posting JSON object to a Restful web service

Question

I have two Restful web services:
service1: api.wego.com/flights/api/k/2/searches and
service2: api.wego.com/flights/api/k/2/fares

service1's question:
I want to use AFJSONRequestOperation to do a POST request to serivce1 , the using of AFJSONRequestOperation instead of RestKit with this service is because I don't need to create any mapping for the returned response, I simply just want to save some of the returned data into local variables, but the problem is that service1 expects something like this JSON in the post body:

{
"trips": [ {
"departure_code": "SIN",
"arrival_code": "HKG",
"outbound_date": "2013-11-29",
"inbound_date": "2013-12-06"
} ],
"adults_count": 1
}

the question: how to create an AFJSONRequestOperation to post a request to service1 and send the above JSON with the post body ?

service2's question:
I want to use RestKit 0.2x to do a POST request to this service, I know how to build up the mapping model, but according to the service docs, I have to send a JSON object along with the post body that looks like this:

{
"id": "1376967853520",
"search_id": "IAXutjj0TAu0Wq-kvOMK6A",
"trip_id": "NYC:LON:2013-11-29:2013-12-06",
"fares_query_type": "route"
}

I used RestKit previously to do Get requests using getObjectsAtPath method, but in this case I think I have to use postObject method to do the POST request but I'm not sure of that.

the question: how to do a POST request to service2 using RestKit 0.2x and send the above JSON with the post body (considering that the mapping model is already set and ready to be used) ?

thank you so much for your kind help.

Answer 1

1. Create a dictionary and use NSJSONSerialisation (This would produce data for you to set as the operation payload). Or, use RKObjectManager requestWithObject:method:path:parameters: (which would create the URL request to send, with the payload data already set). Then create the request operation with that.

2. Yes, use the RKObjectManager postObject:... method. You need to create request mapping and descriptor for the class of object you're going to post. Then just post with the object and path.
