Question

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，并在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

我已成功将我的范围重置为

SCOPES = 'https://mail.google.com'

允许完全访问我的Gmail帐户。

我有一个python脚本，由here和here编译而成。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“'raw”RFC822有效负载消息字符串或通过/ upload / * URL上传消息需要“＆GT;

对我做错了什么以及如何解决它的想法？
