Java - 解析URL

文章出處：URL的具體分析
建立URL String uri = "http://ice-note.blogspot.com/index.php?arg1=123&arg3=789&arg2=456"; URI aduri = new URI(uri); URL adurl = aduri.toURL(); 解析URL System.out.println("authority: " + adurl.getAuthority()); System.out.println("host: " + adurl.getHost()); System.out.println("port: " + adurl.getPort()); System.out.println("query: " + adurl.getQuery()); System.out.println("path: " + adurl.getPath()); System.out.println("file: " + adurl.getFile()); System.out.println("content: " + adurl.getContent()); System.out.println("ref: " + adurl.getRef()); 以下是我自己寫的： String arg1= null; String arg2= null; String arg3= null; String uri = "http://ice-note.blogspot.com/index.php?arg1=123&arg3=789&arg2=456"; URI aduri = new URI(uri); URL adurl = aduri.toURL(); String[] adurlArray = adurl.getQuery().split("=|&"); for (int i=0; i<adurlArray.length; i++){ if (adurlArray[i].equals("arg1")){ arg1 = adurlArray[i+1]; } if (adurlArray[i].equals("arg2")){ arg2 = adurlArray[i+1]; } if (adurlArray[i].equals("arg3")){ arg3 = adurlArray[i+1]; } }
