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;     } 任何图片及大小，接口返回的都是ok，麻烦大神们帮我看下问题出在哪儿 [图片]
