Sorry if this question seems dumb, but I have query parameter (that I received via ListenHttp) in format a=value_a&b=value_b and so on, I want to convert this to json as the form given below -
"a" : "value_a",
"b" : "value_b"
I am not quite sure, but I think I should be using ReplaceText, but I am unable to understand how to write the regex. If using ReplaceText is the one I should not use on Nifi, then please do let me know how to approach the same?
