javascript 中对于参数编码: url=encodeURI(url); 服务器端获取参数后解码: String linename = new String(request.getParameter("name").getBytes("ISO-8859-1"),"UTF-8"); 或: url=encodeURI(encodeURI(url)); //用了2次encodeURI 服务器端获取: String linename = request.getParameter(name); //java : 字符解码 linename = java.net.URLDecoder.decode(linename , "UTF-8"); OK,输出正常.
