我从哪里获得授权的Gmail API服务实例？ （python，gmail api）

Question

我尝试使用我的gmail api代码拨打电话，以便创建草稿，但我无法确定从哪里获得授权的Gmail API服务实例。＆＃34;这是我的代码：

def CreateDraft(service, user_id, message_body):
  CreateDraft('SERVICE THING NEEDS TO BE HERE','me','thisisbody')
  """Create and insert a draft email. Print the returned draft's message and id.

  Args:
    service: Authorized Gmail API service instance.
    user_id: User's email address. The special value "me"
    can be used to indicate the authenticated user.
    message_body: The body of the email message, including headers.

  Returns:
    Draft object, including draft id and message meta data.
  """
  try:
    message = {'message': message_body}
    draft = service.users().drafts().create(userId=user_id, body=message).execute()

    print 'Draft id: %s\nDraft message: %s' % (draft['id'], draft['message'])

    return draft
  except errors.HttpError, error:
    print 'An error occurred: %s' % error
    return None

有谁知道找到授权Gmail API服务实例的位置？我有一个客户ID和秘密，但它与此无关？

我在过去的几天里一直试图解决这个问题并且偶然发现了这个问题，因为它特别是我遇到麻烦的服务部分 - 我正在努力的例子并没有包含这部分。

我无法在剪切和粘贴时获得ragnampiza的代码，但确实设法从各种来源获得解决方案，包括此。

我最终发布了一个解决方案，其中包括身份验证，创建基本消息，获取凭据，获取服务以及最终发送消息。如果有任何帮助，请点击此处：https://github.com/chris-brown-nz/python-gmail-api

所以我明白了。我做了以下事情：

1）将SCOPES改为：

SCOPES = 'https://mail.google.com/' 

2）在您的计算机上（Windows 7）转到“C：\ Users \ YOURUSERNAME \ .credentials

3）删除文件“gmail-quickstart”

4）再次运行代码（quickstart.py）

5）当您的浏览器中弹出消息时，单击“接受”。

6）检查邮件，如果您希望通过api发送电子邮件，那么您应该在那里留言。

凭据文件似乎拥有权限。更改您的权限，然后删除该文件似乎使一切工作完美。因此，如果您希望通过api发送邮件，那么整体代码看起来应该是这样的：
