java中URLEncode和URLDecode

URLEncode和URLDecode用于完成普通字符串和 application/x-www-from-urlencoded MIME字符串之间的相互转化  

如果传递的字符串中包含非西欧字符的字符串，会被转化成%XX%XX   XX为十六进制的数字

try {
            // 将application/x-www-from-urlencoded字符串转换成普通字符串
            String keyWord = URLDecoder.decode("%C4%E3%BA%C3", "GBK");
            System.out.println(keyWord);  //输出你好
            // 将普通字符创转换成application/x-www-from-urlencoded字符串
            String urlString = URLEncoder.encode("你好", "GBK");  //输出%C4%E3%BA%C3

            System.out.println(urlString);
        } catch (UnsupportedEncodingException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

try {
			// 将application/x-www-from-urlencoded字符串转换成普通字符串  
			String keyWord = URLDecoder.decode("%C4%E3%BA%C3", "GBK");  
			System.out.println(keyWord);  //输出你好
			// 将普通字符创转换成application/x-www-from-urlencoded字符串  
			String urlString = URLEncoder.encode("你好", "GBK");  //输出%C4%E3%BA%C3
		System.out.println(urlString);
	} catch (UnsupportedEncodingException e) {
		// TODO Auto-generated catch block
		e.printStackTrace();
	}  </pre><br><br><p></p>
