有三种类型的google api client_id：
1. Web应用程序
2.服务帐户
3.已安装的应用程序
我已成功使用> A=outer(outer(1:10,1:10,"+"),1:10,"+")
> A[1,2,3]
[1] 6
> A[4,8,9]
[1] 21
基于oauth2client，但在3. Installed application上失败了。我想用oauth2.0 2. Service Account访问我自己的gmail收件箱。
Credentials我得到的异常与question相同。尝试将import imaplib
import json
import urllib2
from oauth2client.client import SignedJwtAssertionCredentials
from httplib2 import Http
from apiclient.discovery import build
import os
reldir = os.path.dirname(os.path.relpath(__file__))
CLIENT_SECRET_FILE = os.path.join(reldir, 'gmail_service.json')
OAUTH_SCOPE = "https://mail.google.com"
GMAIL_ADDRESS = 'my_gmail_address@gmail.com'
def jwt_oauth2():
'''
https://developers.google.com/identity/protocols/OAuth2ServiceAccount
'''
with open(CLIENT_SECRET_FILE) as f:
data = json.loads(f.read())
private_key = data['private_key']
client_email = data['client_email']
credentials = SignedJwtAssertionCredentials(
client_email, private_key, scope=OAUTH_SCOPE)
http_auth = credentials.authorize(Http())
try:
gmail_service = build('gmail', 'v1', http=http_auth)
threads = gmail_service.users().messages().list(userId='me').execute()
except Exception as e:
return e
添加到凭据中时遇到另一个例外：
sub=GMAIL_ADDRESS
我试图找出问题，AccessTokenRefreshError: unauthorized_client: Unauthorized client or scope in request.没有credentials：
sub尝试将>>> credentials = SignedJwtAssertionCredentials(
client_email, private_key, scope=OAUTH_SCOPE)
>>> http = credentials.authorize(Http())
>>> credentials.access_token
>>> credentials.refresh(http)
>>> credentials.access_token
u'ya29.pAGJjddCXjwsiHFN6hKU1yAkdWN7xMJbks5O76Pmrpe1hW1BbgwfZifjp81aDE55ALMVgjv-yBYiyQ'
>>> gmail_service = build('gmail', 'v1', http=http)
>>> request = gmail_service.users().messages().list(userId='me')
>>> response = request.execute()
{
"error": {
"errors": [
{
"domain": "global",
"reason": "failedPrecondition",
"message": "Bad Request"
}
],
"code": 400,
"message": "Bad Request"
}
}
与credentials：
sub我发现了一个类似的问题Google OAuth2 Service Account HTTP/REST Authentication，但我对>>> credentials = SignedJwtAssertionCredentials(
client_email, private_key, scope=OAUTH_SCOPE, sub=GMAIL_ADDRESS)
>>> http = credentials.authorize(Http())
>>> credentials.access_token
>>> credentials.refresh(http)
AccessTokenRefreshError: unauthorized_client: Unauthorized client or scope in request.
了解不多。任何帮助将不胜感激。

您应该使用您指定要模拟的帐户的子字段。
说，使用您的服务帐户，您希望获得用户user@domain.com的详细信息，子字段应填充为：
sub: user@domain.com
您还应确保已向域中的用户授予服务帐户访问权限。 请参阅 - https://developers.google.com/drive/web/delegation
