Question

我正在开设一个网站，其中将嵌入很多YouTube视频。我想让它更容易嵌入到页面的文章中。

写这篇文章时：

 [youtube]SOMETHING[/youtube]

页面应自动创建：

  <iframe src="//www.youtube.com/embed/SOMETHING" 
         frameborder="0" allowfullscreen></iframe>

那么 - 我该怎么做？我一直在寻找，但一直找不到合适的解决方案。请将您的示例放在ASP.NET / C＃中。

Answer 1

在ASP.NET中创建短代码很容易作为自定义解决方案。在输出文章之前

String html = "[YOUTUBE]Something[\\YOUTUBE]";

String replacementHtml = "<iframe src=\"//www.youtube.com/embed/$1\" frameborder=\"0\" allowfullscreen></iframe>";

Regex shortcodeRegex = new Regex(@"\[YOUTUBE\]([^\[\\]+)\[\\YOUTUBE\]");

String result = shortcodeRegex.Replace(html, replacementHtml);

记下replacementHtml中的$1。这就是匹配内部的内容。

然后将结果输出到页面。

Answer 2

Wordpress风格的短代码应用程序。它将来自数据库或变量中变量的内容中的值[short code /]替换为用户控件内容。

这是我用来处理youtube短代码的方法

<Extension> Public Function ConvertYouTubeShortCode(text As String) As String
    Dim regex__1 As String = "\[youtube:.*?\]"
    Dim matches As MatchCollection = Regex.Matches(text, regex__1)
    If matches.Count = 0 Then
        Return text
    End If
    Dim width As Int32 = 620
    Dim height As Int32 = 349
    Dim BaseURL As String = "http://www.youtube.com/v/"
    For i As Integer = 0 To matches.Count - 1
        Dim length As Int32 = "[youtube:".Length
        Dim mediaFile As String = matches(i).Value.Substring(length, matches(i).Value.Length - length - 1)
        Dim player As String = "<div class=""video-container""><iframe width=""{2}"" height=""{3}"" src=""{4}{1}"" frameborder=""0"" allowfullscreen></iframe></div>"
        Return text.Replace(matches(i).Value, [String].Format(player, i, mediaFile, width, height, BaseURL))
    Next
End Function
