Google日历无法读取ICalendar.

Question

操作系统:用于访问Google日历(FF3.5)的WinXP程序和版本:

我正在开发一个脚本(基于我在网上找到的现有vCal ASP.NET类)来生成.ics文件.导入到Outlook 2003时,此文件可以正常工作.当我尝试导入到Google日历时,出现以下错误:

导入事件失败:无法处理您的iCal/CSV文件.

我对vCal格式或语法不太了解,但对我来说一切都很好.我将在下面发布示例测试日历.ics:

生成上面代码的源代码只是mvc视图::

Answer 1

ical feed的问题在于不同的日历对于不同的东西是挑剔的,而且至少在我看来,规范很难遵循.然而,Kanzaki在为像我这样的程序员制定规范方面做得很好.

现在,你的feed feed还需要精确到换行符(Apple的不会导入最后错误的换行符)并且我发现这3个验证器的组合效果最好:

• 最基本的:http://severinghaus.org/projects/icv/？url =
• 更好:http://icalvalid.cloudapp.net/Default.aspx
• 最严格的:http://ical-validator.herokuapp.com/validate/

最严格的验证器实际上对我有误报(即,它根据规范报告了实际上没有错误的错误),但是前两个没有发现错误,这就是为什么我建议运行你的所有三个错误的原因他们

Answer 2

Ical 格式规定每行的最大长度为 75 个字节 - 分割行在下一行重新开始，并在开头插入单个空白字符。

我不太确定，但我似乎记得谷歌日历期待这个要求。
