How to connect http server using Swift and Alamofire - json

Question

Hi I new at swift and I got problem with server connection. I am trying to make request using a method post to login to server using username and password. How I can connect to the server and authentificate?
error messsage:
["id": <null>, "error": {
code = "-32700";
message = "Parse error";
}, "jsonrpc": 2.0]
Code:
class ViewController: UIViewController {
override func viewDidLoad() {
var userName = "root"
var password = "admin01"
// http://192.168.1.1/ubus
//var LOGIN_TOKEN = 0000000000000000
let url: String = "http://192.168.1.1/ubus"
let param: [String: Any] = ["username": "admin", "password": "admin01", "token": "0000000000000000"]
Alamofire.request(url, method: .post, parameters: param,
encoding: JSONEncoding.default)
.responseJSON { response in
guard response.result.error == nil else {
// got an error in getting the data, need to handle it
print("error calling post")
print(response.result.error!)
return
}
// make sure we got some JSON since that's what we expect
guard let json = response.result.value as? [String: Any] else {
print("didn't get todo object as JSON from API")
print("Error: \(response.result.error)")
return
}
print(json)
}
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
Json at server which I need to get:
{"jsonrpc":"2.0","id":1,"result":[0,{"ubus_rpc_session":"07e111d317f7c701dc4dfde1b0d4862d","timeout":300,"expires":300,"acls":{"access-group":{"superuser":["read","write"],"unauthenticated":["read"]},"ubus":{"*":["*"],"session":["access","login"]},"uci":{"*":["read","write"]}},"data":{"username":"root"}}]}
Request should look like:
"{ \"jsonrpc\": \"2.0\", \"id\": 1, \"method\": \"call\", \"params\": [ \"00000000000000000000000000000000\", \"session\", \"login\", { \"username\": \"root\", \"password\": \"admin01\" } ] }"

Try to use this code:
Alamofire.request(url, method: .post, parameters: parameters).responseJSON { response in
if(response.result.isFailure){
print("no data!");
}else{
print("received data!");
// make sure we got some JSON since that's what we expect
guard let json = response.result.value as? [String: Any] else {
print("didn't get todo object as JSON from API")
print("Error: \(response.result.error)")
return
}
print(json)
}
}
