asp.net-mvc - 谷歌日历无法读取 ICalendar。

Question

操作系统:WinXP您用于访问 Google 日历 (FF3.5) 的程序和版本:

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。该文件在导入到 Outlook 2003 时工作正常。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，但对我来说一切看起来都很好。我将在下面发布示例测试日历 .ics:

生成上述代码的来源就是 mvc View ::

<%@ Import Namespace ="iManageProjectPM.Controllers" %>
<%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage<iCalendar>"%>

Answer 1

ical feed 的问题在于，不同的日历对不同的事物有挑剔的态度，而且至少对我来说，规范有点难以遵循。然而，Kanzaki为像我这样的程序员提供了清晰的规范，做得很好。

现在，您的 ical feed 还需要精确到换行符(Apple 的 ical 不会导入末尾带有错误换行符的 feed)，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:http://ical-validator.herokuapp.com/validate/

最严格的验证器实际上对我来说有误报(即，它报告的错误实际上不是根据规范的错误)，但发现了一些前两个错误没有的错误，这就是为什么我建议运行您的提要通过他们三个。
