javascript - Nodemailer 和 HTML 模板 - 遍历数组中的项目

问题描述

我已经开始使用 Nodemailer 并且可以发送电子邮件了。我决定使用 HTML 作为一种格式，并且包括 CSS 的引导程序。我所有的模板变量都得到了正确的插值，但我需要遍历一个数组并显示这些项目。我目前无法执行此操作，并且需要一些帮助。

router.post('/', auth.isAuthenticated, async (req, res) => {
    try {

        // Add request to new object - to save
        let request = new Request(req.body);

        // Save request
        let savedRequest = await request.save();

        // Get request ID and save to associated project
        let project = await Project.findByIdAndUpdate(
            request.project,
            {
                $push: { requests: savedRequest._id }
            },
            { new: true }
        );

        // If notifyPM is true, send request to project manager
        if (req.body.notifyPM) {


            let mailOptions = {
                from: process.env.NODEMAILER_EMAIL,
                to: savedRequest.projectManager.email,
                subject: `PROJECT REQUEST FOR -- ${project.projectTitle} -- FROM -- ${savedRequest.userName}`,
                html: `
                <!DOCTYPE html>

                }
            });
        }

        res.status(200).json({
            message: 'Request saved successfully',
            request: savedRequest
        });
    } catch (error) {
        res.status(500).json({
            message: 'Error saving request'
        });
    }
});

解决方案

这是我的 EJS 渲染（省略了 HTML）

// Render EJS
            const data = await ejs.renderFile(
                __dirname + '/workOrderEmailTemplate.ejs',
                {
                    user: wo.user,
                    finalDuration: wo.finalDuration,
                    title: wo.projectTitle,
                    showCode: wo.showCode,
                    episode: wo.episode,
                    woNumber: wo.workOrderNumber,
                    location: wo.location,
                    services: wo.services,
                    clientPresent: wo.clientPresent,
                    woType: wo.workOrderType,
                    notes: wo.notes
                }
            );

            const mailOptions = {
                from: process.env.NODEMAILER_EMAIL,
                to: wo.projectManagerEmail,
                subject: `WORK ORDER for -- ${wo.projectTitle} -- from -- ${wo.user}`,
                html: data
            };

            transporter.sendMail(mailOptions, function(err, info) {
                if (err) {
                    console.log('Error in SendMail function', err);
                } else {
                    console.log('Message sent: ' + info.response);
                }
            });
