在GAE标准环境中,我很难使用watch()
在Pub / Sub推送通知中针对Gmail API注册google-api-python-client
来电。
以下是我的代码的相关摘录:
import googleapiclient.discovery
from oauth2client import service_account
SCOPES = ['https://www.googleapis.com/auth/gmail.modify']
SERVICE_ACCOUNT_FILE = '<My-project>-<short-ID>.json'
credentials = service_account.ServiceAccountCredentials.from_json_keyfile_name(SERVICE_ACCOUNT_FILE, scopes=SCOPES)
gmail = googleapiclient.discovery.build('gmail', 'v1', credentials=credentials)
watchRequest = {
'labelIds' : ['INBOX'],
'topicName' : 'projects/<my-project>/topics/<my-topic>'
}
gmail.users().watch(userId='<email-I-need-to-watch>', body=watchRequest).execute()
在解雇了这部分代码之后我得到了:

HttpError: <HttpError 400 when requesting https://www.googleapis.com/gmail/v1/users/<email-I-need-to-watch>/watch?alt=json returned "Bad Request">
关于身份验证和授权,这是我到目前为止所做的:
watch()
请求的主题oauth2client.service_account.Credentials
对象(我看到在日志中成功交换的访问和刷新令牌)。 json服务文件与我的main.py
脚本(我的项目的根目录)放在同一个文件夹中。https://www.googleapis.com/auth/gmail.modify
。我正在使用gmail.modify
访问级别,因为我打算阅读,编写和发送电子邮件和草稿。我的代码或身份验证和授权步骤中是否遗漏了某些内容?
答案 0 :(得分:0)
问题解决了。我错过了从我的域中冒充用户以便阅读他/她的邮箱的代码部分(如here所述)。
更正后的代码如下所示:
import googleapiclient.discovery
from google.oauth2 import service_account
SCOPES = ['https://www.googleapis.com/auth/gmail.modify']
credentials = service_account.Credentials.from_service_account_file(
SERVICE_ACCOUNT_FILE, scopes=SCOPES
)
credentials = credentials.with_subject('<email-I-need-to-watch>')
gmail = googleapiclient.discovery.build('gmail', 'v1', credentials=credentials)
watchRequest = {
'labelIds' : ['INBOX'],
'topicName' : 'projects/<my-project>/topics/<my-topic>'
}
gmail.users().watch(userId='me', body=watchRequest).execute()
