This article mainly describes the JSP using cookies to store Chinese samples, you need friends can refer to the following
Look at the time, see the book on the use of cookies to save information, see the book cited examples are English key value pairs, I think Chinese is not the same? A try is not the same. Nonsense not much to say, directly on the code: For example, addcookie.jsp code is as follows: code as follows: <html xmlns= "http://www.w3.org/1999/xhtml" > < head> <title> add cookie</title> </head> <body> <% String name = Request.getparameter ("name"); Cookie C = new Cookie ("username", name); C.setmaxage (3600); Response.addcookie (c)//Add cookie%> </body> </html> Enter localhost:8080/webdemo/in the address bar Addcookie.jsp?name= the test name to complete the cookie Add. The following is the removal of cookies, getcookie.jsp code as follows: code as follows: <html xmlns= "http://www.w3.org/1999/xhtml" > < head> <title> add cookie</title> </head> <body> <% cookie[] cookies = Request.getcookies ()///Fetch cookie for (cookie cc:cookies)/traversal find the corresponding cookie { if (Cc.getname (). Equals (" Username ")) { OUT.PRINTLN (Cc.getvalue ()); }}%> </body> </html> But when you enter localhost:8080/webdemo/getcookie.jsp in the Address bar, you find an error, which is because the encoding is based on the requirements in RFC 2109, Only ASCII encoding can be included in the cookie. Then it's OK to encode the Chinese when you set up cookies. The improved code is as follows: code is as follows: <% String name = Request.getparameter ("name"); byte[] Rawname = name.getbytes ("iso-8859-1"); String strName = new String (Rawname, "GB2312"),//Get parameter in Chinese string form Cookie c = new Cookie ("username", Urlencoder.encode (strName , "UTF-8")); c.setmaxage (3600); Response.addcookie (c); %> <% cookie[] cookies = request.getcookies (); for (Cookie cc:cookies) { if (Cc.getname (). Equals ("username")) { STR ing str = urldecoder.decode (Cc.getvalue (), "UTF-8");/decoding OUT.PRINTLN (str); }%> Other local problems are not the same as in the following code, some people do different things. The code is as follows: byte[] Rawname = name.getbytes ("iso-8859-1"); String strName = new String (Rawname, "GB2312"),//Get parameter in Chinese string form Cookie c = new Cookie ("username", Urlencoder.encode (strName , "UTF-8")); I searched a lot of information,There is only a piece of code, such as: cookie C = new Cookie ("username", Urlencoder.encode ("Monkey King", "UTF-8")); Place Chinese directly in the parameter position of the Encode method, it appears that it can be directly in Name=request.getparameter ("name"), and then call the cookie c = new Cookie ("username") above. Urlencoder.encode (name, "UTF-8")); code snippet, it looks like there is no wrong, but I found in practice will produce garbled, I use Firefox browser, and then I added two pieces of code, is: byte[] Rawname = Name.getbytes ("iso-8859-1"); String strName = new String (Rawname, "GB2312"); there is no garbled, specific why the reason for this, I do not know, I do not understand which great God can explain.
