希望在一行包含下载地址的字符串中找到下载地址
String source = "http:\\djfshgdfhgwma "; //s2+s1;
Pattern p = Pattern.compile( "http\\:\\w+\\.wma ");
Matcher m = p.matcher(source);
while (m.find()) {
System.out.println( "Match \ " " + m.group() + "\ " at positions "
+ m.start() + "- " + (m.end() - 1));
可是没有结果
请问为何 ? 如何处理后缀中的点号 ?
谢谢
------解决方案--------------------
Pattern p = Pattern.compile( "http:\\\\\\\\\\w+\\.wma ");
另外,你那个String source = "http:\\djfshgdfhgwma ";
是不是少了个 ". "
------解决方案--------------------
修正一下 Pattern p = Pattern.compile( "http:\\\\.*.wma ");
应该是Pattern p = Pattern.compile( "http:\\\\.+.wma ");
