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，以使用保存到驱动器"按钮来提供HTML页面.HTML页面位于 my_address:1337 ，而要保存的文件位于 my_address:1338 .单击保存到驱动器"按钮后，它会长时间显示正在开始下载"，然后显示失败的下载.XHR错误.
我认为这是由于文件是从其他端口提供的，因此我决定对appengine应用程序执行相同的操作.在 http://sayodrive.appspot.com/index.html 上投放的页面，在<一个href ="http://sayodrive.appspot.com/drivefile.jsp" rel ="nofollow"> http://sayodrive.appspot.com/drivefile.jsp ，我遇到了同样的问题.
然后，我决定做一个本地Java Web应用程序:同样的问题.然后，我尝试将内容的配置更改为 attachment (强制下载)，但也无济于事.
我很沮丧，我开始使用Google搜索，并遇到了此页面，该页面声称保存到驱动器"按钮没有实际工作.因此，我回到了 Google云端硬盘SDK的官方页面，发现他们的示例按钮不起作用也.这是一个噩梦吗?

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
