使用CSS作为nodemailer中的电子邮件内容的外部HTML文件

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？

我能够inputHTML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。

不幸的是我找不到任何涵盖这个问题的实际节点制作者版本的例子。

想法？

Answer 1

使用http://styliner.slaks.net

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。

它也可以预先/更新您的电子邮件中的链接，使他们不再是相对的链接。 （也就是说，您可以将“ coverage / local.html ”链接更改为“ \ myhostname \ afolder \ coverage \ local.html ”

这里有一个粗略的，准备好的脚本，我通过电子邮件发送伊斯坦布尔代码覆盖的输出。

/* * 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. * */ var nodemailer = require('nodemailer'); var os = require("os"); var hostname = os.hostname(); var originalFile = process.argv[2].toString(); var baseDir = process.argv[3].toString(); var recipient = process.argv[4].toString(); var Styliner = require('styliner'); var uncDrive = '\\\\' + hostname + '\\DevTC'; var uncPath = baseDir.replace(/.*DevTC/gi, uncDrive); // prependUNCPath is a function called by Styliner for every // link that is found in the HTML. function prependUNCPath(path, type) { return uncPath + path; } // See http://styliner.slaks.net/#about for Styliner options var options = { url : prependUNCPath, noCSS : true }; var styliner = new Styliner(baseDir, options); function sendEmail(source) { var nodemailer = require('nodemailer'); var smtpTransport = require('nodemailer-smtp-transport'); // create reusable transporter object using SMTP transport var transport = nodemailer.createTransport(smtpTransport({ host: 'your-smtp-server.local', // FIXME: Change this! port: 25, })); // setup e-mail data with unicode symbols var mailOptions = { from: 'TeamCity <[e-mail]>', // sender address to: recipient, // list of receivers subject: 'Code Coverage results', // Subject line // text: 'Hello world ?', // plaintext body, not used html: source // html body }; // send mail with defined transport object transport.sendMail(mailOptions, function (error, info) { if (error) { console.log(error); } else { console.log('Message sent: ' + info.response); } }); } var fs = require('fs') // Do the reading of the original index.html, and kick everything off. fs.readFile(originalFile, 'utf8', function (err, data) { if (err) { return console.log(err); } styliner.processHTML(data) .then(function (source) { sendEmail(source); fs.writeFile("newindex.html", source, function (err) { if (err) { return console.log(err); } console.log("The file was saved!"); }); } ); });

我build议使用fs模块的readFile函数来读取你的HTML文件，然后用callback里的电子邮件发送它。

您应该使用内联css，而不是一个单独的文件，因为head元素的HTML呈现等是由provider而不是由nodemailer定义的。

我会推荐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'
