How to decode URL with BeanShell?

I need to pass a parameter (part of URL) in a request for example:

"S;4;163;1;O;rAghjgjU="

But this value is extracted as a regular expression like that:

"S%3B4%3B163%3B1%3BO%3BrAghjgjU%3D"

I want to use BeanShell to decode the URL.

Solution

    1. JMeter provides __urldecode() function so if you use it like:

      ${__urldecode(S%3B4%3B163%3B1%3BO%3BrAghjgjU%3D)}

      you'll get the required value.

    2. If you still want to go for Beanshell, you can invoke URLDecoder.decode(); method like:

      String decoded = URLDecoder.decode("S%3B4%3B163%3B1%3BO%3BrAghjgjU%3D", "UTF-8");

    3. There is also __Beanshell() function which allows executing arbitrary Beanshell script, invoke it like:

      ${__BeanShell(URLDecoder.decode("S%3B4%3B163%3B1%3BO%3BrAghjgjU%3D"\, "UTF-8"),)}

      See How to Use BeanShell: JMeter's Favorite Built-in Component for more information on Beanshell scripting in JMeter, in particular pay attention to how Java and JMeter API classes are invoked from within Beanshell scripts.
