ios - 如何快速从 HTTP Get 获取状态码？

Question

我已尝试使用以下代码在 IOS Swift 中实现 HTTP Get。

NSURLConnection.sendAsynchronousRequest(request, queue: queue, completionHandler: {(response: NSURLResponse!, data: NSData!,error: NSError!) -> Void in

            var jsonResult: NSDictionary = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.MutableContainers, error: nil) as NSDictionary
            println("response = \(response)")
        })

它成功并显示以下响应:

response = <NSHTTPURLResponse: 0x155xxxxx> { URL: http://xxx.xx.xxx.xxx:38080/getid/user-wiced1 } 
{ status code: 200, headers {
    "Content-Length" = 111;
    "Content-Type" = "application/json; charset=UTF-8";
    Date = "Thu, 08 Jan 2015 07:31:21 GMT";
    Server = "spray-can/1.3.2-20140909";
} }

如何从 NSURLResponse 获取状态码？

NSURLResponse 没有状态码，但是 NSHTTPURLResponse 有。所以投它:

let httpResponse = response as NSHTTPURLResponse
httpResponse.statusCode
