We are routing to to a survey via a vxml code indicated below. In getWebAppEntryPoint method we attempt to route to BUILT url variable. This is given by the URL syntax. http://<host ip>/<method name>?parameter1=value1&parameter2=value2
XML
In the above URL if we send just one parameter we could route to the VXML without issues. If we send more than one parameter we hear the Avaya promt stating "We are experiencing technical difficulties". Is there a restriction for ampersand character (&). Is there a way to encode this URL?

Thank you

How do you get the url into the BUILDURL variable in the first place?

Via an AAOD Data Node we concatenate http://<host IP>/<method name>? and every parameter with & character

Should we get BUILTURL in getWebAppEntryPoint with a specific way to make it work?

Try to use the java API URLEncoder to encode the url.

Thank you


I am still getting the same error. How should I assign the entryPoint? Below, how I attempted: Am I missing anything?

public String getWebAppEntryPoint(com.avaya.sce.runtimecommon.SCESession mySession) {
String entryPoint="";
try {
entryPoint = encodeVXMLParams(mySession).toString();
mySession.getTraceOutput().writeln(ITraceInfo.TRACE_LEVEL_DEBUG,"Routing to VXML URL "+entryPoint);
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
if (entryPoint != null)
return checkEntryPoint(entryPoint, mySession);

return "";
}

public StringBuilder encodeVXMLParams(com.avaya.sce.runtimecommon.SCESession mySession) throws UnsupportedEncodingException{

StringBuilder queryString = new StringBuilder();
String urlStr = "http://<hostname>/<method>?";
String key = "";
String value ="";
queryString.append(URLEncoder.encode(urlStr,"UTF-8"));
queryString.append(URLEncoder.encode("BROWSERNAME","UTF-8"));
queryString.append("=");

queryString.append(URLEncoder.encode("AVP","UTF-8"));
queryString.append("&");

queryString.append(URLEncoder.encode("LANG_CODE_PARAM","UTF-8"));
queryString.append("=");

queryString.append(URLEncoder.encode("en","UTF-8"));
queryString.append("&");

queryString.append(URLEncoder.encode("ANI_PARAM","UTF-8"));
queryString.append("=");

queryString.append(encodeValue(mySession.getVariableField(IProjectVariables.ANI).getStringValue()));

queryString.append("&");
queryString.append(URLEncoder.encode("UCID","UTF-8"));
queryString.append("=");

queryString.append(encodeValue(mySession.getVariableField(IProjectVariables.UCID).getStringValue()));

queryString.append("&");
queryString.append(URLEncoder.encode("UUI_PARAM","UTF-8"));

queryString.append("=");

queryString.append(encodeValue(mySession.getVariableField(IProjectVariables.UUI).getStringValue()));

return queryString;

}
public String encodeValue(String value) throws UnsupportedEncodingException{
return URLEncoder.encode(value,"UTF-8");

}

You should first create the whole url with all the special characters such as "&" and "=". then encode the whole string.

Thank you.

It doesn't work.

If I encode only & character it works from IVR perspective. However our client mentions he cannot get the parameters. Any other idea?

It would be easier to figure out what to do if you know what the error is. If the parameters are missing, you can look into the URL or http data being sent over the wire.

The encoded URL with URLEncoder doesn't work at all. I cannot reach the VXML destination
http%3A%2F%2Fvrnvsrvy1.txhhsc.txnet.state.tx.us%2Fcf%2Fstartcall%3FBROWSERNAME%3DAVP%26LANG_CODE_PARAM%3Den%26ANI_PARAM%3D8573278880%26UCID%3D00001029981535564829%26UUI_PARAM%3DPD%2C00%3BFA%2C00010BB65B86DC1D

If I encode & and the value assigned to each parameter it results in the URL below. I can reach the VXML destination. However the client complains it cannot parse the parameters once it comes with %26.
http://vrnvsrvy1.txhhsc.txnet.state.tx.us/cf/startcall?BROWSERNAME=AVP%26LANG_CODE_PARAM=en%26ANI_PARAM=8573278880%26UCID=00001029981535564829%26UUI_PARAM=PD%2C00%3BFA%2C00010BB65B86DC1D

Do you have any idea? Thank you

You can decide the query string with the decoder, for example:

java.net.URLDecoder.decode(url, "UTF-8")

Thank you.

Not sure I understood. Did you suggest that our client should decode the parameters we sent? The VXML we are routing is not under the control of my company.


Best Regards,
Cesar

Is there any restriction in VXML Servlet node of AAOD with regards to character &? It is quite complicated to our client to change it

I need to understand this a little more. Is this vxml app you are calling from OD running on the same app server or different app server?

Thanks to both.


I tried to change the approach. In a VXML code I have: Please check the attachments. In getWebAppEntryPoint method entryPoint is equal null. It looks like my parameters are not being assigned once the value obtained from checkEntryPoint is http://<hostname>; /cf/startcall? and we do not see any parameter. Do you have any hint to see the parameters in the final URL?

Thank you,
