Node js Express js how to access json objects in POST method rawbody

How to request the data from rawbody as shown as JSON objects.

This is the my JSON values in rawbody See this Picture if you can't understand

{
 "startdate" : "2017-05-28T09:00:00+05:30",
 "endddate" : "2017-05-28T09:30:00+05:30",
 "event" : "Meeting",

    "pickup" , "drop"
   ],

    "from" : "vergeenia",

My Express js Code is:

app.post('/trip' , function(req , res){
    var event = req.rawBody.event; 
    var type = req.rawBody.type; 
    var name = req.rawBody.name;
    var address = req.rawBody.address;

    var jsonresult = {
         status : 'ok',
         message : event + 'Created Successfully'
       };
    res.json([json]);

})

Please help me... Thanks
