我正在尝试执行以下脚本:

import Foundation

class TestURLSession{

var session: NSURLSession!

func run(){
    session = NSURLSession.sharedSession()

    let url = NSURL(string: "http://www.veenex.de/tmp/json")
    let request = NSMutableURLRequest(URL: url!)
    request.setValue("application/json; charset=utf-8", forHTTPHeaderField: "Content-Type")
    request.HTTPMethod = "GET"

    let getDataTask = session.dataTaskWithRequest(request, completionHandler: {(data, response, error) in

        // HTTP Response contains an error
        if let httpResponse = response as? NSHTTPURLResponse {
            if httpResponse.statusCode != 200 {
                print("response was not 200: \(response)")
                return
            }
        }

        // Error submitting Request
        if error != nil {
            print("error submitting request: \(error)")
            return …
