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
