Solution to garbled Chinese characters stored in jsp cookies

The solution is as follows:

You can use java.net. URLEncoder. encode () to encode the Chinese characters to be passed.

A. Transcode the parameter before passing the parameter: java.net. URLEncoder. encode (param );

Use the statement java.net. URLDecoder. decode (param) to return the value to Chinese.

For example, set cookie

The code is as follows:	Copy code
<% String str = "this is a Chinese cookie value "; Cookie c = new Cookie ("str", java.net. URLEncoder. encode (str )); C. setMaxAge (24*3600 ); // Add a cookie object to the client Response. addCookie (c ); %>

Accept cookie:

 

The code is as follows:	Copy code
<% Request. setCharacterEncoding ("UTF-8 "); Cookie [] cookies = request. getCookies (); For (Cookie c: cookies)  {  // If the cookie value is 'str', you need to find it. If (c. getName (). equals ("str "))   { Out. print (java.net. URLDecoder. decode (c. getValue ()));   }  } %>

The url values below are garbled in Chinese.

Jump page:

<A href = info. jsp? Info = "<% = java.net. URLEncoder. encode (" Chinese character "," GBK ") %>"> Jump </a>

Receiving page
