我有套接字问题

import socket

serverName = "herk-PC"
serverPort = 12000

clientSocket = socket.socket(socket.AF_INET,socket.SOCK_DGRAM)

message = input('input lowercase sentence:')

clientSocket.sendto(message.encode('utf-8'),(serverName, serverPort))

modifiedMessage, serverAddress = clientSocket.recvfrom(2048)


print (modifiedMessage.decode('utf-8'))

clientSocket.close()

这段代码给我错误

Traceback (most recent call last):
  File "J:\Sistem Jaringan\Task I\client.py", line 12, in <module>
    modifiedMessage, serverAddress = clientSocket.recvfrom(2048)
ConnectionResetError: [WinError 10054] An existing connection was forcibly closed by the remote host

我的错误有什么解决办法吗？

我的 Laravel 有问题，我无法发布数据

一个错误说

InvalidArgumentException in Validator.php line 2593:
Validation rule unique requires at least 1 parameters.

这是我的代码

public function postUbah(Request $request, $id)

    $validator  = Validator::make($request->all(), [
            'username'  => 'required|unique:user|min:5',
            'name'      => 'required',
            'group'     => 'required'
        ]);
}

谢谢您的帮助。

这是我的模型

class User extends Model implements AuthenticatableContract, CanResetPasswordContract {

    use Authenticatable, CanResetPassword;


    protected $table = 'user';


    protected $fillable = ['username', 'password'];


    protected $hidden = ['password', 'remember_token'];

我想在这个弹出对话框中点击“确定”按钮

我试过：

driver.switchTo().alert().accept(); 

但它不起作用

我的代码有问题

nama=txtNama.getText().trim();
int nim =Integer.parseInt(txtNIM.getText());
alamat=txtAlamat.getText().trim();
int telp =Integer.parseInt(txtTelp.getText());

在代码整数

int nim =Integer.parseInt(txtNIM.getText());
int telp =Integer.parseInt(txtTelp.getText());

我只能输入10个数字，如果输入超过10个数字就会出错

线程“AWT-EventQueue-0”中的异常java.lang.NumberFormatException：对于输入字符串：“1111111111111”

感谢您的关注和帮助。
