XMLRPC/mw_newMediaObject – Large files give request status of 0

  • I am using the Blogger APIs via xmlrpc.php to try to post files to my blog via a widget I’ve written. Basically, you drag & drop a file, and it posts to the blog. I send an XMLHttpRequest calling metaWeblog.newMediaObject, sending my file as a base64-encoded string. This works fine for small files such as images, and even smaller videos. But I’ve run into problems when uploading large video files (5-10MB in size).

    I’ve traced this down, and the file gets successfully written to the server, but for some reason the XMLHttpRequest status is 0 instead of the expected 200.

    I’ve spent 3 days tweaking server settings, and have increased all the timeouts, execution time, memory limits, size limits, etc in PHP and Apache, and none of that helped. Like I said, the file successfully saves to the server, so I know it works, but why won’t XMLHttpRequest return the proper status of 200?

    I’ve been beating my head against this wall for 3 days, so any help/advice would be greatly appreciated. Thanks!

    To elaborate, here is the XMLHttpRequest response I am expecting. This is from a smaller file (500k):

    <?xml version="1.0"?>
<methodResponse>
  <params>
    <param>
      <value>
        <struct>
<member><name>file</name><value><string>mvi-9148.avi</string></value></member>
<member><name>url</name><value><string>https://www.mydomain.com/wp-content/uploads/2008/06/mvi-91482.avi</string></value></member>
<member><name>type</name><value><string>video/avi</string></value></member>
        </struct>
      </value>
    </param>
  </params>
</methodResponse>

    But when I send a larger file (5-10MB), I don’t get any XMLHttpRequest response at all, even though the file is successfully uploaded and saved to the server. When I check XMLHttpRequest.status in my app, it is set to 0.

    Does the metaWeblog.newMediaObject return any data when this happens? Normally you’d get an XML-RPC response with file, URL and type data.

    Any chance your Javascript XHR code is timing out?

    That was it!! I’m using Konfabulator for my widget, and the default XMLHttpRequest.timeout is only 60 seconds. I upped this to 4 minutes and now the large files are successfully posting. I don’t know why I didn’t think of that… probably because my brain has turned to jello after 3 days on this. Thanks so much. ??
