从2014年12月11日开始，Imap nodejs模块不支持1.1和1.2

Question

您好

我正在使用nodejs Imap模块来阅读电子邮件，但从昨天开始，即2014年12月11日，我收到错误

  

“某些消息无法被FETCH（失败）”，

我的代码类似于

 imap.once('ready', function () {
            imap.openBox("[Gmail]/All Mail", true, function (err, box) {
                if (err) {
                    d.reject(err);
                }
                var Moment = require("moment");
                var sDate = Moment(startDate).format("MMMM DD, YYYY");
                var mailSearchOptions = [];
                if (params.mailSearchOptions) {
                    mailSearchOptions = params.mailSearchOptions
                } else {
                    mailSearchOptions.push(['SINCE', sDate]);
                    if (uid) {
                        mailSearchOptions.push(["uid", uid + ":*"])
                    }
                }
                try {
                    imap.search(mailSearchOptions, function (err, results) {
                        if (err) {
                            d.reject(err);

                                        bodyType = toPrefer;
                                    }

                                    head.subject = head.subject ? head.subject[0] : "";
                                    var participants = [];
                                    populateParticipants(head, username, participants);
                                    mails.push({head: head, body: bodyValue, date: mailDate, participants: participants, user: {_id: userid, username: username}, uid: lastUid});

                        f.once('error', function (err) {
                            console.log("error>>>>>>>>>>>"+err) ;
                            d.reject(err);
                        });
                        f.once('end', function () {
                            if (!params.maintainLogs) {
                                return  updateLastUid(lastUid, uid, userid, db).then(function () {
                                    imap.end();
                                });
                            } else {
                                imap.end();
                            }

                        });
                    });
                } catch (e) {
                    console.log("error>>>catch>>>>>>>>"+err) ;
                    d.reject(e);
                }
            });
        });

        imap.once('error', function (err) {
            d.reject(err);
        });

        imap.once('end', function () {
            d.resolve(mails);
        });

        imap.connect();
    });

我检查过，如果我从

中删除'1.1'和'1.2'

var f = imap.fetch(results, { bodies: ['HEADER.FIELDS (TO FROM SUBJECT CC)', '1', '1.1', "1.2"], struct: true }); 

然后变为

var f = imap.fetch(results, { bodies: ['HEADER.FIELDS (TO FROM SUBJECT CC)', '1'], struct: true });

不会给我错误，但通过删除它我无法获得相应的电子邮件数据

昨天之前一切正常......

请帮忙......
