【Java】指定【微信】好友自動發送消息

Backgroud

原理很簡單：robot類模拟鍵盤輸入，快捷鍵打開微信，搜尋好友，把發送内容發送到粘貼闆實作。

另外一篇部落格介紹了通過python實作Python指定wx好友自動發送消息

public class T5 {

    public static void main(String[] args) throws InterruptedException {
        // 好友昵稱
//        String friendNickName = "檔案傳輸助手";
        String friendNickName = "不器";

        searchMyFriendAndSend(friendNickName);
    }

    private static void searchMyFriendAndSend(String friendNickName) throws InterruptedException {
        // 建立Robot對象
        Robot robot = getRobot();
        //打開微信 Ctrl+Alt+W
        assert robot != null;
        robot.keyPress(KeyEvent.VK_CONTROL);
        robot.keyPress(KeyEvent.VK_ALT);
        robot.keyPress(KeyEvent.VK_W);
        //釋放Ctrl按鍵，像Ctrl，倒退鍵，删除鍵這樣的功能性按鍵，在按下後一定要釋放
        robot.keyRelease(KeyEvent.VK_CONTROL);
        robot.keyRelease(KeyEvent.VK_ALT);

        // 該延遲不能少，否則無法搜尋
        robot.delay(1000);

        // Ctrl + F 搜尋指定好友
        robot.keyPress(KeyEvent.VK_CONTROL);
        robot.keyPress(KeyEvent.VK_F);
        robot.keyRelease(KeyEvent.VK_CONTROL);

        // 将好友昵稱發送到剪切闆
        Clipboard clip = Toolkit.getDefaultToolkit().getSystemClipboard();
        Transferable tText = new StringSelection(friendNickName);
        clip.setContents(tText, null);
        // 以下兩行按下了ctrl+v，完成粘貼功能
        robot.keyPress(KeyEvent.VK_CONTROL);

        // 發送消息
        sendMsg();
    }

    private static void sendMsg() throws InterruptedException {
        String[] mottoes = {
                "我隻愛你四天，春天夏天秋天冬天！",
                "我隻愛你三天，昨天,今天,明天！",
                "我隻愛你兩天，白天，黑天！",
                "我隻愛你一天，每一天！",
                "[玫瑰]愛你麼麼哒！",
                "[呲牙][壞笑]",
                "[奸笑]"
        };
        for (String motto : mottoes) {
            sendOneMsg(motto);
        }
        Thread.sleep(2000);

        sendOneMsg("[得意]就問你，膩不膩害！");
    }

    private static void sendOneMsg(String msg) {
        // 建立Robot對象
        Robot robot = getRobot();
        Clipboard clip = Toolkit.getDefaultToolkit().getSystemClipboard();
        // 将字元串複制到剪切闆
        Transferable tText = new StringSelection(msg);
        clip.setContents(tText, null);
        // 以下兩行按下了ctrl+v，完成粘貼功能
        robot.keyPress(KeyEvent.VK_CONTROL);
        robot.keyPress(KeyEvent.VK_V);
        robot.keyRelease(KeyEvent.VK_CONTROL);
        // 回車發送
        robot.keyPress(KeyEvent.VK_ENTER);
        robot.delay(1000);
    }

    private static Robot getRobot(){
        // 建立Robot對象
        Robot robot = null;
        try {
            robot = new Robot();
        } catch (AWTException e) {
            e.printStackTrace();
        }
        return robot;
    }

}
           

效果如下圖所示
