ElementTree.py not well-formed (invalid token)

Error:

rss = fromstring(r.xml) File "/base/python_runtime/python_dist/lib/python2.5/xml/etree/ElementTree.py", line 963, in XML parser.feed(text) File "/base/python_runtime/python_dist/lib/python2.5/xml/etree/ElementTree.py", line 1245, in feed self._parser.Parse(data, 0) ExpatError: not well-formed (invalid token): line 1, column 149

Fix
       r.xml = r.xml.replace("&type", "&type")

Post facebook photo by Command line

access_token に対応したfacebook application名のアルバムに保存される
公開するためには手動で承認作業が必要。
　

fb_image_upload.sh

#!/bin/bash

if [ "$#" -eq 0 ];then
 echo "Do not get image. "
 else
 echo " Get image. "$1
 /opt/local/bin/python2.5 get_image.py $1
fi

msg="test"
caption="message="$msg""
token=`cat .fb_access_token`
echo $caption
echo $token

echo `curl -F "access_token="$token"" -F "source=@"dummy.jpg"" -F "$caption" https://graph.facebook.com/me/photos`

alubm ID によりアルバムを指定して post することもできるが、この場合も公開には承認作業が必要。

echo `curl -F "access_token="$token"" -F "source=@"dummy.jpg"" -F "$caption" https://graph.facebook.com/10150411507966880/photos`

　

アプリケーションで自動作成されるアルバムには１０００枚まで写真が保存できるみたいです。

https://graph.facebook.com/ALBUM_ID/photos - The photo will be published to a specific, existing photo album, represented by the ALBUM_ID. Regular albums have a size limit of 200 photos. Default application albums have a size limit of 1000 photos.

Get facebook albums by commad line

ポイント

1. GAEで利用する python2.5 でなくpython2.6以上を利用
   json や urlparse.parse_qs でエラーとなる
   AttributeError: 'module' object has no attribute 'parse_qs'
2. 'scope':'read_stream,user_photos'
3. １度で２０件づつしか取得できないので paging が必要となる
   また、先頭の１行のデータは重複する(?)。
4. http://127.0.0.1:8080/ を登録
   
   
   　

5. token が expire している場合は以下のエラーとなるため
   urllib2.HTTPError: HTTP Error 400: Bad Request
   $ rm .fb_access_token
