认为这个问题不是针对Java的,如果你需要用Java来做这件事

public static String extractYTId(String ytUrl) {
    String vId = null;
    Pattern pattern = Pattern.compile(
                     "^https?://.*(?:youtu.be/|v/|u/\\w/|embed/|watch?v=)([^#&?]*).*$", 
                     Pattern.CASE_INSENSITIVE);
    Matcher matcher = pattern.matcher(ytUrl);
    if (matcher.matches()){
        vId = matcher.group(1);
    }
    return vId;
}

适用于类似(也适用于https://...

以前的答案对我不起作用..这是正确的方法。它适用于www.youtube.com和youtu.be链接。

private String getYouTubeId (String youTubeUrl) {
    String pattern = "(?<=youtu.be/|watch\\?v=|/videos/|embed\\/)[^#\\&\\?]*";
    Pattern compiledPattern = Pattern.compile(pattern);
    Matcher matcher = compiledPattern.matcher(youTubeUrl);
    if(matcher.find()){
        return matcher.group();
    } else {
        return "error";  
    }
}

答案 2 :(得分:4)

对我而言,对于您发布的示例链接,此正则表达式看起来更精确(将ID捕获到组1):

http://(?:www\.)?youtu(?:\.be/|be\.com/(?:watch\?v=|v/|embed/|user/(?:[\w#]+/)+))([^&#?\n]+)

demo上,查看右下方窗格中的捕获组。但是,对于第二场比赛,并不完全确定这是一个正确的ID,因为它看起来与其他样本不同 - 如果需要可以调整。

在代码中,例如:

Pattern regex = Pattern.compile("http://(?:www\\.)?youtu(?:\\.be/|be\\.com/(?:watch\\?v=|v/|embed/|user/(?:[\\w#]+/)+))([^&#?\n]+)");
    Matcher regexMatcher = regex.matcher(subjectString);
    if (regexMatcher.find()) {
        VideoID = regexMatcher.group(1);
    } 

答案 3 :(得分:2)

尝试了其他的但在我的情况下失败了 - 调整正则表达式以适合我的网址

public static String extractYoutubeVideoId(String ytUrl) {

        String vId = null;

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

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

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

这个适用于以下网址

使用TấnNguyên的正则表达式:

public String getVideoIdFromYoutubeUrl(String url){
    String videoId = null;
    String regex = "http(?:s)?:\\/\\/(?:m.)?(?:www\\.)?youtu(?:\\.be\\/|be\\.com\\/(?:watch\\?(?:feature=youtu.be\\&)?v=|v\\/|embed\\/|user\\/(?:[\\w#]+\\/)+))([^&#?\\n]+)";
    Pattern pattern = Pattern.compile(regex, Pattern.CASE_INSENSITIVE);
    Matcher matcher = pattern.matcher(url);
    if(matcher.find()){
        videoId = matcher.group(1);
    }
    return videoId;
}

信贷给TấnNguyên。

private fun extractVideoId(ytUrl: String?): String? {
        var videoId: String? = null
        val regex =
            "^((?:https?:)?//)?((?:www|m)\\.)?((?:youtube\\.com|youtu.be|youtube-nocookie.com))(/(?:[\\w\\-]+\\?v=|feature=|watch\\?|e/|embed/|v/)?)([\\w\\-]+)(\\S+)?\$"
        val pattern: Pattern = Pattern.compile(
            regex ,
            Pattern.CASE_INSENSITIVE
        )
        val matcher: Matcher = pattern.matcher(ytUrl)
        if (matcher.matches()) {
            videoId = matcher.group(5)
        }
        return videoId
}

上述带有正则表达式的函数可以从中提取视频ID

这与您问题中发布的链接非常相​​似。

String url = "https://www.youtube.com/watch?v=wZZ7oFKsKzY";
if(url.indexOf("v=") == -1) //there's no video id
    return "";
String id  = url.split("v=")[1]; //everything before the first 'v=' will be the first element, i.e. [0]
int end_of_id = id_to_end.indexOf("&"); //if there are other parameters in the url, get only the id's value
if(end_index != -1)
     id = url.substring(0, end_of_id);
return id;

这对我来说很简单..

public static String getVideoId(@NonNull String videoUrl) {
    String reg = "(?:youtube(?:-nocookie)?\\.com\\/(?:[^\\/\\n\\s]+\\/\\S+\\/|(?:v|e(?:mbed)?)\\/|\\S*?[?&]v=)|youtu\\.be\\/)([a-zA-Z0-9_-]{11})";
    Pattern pattern = Pattern.compile(reg, Pattern.CASE_INSENSITIVE);
    Matcher matcher = pattern.matcher(videoUrl);

    if (matcher.find())
        return matcher.group(1);
    return null;
}

我知道这个话题很老,但是我得到了更多的案例来获取Youtube ID,这是我的正则表达式

http(?:s)?:\/\/(?:m.)?(?:www\.)?youtu(?:\.be\/|be\.com\/(?:watch\?(?:feature=youtu.be\&)?v=|v\/|embed\/|user\/(?:[\w#]+\/)+))([^&#?\n]+)

只需在以下功能中传递youtube链接,它就会检测所有类型的youtube网址

    public static String getYoutubeID(String youtubeUrl) {

    if (TextUtils.isEmpty(youtubeUrl)) {
        return "";
    }
    String video_id = "";

    String expression = "^.*((youtu.be" + "\\/)" + "|(v\\/)|(\\/u\\/w\\/)|(embed\\/)|(watch\\?))\\??v?=?([^#\\&\\?]*).*"; // var regExp = /^.*((youtu.be\/)|(v\/)|(\/u\/\w\/)|(embed\/)|(watch\?))\??v?=?([^#\&\?]*).*/;
    CharSequence input = youtubeUrl;
    Pattern pattern = Pattern.compile(expression, Pattern.CASE_INSENSITIVE);
    Matcher matcher = pattern.matcher(input);
    if (matcher.matches()) {
        String groupIndex1 = matcher.group(7);
        if (groupIndex1 != null && groupIndex1.length() == 11)
            video_id = groupIndex1;
    }
    if (TextUtils.isEmpty(video_id)) {
        if (youtubeUrl.contains("youtu.be/")  ) {
            String spl = youtubeUrl.split("youtu.be/")[1];
            if (spl.contains("\\?")) {
                video_id = spl.split("\\?")[0];
            }else {
                video_id =spl;
            }

        }
    }

    return video_id;
}

建议结合使用两种方法以涵盖尽可能多的格式。

String ID1 = getYoutubeID1(url); regex 1
String ID2 = getYoutubeID2(url); regex 2
String ID3 = getYoutubeID3(url); regex 3

然后,使用if / switch语句选择一个不为null且有效的值。

我认真尝试了上述所有方法,但有时能奏效,有时会失败 我发现这有帮助的任何方式-在此site

private final static String expression = "(?<=watch\\?v=|/videos/|embed\\/|youtu.be\\/|\\/v\\/|\\/e\\/|watch\\?v%3D|watch\\?feature=player_embedded&v=|%2Fvideos%2F|embed%\u200C\u200B2F|youtu.be%2F|%2Fv%2F)[^#\\&\\?\\n]*";
public static String getVideoId(String videoUrl) {
        if (videoUrl == null || videoUrl.trim().length() <= 0){
            return null;
    }
        Pattern pattern = Pattern.compile(expression);
        Matcher matcher = pattern.matcher(videoUrl);
        try {
            if (matcher.find())
                return matcher.group();
        } catch (ArrayIndexOutOfBoundsException ex) {
        ex.printStackTrace();
        }
        return null;
    }

他说

这将适用于两种直接或共享网址的youtube视频网址。

直接网址:https://www.youtube.com/watch?v=XXXXXXXXXXX

共享的网址:https://youtu.be/XXXXXXXXXXX

答案 12 :(得分:0)

没有正则表达式:

字符串url-“ https://www.youtube.com/watch?v=BYrumLBuzHk”

字符串video_id = url.replace(“ https://www.youtube.com/watch?v=”,“”)

所以现在您在字符串video_id中有一个视频ID。
