我在Google Calendar的Web UI中看到有一个下载。ical版本日历的选项。我想在我开发的应用程序中做到这一点。我正在互联网和文档中查找,如果有这样的东西,但我找不到任何东西……API提供这个功能吗?如果是,我该如何开始呢?
为了确保我理解你的问题,你希望在你的web应用程序上提供一个"下载为。ical"按钮,动态填充来自你的应用程序的特定日历事件数据?
把一个ical文件(或者更准确地说,一个。ics文件)看作是一个字符串,但是具有不同的Mime类型。以下描述了iCalendar格式的基础知识:
http://en.wikipedia.org/wiki/ICalendar在ASP。. NET,我建议创建一个处理程序(。Ashx而不是.aspx),因为如果您不需要提供完整的网页,它会更有效。在处理程序中,将ProcessRequest方法替换为以下内容(来源请访问http://webdevel.blogspot.com/2006/02/how-to-generate-icalendar-file-aspnetc.html)
private string DateFormat
{
get { return "yyyyMMddTHHmmssZ"; } // 20060215T092000Z
}
public void ProcessRequest(HttpContext context)
{
DateTime startDate = DateTime.Now.AddDays(5);
DateTime endDate = startDate.AddMinutes(35);
string organizer = "foo@bar.com";
string location = "My House";
string summary = "My Event";
string description = "Please come to''nMy House";
context.Response.ContentType="text/calendar";
context.Response.AddHeader("Content-disposition", "attachment; filename=appointment.ics");
context.Response.Write("BEGIN:VCALENDAR");
context.Response.Write("'nVERSION:2.0");
context.Response.Write("'nMETHOD:PUBLISH");
context.Response.Write("'nBEGIN:VEVENT");
context.Response.Write("'nORGANIZER:MAILTO:" + organizer);
context.Response.Write("'nDTSTART:" + startDate.ToUniversalTime().ToString(DateFormat));
context.Response.Write("'nDTEND:" + endDate.ToUniversalTime().ToString(DateFormat));
context.Response.Write("'nLOCATION:" + location);
context.Response.Write("'nUID:" + DateTime.Now.ToUniversalTime().ToString(DateFormat) + "@mysite.com");
context.Response.Write("'nDTSTAMP:" + DateTime.Now.ToUniversalTime().ToString(DateFormat));
context.Response.Write("'nSUMMARY:" + summary);
context.Response.Write("'nDESCRIPTION:" + description);
context.Response.Write("'nPRIORITY:5");
context.Response.Write("'nCLASS:PUBLIC");
context.Response.Write("'nEND:VEVENT");
context.Response.Write("'nEND:VCALENDAR");
context.Response.End();
