How to extract values from one Http request and pass as an array to the next Http Request In Jmeter

Question

I have a list of order number's that I have got from one HTTP request.I need to extract all these numbers and use in my next HTTP request passing as an array

Answer 1

Your question is not very clear, in order to provide exact steps we need:

1. Full (or partial) response for 1st request
2. Exact format of parameter for 2nd request.

In the meantime here is how you can extract the whole response into a JMeter Variable so you will be able to re-use it somewhere else:

1. Add Regular Expression Extractor as a child of the request which response you need to extract

2. Configure it as follows:

   • Reference Name: anything meaningful, i.e. response
   • Regular Expression: (?s)(^.*) (see How to Extract Data From Files With JMeter article for the regex explanation if needed)
   • Template: $1$

3. That's it, now you will be able to use the response from the previous request as ${response} where required.

Answer 2

Step 1: Add a post processor regular expression extractor to your get Http request and extract all order Ids .Use Match no -1 to store all order Ids.Assume that the name of the created variable is "Orders"

Step 2: Add a Beanshell pre-processor to your Post HTTP request and add the following code to the preprocessor

int count = Integer.parseInt(vars.get("Orders_matchNr"));

String delimiter = ",";
StringBuffer sb = new StringBuffer();
for(int i=1;i<=count;i++) { 
sb.append(vars.get("Orders_" + i));
if (i == count){
break; //to eliminate comma after the array
 }else {
 sb.append(delimiter);
 }
}
vars.put("arrayOutPut",sb.toString());

use [${arrayOutPut}] to pass as an array
