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, there are addcookie.jsp code as follows:
Enter the Localhost:8080/webdemo/addcookie.jsp?name= test name in the address bar to complete the cookie addition.
The following is the removal of the cookie, getcookie.jsp code is as follows:
However, when you enter localhost:8080/webdemo/getcookie.jsp in the address bar, an error is found, because the encoding is based on the requirement in RFC 2109 that only ASCII encoding can be included in the cookie.
Then you can only encode the Chinese when you set up cookies. The improved code is as follows:
Nowhere else is the problem, as in the following code, someone does something different.
Placing Chinese directly in the parameter position of the Encode method may appear to be directly in the Name=request.getparameter ("name"), and then the cookie c = new Cookie ("username") is invoked. 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.
