如何将get方法中的JSON数据构造为html ans并将其发送到电子邮件正文

问题描述 投票:0回答:1

需要将从GET METHOD获取的JSON数据作为电子邮件发送。我需要通过获取的JSON对象定义电子邮件的正文。我不知道该如何解决。

这是我的示例代码:

app.get('/userinfo',(req,res)=>{  
    dbconn.query('exec sp_GetDueList',(err,rows,fields)=>{
        if(!err){
            // console.log(rows.recordsets[0][5].Instrument)

           for(let i =0; i<= rows.recordsets[0].length-1; i++){
               console.log(JSON.stringify(rows.recordsets[0][i].Instrument)+ "    "+
               JSON.stringify(rows.recordsets[0][i].ID_No)+ "      "+JSON.stringify(rows.recordsets[0][i].NextDueDate))
           }


        email.main(subject, body, res).catch((err) => {
        console.log(err);
    })

        } else{
            res.send(err);
        }
        res.end();
    })
})

我得到了这样的输出

Hello here's the json
"Coating Thickness Gauge" "BG-05" "2019-10-17T00:00:00.000Z""Coating Thickness Gauge" "BG-06" "2019-10-17T00:00:00.000Z""Coating Thickness Gauge" "BG-07" "2019-10-17T00:00:00.000Z""Coating Thickness Gauge" "BG-09" "2019-09-15T00:00:00.000Z""Coating Thickness Gauge" "BG-10" "2019-09-15T00:00:00.000Z""Coating Thickness Standards" "TS-04" "2019-09-01T00:00:00.000Z""Deep Freezer" "LE-05" "2019-11-07T00:00:00.000Z""DSC Tester " "LE-04" "2019-09-17T00:00:00.000Z""Freezer " "LE-11" "2019-11-07T00:00:00.000Z""Holiday Detector " "HD-349" "2019-11-20T00:00:00.000Z""Holiday Detector " "HD-488" "2019-10-15T00:00:00.000Z""Jeep Meter " "JM-02" "2019-09-26T00:00:00.000Z""Lab Oven " "LE-09" "2019-11-07T00:00:00.000Z""Lab Oven (CDT) " "LE-06" "2019-11-07T00:00:00.000Z""Microscope" "LE-01" "2019-11-07T00:00:00.000Z""Pit Gauge" "PG-10" "2019-09-25T00:00:00.000Z""Pit Gauge" "PG-11" "2019-09-27T00:00:00.000Z""Pit Gauge" "PG-12" "2019-08-18T00:00:00.000Z""Salt Contamination Meter" "TM-01" "2019-08-24T00:00:00.000Z""UT Gage " "UT-02" "2019-06-25T00:00:00.000Z"


现在我想将此数据作为电子邮件正文发送。我知道这个堆栈溢出的人认为这个问题很愚蠢或太容易了。我到处搜索并且找不到有效的模型。

我假设您尚未安装像nodemailer这样的软件包,请通过npm进行安装:npm -i -S nodemailer

var nodemailer = require('nodemailer');
//Here you have to set up your email client, try gmail it's free but otherwise you have to use a service like sendgrid...
var transporter = nodemailer.createTransport({
 service: 'gmail',
 auth: {
  user: 'youremail@gmail.com',
  pass: 'yourpassword'
 }
});

然后您必须在功能内使用电子邮件:

app.get('/userinfo', (req, res) => {
 dbconn.query('exec sp_GetDueList', (err, rows, fields) => {
  if (!err) {
   // console.log(rows.recordsets[0][5].Instrument)
  let emailBody;
   for (let i = 0; i <= rows.recordsets[0].length - 1; i++) {
    console.log(JSON.stringify(rows.recordsets[0][i].Instrument) + "    " +
     emailBody += JSON.stringify(rows.recordsets[0][i].ID_No) + "      " + JSON.stringify(rows.recordsets[0][i].NextDueDate))
   }


   var mailOptions = {
    from: 'youremail@gmail.com',
    to: 'myfriend@yahoo.com',
    subject: 'Sending Email using Node.js',
    html: `<h1>Hello here\'s the json</h1><p>${emailBody}</p>`
   };

   transporter.sendMail(mailOptions, function(error, info) {
    if (error) {
     console.log(error);
    } else {
     console.log('Email sent: ' + info.response);
    }
   });

  } else {
   res.send(err);
  }
  res.end();
 })
})

我尚未测试,也无法真正理解您要尝试执行的操作,但这应该是一个起点,应该将代码拆分为自己的帮助器函数,并使其更可重用。但是,请以此为起点。
