从函数中访问数组时出现问题

Question

我正在创建一个应用程序，它会抓取 Indeed，然后会向我发送数组的电子邮件。我已经成功废贴，可以发邮件了；但是当我尝试发送电子邮件时，我收到的只是电子邮件中的 [object, Object]。

const PORT =8000;
const axios = require('axios');
const cheerio = require('cheerio');
const express = require('express');
const nodemailer = require('nodemailer');

const app = express()
const url = 'https://www.indeed.com/jobs?q=Junior+engineer&l=Remote&fromage=1';

//Axios will return a promise and once the promise is returned we will get the response(data)//

axios(url)
    .then(response => {
        const html = response.data
        const $ = cheerio.load(html)
        const indeedJobPostings =[]

        //After cheerio has loaded our html, we begin by searching through a .resultContent class for our needed title and company //
        $('.resultContent',html).each(function(){
             title = $(this).find('.jobTitle').text()
             company = $(this).find('.companyName').text()
            indeedJobPostings.push({
                title, company
            })
            
        })
        ////////////
        let transporter = nodemailer.createTransport({
            host: 'smtp.gmail.com',
            port: 587,
            secure: false,
            requireTLS: true,
            auth: {
                user: 'username',
                pass: 'password'
            }
        });

        let mailOptions = {
            from: 'email',
            to: 'email',
            subject: 'Test',
            html: `<h2>Here are your daily job postings from Indeed:</h2> <ul>${indeedJobPostings}</ul>`
        };

        console.log('post log',indeedJobPostings, mailOptions)

        transporter.sendMail(mailOptions, (error, info) => {
            if (error) {
                return console.log(error.message);
            }
            console.log('success');
        });

        ///////////
    }).catch(err => console.log(err))


app.listen(PORT, () => console.log(`Server running on PORT ${PORT}`))

当我 console.log(indeedJobPosting, mailOptions) indeedJobPostings 打印为可疑但 mailOptions 发送此：

{
  from: 'email',
  to: 'email',
  subject: 'Test',
  html: '<h2>Here are your daily job postings from Indeed:</h2> <ul>[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]</ul>'
}

Answer 1

indeedJobPostings.push({
    title, company
})

用具有 title 和 company 属性的对象填充 indeedJobPostings 数组。将其转换为模板表达式中的字符串

${indeedJobPostings}

创建一个逗号分隔的“[object Object]”字符串列表，这些字符串由 Object.prototype.toString 将对象转换为字符串，然后由 Array.prototype.toString 使用逗号分隔符在其自身 toString操作。

您可以在创建电子邮件正文时将 indeedJobPostings 对象条目显式转换为文本，或者首先推送文本：

indeedJobPostings.push(`Title: ${title}\nCompany: ${company}\n\n`);
