Question

我将一些Objective-c代码（带有一些更改）移植到swift中，并且没有“private”的链接有效，而另一个则没有。这就是我所拥有的：

import Cocoa

class MasterViewController: NSViewController, NSURLSessionDataDelegate {
  var session: NSURLSession!
  var courses: JSON!

  override func viewDidLoad() {
    super.viewDidLoad()

    let config: NSURLSessionConfiguration? =
    NSURLSessionConfiguration.defaultSessionConfiguration()

    session = NSURLSession(configuration: config, delegate: self, delegateQueue: nil )
    fetchFeed()
  }

  func fetchFeed() {
    let requestString: String = "https://bookapi.bignerdranch.com/courses.json"
    // let requestString: String = "https://bookapi.bignerdranch.com/private/courses.json"
    if let url: NSURL? = NSURL(string: requestString) {
      let request: NSURLRequest = NSURLRequest(URL: url!)
      let dataTask : NSURLSessionDataTask = session.dataTaskWithRequest(request, completionHandler: {(data, response, error) in
        var jsonObject: [JSON] = JSON(data: data).arrayValue

        self.courses = JSON(data: data)

        dispatch_async(dispatch_get_main_queue(), { _ in
          println( self.courses?.debugDescription )
        })
      });
      dataTask.resume()
    }
  }

  func URLSession(session: NSURLSession, didReceiveChallenge challenge: NSURLAuthenticationChallenge, completionHandler: (NSURLSessionAuthChallengeDisposition, NSURLCredential!) -> Void) {
    var userIdString: String = "BigNerdRanch"
    var passwordString: String = "AchieveNerdvana"
    println( "Received challenge, responding with UID: \(userIdString) PWD: \(passwordString)")
    var cred: NSURLCredential = NSURLCredential(user: userIdString,
      password: passwordString,
      persistence: NSURLCredentialPersistence.ForSession)
    completionHandler( NSURLSessionAuthChallengeDisposition.UseCredential, cred )
  }

}

有什么想法吗？谢谢

如果您在没有＆＃34;私有＆＃34;的情况下注释掉该网址在其中并取消注释URL机智＆＃34;私人＆＃34;在它，它不起作用。如果您是通过网络浏览器（Chrome，Firefox，Safari等）＆＃34; https://bookapi.bignerdranch.com/private/courses.json＆＃34;输入凭证＆＃34; BigNerdRanch＆＃34;用户ID＆＃34; AchieveNerdvana＆＃34;对于密码，它返回预期的JSON

凭据请求无法在swift中运行
