使用带block回调方式的http请求启不是更好
let str = "http://www.baidu.com"
let url : NSURL =  NSURL(string: str)!
let request: NSURLRequest  = NSURLRequest(URL: url)
NSURLConnection.sendAsynchronousRequest(request, queue: NSOperationQueue.mainQueue()) {
          (response:NSURLResponse!, data:NSData!, error:NSError!) -> Void in
         ////////to do 
}
