Then recognize the QR code.
I use PHP’s curl post to upload images, but it always displays null. Did I miss any parameters?

<code>public function index(){

     $url='http://upload.api.cli.im/upload.php?kid=cliim';
     $r_file='/test.jpg';
     $res=$this->upload_file($url,$r_file);
     var_dump($res);
}

  private  function upload_file($url,$r_file)
     {
        $file = array("fax_file"=>'@'.$r_file,'type'=>'image/jpeg');//文件路径，前面要加@，表明是文件上传.
        $curl = curl_init();
        curl_setopt($curl, CURLOPT_URL,$url);
        curl_setopt($curl,CURLOPT_POST,1);
        curl_setopt($curl,CURLOPT_POSTFIELDS,$file);
        curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($curl, CURLOPT_HEADER, 0);
        $result = curl_exec($curl);  //$result 获取页面信息 
        curl_close($curl);
        echo $result ; //输出 页面结果
   }</code>

The $res returned by the above code will always be null. Normally, it should return an image address belonging to the fodder
