未能與API調用來登錄並不能保存訪問ID

Question

這就是我的工作我的第一個應用程序。筆者對登錄調用函數API網址。而當我輸入用戶名，密碼。它會生成一個客戶ID。而我需要保存的是，我必須使用該特定的ID爲我的所有屏幕，直到用戶註銷。

但是，當我在做什麼API調用登錄。它不工作。請幫助我。

這是我的參數傳遞：

{ 
    "username" : "u@gmail.com", 
    "password" : "u123" 
} 

登錄API調用後，我的JSON輸出：

{ 
    "status": 1, 
    "message": "Login success.", 
    "CustomerDetails": { 
    "CustomerId": "1", 
    "CustomerName": "u", 
    "CustomerEmail": "u@gmail.com", 
    "CustomerMobile": "901", 
    "CustomerAddress": "#45, 7th main road." 
    } 
} 

在這方面，我需要保存CustomerId，我必須使用CustomerId我所有的屏幕。

我的API調用機能的研究，同時登錄按鈕，輕按：

請幫助我。

func apicalling() { 

    let Username:NSString = EmailTextField.text! as NSString 
    let password:NSString = PasswordTextField.text! as NSString 

    let headers = [ 
     "content-type": "application/json", 
     "cache-control": "no-cache", 
     "postman-token": "4c933910-0da0-b199-257b-28fb0b5a89ec" 
    ] 
    let parameters = [ 
      "username": "\(Username)", 
      "password": "\(password)" 
    ] 
    do { 
     let postData = try JSONSerialization.data(withJSONObject: parameters, options :[]) 
     let request = NSMutableURLRequest(url: NSURL(string: "http://Login.php")! as URL,cachePolicy: .useProtocolCachePolicy,timeoutInterval: 10.0) 
     request.httpMethod = "POST" 
     request.allHTTPHeaderFields = headers 
     request.httpBody = postData 

     let session = URLSession.shared 
     let dataTask = session.dataTask(with: request as URLRequest, completionHandler: { (data, response, error) -> Void in 
      if (error != nil) { 
       ///print(error) 
      } else { 

      DispatchQueue.main.async(execute: { 

      if let json = (try? JSONSerialization.jsonObject(with: data!, options: [])) as? Dictionary<String,AnyObject> 
        { 
         let status = json["status"] as? Int; 
         if(status == 1) 
         { 
          print(json) 
          } 

        } 
       }) 
      } 
     }) 

     dataTask.resume() 



    } catch { 
     // print("JSON serialization failed: \(error)") 
    } 
} 

代碼保存在數據NSUserDefaults的。

let userDefaults = NSUserDefaults.standardUserDefaults() 
userDefaults.setValue(YOUR_VALUE, forKey: "PASSKEY") 
userDefaults.synchronize() // don't forgot this line  

NSUserDefaults的從

if let VARIABLE = userDefaults.valueForKey("PASSKEY") { 
    // do something here when a Data exists 
} 
else { 
    // no data exists 
}
