URL query string Chinese character problem

If the URL's query string contains Chinese characters, the Request.getparameter method does not get the correct information without special handling, due to the following two mechanisms

• The browser automatically encodes the special characters in the URL, such as requesting a localhost:8080/testjsp/loginmiddle.jsp?name= test, and the URL that is actually requested is localhost:8080/testjsp/ loginmiddle.jsp?name=%e6%b5%8b%e8%af%95, where the browser automatically makes a URL encoding based on UTF-8 (page-based encoding settings) for the Chinese language
• When Web server (Tomcat) receives the link, it will decode the URL, removing "%" and decoding by default by ISO8859-1 encoding

There are two ways to get the right information

1. Change the tomcat configuration so that it decodes the special characters of the URL by default by UTF-8

   <port= "8080"  protocol= "http/1.1"             connectiontimeout  = "20000"             redirectport= "8443"             uriencoding= "UTF-8"  />

2. Do the following when you get information

   String text = new String (Request.getparameter ("name"). GetBytes ("Iso8859-1"), "UTF-8");
