有谁知道如何告诉 Node.js 的模块 nodemailer 使用外部 HTML 文件（带有样式表的链接）作为电子邮件内容？
我可以输入 HTML 标签作为电子邮件内容，但我更喜欢加载完整的 HTML 文件。我正在使用 nodemailer 1.3.0。
不幸的是，对于实际的 nodemailer 版本，我找不到任何涵盖此问题的示例。
想法？

它是一个 node.js 包，允许您内联您的 css，以便您可以使用 nodemailer 发送完整的 HTML 电子邮件。
它还可以在您的电子邮件中添加/更新链接，使它们不再是相对链接。（即，您可以将“ coverage/local.html ”之类的链接更改为“ \myhostname\afolder\coverage\local.html ”
这是一个粗略且现成的脚本，我敲了它以通过电子邮件发送伊斯坦布尔代码覆盖率的输出。
/*
* Use this script to send Istanbul code coverage results via email.
*
* NPM REQUIREMENTS:
* The following packages need to be installed:
* - npm install styliner
* - npm install nodemailer
* - npm install nodemailer-smtp-transport
*
* Usage: node sendNodeJSCoverageEmail.js <origfile> <basedir> <receipient>
*
* <origfile> : This is the original Istanbul index.html from the code coverage report
* <basedir> : TeamCity directory where the index.html resides. Must contain "DevTC" folder (see below)
* <recipient> : Email address to send the results to.
*
* What it does:
* Istanbul creates an html report for code coverage. It is a complete web page, and has an index.html,
* some CSS style sheets, and relative links to other coverage.
*
* This script takes the index.html, reads the referenced .css files, and inlines the css, so that external
* files are no longer needed. (this is because you can't send multiple files for an html email).
* Also, the relative links are prepended with the UNC path to the files: this means that the recipients
* can click on the links in the html email and they will work.
*
* NOTE: it assumes the TeamCity folder where the coverage reports reside is shared, and also contains the
* folder DevTC (it looks for this folder to do the substitution). All build machines have this
* folder structure.
*

您应该使用内联 css，而不是单独的文件，因为 head 元素的 HTML 呈现等是由提供者而不是由 nodemailer 定义的。
我推荐 mailChim 的 css 内联工具，它非常方便，只需设置
html: '<div style="font - family: verdana; max-width:500px; margin-left">' + 'more string and string'

我建议使用fs模块的readFile函数来读取您的 HTML 文件，然后在回调中通过电子邮件发送它。
