google plus api note

1. 準備
先去 google console
開啟 Google+ api service (Courtesy limit: 1,000 queries/day)
再來去 API Access create client ID and simple API Access
勾選 Application type and Redirect URI 填一填
Redirect URI：Google should redirect the browser after the user allows (or denies) the authorization request(簡單講就是授權完要導去的頁面)

2. API 流程

OAuth2->user 登入/同意取得權限->導回 redirect_url 並取得 access_token ->API Call

event hijacking - flash gaia framework

gaia event hijacking 可是相當博大精深的呀~~
首先要知道有哪些 gaia flow events 可用
beforeGoto
afterGoto
beforeTransitionOut
afterTransitionOut
beforePreload
afterPreload
beforeTransitionIn
afterTransitionIn
afterComplete(no hijacking)

假設要在 transitionIn 之前做一些事，
先宣告
private var releaseGaia:Function;
// in constructor
releaseGaia = Gaia.api.beforeTransitionIn(onBeforeTransitionIn,true);

private function onBeforeTransitionIn(event:GaiaEvent):void {
  // do something...
  releaseGaia();
}

另外在 Navigation 裡常用的手法，
// in init
Gaia.api.afterGoto(setPageId, false, false);

private function setPageId(e:GaiaEvent):void {
  trace(e.validBranch);
}

用來做 breadcrumb  還蠻方便的。
