HTML Form problem with special characters

bacanoides

Hi,

I created component that generates an html form. When submitting the form with special characters in a text field (within the form), ex: portuguese characters "ã ; ç" and so on, we were not able to get those characters correctly through the RequestContext.getParameterString() method.

After getting the parameter its value contains strange characters instead of the original ones.

We also tried to decode the parameter value (using URLDecoder.decode(param, "UTF-8")), but we had no success. After decoding the result was exactly the same as the value from the RequestContext.

I think the data in the POST were encoded as you may see in the fiddler capture below, and once the request is intercepted by the server, it was decoded but with a different char-set (not the UTF-8).

This is the value inserted in the form's field:

Hugo Venâncio João Gonçalves

This is the HTTP request (intercepted by fiddler):

POST http://my-server/iw-preview/52616e646f6d4956fda2003160fb7f07825b5e36ef43308c830e70c844758b8dd621ce9fd3e6f7de4b699fcf8339965d811b2235c33edbdda4f61d47348efd4b/gf2p8ump.seed?submit=true&componentID=1285683101115 HTTP/1.1 Host: my-server User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2.10) Gecko/20100914 Firefox/3.6.10 ( .NET CLR 3.5.30729) Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 115 Connection: keep-alive Referer: http://my-server/iw-preview/52616e646f6d4956fda2003160fb7f07825b5e36ef43308c830e70c844758b8dd621ce9fd3e6f7de4b699fcf8339965d811b2235c33edbdda4f61d47348efd4b/gf2p8ump.seed Content-Type: application/x-www-form-urlencoded Content-Length: 211 isClient=S&clientName=Hugo+Ven%C3%A2ncio+Jo%C3%A3o+Gon%C3%A7alves

This is the parameter value from the RequestContext:

key(clientName)=value[Hugo Venâncio João Gonçalves]:class[java.lang.String]

I'm using Win2008 Server + Interwoven TS / LS 7.1.

Please help.
Thanks in advance.

Best regards,
Luis

I had faced the same issue and I solved it by getQueryString() instead of getParameterString().

May be this code will help you...

String tempQuery = (String) context.getRequest().getQueryString();

if ((null != tempQuery)
&& ("" != tempQuery))
{
test1= (String)GetParameters.queryStringToMap(context.getRequest().getQueryString()).get("q");
test2= (String)GetParameters.queryStringToMap(context.getRequest().getQueryString()).get("f");

}



public HashMap queryStringToMap(String queryString){
HashMap queryStringMap = new HashMap();
if(null!= queryString && !"".equals(queryString)){
if (queryString.indexOf("&")>=0) {
String[] arry = queryString.split("&");
StringTokenizer st = new StringTokenizer(queryString,"&");
while(st.hasMoreElements()){
String str = (String)st.nextElement();
if (str.indexOf("=") >= 0) {
String[] query = str.split("=");
queryStringMap.put(query[0], query[1]);
}
}
}else{
String[] query = queryString.split("=");
queryStringMap.put(query[0], query[1]);
}
}
return queryStringMap;
}
