如何使用服务帐户从谷歌驱动器API下载文件？ [英] How to download file from google drive api with service account?

问题描述

你好，谷歌黑客！

我正在使用Drive Service应用并成功上传文件：

I am using Drive Service app and uploaded file successfully like this:

require 'googleauth'
require 'google/apis/drive_v2'

Drive = Google::Apis::DriveV2

upload_source = "/User/my_user_name/hacking.txt"
drive = Drive::DriveService.new
# Drive::AUTH_DRIVE is equal to https://www.googleapis.com/auth/drive
drive.authorization = Google::Auth.get_application_default([Drive::AUTH_DRIVE])
file = drive.insert_file({title: 'hacking.txt'}, upload_source: upload_source)

file 有很多属性，如下所示：
download_url

file has a lot of properties, like this: download_url

但是当我尝试打开在这个 download_url 在浏览器中它显示我空白屏幕。为什么我不能下载它？

But when I try to open this download_url in browser it shows me blank screen. Why I can't download it?

我想，那可能有权限问题？但范围是正确的，上传是成功的......

I guess, that may be there are permission problems? But the scope is correct, and uploading is successful...

推荐答案

答案很简单 - 我们无法从 file 对象，我们必须发送另一个get请求，就像下面这样下载它：

The answer is simple - we cannot download it from file object, we must send another get request, just download it like this:

drive.get_file(file.id, download_dest: '/tmp/my_file.txt')
