Resolution

Perform the following local-change:

When using a custom authentication for a service that is also using Basic Authentication, perform the following steps:
  1. Set the Authentication Service on the Custom tab to use 'Basic Authentication'
  2. Use the following java code to access the authorization header in the Authentication activity:

javax.servlet.http.HttpServletRequest request = 
    (javax.servlet.http.HttpServletRequest)tools.getRequestor().getRequestorPage().getObject("pxHTTPServletRequest");

String authHeader = request.getHeader("authorization");
if (authHeader != null){
   String base64UandP = authHeader.substring(6);
   sUserAndPass = Base64Util.decode(base64UandP);
   oLog.infoForced("UserAndPass: "+ sUserAndPass);
}
else {
  //Direct processing to error handling in step named ERR
  nextBlock = "ERR";
}



To read the payload of the data in a SOAP or REST HTTP POST request, use the following Java code in the Authentication activity to get access to the data:


javax.servlet.http.HttpServletRequest request = 
    (javax.servlet.http.HttpServletRequest)tools.getRequestor().getRequestorPage().getObject("pxHTTPServletRequest");


StringBuffer inData = new StringBuffer();
String line = null;

try{
  
    java.io.InputStream is = request.getInputStream();
    java.io.BufferedReader br = new java.io.BufferedReader(new java.io.InputStreamReader(is, "UTF-8"));
    while ((line = br.readLine()) != null){
        inData.append(line);
    } 
}catch (Exception e){
   //Direct processing to error handling in step named ERR
  nextBlock = "ERR";
}


After these steps, the content is in the StringBuffer inData and can be used further to access the content.
For example, for a JSON type data, include the data to the clipboard and use standard processing to get the data contents.

Example for JSON:


ClipboardPage inDataPage = tools.createPage("","inData");

try {
 inDataPage.adoptJSONObject(inData.toString());
String someData=inDataPage.getString("SomeDataElement");

}
