In my scenario I make multiple HTTP requests and get multiple JSON in answers. JSON look like:
{"results":[{"visitors":123,"target":"AAA"},{"visitors":45,"target":"BBB"},{"visitors":11,"target":"CCC"}]}
How to SUM them all and get info about total visitors on targets from multiple HTTPS responses at the end e.g.
AAA - 1000 visitors
BBB - 500 visitors
CCC - 70 visitors
?
numerical aggregator for the win!
A numerical aggregator lets you to apply functions like SUM or AVG to numerical values. Numerical aggregator then returns the results in one bundle.
I’m trying to use Numerical aggregator, but I can’t aggregate them by the “target” in this JSON structure.
One of HTTP request give me 0 result, another 5, and another one 20. The order is random. I can’t group (and sum) all them by “target”.
Anyone knows how to do it?
You’ll need to use map() to create a new structure first and then use the numerical aggregator.
