JSON Question

How to send a POST request with BODY in swift

I'm trying to make a post request with a body in swift using Alamofire.

my json body looks like :

{
"IdQuiz" : 102,
"IdUser" : "iosclient",
"User" : "iosclient",
"List":[
{
"IdQuestion" : 5,
"IdProposition": 2,
"Time" : 32
},
{
"IdQuestion" : 4,
"IdProposition": 3,
"Time" : 9
}
]
}


I'm trying to make
let
list
with NSDictionnary which look like :

[[Time: 30, IdQuestion: 6510, idProposition: 10], [Time: 30, IdQuestion: 8284, idProposition: 10]]


and my request using Alamofire looks like :

Alamofire.request(.POST, "http://myserver.com", parameters: ["IdQuiz":"102","IdUser":"iOSclient","User":"iOSClient","List":list ], encoding: .JSON)
.response { request, response, data, error in
let dataString = NSString(data: data!, encoding:NSUTF8StringEncoding)
println(dataString)
}


The request has an error and I believe the problem is with Dictionary list, cause if I make a request without the list it works fine, so any idea ?




I have tried the solution suggested but I'm facing the same problem :

let json = ["List":list,"IdQuiz":"102","IdUser":"iOSclient","UserInformation":"iOSClient"]
let data = NSJSONSerialization.dataWithJSONObject(json, options: NSJSONWritingOptions.PrettyPrinted,error:nil)
let jsons = NSString(data: data!, encoding: NSUTF8StringEncoding)



Alamofire.request(.POST, "http://myserver.com", parameters: [:], encoding: .Custom({
(convertible, params) in
var mutableRequest = convertible.URLRequest.copy() as! NSMutableURLRequest
mutableRequest.HTTPBody = jsons!.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)
return (mutableRequest, nil)
}))
.response { request, response, data, error in
let dataString = NSString(data: data!, encoding:NSUTF8StringEncoding)
println(dataString)
}

Answer

You're close. The parameters dictionary formatting doesn't look correct. You should try the following:

let parameters: [String: AnyObject] = [
    "IdQuiz" : 102,
    "IdUser" : "iosclient",
    "User" : "iosclient",
    "List": [
        [
            "IdQuestion" : 5,
            "IdProposition": 2,
            "Time" : 32
        ],
        [
            "IdQuestion" : 4,
            "IdProposition": 3,
            "Time" : 9
        ]
    ]
]

Alamofire.request(.POST, "http://myserver.com", parameters: parameters, encoding: .JSON)
    .responseJSON { request, response, JSON, error in
        print(response)
        print(JSON)
        print(error)
    }

Hopefully that fixed your issue. If it doesn't, please reply and I'll adjust my answer accordingly.
