The function, basically gets the 'cid' (Content ID) for the image. If you refer to the xep_0231 plugin of the sleekxmpp library, you will find the set_bob function which does just that.
When sent, the image source (src) will reflect said cid (in the following format - cid:sha1+(generated alphanumeric)@bob.xmpp.org) which can be used by the recipient to retrieve the cached data - in this case the image.
However, it would be important to note that certain clients and server do not support html which will thus lead to inability to deliver said image.
More information of the XEP-0231 plugin can be found at http://xmpp.org/extensions/xep-0231.html
Hi,
Function b.send_image_bob('someone@example.com', 'image.png') doesn't work with python3. We obtain this error:
m['html']['body'] = '<img src="cid:%s" />' % cid
TypeError: 'str' object does not support item assignment
Do you know why ?
@sbonnegent m['html'] is '' unless you do self.register_plugin('xep_0071') in __init__
Oh, it works now, thank you @s-nt-s ! I didn't see it in doc.
there are any android client that supports BOB?
is it possible to send image as an attachment ? because when i try 'sending image with OOB' jabber receiver receives the image but its coming as an unsupported image format .
How is the working of function 'send_image_bob' and what is the object cid it displays some jabber website name.Can you please explain what is happening in this function
