使用 gmail API (python) 发送电子邮件时出现 403 错误

问题描述

我正在尝试使用 Python 中的 Gmail API 发送电子邮件.我想我遵循了相关文档和 YouTube 视频.

我遇到了这个错误:

googleapiclient.errors.HttpError: HttpError 403 请求 https://www.googleapis.com/gmail/v1/users/me/messages/send?alt=json 时返回权限不足"

这是我的脚本:

#!/usr/bin/env python从 googleapiclient.discovery 导入构建从 httplib2 导入 Http从 oauth2client 导入文件、客户端、工具从 email.mime.text 导入 MIMEText导入 base64导入错误范围 = 'https://mail.google.com/'CLIENT_SECRET = 'client_secret.json'store = file.Storage('storage.json')credz = store.get()如果不是 credz 或 credz.invalid:标志 = tools.argparser.parse_args(args=[])流 = client.flow_from_clientsecrets(CLIENT_SECRET, SCOPES)credz = tools.run_flow(flow, store, flags)GMAIL = build('gmail', 'v1', http=credz.authorize(Http()))def CreateMessage(sender, to, subject, message_text):"""为电子邮件创建消息.参数:发件人:发件人的电子邮件地址.to:收件人的电子邮件地址.主题:电子邮件的主题.message_text:电子邮件消息的文本.返回:一个包含 base64url 编码的电子邮件对象的对象."""消息 = MIMEText(message_text)消息['至'] = 至消息['来自'] = 发件人消息['主题'] = 主题返回 {'raw': base64.urlsafe_b64encode(message.as_string())}def SendMessage(service, user_id, message):"""发送电子邮件.参数:service:授权的 Gmail API 服务实例.user_id:用户的电子邮件地址.特殊值我"可用于指示经过身份验证的用户.消息:要发送的消息.返回:发送消息."""尝试:消息 = (service.users().messages().send(userId=user_id, body=message).执行())打印 '消息 ID:%s' % 消息 ['id']回信除了errors.HttpError，错误:打印 '发生错误:%s' % 错误message = CreateMessage('[email protected]', '[email protected]', 'test_subject', 'foo')打印信息SendMessage(GMAIL，'我'，消息)

我尝试添加范围、尝试不同的电子邮件等.我也通过登录浏览器进行了身份验证.(顺便说一下，[email protected] 是一个虚拟电子邮件)

解决方案

尝试删除生成的 storage.json 文件，然后重试.

您可能正在尝试使用不同范围的此脚本，因此storage.json"可能包含错误的详细信息.

I'm trying to send an email using the Gmail API in python. I think I followed the relevant documentation and youtube vids.

I'm running into this error:

googleapiclient.errors.HttpError: HttpError 403 when requesting https://www.googleapis.com/gmail/v1/users/me/messages/send?alt=json returned "Insufficient Permission"

Here is my script:

    #!/usr/bin/env python

    from googleapiclient.discovery import build
    from httplib2 import Http
    from oauth2client import file, client, tools
    from email.mime.text import MIMEText
    import base64
    import errors

    SCOPES = 'https://mail.google.com/'
    CLIENT_SECRET = 'client_secret.json'

    store = file.Storage('storage.json')
    credz = store.get()
    if not credz or credz.invalid:
        flags = tools.argparser.parse_args(args=[])
        flow = client.flow_from_clientsecrets(CLIENT_SECRET, SCOPES)
        credz = tools.run_flow(flow, store, flags)

    GMAIL = build('gmail', 'v1', http=credz.authorize(Http()))

    def CreateMessage(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 SendMessage(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, error:
        print 'An error occurred: %s' % error

    message = CreateMessage('[email protected]', '[email protected]', 'test_subject', 'foo')
    print message
    SendMessage(GMAIL, 'me', message)

I tried adding scopes, trying different emails, etc. I have authenticated by logging into my browser as well. (The [email protected] is a dummy email btw)

解决方案

Try deleting generated storage.json file and then try again afresh.

you might be trying this script with different scopes so "storage.json" might be having wrong details.
