我有这段代码来获取 X-Transmission-Session-Id 但现在我需要使用更新的标头重新发送请求。
function takeXTransmissionSessionId( ){
let urls = NSURL(string: "\(url)")
let task = NSURLSession.sharedSession().dataTaskWithURL(urls!) { (data, respornse, error) -> Void in
guard error == nil && data != nil else {
print("error=\(error!)")
let alertView = UIAlertController(title: "ERROR", message: "A server with the specified hostname could not be found.", preferredStyle: UIAlertControllerStyle.Alert)
let actionView = UIAlertAction(title: "OK", style: UIAlertActionStyle.Cancel, handler: nil)
alertView.addAction(actionView)
self.presentViewController(alertView, animated: true, completion: nil)
return
}
if let httpStatus = respornse as? NSHTTPURLResponse where httpStatus.statusCode != 200 {
let sesionID = httpStatus.allHeaderFields["X-Transmission-Session-Id"]
if sesionID == nil {
let alertView = UIAlertController(title: "ERROR", message: "The request has not been applied because it lacks valid authentication credentials for the target resource.", preferredStyle: UIAlertControllerStyle.Alert)
let actionView = UIAlertAction(title: "OK", style: UIAlertActionStyle.Cancel, handler: nil)
alertView.addAction(actionView)
self.presentViewController(alertView, animated: true, completion: nil)
}else{
//print("\(respornse!)")
//print("\(sesionID!)")
self.XTransmissionSessionId = "\(sesionID!)"
}
}
}
task.resume()
}
我的问题是我以不同的方式多次托盘，但我不知道我需要做什么。
谢谢！
