jsp URL中文传参乱码问题

一、在请求页面的请求参数需要用encodeURI进行转码,然后在接收请求的页面需要进行字符集转换。

本例中的请求和接收页面的字符集都是UTF-8:

1.请求的JSP页面用JavaScript的encodeURI()方法将参数转码:

function toView(param){

???? var encodeparam = encodeURI(param) ;

???? window.location.href="/naias/advAna_form.do?method=showDetail&title="+encodeparam ;

}

2.在跳转的Action中进行字符集转换:

public ActionForward excute(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response){

??? String title= request.getParameter("title");
??? title= new String( title.getBytes("iso-8859-1"), "UTF-8");

??? System.out.println(title);

}

二、为编码为UTF-8的JSP页面传参，对于中文乱码的解决分为两种情况：

?

1.通过GET方式传参，通过new String(request.getParameter("").getBytes("ISO-8859-1"),"UTF-8"); 的方式转换为需要的编码，如UTF-8等。

?

2.通过POST方式传参，通过声明request.setCharacterEncoding("UTF-8");的方式声明编码类型来解决。

?

三、可以通过加过滤器，解决乱码 ，但是对GET方式提交的参数(也就是通过地址栏穿的参数)不起作用。

?

四、如果用tomcat服务器，可以更tomcat的配置文件将字符集编码设置为UTF-8即可。

?

以上方法都不行的话，提供如下绝对行的方法：

直接给代码吧，把如下代码copy到Escape.java文件中

[java] view plaincopy
  1. package?com.ctgusec.oaPlus;??????
  2. /**????
  3. ?*?将url中文参数编码或者反编码????
  4. ?*?javascript?escape/unescape?编码的?Java?实现????
  5. ?*?author?agile????
  6. ?*?使用方法：?
  7. ?*?Escape.unescape(vaule);//导入这个java文件，调用unescape方法，参数为js提交过来的16进制字符串?
  8. ?*?js页面提交url方法：?
  9. ?*?escape()?是JavaScript函数，对字符串转码，解决中文参数问题?
  10. ?*?URL:servlet?属性="+escape(escape(str)?;//参数str是需要提交的中文字符?

?以上代码做的工作是把通过js获取的字符串转换成16进制的字符串放到url的参数上，传到服务器端再把这个16进制字符串转换为原来的字符串。
