Question

我正在尝试将Python脚本中的Gmail发送给自己，并使用以下代码：

#!/usr/bin/env python

import base64
from email.mime.audio import MIMEAudio
from email.mime.base import MIMEBase
from email.mime.image import MIMEImage
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
import mimetypes
import os
import httplib2

from apiclient import discovery
import oauth2client
from oauth2client import client
from oauth2client import tools
from apiclient import errors

from config import MY_EMAIL, CLIENT_SECRET_FILE

SCOPES = 'https://www.googleapis.com/auth/gmail.compose'
APPLICATION_NAME = 'Gmail API Python Quickstart'

try:
    import argparse
    flags = argparse.ArgumentParser(parents=[tools.argparser]).parse_args()
except ImportError:
    flags = None

def send_message(service, user_id, message):
  """Send an email message.

  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: Message to be sent.

  Returns:
    Sent Message.
  """
  try:
    message = (service.users().messages().send(userId=user_id, body=message)
               .execute())
    print('Message Id: %s' % message['id'])
    return message
  except errors.HttpError as error:
    print('An error occurred: %s' % error)


def create_message(sender, to, subject, message_text):
  """Create a message for an email.

  Args:
    sender: Email address of the sender.
    to: Email address of the receiver.
    subject: The subject of the email message.
    message_text: The text of the email message.

  Returns:
    An object containing a base64url encoded email object.
  """
  message = MIMEText(message_text)
  message['to'] = to
  message['from'] = sender
  message['subject'] = subject
  return {'raw': base64.urlsafe_b64encode(message.as_string())}


def get_credentials():
    """Gets valid user credentials from storage.

    If nothing has been stored, or if the stored credentials are invalid,
    the OAuth2 flow is completed to obtain the new credentials.

        Credentials, the obtained credential.
    """
    home_dir = os.path.expanduser('~')
    credential_dir = os.path.join(home_dir, '.credentials')
    if not os.path.exists(credential_dir):
        os.makedirs(credential_dir)
    credential_path = os.path.join(credential_dir,
                                   'sendEmail.json')

    store = oauth2client.file.Storage(credential_path)
    credentials = store.get()
    if not credentials or credentials.invalid:
        flow = client.flow_from_clientsecrets(CLIENT_SECRET_FILE, SCOPES)
        flow.user_agent = APPLICATION_NAME
        if flags:
            credentials = tools.run_flow(flow, store, flags)
        else: # Needed only for compatibility with Python 2.6
            credentials = tools.run(flow, store)
        print('Storing credentials to ' + credential_path)
    return credentials


def send_email(sender=MY_EMAIL, receiver=MY_EMAIL, subject=None, body=None):
    print("sending email to: %s, from: %s" % (receiver, sender))
    if not body:
        raise Exception("You need a body to send an email")
    credentials = get_credentials()
    http = credentials.authorize(httplib2.Http())
    service = discovery.build('gmail', 'v1', http=http)
    send_message(service, "me", create_message(sender, receiver, subject, body))


if __name__ == "__main__":
    send_email(subject="Test gmail automatic emails", body="Hello world")

我的client_secret.json看起来像

{"web":{"client_id":"23423423423-234234234.apps.googleusercontent.com","project_id":"prime-imagery-4444","auth_uri":"https://accounts.google.com/o/oauth2/auth","token_uri":"https://accounts.google.com/o/oauth2/token","auth_provider_x509_cert_url":"https://www.googleapis.com/oauth2/v1/certs","client_secret":"asdfasdfasdf-trWCLxFdb", "redirect_uris": ["http://localhost:8000/fakeurl"]}}

我在redirect_uris添加了，因为这是我在网上找到的唯一好建议，但我不想重定向。上次我运行此脚本时，让client_secret足以使用Python从我的Gmail帐户发送Gmails。

Answer 1

只需转到Google Dev Console中的凭据，然后添加它所要求的内容即可。 http://localhost:8080/oauth2callback或https://www.samplesite.com/oauth2callback。添加＆＃39; oauth2callback＆＃39;是重定向URI。查看Create authorization credentials。

Answer 2

我遇到了同样的问题。

因此，在添加redirect_uri之后，请不要忘记重新下载clien_secret.json文件。

Answer 3

您需要执行3个步骤。
（其他答案中未指定第2步）：

1）您向Authorized redirect URIs添加了一个uri。
2）Authorized redirect URIs uri等于您在Authorized JavaScript origins中输入的uri，只是斜杠/。

3）再次下载client_secret.json 并将其添加到您的工作目录中。

oauth2client.clientsecrets.InvalidClientSecretsError：客户端类型“web”中缺少属性“redirect_uris”
