The solution to writing Chinese garbled characters to cookies in JSP

If the processing of Chinese in jsp is a little bad, garbled characters may appear. Now I will introduce to you the implementation program of writing Chinese to cookies in jsp. Friends who need to know can refer to it.

Cookie cannot directly store Chinese, Chinese must be encoded into asccii strings, you can do this (http://www.javaweb.cc collection and sorting) The

code is as follows
String str = java.net.URLEncoder.encode(Chinese);

after getting the encoding The string is
taken out and decoded like this: the
code is as follows
String str = java.net.URLDecoder.decode (encoded string); the

specific method

is generally such a process of string transcoding == "stored in cookie ===" read Take cookie=="Transcoding=="Display the

first step: encode first when writing a cookie

The code is as follows
Cookie cookie=new Cookie("groupMembersList",URLEncoder.encode (groupMembersList,"GBK")); //The default is Temporary Cookie, MaxAge<0
//cookie.setMaxAge(-1);
response.addCookie(cookie);


Step 2: Read the cookie and then decode the

code as follows
<%
Cookie[] cookies=request.getCookies();
for( Cookie cookie:cookies){
if(cookie.getName().equalsIgnoreCase("groupMembersList"))
request.setAttribute("group",URLDecoder.decode(cookie.getValue(),"GBK"));
}
%>

<c:out value="${requestScope.group }"/>

还有一种办法

代码如下
try{
Cookie cookie = new Cookie(name, new String(value.getBytes("GBK"), "ISO8859-1"));
cookie.setDomain(this.domain);
cookie.setPath("/");
cookie.setMaxAge(120 * 1000);
response.addCookie(cookie);
}catch (Exception e){
e.printStackTrace();
}
