swift - 错误域=NSURLErrorDomain 代码=-1004

Question

我是初学者，在手机上部署我的应用程序时遇到问题。该应用程序在模拟器上运行良好，但当我在手机上运行并尝试在手机上发送注册表时，出现以下错误

FAILURE: Error Domain=NSURLErrorDomain Code=-1004 "Could not connect to the server." UserInfo={NSUnderlyingError=0x174244da0 {Error Domain=kCFErrorDomainCFNetwork Code=-1004 "(null)" UserInfo={_kCFStreamErrorCodeKey=61, _kCFStreamErrorDomainKey=1}}, NSErrorFailingURLStringKey=http://localhost/Syafiqah_153046u/register.php, NSErrorFailingURLKey=http://localhost/Syafiqah_153046u/register.php, _kCFStreamErrorDomainKey=1, _kCFStreamErrorCodeKey=61, NSLocalizedDescription=Could not connect to the server.}

下面是我的源代码

class ViewController: UIViewController {
    @IBOutlet weak var username: UITextField!
    @IBOutlet weak var password: UITextField!
    @IBOutlet weak var email: UITextField!
    @IBOutlet weak var fullname: UITextField!
    @IBOutlet weak var phone: UITextField!
    @IBOutlet weak var labelMessage: UILabel!

    @IBAction func Register(_ sender: UIButton)
    {
        let URL_USER_REGISTER = "http://localhost/FYP/register.php"

        let parameters: Parameters=[

            "username":username.text!,

            "password":password.text!,

            "email":email.text!,

            "fullname":fullname.text!,

            "phone":phone.text!

        ]

        //Sending http post request

        Alamofire.request(URL_USER_REGISTER, method: .post, parameters: parameters).responseJSON

            {
                response in

                //printing response

                print(response)



                //getting the json value from the server

                if let result = response.result.value

                {

                    //converting it as NSDictionary

                    let jsonData = result as! NSDictionary

                    //displaying the message in label

                    self.labelMessage.text = jsonData.value(forKey: "message") as! String?

                }
        }
    }

    override func viewDidLoad()
    {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }
   }

非常感谢您的帮助。谢谢你的时间

从 iPhone 访问本地主机将简单地进行环回/尝试连接到自身(如果它支持的话？)。

您需要做的是找到台式机的 IP(例如，如果是 Windows，请转到命令提示符并键入 ipconfig 或转到网络和共享中心并查找连接状态。
