Enhancing a Recorded Session

You can prepare an XML script by recording a session and then manually adding the relevant XML and Vuser API functions.

The following example illustrates how a recorded session was enhanced with Vuser API functions. Note that the only function that was recorded was web_submit_data, which appears in bold.

The first section contains the XML input declaration of the variable SOAPTemplate, for a SOAP message:

#include "as_web.h" 

// SOAP message 

const char* pSoapTemplate =  "<soap:Envelope
         xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">" 
         "<soap:Body>" 
         "<SendMail xmlns=\"urn:EmailIPortTypeInft-IEmailService\"/>" 
         "</soap:Body>" 
         "</soap:Envelope>"; 

The following section represents the actions of the user:

Action1() 
{ 
       // get response body 

       web_reg_save_param("ParamXml", "LB=", "RB=", "Search=body", LAST); 

       // fetch weather by HTTP GET 

       web_submit_data("GetWeather",
          "Action=http://glkev.net.innerhost.com/glkev_ws/WeatherFetcher.asmx/GetWeather", 
          "Method=GET", 
          "EncType=",
