Here is the complete code for REST API requests using NSURLSession in swift
For GET Request
let configuration = NSURLSessionConfiguration .defaultSessionConfiguration()
let session = NSURLSession(configuration: configuration)
let urlString = NSString(format: "your URL here")
print("get wallet balance url string is \(urlString)")
//let url = NSURL(string: urlString as String)
let request : NSMutableURLRequest = NSMutableURLRequest()
request.URL = NSURL(string: NSString(format: "%@", urlString) as String)
request.HTTPMethod = "GET"
request.timeoutInterval = 30
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
request.addValue("application/json", forHTTPHeaderField: "Accept")
let dataTask = session.dataTaskWithRequest(request) {
(let data: NSData?, let response: NSURLResponse?, let error: NSError?) -> Void in
// 1: Check HTTP Response for successful GET request
guard let httpResponse = response as? NSHTTPURLResponse, receivedData = data
else {
print("error: not a valid http response")
return
}
switch (httpResponse.statusCode)
{
case 200:
let response = NSString (data: receivedData, encoding: NSUTF8StringEncoding)
print("response is \(response)")
do {
let getResponse = try NSJSONSerialization.JSONObjectWithData(receivedData, options: .AllowFragments)
EZLoadingActivity .hide()
// }
} catch {
print("error serializing JSON: \(error)")
}
break
case 400:
break
default:
print("wallet GET request got response \(httpResponse.statusCode)")
}
}
dataTask.resume()
For POST request ...
let configuration = NSURLSessionConfiguration .defaultSessionConfiguration()
let session = NSURLSession(configuration: configuration)
let params = ["username":bindings .objectForKey("username"), "provider":"walkingcoin", "securityQuestion":securityQuestionField.text!, "securityAnswer":securityAnswerField.text!] as Dictionary<String, AnyObject>
let urlString = NSString(format: “your URL”);
print("url string is \(urlString)")
let request : NSMutableURLRequest = NSMutableURLRequest()
request.URL = NSURL(string: NSString(format: "%@", urlString)as String)
request.HTTPMethod = "POST"
request.timeoutInterval = 30
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
request.addValue("application/json", forHTTPHeaderField: "Accept")
request.HTTPBody = try! NSJSONSerialization.dataWithJSONObject(params, options: [])
let dataTask = session.dataTaskWithRequest(request)
{
(let data: NSData?, let response: NSURLResponse?, let error: NSError?) -> Void in
// 1: Check HTTP Response for successful GET request
guard let httpResponse = response as? NSHTTPURLResponse, receivedData = data
else {
print("error: not a valid http response")
return
}
switch (httpResponse.statusCode)
{
case 200:
let response = NSString (data: receivedData, encoding: NSUTF8StringEncoding)
if response == "SUCCESS"
{
}
default:
print("save profile POST request got response \(httpResponse.statusCode)")
}
}
dataTask.resume()
I hope it works.
