初步定位是没有传 out_refund_no （ 商户退款单号） 参数

找到原因了，请求的时候没有传CURLOPT_SSLCERT，CURLOPT_SSLKEY。当然out_refund_no这个参数还是要传的。
我测试的时候修改了EasyWeChat\Core\Http的post方法后申请退款成功。 看看这个这两个参数怎么传吧。😄

 public function post($url, $options = [])
    {
        $key = is_array($options) ? 'form_params' : 'body';
        return $this->request($url, 'POST', [$key => $options ,'cert'=>'/var/sites/cert.pem' , 'ssl_key'=>'/var/sites/key.pem']);
    }
