JMeter using BeanShell for correlation

The so-called Association, how many number is through the corresponding information to crawl part of the information, such as hidden or session .

to use correlation in jmeter, divide it into 2 steps:

Step 1. in the Sampler Request Add regular expression, get information,add > Post processors>regular expression Extractor;

1.1 Most of us need to intercept some of the information, you can see the source code, find the required code, and then pass regular processing, here is an example:

function is to extract the values from the usersession

1.2 Sometimes we need to extract all the response information, and we can use the following:

Step2. Add Postprocessers, select BeanShell postprocessorand proceed further.

in the BeanShell We can use Java code to handle the content of the regular extract, the general step is to receive the value of the regular expression extraction, if the value needs to be used as a parameter after Sampler, we will also save it as a variable, Convenient to call later.

continue with the usersession in the first example to illustrate:

since Post needs to be submitted in the login URL, I am saving as a variable session, the following is a call to the login URL Session value.
