There is an error in the callback for uploading pictures. The same callback function is just changed to a different domain name. The online server is OK, but the test server reports an error and returns 579. What's going on?

1. Problem description:
When Qiniu uploads pictures, the same callback function returns an error on the test server and reports a 579 error. However, it can be uploaded to the online server, and there was no problem uploading to the test server before. After a while, there is an error. Problem.

2. Return to the function:
public function qiniuUploadCallback(){

<code>    $data['key'] = $_POST['filetype'];
    $data['name'] = $_POST['fname'];
    $data['size'] = $_POST['fsize'];
    $data['module'] = $_POST['module'];
    $data['savename'] = $_POST['key'];
    $data['create_time'] = time();
    $data['width'] = $_POST['w'];
    $data['height'] = $_POST['h'];
    $data['type'] = '';
    $data['status'] = 1;
    $data['record_id'] = $data['user_id'] = 0;

    $id = M('Attach')->add($data);

    $this->ajaxReturn(array('id'=>$id,'w'=>$_POST['w'],'h'=>$_POST['h'],'key'=>$_POST['key'],'fsize'=>$_POST['fsize']));
}</code>

Callback 579 means the upload was successful but the callback failed. Generally, there are the following situations:
1. Network problem.
2. The server has blocked Qiniu.
When troubleshooting, first confirm whether the server has blocked Qiniu’s IP. If there is no problem, you can send the reqID and problem description to support@qiniu.com and let Qiniu technical support take a look.
