今日のメモ (3)

とりあえず post できるように、って事で以下なコードを GAE 側に追加。

  def post(self):
    user = users.get_current_user()
    if user:
      d = dict([("result", "Login Success")])
    else:
      d = dict([("result", "Login Unsuccessful")])

    self.response.out.write(simplejson.dumps(d, ensure_ascii=False))

get と同じです。若干冗長。
で、上記を deploy してリトライ。

してみたけれど

ステイタス 500 が戻るな。ざっくりですが実装は以下なカンジ。

        List<NameValuePair> nvps = new ArrayList<NameValuePair>();
        nvps.add(new BasicNameValuePair("login", authKey));
        nvps.add(new BasicNameValuePair("continue", "/"));
 
        HttpResponse response = null;

        HttpPost httpost = new HttpPost("https://test-yamanetoshi.appspot.com/_ah/login");
        try {
        	httpost.setEntity(new UrlEncodedFormEntity(nvps, HTTP.UTF_8));
        	response = httpClient.execute(httpost);

post は無理なのかな。別途調査する事にしてここはスルー。元に戻してみたら当たり前に JSON が戻ってきました。ちょっとこのあたり理解が微妙な所があるんで別途確認します。

なんとなく

手続きを分割してみた。

}

• getAuthKey() は認証できたら authKey を戻す
• getAppspotContent() は authKey 渡して response を戻す
  • できたら URL (てか URI) を渡して response 戻す形が理想か
• とりあえず別スレッドで、ってのは別途検討します
  • この戻りは同期がとれてた方が良さげなので
  • 砂時計とかってどうやるんだろ
