不支持的URL swift ios发送Http请求

Question

我试图在swift中发送http请求。 我得到了一个方法（sendHttpRequest），它将dictionary<String,AnyObject>作为参数，并尝试使用php中的一个小服务器向localhost发送请求。当我点击调用此功能的按钮时会发生错误

  

＆＃34;可选（错误域= NSURLErrorDomain代码= -1002＆＃34;不支持的URL＆＃34; UserInfo = {NSErrorFailingURLStringKey = 46.101.145.122 / salvobertoncini.com / servo.php，NSErrorFailingURLKey = 46.101.145.122 / salvobertoncini .com / servo.php，NSLocalizedDescription =不支持的URL，NSUnderlyingError = 0x1763cef0 {错误域= kCFErrorDomainCFNetwork代码= -1002＆＃34;（null）＆＃34;}}）＆＃34;

Here is the code:

func sendHttpRequests(data : Dictionary<String, AnyObject>)
{

    let session = NSURLSession.sharedSession()
    do
    {
        let request = try NSJSONSerialization.dataWithJSONObject(data, options: .PrettyPrinted)
        let url = NSURL ( string : "127.0.0.1/Server/servo.php")
        let finalRequest = NSMutableURLRequest(URL: url!)

        finalRequest.HTTPMethod = "POST"
        finalRequest.HTTPBody = request

        let task = session.dataTaskWithRequest(finalRequest){ data,response,error in
            if error != nil
            {
                print("Error -> \(error)")
            }
            do
            {
                let result = try NSJSONSerialization.JSONObjectWithData(data!, options: []) as? [String:AnyObject]
                print("Result -> \(result)")
            }
            catch
            {
                print("Error -> \(error)")
            }
        }
        task.resume()
    }
    catch
    {
        print(error)
    }
}
