抽空整理一下前篇SkyDrive失敗史之後的產物，廢話不多說進入主題。

1. 一樣先申請APP權限，網址點我，注意看清楚申請規則，他測試模是只提供5組帳號進行使用，如完成測試完請提出發行申請。

2. 我使用的是dkarzon提供的API，下載如下 : 點我下載

3. 參考範例，作者本身的BLOG，有提供詳細的說明。

備註:

1. Share這個取得的連結是簡碼須先GET正確網址然後置換網址(95行)，這樣取到的連結就是正確的。

2. 此方法目前正確無誤，但不知官方之後是否會修正調，請考慮清楚再使用。

3. 縮圖要資料要很久大約3~4秒，比起SkyDrive秒殺的速度而言，我們懷疑他是當下才製作，所以這部分請仔細考慮清楚。
