Заголовки HTTP с NSURLRequest в swift
У кого-нибудь есть идея, как настроить HTTP-заголовки с NSURLRequest в Swift? У меня настроена аутентификация на моем сервере, и ему нужен только токен, переданный ему, но у меня возникли проблемы с настройкой заголовка
мой код:
func getLatestData() {
var loggedInUsersNumber:String = SharingManager.sharedInstance.userID
var usersDataPoint:String = StormDataPoint + loggedInUsersNumber
activityIND.hidden = false
activityIND.startAnimating()
let request = NSURLRequest(URL: NSURL(string: usersDataPoint)!)
let tokenString = SharingManager.sharedInstance.authToken
//request.setValue("Token " + tokenString, forKey: "Authorization")
let urlSession = NSURLSession.sharedSession()
let task = urlSession.dataTaskWithRequest(request, completionHandler: {
(data, response, error) -> Void in
if let error = error {
print(error)
return }
Я создал свойство "tokenString", чтобы быть токеном для передачи в заголовок и в следующей строке, где я прокомментировал его. запрос.setvalue-я вставил его и получил сообщение об ошибке "невозможно переопределить тип данных". Все мои поиск показывает Objective C help. Есть ли лучший способ попытаться передать заголовок?

в Swift 3 Используйте URLRequest структура вместо NSURLRequest (аналогично, NSURL ↦ URL, NSURLSession ↦ URLSession, etc.).
затем использовать addValue(_:forHTTPHeaderField:) добавить заголовок.
// swift 3:
var request = URLRequest(url: URL(string: usersDataPoint)!)
request.addValue("Token \(tokenString)", forHTTPHeaderField: "Authorization")
в Swift 2.2, вы используете NSMutableURLRequest если вам нужно, чтобы изменить его.
// swift 2:
let request = NSMutableURLRequest(URL: NSURL(string: usersDataPoint)!)
request.addValue("Token \(tokenString)", forHTTPHeaderField: "Authorization")
вы можете создать изменяемый запрос URL, а затем установить значение для имени Поля.
let request = NSMutableURLRequest(URL: NSURL(string: yourURLString)!)
request.setValue("\(yourValue)", forHTTPHeaderField: "Header-field-name")
Swift3 больший пример
var req: URLRequest = /* create requets */
req.setValue("Bearer Y3GzLG2x6wSXihmUGhwGFw", forHTTPHeaderField: "Authorization")
req.timeoutInterval = 10
let task = URLSession.shared.dataTask(with: req, completionHandler: { (data, response, error) in
print("completionHandler invoked")
})
