使用java从文本中删除url [英] Removing the url from text using java

问题描述

如何删除文本示例中的URL

How to remove the URLs present in text example

String str="Fear psychosis after #AssamRiots - http://www.google.com/LdEbWTgD http://www.yahoo.com/mksVZKBz";

使用正则表达式？

I想要删除文本中的所有网址。但它没有用，我的代码是：

I want to remove all the URLs in the text. But it's not working, my code is :

String pattern = "(http(.*?)\\s)";
Pattern pt = Pattern.compile(pattern);
Matcher namemacher = pt.matcher(input);
if (namemacher.find()) {
  str=input.replace(namemacher.group(0), "");
}

推荐答案

输入字符串包含url

private String removeUrl(String commentstr)
    {
        String urlPattern = "((https?|ftp|gopher|telnet|file|Unsure|http):((//)|(\\\\))+[\\w\\d:#@%/;$()~_?\\+-=\\\\\\.&]*)";
        Pattern p = Pattern.compile(urlPattern,Pattern.CASE_INSENSITIVE);
        Matcher m = p.matcher(commentstr);
        int i = 0;
        while (m.find()) {
            commentstr = commentstr.replaceAll(m.group(i),"").trim();
            i++;
        }
        return commentstr;
    }
