Chrome扩展开发频道下载权限

Question

在尝试呼叫时使用Chrome Version 27.0.1448.0 dev

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

我收到错误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.

我的权限如下所示。

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

Answer 1

我相信这是一个试验性的特性，所以你可能也需要申请“试验性”许可。
