How to POST JSON data using NSURLSession in swift - json

Question

I am stuck with the below code. How do I set the param and in post method?
let params:[String:Any] = [
"email" : usr,
"userPwd" : pwdCode]
let url = NSURL(string:"http://inspect.dev.cbre.eu/SyncServices/api/jobmanagement/PlusContactAuthentication")
let request = NSMutableURLRequest(URL: url!)
request.setValue("application/json; charset=utf-8", forHTTPHeaderField: "Content-Type")
request.HTTPBody = params<what should do for Json parameter>
let task = NSURLSession.sharedSession().dataTaskWithRequest(request) {
data, response, error in
if let httpResponse = response as? NSHTTPURLResponse {
if httpResponse.statusCode != 200 {
println("response was not 200: \(response)")
return
}
}
if error {
println("error submitting request: \(error)")
return
}
// handle the data of the successful response here
}
task.resume()

if I understand the question correctly
var configuration = NSURLSessionConfiguration.defaultSessionConfiguration()
var session = NSURLSession(configuration: configuration)
var usr = "dsdd"
var pwdCode = "dsds"
let params:[String: AnyObject] = [
"email" : usr,
"userPwd" : pwdCode ]
let url = NSURL(string:"http://localhost:8300")
let request = NSMutableURLRequest(URL: url!)
request.setValue("application/json; charset=utf-8", forHTTPHeaderField: "Content-Type")
request.HTTPMethod = "POST"
var err: NSError?
request.HTTPBody = NSJSONSerialization.dataWithJSONObject(params, options: NSJSONWritingOptions.allZeros, error: &err)
let task = session.dataTaskWithRequest(request) {
data, response, error in
if let httpResponse = response as? NSHTTPURLResponse {
if httpResponse.statusCode != 200 {
println("response was not 200: \(response)")
return
}
}
if (error != nil) {
println("error submitting request: \(error)")
return
}
// handle the data of the successful response here
var result = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.allZeros, error: nil) as? NSDictionary
println(result)
}
task.resume()
I would suggest using AFNetworking. See for example, Posting JSON data using AFNetworking 2.0.

This is how you can set parameters and send a POST request, easy approach using Alamofire.
Swift 2.2
let URL = NSURL(string: "https://SOME_URL/web.send.json")!
let mutableURLRequest = NSMutableURLRequest(URL: URL)
mutableURLRequest.HTTPMethod = "POST"
let parameters = ["api_key": "______", "email_details": ["fromname": "______", "subject": "this is test email subject", "from": "support#apple.com", "content": "<p> hi, this is a test email sent via Pepipost JSON API.</p>"], "recipients": ["_________"]]
do {
mutableURLRequest.HTTPBody = try NSJSONSerialization.dataWithJSONObject(parameters, options: NSJSONWritingOptions())
} catch {
// No-op
}
mutableURLRequest.setValue("application/json", forHTTPHeaderField: "Content-Type")
Alamofire.request(mutableURLRequest)
.responseJSON { response in
print(response.request) // original URL request
print(response.response) // URL response
print(response.data) // server data
print(response.result) // result of response serialization
if let JSON = response.result.value {
print("JSON: \(JSON)")
}
}
