' . date('Ymd');
        if (!is_dir("." . $saveDir)) {
            mkdir("." . $saveDir, 0777, true);
        }
        $saveSrc = $saveDir . '/' . md5($url) . ".jpg";
        try {
            $res = file_get_contents($url);
            if (false === $res) {
                return '';
            }
            file_put_contents("." . $saveSrc, $res);
            return $saveSrc;
        } catch (\Exception $e) {
            return '';
        }
    }

其中回复链接消息，easywechat 不支持，使用自定义Raw()方法

raw()需要传入的是json的数据格式
可以使用raw 创建想要发送的数据类型，具体需要的数据字段参考微信的官方文档
