代码：

$obj = new \CURLFile(realpath($filePath));

$obj->setMimeType("image/jpeg");

$file['media'] = $obj;

$url = "https://api.weixin.qq.com/wxa/img_sec_check?access_token=".$accessToken;

$info = $this->http_request($url,$file);

$info =  json_decode($info,true);

dump($info);

    //HTTP请求（支持HTTP/HTTPS，支持GET/POST）

    private function http_request($url, $data = null)

    {

        $curl = curl_init();

//        curl_setopt($curl, CURLOPT_HTTPHEADER, array('Content-Type: multipart/form-data'));

        curl_setopt($curl, CURLOPT_URL, $url);

        curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);

        curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE);

        if (!empty($data)) {

            curl_setopt($curl, CURLOPT_POST, TRUE);

            curl_setopt($curl, CURLOPT_POSTFIELDS,$data);

        }

        curl_setopt($curl, CURLOPT_RETURNTRANSFER, TRUE);

        $output = curl_exec($curl);

        curl_close($curl);

        return $output;

    }
