Summary on the method of passing Chinese characters behind the URL

Test environment:
Server tomcat5.0,
Development tool Myeclipse6.5,
Filter has been configured, encoding utf-8.

Method 1: Modify Tomcat configuration

Assume that the web service uses 8080 as the port, modify /conf/server.xml, and add the red paragraph
3793d042d9bb902f2d17c16e36523ded

Pass value code

Jsp code

var url= "/yourwebapp/test.do?field1=测试例子";  
window.open(url, "", "toolbar=no,location=no,status=no,menubar=no,scrollbars=yes,resizable=no,top=192,left=256,width=650,height=350");

Get value code

Java code

String field1=request.getParameter("field1");  
if(null == field1)  
{  
    field1=request.getParameter("field1").trim();  
  
}

Method 2: Use java.net.URLEncoder and java.net.URLDecoder
Assuming that method 1 is not used, you can use the second method.

Pass value code

Jsp code

var url= "/yourwebapp/test.do?field1=<%=java.net.URLEncoder.encode("测试例子","UTF-8")%>";  
window.open(url, "", "toolbar=no,location=no,status=no,menubar=no,scrollbars=yes,resizable=no,top=192,left=256,width=650,height=350");

Get value code

Java code

String field1=request.getParameter("field1");  
if(null == field1)  
{  
    field1=request.getParameter("field1").trim();  
    field1=java.net.URLDecoder.decode(field1,"UTF-8");  
    //tomcat默认使用ISO-8859-1进行URLEncoding,需要将其转换成我们需要的编码  
    field1=new String(field1.getBytes("ISO-8859-1"),"UTF-8");  
}
