JMeter BeanShell - Loop through values

Question

I try to use variables from an array as Path for HTTP Request. Path should be like this: mypath/${act_value}

String[] numbers = mylist.split(",");
String act_value;

for (int i = 1; i <= 25; i++) {
    vars.put(numbers[i], act_value);
}

mylist is given as output of an extractor, comma separated string: mylist=123,456,343,909

HTTP Request state cannot access to this variable, I get error:

java.net.URISyntaxException: Illegal character in path

Answer 1

1. Amend your code to look like:

   String myList = "123,456,343,909";
   String[] numbers = myList.split(",");
   for (int i = 0; i < numbers.length; i++) {
       vars.put("number_" + i, numbers[i]);
   }
   

2. Add ForEach Controller somewhere after this script and configure it as follows:

   • Input variable prefix: number
   • Output variable name: act_value

3. Put your HTTP Request sampler as a child of the ForEach Controller

   Your HTTP Request will be executed for each value in the myList

Also consider switching to JSR223 Test Elements and Groovy language, in the majority of cases valid Beanshell code will be valid Groovy code but performance will be much higher.
