えーっとですね、APIでアクセスしたい人は、まず $room-url/apilogin というcgiにPOSTアクセスをかけてください。 ここなら$room-urlは http://practical-scheme.net/chaton/gauche ですね。 POSTで渡すパラメータはひとつ。'who' という名前で、そちらのクライアントプログラムの名前とかバージョンとか簡単に。 このcgiは返事にS式のalistを返します。 ((post-uri . <post-uri>) (comet-uri . <comet-uri>) (cid . <cid>) (pos . <pos>)) 順不同。後で項目が追加されるかも。 post-uriはpostするためのcgiのurl。comet-uriはlong pollするためのurl cidはこのあとcomet-uriにGETするときに渡す値。 posは現在のログの最新位置で、現在の最新位置以降を取りたい場合はこの値をpの値として使ってください。最初のcometアクセスでアクティブログを全部取りたい場合はこの数値を無視してp=0を渡してください。#
