当 OTRS 从 IMAP 帐户提取电子邮件时,它会忘记原始发送日期并将其替换为提取日期 (!)。
通常这不是问题,但当您将包含许多电子邮件的现有 IMAP 文件夹导入时,OTRS
所有日期都会设置为导入数据。
这可不是什么好事,我想知道是否有办法让 OTRS 读取电子邮件标题并使用它来替换表create_time
中的字段article
。我考虑使用邮政局长的过滤器模块(或类似的东西)。
如何让 OTRS 读取date
电子邮件中的标题并使用那日期为create_time
?
答案1
简短的回答是:这是不可能的。详细的回答是:如果您想这样做,您需要修改 TicketCreate() 方法,因为它目前只将当前时间作为新票的创建日期。

我发现的解决方案是向 MySQL 添加一个触发器,如下所示:
在article_attachement
CREATE TRIGGER bi_article_attachement_each BEFORE INSERT ON article_attachment
FOR EACH ROW
BEGIN
DECLARE newdate datetime;
SET newdate = null;
SELECT create_time INTO newdate FROM article_plain ap WHERE ap.article_id = new.article_id LIMIT 1;
IF newdate IS NOT NULL THEN
SET new.create_time = newdate;
SET new.change_time = newdate;
END IF;
END
在article_plain
CREATE TRIGGER bi_article_plain_each BEFORE INSERT ON article_plain
FOR EACH ROW
BEGIN
DECLARE datestr CHAR(40);
DECLARE newdate DATETIME;
DECLARE mindate DATETIME;
DECLARE myticket BIGINT;
SET datestr = mid(new.body,locate('Date: ',new.body)+6,40);
SET newdate = coalesce(str_to_date(datestr,'%a, %e %M %Y %k:%i:%s'),str_to_date(datestr,'%e %M %Y %k:%i:%s'),new.create_time);
SET new.create_time = newdate;
UPDATE article a SET a.create_time = newdate WHERE a.id = new.article_id;
SELECT a.ticket_id INTO myticket FROM article a WHERE a.id = new.article_id LIMIT 1;
SELECT least(min(a.create_time),new.create_time) INTO mindate FROM article a WHERE a.ticket_id = myticket;
UPDATE ticket t
SET t.create_time = least(t.create_time, mindate)
, t.create_time_unix = unix_timestamp(least(t.create_time, mindate))
WHERE t.id = myticket;
END
同一张表,但更新后
CREATE TRIGGER ua_article_plain_each AFTER UPDATE ON article_plain
FOR EACH ROW
BEGIN
IF old.create_time <> new.create_time THEN BEGIN
UPDATE article a SET a.create_time = new.create_time, a.change_time = new.create_time WHERE a.id = new.article_id;
END; END IF;
END
最后触发ticket
:
CREATE TRIGGER bu_ticket_each BEFORE UPDATE ON ticket
FOR EACH ROW
BEGIN
DECLARE newtn varchar(50);
DECLARE newdate varchar(12);
DECLARE filter varchar(13);
SET newdate = date_format(old.create_time,'%Y%m%d%H%i');
SET filter = concat(newdate,'%');
SELECT concat(newdate,ifnull(right(concat('0000',right(max(tn),4)+1),4),'0001')) INTO newtn
FROM ticket
WHERE tn LIKE filter;
SET new.tn = newtn;
END

我遇到了同样的问题。非常感谢您的帮助。这些程序对我来说不起作用,所以我更改了它并使用临时表。
CREATE TABLE `article_plain_date` (
`article_plain_FK` INT(11) NOT NULL,
`atricle_ID` INT(11) DEFAULT NULL,
`ticket_ID` INT(11) DEFAULT NULL,
`create_date` DATETIME DEFAULT NULL,
PRIMARY KEY (`article_plain_FK`)
) ENGINE=MYISAM DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;
INSERT INTO article_plain_date
SELECT p.id,a.id,t.id,IF(STR_TO_DATE(MID(body,LOCATE('Date: ',body)+6,25),'%a, %e %M %Y %k:%i:%s'),STR_TO_DATE(MID(body,LOCATE('Date: ',body)+6,25),'%a, %e %M %Y %k:%i:%s'),p.create_time) AS create_date FROM otrs.article_plain p
JOIN article a ON (p.`article_id` = a.id)
JOIN ticket t ON (a.`ticket_id` = t.id);
UPDATE article_plain p
JOIN article_plain_date d ON (p.`article_id` = d.`atricle_ID`)
SET p.`create_time` = d.`create_date`;
UPDATE article a
JOIN article_plain_date d ON (a.id = d.`atricle_ID`)
SET a.`create_time` = d.`create_date`;
UPDATE ticket t
JOIN article_plain_date d ON (t.id = d.`ticket_ID`)
SET t.`create_time` = d.`create_date`, t.`create_time_unix` = UNIX_TIMESTAMP(d.`create_date`);
