embedded - Storing an HTTP request in an array using C -

i trying catch http request , store in array using c . how can possibly ?

the request of following form :

post /box/update http/1.1 accept : application/json content-type : application/x-www-form-urlencoded host:121.158.41.104:1338 content-length : 83 connection : close  serial=1234&pin=1234&powestate=true&startstate=true&temperature=11&macadress=113 

code have tried far :

my program requires store each variable , value further use.i have been able read request , output on console , further stuck.
