我正在尝试使用 Gmail API 发送电子邮件。我已成功通过身份验证,并且我的计算机上有一个 client_secret.json 文件。
我已经能够使用 Gmail API 网站上的快速入门示例获取标签列表
我已成功将范围重置为
SCOPES = 'https://mail.google.com'
允许完全访问我的 Gmail 帐户。
我有一个 python 脚本,编译自here https://developers.google.com/gmail/api/quickstart/python#step_3_set_up_the_sample and here https://developers.google.com/gmail/api/guides/sending#sending_messages。见下文。执行脚本时,我收到以下错误消息:
发生错误:https://www.googleapis.com/gmail/v1/users/me/messages/send?alt=json 返回“'原始'RFC822 有效负载消息字符串或通过 /upload/* 需要 URL 上传消息”>
关于我做错了什么以及如何解决它有什么想法吗?
