java中URL 的编码和解码函数

java.net.URLEncoder.encode(String s)和java.net.URLDecoder.decode(String s);

在javascript 中URL 的编码和解码函数

escape(String s)和unescape(String s) ;

在前台:

var url="test.jsp?param="+escape('this%is#te=st&o k?+/');

在后台：

String param=request.getParameter("param");

System.out.println(URLDecoder.decode(param,"UTF-8"));

javaScript中URL编码转换,escape() encodeURI() encodeURIC

avaScript中URL编码转换,escape() encodeURI() encodeURIComponent

　 在使用url进行参数传递时， 经常会传递一些中文名的参数或URL地址， 在后台处理时会发生转换错误。在有些传递页面使用GB2312， 而在接收页面使用 UTF8，这样接收到的参数就可能会与原来发生不一致。 使用服务器端的urlEncode函数编码的URL， 与使用客户端javascript的 encodeURI函数编码的URL，结果就不一样。

 

javaScript中的编码方法：

escape() 方法：
     采用ISO Latin字符集对指定的字符串进行编码。所有的空格符、 标点符号、特殊字符以及其他非ASCII字符都将被转化成% xx格式的字符编码（xx等于该字符 在字符集表里面的编码的16进制数字）。比如， 空格符对应的编码是%20。unescape方法与此相反。 不会被此方法编码的字符： @ * / +

encodeURI() 方法：

      把URI字符串采用UTF- 8编码格式转化成escape格式的字符串。 不会被此方法编码的字符：! @ # $& * ( ) = : / ; ? + '

encodeURIComponent() 方法：

      把URI字符串采用UTF- 8编码格式转化成escape格式的字符串。 与encodeURI()相比， 这个方法将对更多的字符进行编码，比如 / 等字符。所以如果字符串里面包含了URI的几个部分的话， 不能用这个方法来进行编码，否则 / 字符被编码之后URL将显示错误。不会被此方法编码的字符：! * ( )

      因 此，对于中文字符串来说，如果不希望把字符串编码格式转化成UTF-8格式的（比如原页面和目标页面的charset是一致的时候），只需要使用 escape。如果你的页面是GB2312或者其他的编码，而接受参数的页面是UTF-8编码的，就要采用encodeURI或者 encodeURIComponent。

       另外，encodeURI/encodeURIComponent是在javascript1.5之后引进的，escape则在javascript1.0版本就有。
