我们有一个在线表格，使人们可以选择上传多个文件。该表格是由第三方创建的，因此我没有任何参与。当某人使用表单上传文件时，它将文件转储到s3存储桶中的新文件夹中。我希望能够执行以下操作：
获取由表单填充程序的上传触发的文件 将文件附加到电子邮件 将电子邮件发送给特定的人。
我已经做了大量的研究，但是我仍然对编码还不陌生，并且正在尝试使用Python，我决定将其作为我的第一门适当语言。
到目前为止，我得到的代码是从我看到并调整的其他示例中借用的。但是到目前为止，仅当我将单个文件上传到存储桶的根目录时，它才向我发送包含文件的电子邮件。不会将多个文件放入存储桶中的文件夹中。这似乎是因为文件夹中文件路径中的/破坏了sendrawemail功能。
此lambda设置为由s3存储桶上的新文件创建时的PUT通知触发。
更新：我现在使用了不同的代码并找到了解决方案。请为此查看底部。

msg.attach(part)

ses_aws_client.send_raw_email(RawMessage={"Data" : msg.as_bytes()})
我希望的是，当一个文件夹或多个文件上传时，我会收到一封包含所有文件作为附件的电子邮件（我知道消息的限制为10mb）。但是，当有多个文件时，似乎正在发送多封电子邮件，每封电子邮件一个文件。而且，如果文件在文件夹中，因此具有一个带有斜杠的键值，则send_raw_email将显示以下错误：
[ERROR] ClientError: An error occurred (InvalidParameterValue) when calling the SendRawEmail operation: Expected ';', got "/"
我认为我需要以某种方式对路径进行编码？有什么方法可以整理所有新上传到一封电子邮件中的文件？
非常欢迎任何帮助。
编辑1：根据Jeril的回复，我正在共享失败中的完整日志条目。另外，我在原始代码块中错过了一行，所以我也将对其进行更新。

现在唯一的问题是，如果我上传多个文件，则每个文件都会收到一封电子邮件。有没有办法将它们全部整理成一封电子邮件？
