Security cam blog posts on Tumblr
Conclusions and Future
Now, the Tumblr features come into play. Line 31 reads the YAML file with the tokens, and line 33 creates a new object of the WWW::Tumblr type. Drawing on the Tumblr API, line 43 then retrieves the details of the previously defined test blog (schtonk.tumblr.com
) and the post()
method sends the image file content to the Tumblr server, specifying the type as photo
. Then, $post
indicates success with a true value. If you then launch the script by typing ./tumblr-post
, the response is the ID of the newly created blog entry:
I have published post id: 63791478637
Unfortunately, the API provides no way to attach an image caption. This method currently seems to work only via a browser interface that allows HTML pages with embedded photos. Theoretically, however, the script could upload text and reference the images on a different server. For the surveillance photos, however, it is more convenient for me to store the images on Tumblr.
A viable alternative would be a caption in the image itself, as presented in last month's Perl column using the CPAN Imager module. In this way you could add brief texts to the image – for example, the current outdoor temperature.
