Question

我在使用ICS附件到Gmail / Google日历地址时遇到了一些问题。当我必须编辑事件时，我通过邮件发送更新，其中ICS文件与原始事件的UID相同。但是，GCalendar添加了第二个事件。我怎么能克服这个？

这是第一个ICS文件内容：

BEGIN:VCALENDAR
VERSION:2.0
CALSCALE:GREGORIAN
METHOD:REQUEST
BEGIN:VEVENT
DTSTART:20130425T090000

END:VEVENT
END:VCALENDAR

这是更新ICS文件内容：

BEGIN:VCALENDAR

METHOD:REQUEST
BEGIN:VEVENT
DTSTART:20130425T100000
DTEND:20130425T110000

END:VCALENDAR

当我收到更新文件并点击“将此活动添加到日历”时，我会发现两个不同的事件。

这是原始的原始电子邮件：

以下是ORGANIZER电子邮件的其他测试与发件人电子邮件和ATTENDEE电子邮件相同，与Receiver电子邮件相同。

Answer 1

请参阅RFC5546 Update an Event

活动将移至其他时间。 “UID”的组合属性（未更改）和“SEQUENCE”（碰到1）属性表示更新。

根据你所分享的内容，你可能需要在你的文件中添加一个SEQUENCE属性，并为每次更新增加它。

<强>更新鉴于您添加的ote文件，您缺少组织者和与会者字段，下面的文件是更新工作

此外，您需要将发件人的电子邮件地址与组织者的电子邮件地址以及与会者的电子邮件地址相匹配，以下内容已通过Google日历验证。

在其上应用了以下脚本：

# -*- coding:utf-8 -*-
import smtplib
def sendInvite(fro,to,emlasstring):
    mailServer = smtplib.SMTP('smtp.gmail.com', 587)
    mailServer.ehlo()
    mailServer.starttls()
    mailServer.ehlo()
    mailServer.login(login, password)
    mailServer.sendmail(fro, to, emlasstring)
    mailServer.close()

newUID = "UID:newCALEVENT_TS090519840000000016"
#needed to change UID as once an event was sent its UID is locked and a few attempts were needed to make the script work
eml = open("SO14712929_1.eml",'r').read()
emlhead = "To: "+attendee_eml+CRLF
emlhead += "From:"+fro+CRLF
emlhead += "Reply-To: "+fro+CRLF
eml = emlhead+eml
eml = eml.replace("ORGANIZER:mailto:test@test.eu","ORGANIZER:mailto:"+fro_eml)
eml = eml.replace("ATTENDEE:mailto:test@test.eu","ATTENDEE:mailto:"+attendee_eml)
eml = eml.replace("UID:CALEVENT_TS090519840000000013",newUID)
sendInvite(fro,attendees,eml)
print "invite sent"

eml = open("SO14712929_2.eml",'r').read()
emlhead = "To: "+attendee_eml+CRLF
emlhead += "From:"+fro+CRLF
emlhead += "Reply-To: "+fro+CRLF
eml = emlhead+eml
eml = eml.replace("ORGANIZER:mailto:test@test.eu","ORGANIZER:mailto:"+fro_eml)
eml = eml.replace("ATTENDEE:mailto:test@test.eu","ATTENDEE:mailto:"+attendee_eml)
eml = eml.replace("UID:CALEVENT_TS090519840000000013",newUID)
sendInvite(fro,attendees,eml)
print "updated invite sent"

Answer 2

提供的一些答案并非（完全）正确。

简而言之，您的ATTENDEE媒体资源需要更多参数才能确保Google日历将其视为更新：

ATTENDEE;CUTYPE=INDIVIDUAL;ROLE=REQ-PARTICIPANT;PARTSTAT=NEEDS-ACTION;RSVP=
TRUE;CN=Recipient Name;X-NUM-GUESTS=0:mailto:recipient@gmail.com

我有同样的问题并找到答案我：

使用Google日历本身向我发送了邀请+更新了邀请
比较两个.ics文件
在这两个.ics文件中抛出许多不同的自生变体，以找出哪些参数真正必要

这些是我的发现：

将SEQUENCE从0增加到1（如果您想更新更新，还可以进一步增加）
METHOD必须为REQUEST（* 1）
电子邮件sender不一定与ORGANIZER相同（旁注：但是，Google日历中无法更新 ORGANIZER）
ORGANIZER不需要列为ATTENDEE
电子邮件recipient必须是ATTENDEE
另外（如上所述），ATTENDEE需要其他参数，而不仅仅是:mailto
STATUS不需要提供。编辑：这是发送邀请到谷歌日历/ chrome / mac的情况，但邀请似乎没有在其他组合中得到适当的预览似乎
在doc中占用多行的参数应该在下一行缩进一个空格
在Google日历生成的iCalender对象中，您可能会注意到太长的行会在文档中分成几行，但这不是必需的（例如，您可以提供非常长的字符串说明，只需确保它只需要一行或将它切割成每行用一个空格缩进的行。
额外提示：在原始邀请和更新中使用相同的UID（实际上这不是必需的，但确保您的历史测试结果不会受到影响......）
奖金提示2：为了便于测试，每次都要更改电子邮件的摘要和主题

（* 1）唯一我无法弄清楚的问题是如何让METHOD:PUBLISH可以更新 - 我正在尝试创建一个不应该回复的日历发布应用。如果有人能搞清楚，我将非常感激。： - ）

Answer 3

尝试使用METHOD：PUBLISH而不是METHOD：REQUEST

Icalendar ICS更新无法在谷歌日历中使用
