嗨，我正试图得到只有那些电子邮件收到的电子邮件回复发送我的系统。更具体地说，我正在发送带有附件的电子邮件，并且收件人回复带有附件的电子邮件。
我想在我的系统中显示哪个附件是针对哪个电子邮件收到的电子邮件的历史。例如，如果我给培生B发了一封邮件，培生B会回复这封邮件。我想知道它的历史。我可以发送和接收电子邮件。但问题是，我得到所有的电子邮件之间获取a和b(我只想要那些电子邮件，这是作为特定电子邮件的回复发送)。下面我给出了获取电子邮件的代码。
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;
在这个代码中，我得到报头错误显示在这里代码错误
我可以知道我的代码有什么问题吗?请提供可能的解决方案在这个代码或提供方式我如何实现我的任务。提前谢谢。
你需要做两件事
-
当您发送电子邮件时，在数据库中存储消息id
-
获取该消息id并根据下面的代码更改搜索过滤器
(使用下面的搜索过滤器根据id查找消息)
var mailListener = new MailListener({
username: "HR2@almashriq.edu.sa",
password: "Tab13510",
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: [ ['HEADER','IN-REPLY-TO',messageId] ], // 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
});
