ここで得たalbum id を使って、そのアルバムに画像を追加したいとします。
bloggerに執筆するときにはそれらをひとまとまりにしたい
というのが良くある考え方だと思います。
その時、
get-direct-url-in-picasa.pyをつかって、picasa上にその画像の有無を調べます。
画像があれば、picasa上のファイルへのdirect linkが得られるはずです。
もしpicasa上にその画像が無いと判断したら、
upload-image-to-blogger-in-picasa.pyをつかって、
最初に得たalbum id を指定して、画像をアップロードします。
そしてその画像のpicasa上でのdirect linkをget-direct-url-in-picasa.pyで得ます。
まずはget-direct-url-in-picasa.py の内容です。
#!/usr/bin/python2.5
# return the direct link (URL) of picture in picasa.
import sys # for argv
import gdata.photos.service
import gdata.media
import gdata.geo
argvs = sys.argv
argc = len(argvs)
if (argc != 3 ):
print 'Usage: # python %s AlbumName FileName' % argvs[0]
quit()
albumname = argvs[1]
filename = argvs[2]
album_id="1234567890123456789" # the albm_id fo "Chemical-X" was given by get_albumid.py
gd_client = gdata.photos.service.PhotosService()
gd_client.email = 'changeme@gmail.com' # Set your Picasaweb e-mail address...
gd_client.password = 'secret word' # ... and password
gd_client.source = 'api-sample-google-com'
gd_client.ProgrammaticLogin()
album_url = '/data/feed/api/user/%s/albumid/%s' % ('default', album_id)
photos = gd_client.GetFeed('/data/feed/api/user/%s/albumid/%s?kind=photo' % ('default', album_id))
for photo in photos.entry:
if photo.title.text == filename :
print photo.content.src,
続いて、upload-image-to-blogger-in-picasa.py の内容です。
#!/usr/bin/python2.5
# return the direct link (URL) of picture in picasa.
import sys # for argv
import gdata.photos.service
import gdata.media
import gdata.geo
argvs = sys.argv
argc = len(argvs)
if (argc != 2 ):
print 'Usage: # python %s FileName' % argvs[0]
quit()
filename = argvs[1]
gd_client = gdata.photos.service.PhotosService()
gd_client.email = 'changeme@gmail.com' # Set your Picasaweb e-mail address...
gd_client.password = 'secret password' # ... and password
gd_client.source = 'upload-image-to-blogger-in-picasa'
gd_client.ProgrammaticLogin()
album_id="1234567890123456789" # the albm_id fo "Chemical-X" was given by get_albumid.py
album_url = '/data/feed/api/user/%s/albumid/%s' % ('default', album_id)
photo = gd_client.InsertPhotoSimple(album_url, filename, filename, filename, content_type='image/png')
print photo.content.src,
これで、画像がもともとpicasa上にあってもなくてもどちらの場合だったとしても、
処理後には、picasa上のurlを取得できたことになります。
それを使って、org2blogger.elでは、エクスポートしたhtml無いでの画像リンク先を変更するという作業を行います。

置換し終わったhtmlをorg-googlecl.elのorg-googlecl-blog関数を使ってblogger.comへ投稿します。
org-modeで書いたテキスト内で、
M-x org-googlecl-blog
してみてください。
世界が変わって見えましたか?
