使用Jsoup检测脚本中的文本并获取脚本标签中的文本 [英] Detect text in script and Obtain text within script tag using Jsoup
问题描述
我想编码以获取价值流，但失败了. 网址检测 http://m.xemtvhd.com/vtv1.php
I want to code get value stream but fail. url detect http://m.xemtvhd.com/vtv1.php
如何获取价值流: 123.30.215.65/hls/4545780bfa790819/5/3/d836ad614748cdab11c9df291254cf836f21144da20bf08142455a8735b328ca/dnR2MQ==_m.m3u8 使用Jsoup吗?
How to get value stream : http://123.30.215.65/hls/4545780bfa790819/5/3/d836ad614748cdab11c9df291254cf836f21144da20bf08142455a8735b328ca/dnR2MQ==_m.m3u8 using Jsoup ?
<html>
<head>
<style>html,body{margin:0;padding:0;background:#000;;}</style>
<meta charset="utf-8">
<script src="https://code.jquery.com/jquery-2.1.4.js"></script>
<script type="text/javascript" src="https://cdn.jsdelivr.net/clappr/latest/clappr.min.js"></script>
<meta name="referrer" content="no-referrer">
</head>
<body>
<div style="width: 100%;">
</div>
<div id="player"></div>
<script>
player = new Clappr.Player({source: "http://123.30.215.65/hls/4545780bfa790819/5/3/d836ad614748cdab11c9df291254cf836f21144da20bf08142455a8735b328ca/dnR2MQ==_m.m3u8",
parentId: '#player',
width: '100%', height: "100%",
hideMediaControl: true,
autoPlay: true
});
</script>
</body>
</html>
用Java代码编写我:
Code Java me :
Elements script = doc.select("script");
Pattern p = Pattern.compile("player = new Clappr.Player(\\(\"source:{\", \"(.*)\", false\\)");
// ^^ is the capturing group
String url = "";
for (Element element : script) {
Matcher m = p.matcher(element.data());
if (m.find()){
url = m.group(1);
}
}
System.out.println(url);
请支持 .谢谢！
please support . thank you !
推荐答案
您的正则表达式中存在一些错误，例如，您实际上将{放在了source之后，因此您需要对其进行两次转义，因为{i,j}是量词，,也不是一个好地方，我不知道你为什么这么做，它与句子的顺序不一样
There is some mistakes in your regex, for ex you put the { after source in fact it's before and you need to double escape it because {i,j} are quantifiers, and the , is also not at good place, I don't know why you did that, it's not the same order than the sentence
要修正使用方法:Pattern.compile("player = new Clappr\\.Player\\(\\{source: \"(http:.*)\",.*");
使用正则表达式时，请像 regex101 一样在线尝试，并逐个单词地写正则表达式，最后您可以尝试用\ d，\ w，...替换单词/组以减少
When you use regex, try online like regex101 and write the regex like word by word, and at the end you can try to replace word/group by \d, \w,... to reduce
