Question

我可以使用以下功能与服务器建立HTTP连接。

func isHostConnected(jsonString:NSDictionary, var retryCounter: Int) -> NSDictionary
{

    let request = NSMutableURLRequest(URL: NSURL(string: "http://***.*.*.**:****/")!)

    do {
        request.HTTPBody = try NSJSONSerialization.dataWithJSONObject(jsonString, options: [])
    } catch {
        //error = error1
        request.HTTPBody = nil
    }
    request.timeoutInterval = 45.0 //(number as! NSTimeInterval)
    request.HTTPMethod = "POST"
    request.setValue("application/json", forHTTPHeaderField: "Content-Type")
    request.setValue("gzip", forHTTPHeaderField: "Accept-encoding")

    var JSONdata: AnyObject = ["" : ""] as Dictionary<String, String>
    //print(JSONdata)

    if retryCounter == 0 {
        JSONdata = ["0" : "0"] as Dictionary<String, String>
        return (JSONdata) as! NSDictionary
    }
    retryCounter--

    let session = NSURLSession(configuration: NSURLSessionConfiguration.defaultSessionConfiguration())
    var responseCode = -1

    let group = dispatch_group_create()
    dispatch_group_enter(group)

    print("session.dataTaskWithRequest")
    delayTimer(1.0){

        session.dataTaskWithRequest(request, completionHandler: {(data, response, error) in
            if let httpResponse = response as? NSHTTPURLResponse {
                responseCode = httpResponse.statusCode
                let JSONresdata: AnyObject = (try! NSJSONSerialization.JSONObjectWithData(data!, options: .MutableContainers))
                JSONdata = JSONresdata as! NSDictionary
            }
            dispatch_group_leave(group)
        }).resume()
    }

    dispatch_group_wait(group, DISPATCH_TIME_FOREVER)
    print("responseCode == 200: \(responseCode)")
    if responseCode != 200 {
        print("retryCounter: \(retryCounter)")
        self.isHostConnected(jsonString,retryCounter: retryCounter)
    }
    return (JSONdata) as! NSDictionary
}

现在我们要在同一个功能中建立 HTTPS 连接，我有一个自签名证书。我想知道实现公钥是否需要在编写代码时使用自签名证书执行哪些步骤。

我在互联网上搜索但我没有在NSURLSession和swift 2中找到一个单独的例子或代码。请帮助我。

以下代码可能会有所帮助：link

 import UIKit
 import Foundation
 class ViewController: UIViewController, NSURLSessionDelegate {

     override func viewDidLoad() {
          super.viewDidLoad()
         httpGet(NSMutableURLRequest(URL: NSURL(string: "https://example.com")!))
     }

    func httpGet(request: NSMutableURLRequest!) {


        let session = NSURLSession(configuration: NSURLSessionConfiguration.defaultSessionConfiguration())
        session.dataTaskWithRequest(request, completionHandler: {(data, response, error) in


       }).resume()
   }


  func URLSession(session: NSURLSession, didReceiveChallenge challenge: NSURLAuthenticationChallenge, completionHandler: (NSURLSessionAuthChallengeDisposition, NSURLCredential?) -> Void) {
   completionHandler(NSURLSessionAuthChallengeDisposition.UseCredential, NSURLCredential(forTrust: challenge.protectionSpace.serverTrust!))
  }

}
