Shindig を動かしてみる（PHP 版 Gadget Server）

Shindig を動かしてみるその２。久しぶりにレポジトリ見ると PHP 版の Gadget Server ができているようなので README 見ながら試してみます。

環境は前回と同じで、coLinux、Linux debian 2.6.17-co-0.8.0 #1 PREEMPT Sun Jul 8 14:00:12 CEST 2007 i686 GNU/Linux です。

Installing and Running The PHP Shindig Gadget Server
============================================

1) Make sure you have PHP 5.x installed and have the simplexml and json extentions enabled; It also
   requires apache with .htaccess and mod_rewrite support

2) Copy the files to your web root, and edit the config.php web_prefix and debug settings
   to your liking. Make sure that the features and javascript directories are also copied
   or edit your config.php to reflect their location.

3) Hit server at http:///gadgets/ifr?url=
   Example: http:///gadgets/ifr?url=http://www.labpixies.com/campaigns/todo/todo.xml
   Or hit the sample container at http:///gadgets/files/samplecontainer/samplecontainer.html

The PHP source of the gadget server resides in gadgets/src.

For more information, see http://incubator.apache.org/projects/shindig.html

というわけで、まずは必要なファイルをコピー。

[maihara@debian:~/work/shindig/php/gadgets] $ cp -R ../gadgets ~/public_html
[maihara@debian:~/work/shindig/php/gadgets] $ cp -R .htaccess ../../config ../../features ../../javascript ~/public_html/gadgets
[maihara@debian:~/work/shindig/php/gadgets] $ ~/public_html/gadgets

設定を編集、の前に mod_rewrite を有効に。

[maihara@debian:~/public_html/gadgets] $ /etc/apache2/mods-enabled
[maihara@debian:/etc/apache2/mods-enabled] $ sudo ln -s ../mods-available/rewrite.load

んな感じっすか。

で、http://localhost:8080/~maihara/gadgets/files/samplecontainer/samplecontainer.html にアクセスすると以下のような画面が。

curl_init() が失敗しているので php5-curl をインストール。

[maihara@debian:~/public_html/gadgets] $ sudo aptitude install php5-curl
[maihara@debian:~/public_html/gadgets] $ sudo /etc/init.d/apache2 restart

で、そのエラーは出なくなったけど今後は Failed to retrieve gadget content ってエラーが出ております。

見るページを変えます。README にあるように http://localhost:8080/~maihara/gadgets/ifr?url=http://www.labpixies.com/campaigns/todo/todo.xml にアクセス。と、これはこれで Unsupported feature(s): locked-domain つってエラーだ YO!

面倒なってきましたが、ソース src/GadgetServer.php の 163 行目あたりを見てみると http://www.labpixies.com/campaigns/todo/todo.xml にある locked-domain がサポートされていない機能だっつって怒られているようなので、もうちょっと調べないとだけど時間切れ。

というか仕組みをもっと調べないと。

[2008/04/28 追記]

locked-domain はこれ。ユーザのセンシティブなデータを保存するときはこの機能を使えとのことだけど、実際の動作がどう変わるのかはまだわからない。
