保存到驱动器按钮不起作用 [英] Save To Drive Button Doesn't Work
问题描述
我在NodeJS中编写了一个简单的文件服务器，通过Save To Drive按钮提供HTML页面。 HTML页面在 my_address：1337 处提供，要保存的文件在 my_address：1338 处提供。点击Save To Drive按钮后，会显示正在开始下载很长时间，然后显示 Failed Download。 XHR错误。
我认为这是由于文件是从不同的端口提供的，所以我决定做同样的事情与一个appengine应用程序。页面位于 http://sayodrive.appspot.com/index.html ，并在<我有同样的问题。 rel =nofollow p>
然后我决定做一个本地的Java Web应用程序：同样的问题。然后，我尝试将内容处置更改为附件（强制下载），但也无法正常工作。
沮丧的是，我开始使用谷歌搜索，并遇到这个页面，声称保存到驱动器按钮实际上并不工作。
所以我回到官方Google Drive SDK页面，发现他们的示例按钮不起作用。 这是一个糟糕的梦想吗？

原始示例不起作用，因为 Cache-Control 标头没有被服务器公开。

I wrote a simple file server in NodeJS to serve a HTML page with a Save To Drive button. HTML page is served at my_address:1337 and file to be saved is served at my_address:1338. Upon clicking the Save To Drive button, it shows "Starting Download" for a long time then displays Failed Download. XHR Error.
I thought this was due to the fact that the file was being served from a different port so I decided to do the same with an appengine app. Page served at http://sayodrive.appspot.com/index.html and file served at http://sayodrive.appspot.com/drivefile.jsp, I got the same problem.
Then I decided to do a local Java web application: same problem. Then I tried changing the content disposition to attachment (to force a download) but didn't work either.
Frustrated, I started Googling and came across this page that claims the Save To Drive button doesn't actually work. So I went back to the official Google Drive SDK page and discovered that their example button doesn't work too. Is this a bad dream?

The original sample was not working because the Cache-Control header was not being exposed by the server. This is now fixed.
Access-Control-Expose-Headers: Cache-Control, Content-Encoding, Content-Range
