【问题描述】：
嗨，我正在尝试只接收那些作为电子邮件回复由我的系统发送的电子邮件。更具体地说，我正在发送带有附件的电子邮件。接收者回复带有附件的电子邮件。
我想在我的系统中显示电子邮件的历史记录，以显示针对哪封电子邮件接收到的附件。例如，如果我已向 pearson B.Pearson B 发送电子邮件。Pearson B 将回复该电子邮件。我想要此的历史记录。我能够发送和接收电子邮件。但问题是我在 a 和 b 之间获取了所有电子邮件（我只想要那些作为特定电子邮件的回复发送的电子邮件）。下面我给出了获取的代码电子邮件。
async function mailreply(req, res) {
Employee.email_reply(req.params.email, function (err, employee) {
var imapConfig = {
user: '*****',
password: '****',
host: 'imap-mail.outlook.com',
port: 993,
tls: true,
tlsOptions: {
rejectUnauthorized: false
}
};
var imap = new Imap(imapConfig);
imap.once("ready", checkMail);
imap.once("error", function (err) {
console.log("Connection error: " + err.stack);
});
imap.connect();
function checkMail() {
imap.openBox("INBOX", false, function (err, mailBox) {
if (err) {
console.error(err);
return;
}
imap.search(["UNSEEN", ["FROM", req.params.email]], function (err, results) {
if (!results || !results.length) {
req.flash('error', 'No reply from selected user.')
res.locals.message = req.flash();
res.redirect(nodeSiteUrl+'/dashboard');
imap.end(); return; }
});
});
}
var mailListener = new MailListener({
username: "******",
password: "******",
host: "imap-mail.outlook.com",
port: 993, // imap port
tls: true,
connTimeout: 10000, // Default by node-imap
authTimeout: 5000, // Default by node-imap,
tlsOptions: { rejectUnauthorized: false },
mailbox: "INBOX", // mailbox to monitor
searchFilter: [ 'UNSEEN', ['FROM', req.params.email] ], // the search filter being used after an IDLE notification has been retrieved ,
markSeen: false, // all fetched email willbe marked as seen and not fetched next time
fetchUnreadOnStart: true, // use it only if you want to get all unread email on lib start. Default is `false`,
mailParserOptions: {streamAttachments: true}, // options to be passed to mailParser lib.
attachments: true, // download attachments as they are encountered to the project directory
attachmentOptions: { directory: "attachments/" } // specify a download directory for attachments
});
mailListener.start();
mailListener.on("server:connected", function(){
console.log("imapConnected");
});
mailListener.on("error", function(err){
console.log('hello');
});
mailListener.on("mail", function(mail, seqno, attributes){
console.log(seqno)
let attachments = [];
var attachment = mail.attachments;
if(attachment) {
for(var i = 0, len = attachment.length; i < len; ++i){
attachments.push(attachment[i].fileName);
}
}
passDatatoPage(mail, attachments);
mailListener.stop();
})
mailListener.on("attachment", function(attachment){
let filepath = './public/attachment/receive/';
let output = fs.createWriteStream(filepath + attachment.fileName);
attachment.stream.pipe(output).on("end", function () {
console.log("All the data in the file has been read");
}).on("close", function (err) {
console.log("Stream has been cloesd.");
});
});
function passDatatoPage(mail, attachments) {
var sender = mail.to[0].address;
var senderName = mail.from[0].name;
var reciver = mail.from[0].address;
const date = moment(mail.date).format('LL');
var subject = mail.subject;
var message = mail.text;
//console.log(attachments);
var result = attachments.map(function(val) {
return val;
}).join(',');
var attachmentArr = result.split(',');
console.log(attachmentArr)
res.render('email-reply', { title: 'Email Reply', to: sender, senderName: senderName, from: reciver, date: date, subject: subject, msg: message, attachments: attachmentArr});
}
});
};
exports.mailreply = mailreply;
