Learn BeanShell before you dare to say you know JMeter

jmeter Of BeanShell Sampler, You can quote java Code , There are the following 3 Ways of planting ：

• Direct input java Code

• Import java file

• Import class file

BeanShell Script accesses variables mainly through vars  and  props To visit , Common main methods are as follows ：

• vars.get( Variable name )： Get the value corresponding to the defined variable , contain BeanShell Script generation variables ;

• vars.put( Variable name , A variable's value )： Generate new variables or modify existing variables ;

• props.get( Variable name )： obtain jmeter.properties Define the corresponding value of the variable in ;

01、 Direct input Java Code

1、 stay testplan Add variable value to

add to BeanShell Sampler, Pay attention to BeanShell One must be added before and after Debug Sampler, It should be convenient for debugging to see the result , Added Debug Sampler No need for any operation .

Run to view the execution results

2、 stay jmeter Call method used in

View results

02、BeanShell Introduction in Java file

Write a Java Save the file to the desktop

stay BeanShell Introduce the Java file

View the results of the execution

03、BeanShell Introduction in class file

View the generated results

04、BeanShell Realize encryption and decryption  

1、 stay IDEA Write the encrypted script in

2、 Then export the entire package file , Generate jar package

3、 take jar Put the package file in jmeter Of lib/ext Under the table of contents

And then in jmeter Of BeanShell This class is introduced in , Call the encryption method

View debugging results

Save the encrypted data to mdm In this variable , For jmeter Use in .
