按照说明（here）设置GMail推送通知;和（here）用于在Pub / Sub主题上设置GMail Watch。

（已创建发布/订阅主题和订阅;已在Google Apps中授予对该应用的API客户端访问权限）

问题：

执行以下代码会导致以下（JSON）错误：

{
    "error": {
        "errors": [{
            "domain": "global",
            "reason": "failedPrecondition",
            "message": "Bad Request"
        }],
        "code": 400,
        "message": "Bad Request"
    }
}

尝试的决议：

在创建凭据服务时尝试将GMail帐户作为sub参数。
重新制作的Pub / Sub主题＆amp;订阅。
将域添加到Google Developers Console Project。

代码：

import logging
import httplib2
import json

from apiclient import errors
from apiclient.discovery import build
from oauth2client.client import SignedJwtAssertionCredentials

# Read in service credentials form file
with open('secrets.json') as data_file:
    data = json.load(data_file)

client_email = data["client_email"]
private_key = data["private_key"]

credentials = SignedJwtAssertionCredentials(client_email,
                                            private_key,
                                            'https://mail.google.com/')


def build_gmail_service(credentials):
    # Build a authorized, Gmail service object.
    http = httplib2.Http()
    http = credentials.authorize(http)
    return build('gmail', 'v1', http=http)


def watch_gmail(service, user_id='me'):
    request = {
        'topicName': 'projects/app/topics/gmail',
        'labelIds': ['INBOX'],
        'labelFilterAction': "include"
    }

    try:
        # Make the request.
        response = service.users().watch(userId=user_id,
                                         body=request).execute()

        # Print the results of the request
        if 'error' in response:
            # The API executed, but the script returned an error.
            error = response['error']['details'][0]
            print "Script error! Message: {0}".format(error['errorMessage'])
        else:
            # response successful
            return response
    except errors.HttpError as e:
        # The API encountered a problem before the script started executing.
        logging.error('An error occurred: %s', e.content)


service = build_gmail_service(credentials)
watch_gmail(service, 'user@google_apps_domain.com')

如何解决gcloud gmail-api watch 400（错误请求）？
