Http_read_data

i got the list from Request http_read_data.

http_read_data(Request, Data, []),
Data = [param1=value1,param2=value2]

how to use it ? how to get the value param1 ?

Data there is a list of compounds in the form key=value, so to get a particular value out, I generally use memberkchk/2. For example, memberchk(param1=Param1Val, Data).
