Question

我创建了一个登录窗口，其中包含两个用于用户名和密码的文本框，以及两个用于登录和取消的命令按钮。按下取消按钮后窗口关闭。登录凭据应作为参数传递给powershell脚本以登录网站..我无法链接PowerShell和java swing代码..

我的java swing代码是：

import static java.awt.GraphicsDevice.WindowTranslucency.PERPIXEL_TRANSLUCENT;
import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.BufferedReader;
import java.io.FileReader;
import java.io.InputStream;
import java.io.InputStreamReader;

public class Credential extends JFrame {
    /**
     * 
     */
    private static final long serialVersionUID = 1L;

    public Credential() {
        setUndecorated(true);
        setBackground(new Color(0, 0, 0, 0));
        setSize(new Dimension(400, 300));
        setLocationRelativeTo(null);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        JPanel panel = new JPanel() {

            /**
             * 
             */
            private static final long serialVersionUID = 1L;

            @Override
            protected void paintComponent(Graphics g) {
                super.paintComponent(g);
                if (g instanceof Graphics2D) {
                    final int R = 220;
                    final int G = 220;
                    final int B = 250;
                    Paint p = new GradientPaint(0.0f, 0.0f, new Color(R, G, B,
                            0), 0.0f, getHeight(), new Color(R, G, B, 255),
                            true);
                    Graphics2D g2d = (Graphics2D) g;
                    g2d.setPaint(p);
                    g2d.fillRect(0, 0, getWidth(), getHeight());
                    Font font = new Font("Serif", Font.PLAIN, 45);
                    g2d.setFont(font);
                    g2d.setColor(Color.lightGray);
                    g2d.drawString("Get Credential", 60, 80);
                }
            }

        };

        setContentPane(panel);
        setLayout(new FlowLayout());
        placeComponents(panel);

    }

    public static void placeComponents(JPanel panel) {

        panel.setLayout(null);

        JLabel userLabel = new JLabel("User");
        userLabel.setBounds(40, 100, 80, 25);
        panel.add(userLabel);

        JTextField userText = new JTextField(20);
        userText.setBounds(130, 100, 160, 25);
        userText.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
            }
        });

        panel.add(userText);

        JLabel passwordLabel = new JLabel("Password");
        passwordLabel.setBounds(40, 140, 80, 25);
        panel.add(passwordLabel);

        JPasswordField passwordText = new JPasswordField(20);
        passwordText.setBounds(130, 140, 160, 25);
        panel.add(passwordText);

        JButton loginButton = new JButton("login");
        loginButton.setBounds(100, 180, 80, 25);
        loginButton.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
            }
        });

        panel.add(loginButton);

        JButton cancelButton = new JButton("cancel");
        cancelButton.setBounds(220, 180, 80, 25);
        cancelButton.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                System.exit(0);
            }
        });
        panel.add(cancelButton);
    }

    public static void main(String[] args) {
        GraphicsEnvironment ge = GraphicsEnvironment
                .getLocalGraphicsEnvironment();
        GraphicsDevice gd = ge.getDefaultScreenDevice();
        boolean isPerPixelTranslucencySupported = gd
                .isWindowTranslucencySupported(PERPIXEL_TRANSLUCENT);
        if (!isPerPixelTranslucencySupported) {
            System.out.println("Per-pixel translucency is not supported");
            System.exit(0);
        }
        SwingUtilities.invokeLater(new Runnable() {
            @Override
            public void run() {
                Credential gtw = new Credential();

                gtw.setVisible(true);
            }
        });
    }
}

powershell脚本是这样的：

$url = "https://www.jabong.com/customer/account/login/"
$username = $cred.username
 $username = $username.Replace("\", "")
$password = $cred.GetNetworkCredential().password
$ie = New-Object -com internetexplorer.application; 
$ie.visible = $true; 
$ie.navigate($url); 
while ($ie.Busy -eq $true) 
{ 
    Start-Sleep 1; 

} 
$ie.Document.getElementById("LoginForm_email").value = $username
$ie.Document.getElementByID("LoginForm_password").value=$password
$ie.Document.getElementByID("qa-login-button").Click();

有几种方法可以解决这个问题。例如，您可以使用用户名和密码作为参数运行PowerShell脚本：

Process process = new ProcessBuilder(
                    "powershell.exe",
                    "-File", "C:\\path\\to\\your.ps1",
                    "-Username", userText.getText(),
                    "-Password", passwordText.getText()
                  ).start();

并制作脚本的$Username和$Password parameters：

[CmdletBinding()]
Param(
  [Parameter()][string]$Username,
  [Parameter()][string]$Password
)

$url = 'https://www.jabong.com/customer/account/login/'
$ie  = New-Object -COM internetexplorer.application
...

但这是不好的做法，因为密码会以明文形式出现在流程列表中。

更好的选择是将用户名和密码作为environment variables传递：

ProcessBuilder pb = new ProcessBuilder(
                      "powershell.exe",
                      "-File", "C:\\path\\to\\your.ps1"
                    );
Map<String, String> env = pb.environment();
env.put("USER", userText.getText());
env.put("PASS", passwordText.getText());
Process process = pb.start();

可以在脚本中访问，如下所示：

$username = $env:USER
$password = $env:PASS

或者你可以反过来从PowerShell脚本运行Java程序：

$username, $password = & java -jar '.\Credential.jar'

并将凭据写入Java程序中的stdout：

System.out.println(userText.getText());
System.out.println(passwordText.getText());

请注意，无论哪种方式，您都需要制作类的userText和passwordText个实例变量，并将placeComponents()更改为非静态方法。

话虽如此，如果Java / Swing不是硬性要求，使用Windows forms也可以提供一种构建自定义对话框的方法（允许您保持对话和脚本代码在同一个文件中）：

Add-Type -AssemblyName System.Windows.Forms
Add-Type -AssemblyName System.Drawing

function New-Button($label, $action, $width, $height, $top, $left) {
  $btn = New-Object System.Windows.Forms.Button
  $btn.Location = New-Object System.Drawing.Size($left, $top)
  $btn.Size = New-Object System.Drawing.Size($width, $height)
  $btn.Text = $label
  $btn.Add_Click($action)
  $btn
}

function New-Label($label, $width, $height, $top, $left) {
  $lbl = New-Object System.Windows.Forms.Label
  $lbl.Location = New-Object System.Drawing.Size($left, $top)
  $lbl.Size = New-Object System.Drawing.Size($width, $height)
  $lbl.Text = $label
  $lbl
}

function New-Input($width, $height, $top, $left, $mask=$false) {
  $input = New-Object System.Windows.Forms.TextBox
  $input.UseSystemPasswordChar = $mask
  $input.Location = New-Object System.Drawing.Size($left, $top)
  $input.Size = New-Object System.Drawing.Size($width, $height)
  $input
}

$form = New-Object System.Windows.Forms.Form
$form.Size = New-Object System.Drawing.Size(250, 160)

$form.Controls.Add((New-Label 'Username:' 60 20 20 10))
$user = New-Input 150 20 20 70
$form.Controls.Add($user)

$form.Controls.Add((New-Label 'Password:' 60 20 50 10))
$pass = New-Input 150 20 50 70 $true
$form.Controls.Add($pass)

$form.Controls.Add((New-Button 'OK' {$form.Close()} 70 23 85 70))
$form.Controls.Add((New-Button 'Cancel' {$user.Text=''; $pass.Text=''; $form.Close()} 70 23 85 150))

[void]$form.ShowDialog()

$username = $user.Text
$password = $pass.Text
