Qiniu uploaded a picture with the same name, how to get a new link?

Using Qiniu's private Bucket storage, PHP server, set insertOnly to 0, you can overwrite old pictures
Uploaded code:

<code>    
    $key="123.jpg";
    $policy=array('insertOnly'=> 0);
    $token = $this->auth->uploadToken($bucket,$key ,3600, $policy);
    // 构建 UploadManager 对象
    $uploadMgr = new UploadManager();
    $result = $uploadMgr -> putFile($token,$key,$path);
    return $result;
    </code>

After the upload is successful, this is how I get the image external link:

<code>    $baseUrl = $bucketDomain.'/'.$key;
    $authUrl = $this->auth->privateDownloadUrl($baseUrl);
    return $authUrl;</code>

Then return to the client tag and update the IMG's src using JS
But I found that the old image is still displayed. How can I solve this problem? Thank you very much!

Qiniu Cloud does caching, and the platform management provides a way to refresh the data of the specified URI to obtain the latest data.
I think you should generate a $key by yourself and add some time to generate random parameters (if you don’t specify the key, Qiniu will randomly hash the file name and store it)
