android - Android 中 Facebook SDK 的 requestNewPublishPermissions

Question

目前我打电话requestNewPublishPermissions请求publish_stream许可。

有没有办法让我查看用户是否已经授权了该权限，所以我不需要再次询问？

我认为Session.isPublishPermission("publish_stream")可能是这样，但它似乎与预期的行为不符。

To check if the user has already authorized a permission, you have to call the API:

\GET /me/permissions

You'll get the response in the format:

{
  "data": [
    {
      "installed": 1,
      "basic_info": 1,
      "public_profile": 1,
      "publish_stream": 1,
      "user_notes": 1,
      "user_friends": 1
    }
  ],
}

If this have the "publish_stream": 1 permission that means the user has authorized the app to publish on his behalf.

Code (if using android SDK)-

new Request(
    session,
    "/me/permissions",
    null,
    HttpMethod.GET,
    new Request.Callback() {
        public void onCompleted(Response response) {
            /* handle the result */
        }
    }
).executeAsync();
