Feature request: Parse pasted URL for ID

[That-Dude]

I was wondering if it would be possible to paste magazine URL and have the ID extracted from.

[pietrop]

Apologies for late reply,

I suppose it might be possible, it would require grabbing the documentId element from the page, and set the variabledocument_id in the script equal to that. The rest should work pretty much the same.

if you are not familiar with at I sudgest looking at this tutorial on scraping http://ruby.bastardsbook.com/chapters/html-parsing/

if you want to try it out and do a pull request that could be an interesting feature to add.

also you might find this tutorial interesting/usefull http://pietropassarelli.com/issuu.html

ps: if you just want to get the issu magazine as pdf and not to bothered about the code or the implementation you can always use http://issuu-downloader.abuouday.com/ haven't tried it myself as wasn't a round at the time when I did this script but might be a good solution.

Hi Pietro

I ended up writing my own script to do this in bash, I just grabbed the
paged and parsed it for the document id and number of pages then downloaded
the images with curl.

Thanks for the good idea though, it really got me started.

Nice one, glad it all worked out!

is there a link to your script somewhere? I'd be curious to see how you implemented it in bash

[That-Dude]

Sure, see attached.

I should point a couple of things:

1. I'm a photographer not a developer, this script is probably far from
   optimal :-)
2. I've only tested it on Mac OSX, but I wrote it to be POSIX compliant so
   it should run just fine on any unix environment (it has no dependencies
   beyond what's installed by default)
3. I didn't publish it anywhere because I figured it would be trivial for
   ISSUU to change their protocol and prevent this from working
4. I think this falls into a legally gray area so you might want to check
   the law in your country

That's great Thanks Dan,
I don't see any attachment thou ...

[That-Dude]

Oh it was definitely there, maybe github strips it. Copy and paste.

#!/bin/bash
#Script to download from ISSUU.com using the magazine URL as an argument.
#Once complete, ZIP up images into CBZ file, readable by any comicbook
reader

if [[ $# -eq 0 ]] ; then
echo 'Need an issuu.com URL'
exit 0
fi

#Grab the magazine HTML page and save it to a file
curl -s -o targetmag.html $1

#Extract the unique docuement ID from the HTML file
x="$(grep -m1 -o 'documentId.{0,46}' targetmag.html)"
documentID=${x:11:45}
echo "Unique documentID = "$documentID

#Extract the document name
docuentNAME="$(grep -o "<title>[^<]*" targetmag.html | tail -c+8)"
printf "\n"
echo "Document name = "$docuentNAME

#Extract the page count
x="$(grep -o -m1 'pageCount.{0,5}' targetmag.html | tr -d ',')"
pagecount=${x:11}
echo "There are "$pagecount" pages."

pagenumber=1 #Start downloading at page 1
pagecount=$((pagecount+1))

mkdir "$docuentNAME"
cd "$docuentNAME"

while [ $pagenumber != $pagecount ]; do
filename='page_'$pagenumber".jpg"
linkurl="http://image.issuu.com/"$documentID"/jpg/page_"$pagenumber".jpg"
curl -s -o $filename $linkurl #Grab the JPG file
printf "."
pagenumber=$((pagenumber+1))
done

zip -q0 "$docuentNAME".cbz *.jpg
rm *.jpg
mv "$docuentNAME".cbz ../
cd ..
rmdir "$docuentNAME"
rm targetmag.html
printf "\ndone\n \n"
