BeanShell is a lightweight scripting language written in pure java.

BeanShell Sampler can be scripted in jmeter.

There are three common built-in variables:

log

Used to print logs in jmeter.log, you can print strings, variables

log.info("hello world");

vars

Used to access jmeter thread variables, usually used to access string content, but also to access objects

vars.get()

String mykey = vars.get("keyname"); ----Get the value of the thread variable name keyname and save it in mykey

String cookie11 = vars.get("COOKIE_JSESSIONID");

vars.put()

vars.put("keyname", "value"); ----Save value to jmeter thread variable keyname

vars.put("fcy", "tester");

Thread group--Add--Sampler--Debug Sampler, run, view Debug Sampler through the result tree, you can see all saved variables

Save it to a variable so that you can use it later: fcy = vars.get("fcy"), or fcy = "${fcy}"

Note: For fcy = "${fcy}", variables can be used in this way, but attributes cannot.

Properties can only be used with props.get(), the_P function, or the_property function.

3. props

Access jmeter attribute, key and value in parameters are in string form

ymd = props.get("START.YMD"); gets the value of attribute START.YMD (script start date)

props.put("PROP1", "1234");

Store 1234 in global attribute PROP1

Note: For attribute variables (global variables), generally restart jmeter to take effect, after using props, it is best to restart jmeter.

4. Difference between thread variables and attributes:

Thread variables are local variables; attributes are global variables.

For attribute variables (global variables), generally restart jmeter to take effect, after using props, it is best to restart jmeter.
