I want to download attachments from a vbulletin forum with login. It always gives me an error about unspecified length. In the thread itself only thumbnails are displayed, but i want the full resolution which is in the attachments. I am targeting only the *.jpg, not the rest of the forum. The url looks something like this: http://www.page.com/attachment.php?attachmentid=1234567&d=1234567890 (I think both numbers "attachmentid" and "d" are random and independent from each other.) When I try mirroring the whole page everything works except the attachments(thumbnails are downloaded). Any ideas how I can solve this issue?
Cheers
PS: Httracker brings me to the same problem, alternative solutions welcome as well :)
As you mentioned about "download attachments from a vbulletin forum with login", make sure you have done the login part. So the steps will be as follows.
1) Make the login using wget, and store the cookie into a txt file. Parameter can be --save-cookies
2) Now call the attachment download portion using another wget call and use the cookie.txt(of step 1) with this call. The parameter can be --load-cookies
More detailed about the wget parameters can be found from here.
Both attachmentid and Id can not be random at the same time. Otherwise the forum can not recognize at which attachment you are focusing on.
