如何在Google Drive和App Engine SDK中使用Oauth2服务帐户 [英] How to use Oauth2 service accounts with Google Drive and the App Engine SDK

问题描述

使用App Engine和服务帐户访问Google云端硬盘可以正常工作。为了使它工作，我还必须与服务帐户名称[e-mail]分享我的云端硬盘文件。

但是当我使用GAE SDK I收到401.我认为原因是我的股票的SDK的service_account名称。 SDK的服务帐户名是：test @ localhost根据：

  app_identity.get_service_account_name（）＃返回test @ localhost 
  

SDK控制台中的错误消息：

发生错误：https：//www.googleapis.com/drive/v2/files/0B9-mEÝ....nM/children?alt= json& key = AI ........................ N0返回Invalid Credentials>

这是访问Google云端硬盘的代码：

  def get（self）：
 
 SCOPE = 'https://www.googleapis.com/auth/drive'
 credentials = AppAssertionCredentials（scope = SCOPE）
 logging.info（app_identity.get_service_account_name（））
 http = credentials.authorize （httplib2.Http（））
如果os.environ ['SERVER_SOFTWARE']。startswith（'Development'）：
 service = build（'drive'，'v2'，http = http，developerKey = '... API key ...'）
 else：
 service = buil d（'drive'，'v2'，http = http，developerKey ='... APY key ...'）
＃驱动请求
  

更新：

我的个人观点：这只能用于GAE， SDK，因为我无法使用SDK service_account名称创建Drive共享。或者可以指定另一个服务帐户名称。

解决方案

请检查应用程序拥有的服务帐户，还有一个。

文档包含Python示例代码。

Accessing Google Drive with App Engine and service accounts works fine. To make it work, I also had to share my Drive files with the Service Account Name: [e-mail].

But when I use the GAE SDK I receive a 401. I think the reason is the service_account name of the SDK for my shares. The service account name of the SDK is: test@localhost according to :

app_identity.get_service_account_name()  # returns test@localhost

The error message in the SDK console :

An error occurred: https://www.googleapis.com/drive/v2/files/0B9-mE....................nM/children?alt=json&key=AI........................N0 returned "Invalid Credentials">

This is the code to access Google Drive :

def get(self):

    SCOPE = 'https://www.googleapis.com/auth/drive'
    credentials = AppAssertionCredentials(scope=SCOPE)
    logging.info(app_identity.get_service_account_name())
    http = credentials.authorize(httplib2.Http())
    if os.environ['SERVER_SOFTWARE'].startswith('Development') : 
        service = build('drive', 'v2', http=http, developerKey='...API key...')
    else :
        service = build('drive', 'v2', http=http, developerKey='...APY key...')
    # drive requests        

UPDATE :

My personal opinion : This can only work with GAE and not with the SDK, because I cannot make a Drive share with the SDK service_account name. Or is it possible to specify another service account name.

解决方案

Please check the documentation for Application-owned service accounts, and there is also a video you can watch too.

The docs contain Python sample code.
