Привет, я очень начинаю для Swift, и я пытаюсь сделать запрос NSURLSession "Post" отправив некоторый параметр, например, мой ниже код
В соответствии с моим приведенным ниже ответом на код, который не поступает с сервера, может кто-то мне помочь.
BackGroundClass: -
import UIKit
protocol sampleProtocal{
func getResponse(result:NSDictionary)
func getErrorResponse(error:NSString)
}
class BackGroundClass: NSObject {
var delegate:sampleProtocal?
func callPostService(url:String,parameters:NSDictionary){
print("url is===>\(url)")
let request = NSMutableURLRequest(URL: NSURL(string:url)!)
let session = NSURLSession.sharedSession()
request.HTTPMethod = "POST"
//Note : Add the corresponding "Content-Type" and "Accept" header. In this example I had used the application/json.
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
request.addValue("application/json", forHTTPHeaderField: "Accept")
request.HTTPBody = try! NSJSONSerialization.dataWithJSONObject(parameters, options: [])
let task = session.dataTaskWithRequest(request) { data, response, error in
guard data != nil else {
print("no data found: \(error)")
return
}
do {
if let json = try NSJSONSerialization.JSONObjectWithData(data!, options: []) as? NSDictionary {
print("Response: \(json)")
self.mainResponse(json)
} else {
let jsonStr = NSString(data: data!, encoding: NSUTF8StringEncoding)// No error thrown, but not NSDictionary
print("Error could not parse JSON: \(jsonStr)")
self.eroorResponse(jsonStr!)
}
} catch let parseError {
print(parseError)// Log the error thrown by `JSONObjectWithData`
let jsonStr = NSString(data: data!, encoding: NSUTF8StringEncoding)
print("Error could not parse JSON: '\(jsonStr)'")
self.eroorResponse(jsonStr!)
}
}
task.resume()
}
func mainResponse(result:NSDictionary){
delegate?.getResponse(result)
}
func eroorResponse(result:NSString){
delegate?.getErrorResponse(result)
}
}
ViewController: -
import UIKit
class ViewController: UIViewController,sampleProtocal {
override func viewDidLoad() {
super.viewDidLoad()
let delegate = BackGroundClass();
delegate.self;
let params = ["scancode":"KK03799-008", "UserName":"admin"] as Dictionary<String, String>
let backGround=BackGroundClass();
backGround.callPostService("url", parameters: params)
}
func getResponse(result: NSDictionary) {
print("Final response is\(result)");
}
func getErrorResponse(error: NSString) {
print("Final Eroor code is\(error)")
}
}
