根据请求正文在 nodemailer 中发送多个附件

Question

到目前为止，这是我正在解决的代码

function sendMail(req,res){  

  var transporter = nodemailer.createTransport({

    host:process.env.NODEMAILER_HOST,

    port:process.env.NODEMAILER_PORT,

    auth: {

      user: process.env.NODEMAILER_ADDRESS,

      pass: process.env.NODEMAILER_PASS

    }

  })

     mailOptions = {

      from: req.body.from,

      to: req.body.to,

      cc: req.body.cc,

      bcc: req.body.bcc,

      subject: req.body.subject,

      text: req.body.text,

      html: req.body.html,

      attachments: [

        {

          filename: req.body.attachments[0].filename,

          path: req.body.attachments[0].path,

          contentType: req.body.attachments[0].contentType

        },{

          filename: req.body.attachments[1].filename,

          path: req.body.attachments[1].path,

          contentType: req.body.attachments[1].contentType

        }

      ]

    }

  transporter.sendMail(mailOptions,function(error,info){

      if(error){

        console.log(error);

        return res.status(400).json("Failed to Send");

      }else{

        res.status(201).json(req.body);

      }

    });

}

这是我的请求正文

{

"from": "[e-mail]",

"to": "[e-mail]",

"cc": "[e-mail]",

"bcc": "[e-mail]",

"subject": "Test Request 1",

"text": "Example Text 1",

"html": "<p>Some Paragraph</p>",

"attachments": [

    {

        "filename": "test.doc",

        "path": "dirname/test.doc",

        "contentType": "application/doc"

    },{

        "filename": "test-coverted.pdf",

        "path":  "dirname/test-converted.pdf",

        "contentType": "application/pdf"        

    }

]

}

如何遍历附件而不在邮件选项中一一定义？

因为如果我迭代 mailOptions 那么我需要创建单独的传输，这反过来将为不同的附件发送不同的电子邮件。

您在响应正文中获得了相同的 json 对象键，因此您可以直接将附件数组分配给 nodemailer mailOption 对象的附件键。请参阅下文。function sendMail(req,res){&nbsp;&nbsp;&nbsp; var transporter = nodemailer.createTransport({&nbsp; &nbsp; host:process.env.NODEMAILER_HOST,&nbsp; &nbsp; port:process.env.NODEMAILER_PORT,&nbsp; &nbsp; auth: {&nbsp; &nbsp; &nbsp; user: process.env.NODEMAILER_ADDRESS,&nbsp; &nbsp; &nbsp; pass: process.env.NODEMAILER_PASS&nbsp; &nbsp; }&nbsp; })&nbsp;mailOptions = {&nbsp; from: req.body.from,&nbsp; to: req.body.to,&nbsp; cc: req.body.cc,&nbsp; bcc: req.body.bcc,&nbsp; subject: req.body.subject,&nbsp; text: req.body.text,&nbsp; html: req.body.html,&nbsp; attachments: req.body.attachments}
