带车把的 nodemailer 无法正确显示样式

Question

我正在发送一封带有 nodemailer 和 handlebars 的电子邮件，我收到了正确的电子邮件，但未应用样式。

这是我发送电子邮件的代码：

    const hbsConfig = {
        viewEngine: {
            extName: '.hbs',
            partialsDir: path.join(__dirname, '../../../../src/modules/hq-nd/templates/'),
            layoutsDir: path.join(__dirname, '../../../../src/modules/hq-nd/templates/'),
            defaultLayout: ''
        },
        viewPath: path.join(__dirname, '../../../../src/modules/hq-nd/templates/'),
        extName: '.hbs'
    };

    const transporter = nodemailer.createTransport({
        host: 'smtp.sendgrid.net',
        port: 465,
        secure: true,
        auth: {
            user: 'zzz',
            pass: process.env.SENDGRID_SECRET,
        },
    });
    transporter.use('compile', hbs(hbsConfig));
    const email = {
        from: "Boxtribe <123@gmail.com>",
        to: params.username,
        subject: 'Reset your zzz Password',
        template: 'forgot-password',
        context: {
            ...user,
            token: tokenRes.token,
            url: process.env.HARMONY_URL
        }
    };
    const response = await transporter.sendMail(email as Mail.Options);

这是我的模板：

          content="text/html; charset=utf-8"
          http-equiv="Content-Type"

我已经在 http://tryhandlebarsjs.com/ 中进行了测试，它显示正确：

但是邮件里没有申请css类:

发现了问题，这是因为我使用的是类而不是内联样式。当我将样式更改为 inline

时它已修复
