Jmeter - combine two variables into one

Question

I have extract Json element in previous step (which created an array) and I want to access specific element inside using counter variable (inside foreach). this is the element that holds the array:

SB_names

and inside the 'Foreach' I have created a counter with variable - 'counter'. now, in the name of the http request I'm trying to access each element of the array in each iteration. this works for example:

${__V(${SB_names_1})}

but I want to do something like this (which currently is not working):

${__V(${SB_names_${counter}})} 

thanks.

Answer 1

正确的语法是：

${__V(SB_names_${counter})}

  

例如，如果有变量A1，A2和N = 1：

     

$ {A1} - 工作正常

     

$ {A $ {N}} - 无效（嵌套变量引用）

     

$ {__ V（A $ {N}）} - 工作正常。 $ {N}变为A1，__ V函数返回A1

的值
