We recently encountered a situation where we were expected to simulate a forgot password retrieval functionality. Application used to send an email to registered user id and user was expected to click on link in the email to reset the password.
To avoid the hassle of retrieving email we went directly to developer to understand the logic of the link generation. The logic involved passing of a hashed value into the generated url. Hash was generated using the java hashcode upon username+password. Below is an example of java hashcode
We could not find a way to include above code in http/html scripts, hence we had to find the equivalent code of hashcode in C language.
Following code was used for this in loadrunner

import java.io.*;
public class HelloWorld{
public static void main(String []args){
String Str = new String("SPEForums.com");
System.out.println("Hashcode for Str :" + Str.hashCode() );
}
}We could not find a way to include above code in http/html scripts, hence we had to find the equivalent code of hashcode in C language.
Following code was used for this in loadrunner
Code:
Action()
{
//h is the hash value
int h = 0;
//Left offset Value
int off = 0;
//String to be hashed
char val[] = "SPEForums.com";
//Length of the string
int len = strlen(val);
//For loop
int i;
//Algo equivalant to java hashcode
for (i = 0; i < len; i++) {
h = 31*h + val[off++];
}
// hash = h; Print hash code
lr_output_message("hash is %d",h);
return 0;
