从链接获取youtube id [英] getting the youtube id from a link

问题描述

我收到此代码以从
www.youtube.com/watch?v=xxxxxxx

I got this code to get the youtube id from the links like www.youtube.com/watch?v=xxxxxxx

  URL youtubeURL = new URL(link);
  youtubeURL.getQuery();

基本上这会让我很容易识别你的身份v = xxxxxxxx

basically this will get me the id easily v=xxxxxxxx

但我注意到有时youtube链接会像这样

but I noticed sometime youtube links will be like this

http://gdata.youtube.com/feeds/api/videos/xxxxxx

我从Feed
获取链接所以我也是需要为那个构建一个正则表达式或者是一个解析器来为我做这个吗？

I am getting the links from a feed so do I need to build a regex for that or theres a parser to get that for me ?

推荐答案

试过其他的但我的失败了case - 调整正则表达式以适合我的网址

Tried the other ones but failed in my case - adjusted the regex to fit for my urls

String pattern = "(?<=watch\\?v=|/videos/|embed\\/)[^#\\&\\?]*";

    Pattern compiledPattern = Pattern.compile(pattern);
    Matcher matcher = compiledPattern.matcher(url);

    if(matcher.find()){
        return matcher.group();
    }

这适用于:(您还可以实施安全检查youtubeid length = 11）

This one works for: (you could also implement a security check youtubeid length = 11 )
