我使用AWS SES发送带有附件的电子邮件，因为 sendEmail 功能目前无法发送附件，所以我使用SES中的 sendRawEmail 功能。为了发送原始电子邮件，我将电子邮件转换为MIME文本，如下所示。它有两个附件（转换为base64的图像），一个正文和一些标题。

我已经删除了base64编码的一部分，因为它太长了。这个MIME文本在SES中工作正常，但只附加了第一个文件。第二个文件没有附加到电子邮件中。我已经单独测试了第二个文件，它工作正常。MIME文本可能有什么问题？

找到了这个问题的原因。在MIME文本中，最后的边界应该以双破折号结束--。但在我的情况下，我使用双破折号来分隔两个附件，这导致MIME文本多部分边界结束时没有最后的附件。以下是更正的MIME文本添加多个附件。
字符串
