Chrome擴展開發渠道，下載權限

Question

隨着Chrome Version 27.0.1448.0 dev在嘗試呼叫

chrome.downloads.download(url:song.url); 

我收到錯誤chrome.downloads is not available: You do not have permission to access this API. Ensure that the required permission or manifest property is included in your manifest.json.

我的權限樣子。

"permissions": [ 
    "downloads", 
    "https://*/*", "http://*/*", 
    "tabs" 
], 

Answer 1

我相信這是一個實驗性功能，因此您可能還需要請求「實驗」權限。
