How to convert plain text into hexadecimal and octal formats in Loadrunner?

I already have explained how to use web_convert_param function. In this post I will write about how to convert plain test to hexadecimal format. I once used this for encoding a string.

char *PlaintoHexadecimal(const char *InputS, char *OutputS)

{   

                int i;

                char CurrentChar;

                char CurrentStr[4] = {0};   

               

                OutputS[0] = '\0'; 

                for (i = 0; CurrentChar = InputS[i]; i++)  

                {

                                sprintf(CurrentStr, "%X", CurrentChar);          

                                strcat(OutputS, CurrentStr);   

               

                } 

            return OutputS;

               

}

Action()

{

   

char InputS[] = "This is plain string";

char OutputS[100];

lr_output_message("The input is %s",InputS);

lr_output_message("The output is %s", PlaintoHexadecimal(InputS, OutputS));

return 0;

}

Once you execute the above code, the string will be converted to hexadecimal format as shown below:

Wow Done!!!! Now how to convert the plain text in octal format?

Just change the X factor to o factor ;). I am not kidding. You just have to change the below string

sprintf(CurrentStr, "%X", CurrentChar);        to     sprintf(CurrentStr, "%o", CurrentChar);          

Hope you will execute that and see what happens. I got this:

Thank you so much for reading and following.

How to convert plain text into URL format in Loadrunner?

Sometimes while parametrization and correlation we need to put a check on the type of value that is being passed. And we need to convert the format of the variable. For this we have a function in LoadRunner web_convert_param this function either converts HTML text to plain text or URL, or converts plain text to URL.

The syntax of web_convert_param is as:

int web_convert_param( const char *ParamName, [char *SourceString] char *SourceEncoding, char *TargetEncoding, LAST );

In the below example we are converting string "Plain text to be converted to URL" to URL format from plain format.

Example:

Action()

{

char param1[]="Plain text to be converted to URL";

lr_save_string(param1, "Input");

lr_output_message("The value of input is : %s",lr_eval_string("{Input}"));

web_convert_param("Input","SourceEncoding=PLAIN","TargetEncoding=URL", LAST );

lr_output_message("The value after converting is : %s",lr_eval_string("{Input}"));

return 0;

}

The output will be as :

 The following table shows same content in the three formats :

HTML	URL	Plain Text
&lt;mytag&gt;&amp;	%3Cmytag%3E%26	<mytag>&

That’s all for today :). Thanks for reading guys!!!

How to encrypt a string in Loadrunner using password encoder? How to use the encrypted value in script?

Suppose you face a situation, when you want to encrypt your password and use this value in script. This is a cake walk.

You have to go to password encoder, the Password Encoder tool lets you enter regular text and convert it to an encoded string.

Choose Start > Programs > LoadRunner > Tools >Password Encoder to open the Password Encoder tool.

Password: Enter the password you want to encode, and then click Generate.

Encoded string: Displays the encoded password string.

Generate: Generates an encoded string after a password is entered.

Copy: Copies the encoded password string to the clipboard.

Done!!!

Now, How to use the encrypted value in script?

This is done by using lr_decrypt function as shown below in script.

vuser_init()

{

    web_set_proxy("oregon:8080");

    web_set_user("oregon_user",

    lr_decrypt("518a296870b8b8d477e2f63cbbe5f2a0")," oregon:8080");

    web_url("web_url",

        "URL=http:// oregoncity.com /",

        "TargetFrame=",

        "Resource=0",

        "Referer=",

        LAST );

}
