JSON data not parsing using with Alamofire in swift3 - ios

Question

I have to parse json using alamofire
before am using json session its working fine getting data from the json. now am try to parse json using alamofire.
this is the code parse the json using json, this code working fine
func auth(_ email:String,password:String) {
var request = URLRequest(url:AppConstants.apiURLWithPathComponents("usersignin"))
let session = URLSession.shared
request.httpMethod = "POST"
let bodyData = "email=\(email)&passCode=\(password)&deviceType=iOS&deviceId=\(deviceToken)"
request.httpBody = bodyData.data(using: String.Encoding.utf8);
let task = session.dataTask(with: request, completionHandler: { (data, response, error) in
do {
if data != nil {
if let jsonData = try JSONSerialization.jsonObject(with: data!, options: JSONSerialization.ReadingOptions.mutableContainers) as? NSDictionary {
errorCode = String(describing: jsonData["errorCode"]!)
msg = jsonData["msg"] as! String
print(errorCode)
print(jsonData)
if(errorCode == "1"){
DispatchQueue.main.async(execute: {
self.activityIndicator.stopAnimating()
})
} else {
self.name = jsonData.value(forKey: "name") as! String
if let kidsURLDetails = jsonData["kidsURLDetails"] as? NSArray {
for i in 0 ..< kidsURLDetails.count {
if kidsURLDetails[i] is NSDictionary {
let url = kidsURLDetails[i] as? NSDictionary
self.urls.append((url?["url"]) as! String)
}
}
}
self.serverURL = self.urls.joined(separator: ",")
print("ServerURL \(self.serverURL)")
let prefs:UserDefaults = UserDefaults.standard
prefs.setValue(self.name, forKey: "NAME")
DispatchQueue.main.async(execute: {
UIApplication.shared.endIgnoringInteractionEvents()
let controllerId = "NavID"
let storyboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
let initViewController: UIViewController = storyboard.instantiateViewController(withIdentifier: controllerId) as UIViewController
self.present(initViewController, animated: true, completion: nil)
})
}
}
} else {
}
} catch let err as NSError {
print("JSON Error \(err)")
}
})
task.resume()
}
in above code I used post method with passing parameters, when I am trying post method with parameter passing in almofire am getting error "Extra argument 'method' in call", username and password coming from textfield so after enter the email and password I have pass the parameters using post method.
this is the code I will implemented in to alamofire json parse
var request = URLRequest(url:AppConstants.apiURLWithPathComponents("usersignin"))
let bodyData = "email=\(username)&passCode=\(passcode)&deviceType=iOS&deviceId=123456"
let deviceId = "1234"
let params: [String: Any] = ["email": username, "passCode": passwordstring, "deviceType": "IOS","deviceId":deviceId]
Alamofire.request(request, method: .post, parameters: params, encoding: JSONEncoding.default, headers: nil)
.responseJSON { response in
print(response.result.value as Any) }
if I can try this code working
Alamofire.request("http://www.kids.com/rk/api/usersignin?email=demo#kidsapp.com&passCode=123456&deviceType=&deviceId=", method: .post, parameters: nil, encoding: JSONEncoding.default, headers: nil)
.responseJSON { response in
print(response.result.value as Any) }
how can I parse the json post method passing parameters using alamofire. where I did mistake pls help me

Answer 1

You are passing wrong type in 1 param in call it should be URLConvertible(string or URL) not URLRequest. try below code.
let params: [String: Any] = ["email": username, "passCode": passwordstring, "deviceType": "IOS","deviceId":deviceId]
let url = URL(string: "http://www.kids.com/rk/api/usersignin")!
Alamofire.request(url, method: .post, parameters: params, encoding: JSONEncoding.default, headers: nil)
.responseJSON { response in
}
____________Edit___________
here header is post request headers(if any) or nil
let params: [String: Any] = ["email": username, "passCode": passwordstring, "deviceType": "IOS","deviceId":deviceId]
let urlString = "http://www.kids.com/rk/api/usersignin"
guard let url = URL(string: urlString), var request = try? URLRequest(url: url, method: .post, headers: header) else{
//
return
}
request.httpBody = params.map{ "\($0)=\($1)" }.joined(separator: "&").data(using: .utf8)
Alamofire.request(request).responseJSON { response in
}

Answer 2

If you need to send the parameters in url with post request you should use URLEncoding.default encoding rather than JSONEncoding.default. JSONEncoding is used when you need to send JSON data as body with content type application/json.
Change your code like:
Alamofire.request(url, method: .post, parameters: params, encoding: URLEncoding.default, headers: nil).responseJSON { response in
print(response.result.value as Any)
}
Or you can remove encoding parameter as URLEncoding is the default encoding of Alamofire.

Answer 3

// URL
let urlString = “URL_Here”
var params = [String: Any]()
//Contruct your params
params = ["email": username, "passCode": passwordstring, "deviceType": "IOS","deviceId":deviceId]
// Request
Alamofire.request(urlString, method: .post, parameters: params, encoding: JSONEncoding.default, headers: nil)
.validate(statusCode: 200..<300)
.responseJSON { response in
if (response.result.error == nil) {
let value = response.result.value
print(value)
}
else {
let errorString = response.result.error
print(errorString)
}
}
