Following are the different ways to manipulate the HTTP Request/Response:

• Get/Update Http URL:

  m.getURL(“http://oracle.com”)
  m.setURL(“http://oracle.com”)

• Get/Update Http Method:

  m.getMethod()
  m.setMethod(“POST”)

• Get/Update Http Status Code:

  m.getHttpStatusCode() 
  m.setHttpStatusCode(201) 

• Get/Add/Update/Delete Header:

  m.header("Content-Type")  OR m.header(m.GET,"Content-Type"")
  m.header(m.ADD,"Content-Type","application/xml")
  m.header(m.UPDATE,"Content-Type","application/xml")
  m.header(m.DEL,"Content-Type","application/xml") 

• Get/Add/Update/Delete Body:

  m.body("tai:tac") OR m.body(m.GET"tai:tac") 
  m.body(m.ADD,     "tai:tac","000001")
  m.body(m.UPDATE, "tai:tac:mnc","281")
  m.body(m.DELETE, "nf-id","28145") 

• Converting JSON to XML:

  m.header(m.UPDATE,"Content-Type","application/xml") 

• Converting XML to JSON:

  m.header(m.UPDATE,"Content-Type","application/json")

• Regular Expression:

     rule "iwf_test_rule40_3"
             salience 20
             when
                    m : IWFHttpResponse(body("company[1]:x") matches "[^A-Za-z]")
             then
                    m.body(m.ADD, "company[2]:y", "sap")
                    m.header(m.UPDATE, "Content-Type", "application/json")
             end

• Other Primitive DataTypes (like int, float...):

    rule "iwf_test_rule40_4"
            salience 20
            when
                   m : IWFHttpRequest( body("nf-id") == 0.001)
            then
                 m.body(m.ADD, "company[2]:y", 1)
                 m.header(m.UPDATE, "Content-Type", "application/json")
            end

• Using Functions:
  • Function Definition:

     function String charLength(String name) {  
                       return name.length();
                } 

  • Function Invoked:

    rule "iwf_test_rule40_6"
              salience 20
              when
                         m : IWFHttpRequest(charLength(body("nf-id")) == "ORACLE")
             then
                        m.body(m.ADD, "company[2]:y", 1000)
            end
