有可以在URL上传递的标准日期/时间格式吗？ [英] Is there a standard date/time format that can be passed on a URL?

问题描述

查看 DateTimeFormatInfo 文档，它似乎所有的标准格式都有冒号，这使得它们传递给url不愉快/不可能。

有没有标准的格式来传递一个URL的日期时间，最好是由.NET自动解析的？

更新： / p>

这个数据的消费者将是某种类型的Web服务 - 它将是一个简单的HTTP GET，在查询字符串中具有此值，或者将REST的值在某个地方的URL。

ISO 8601 管理日期/时间格式，根据wiki文章，使用 ToString（yyyyMMddTHHmmssZ）应该是st至少符合标准。不幸的是，它不会被ASP.NET MVC自动拾取（还没有尝试任何其他的东西）。对于什么是值得的，ASP.NET MVC不会自动将ticks转换为datetime，这让我感到惊讶。

解决方案

将所有东西放在一起，成为一个答案：

你可以这样做：

 code> string urlSafeDateString = HttpServerUtility.UrlTokenEncode（date.ToUniversalTime（）。ToString（System.Globalization.CultureInfo.InvariantCulture）.ToCharArray（））; 
 
 DateTime date = DateTime.Parse（new string（HttpServerUtility.UrlTokenDecode（urlSafeDateString）），System.Globalization.CultureInfo.InvariantCulture）.ToLocalTime（）; 
  

或者你可以这样做：

  string urlSafeDateString = date.ToUniversalTime（）。ToString（yyyyMMddTHHmmss，System.Globalization.CultureInfo.InvariantCulture）; 
 
 DateTime date = DateTime.ParseExact（urlSafeDateString，yyyyMMddTHHmmss，System.Globalization.CultureInfo.InvariantCulture）.ToLocalTime（）; 
  

Looking at the DateTimeFormatInfo documentation, it appears that all the standard formats have colons in them, which makes passing them on a url unpleasant/impossible.

Is there a standardized format for passing a datetime on a url, preferably one that can be automatically parsed by .NET?

Update: A little clarification

The consumer of this data is going to be web service of some kind - it'll either be a simple HTTP GET with this value in the querystring, or it'll be REST with the value in the url somewhere.

ISO 8601 governs date/time formatting, and according to the wiki article, using ToString("yyyyMMddTHHmmssZ") should be standards-compliant at least. Unfortunately, it doesn't get picked up automatically by ASP.NET MVC (haven't tried anything else yet). For what it's worth, ASP.NET MVC won't automatically convert ticks to a datetime either, which surprised me.

解决方案

I'll put everything together into one answer:

You could do something like this:

        string urlSafeDateString = HttpServerUtility.UrlTokenEncode(date.ToUniversalTime().ToString(System.Globalization.CultureInfo.InvariantCulture).ToCharArray());

        DateTime date = DateTime.Parse(new string(HttpServerUtility.UrlTokenDecode(urlSafeDateString)), System.Globalization.CultureInfo.InvariantCulture).ToLocalTime();

Or you could do something like this:

        string urlSafeDateString = date.ToUniversalTime().ToString("yyyyMMddTHHmmss", System.Globalization.CultureInfo.InvariantCulture);

        DateTime date = DateTime.ParseExact(urlSafeDateString, "yyyyMMddTHHmmss", System.Globalization.CultureInfo.InvariantCulture).ToLocalTime();
