Ajax Chinese garbled problem

<%@ page contenttype= "text/html;charset=gb2312%>
If you use a servlet, add
Response.setcontenttype ("text/html;charset=gb2312");
Request.setcharacterencoding ("gb2312");
And a better way is to add a filter
in which to join
Response.setcontenttype ("text/html;charset=gb2312");
Request.setcharacterencoding ("gb2312");
Everything's settled.

Again, uploading data from the client must be encoded at the server.
string param = Request.getparamter ("param");
param = new String (Param.getbytes ("iso-8859-1"), "gb2312");

It's all in Chinese now.

Note that the front and rear coding is consistent. You use Chinese. and Ajax transmits data with Utf-8.

<script>
var oxmlhttp = new ActiveXObject ("Microsoft.XMLHTTP");
Oxmlhttp.open ("Get", "ASP tutorial x.cc/content.aspx" >http://dotnet.aspx.cc/content.aspx ", false);
Oxmlhttp.send ()
var ostream = new ActiveXObject ("ADODB.stream");
if (ostream = null)
Alert ("Your machine does not support ADODB.stream.")
Else
{
ostream.type=1;
ostream.mode=3;
Ostream.open ();
Ostream.write (Oxmlhttp.responsebody);
ostream.position= 0;
Ostream.type= 2;
Ostream.charset= "gb2312";
var result= ostream.readtext ();
Ostream.close ();
Ostream = null;
alert (result);
}
</script>

The encoding for the client file is set to gb2312, as shown in the following code:

HTML code
<meta http-equiv= "Content-type" content= "text/html; charset=gb2312 "/>
Do not use the escape function to encode the query string in the URL address that is sent or the content of the request sent using the Post method, remember!

The JSP tutorial file on the server side is also set to the GB2312 encoding format, as shown in the following code:

JSP code

or set the header of the response, as shown in the following code:

Java code
Response.setheader ("Content-type", "text/html; charset=gb2312");
The two principles are the same.

The most important thing to do is to recoding the fetch string when getting the parameters, as shown in the following code:

　　

Java code
String username = new String (Request.getparameter ("username"). GetBytes ("Iso8859_1"), "gb2312");
Where the username is the received parameter.

Direct use of out.print (username), you can return the Chinese to the client, the client directly using the Xmlhttp.responsetext attribute can directly use the returned Chinese!

In the appendix, I tested a small example, in tomcat6.0 and resin2.1.8 pass the test!

  In fact, there is a solution that is once and for all, adding a filter.
The code
String username = new String (Request.getparameter ("username") is added when the Commit method is written at the server for Get time. GetBytes ("iso8859_ 1 ")," gb2312 ");   
as it should when post
string username = new String (Request.getparameter (" username "). GetBytes ("Iso8859_1"), "Utf-8");
