lotus-notes - 使用 MIME 控制电子邮件中 ​​HTML 和附件的顺序

Question

我的数据库有一些注释文档，它们是电子邮件模板。它们有一个名称、一个附件字段和一个 html 字段。

我正在尝试编写一个代理程序，该代理程序可以获取此文档并构建包含 html 和附件的内部电子邮件。

我的代码有效，但电子邮件如下所示:

我不希望附件位于顶部。我更喜欢将它嵌入到 html 中。当我抓取 html 文本时，我会替换一些值，例如用户名，因此电子邮件可以是动态的。我只是输入“|REPLACE1|”我想在其中输入用户名。有没有办法用“|FILEREPLACE1|”编写html这样我就可以动态附加文件？

如果没有，我可以将附件放在电子邮件底部吗？

我喜欢电子邮件类(class)!很棒的概念。我希望它对你有用。

我没有答案，但我可能有解决方案吗？如果可以的话，我强烈建议您更改您的电子邮件，以便您有一个集中存储的链接，而不是附件!如果正如您所说，这是内部电子邮件，为什么要创建重复项？

您可以链接到/DatabasePath/xpViewEmailsAll/$First/$File/To%20Terminate%20an%20Employee%20(manager).pdf 但我建议您链接到/Database/AttachmentRequests/To%20Terminate %20an%20Employee%20(manager).pdf 其中“AttachmentRequests”是带有表单公式的 View ，第一个排序列包含提供的每个文件的名称，指定的表单会拦截打开并启动附件本身。这样，它就可以适用于 Notes 或 Web 客户端，并且当在某些可预见的困惑 future 出现需要时，您将能够更改行为以报告“此已移动”，或者可能将它们转发到某些尚不正确的页面-现有的 Intranet 站点。
