Google Calendar我的目标是通过WebEnginein自动登录JavaFX并在WebView. 但我似乎无法将字符串值插入密码字段，即使它与用户名字段完美配合。
我试过用 Java 创建脚本并用Element e = webEngine.getDocument().getElementById(password)插入值e.setAttribute("value","mypassword")，但这也不起作用。它没有提供任何堆栈跟踪，这意味着该元素存在，但我无法以某种方式插入该值。
System.setProperty("sun.net.http.allowRestrictedHeaders", "true");
WebEngine webEngine = webView.getEngine();
webEngine.load("https://calendar.google.com");
webEngine.getLoadWorker().stateProperty().addListener(
new ChangeListener<State>() {
@Override
public void changed(ObservableValue ov, State oldState, State newState) {
if (newState == State.SUCCEEDED) {
webEngine.executeScript(
"function login(user){"
+ " var usernameField = document.getElementById(\"identifierId\");"
+ " usernameField.value = user;"
+ " var sButton = document.getElementById(\"identifierNext\");"
+ " sButton.click();"
+ "}"
+ "login('myusername');"
);
}
}
});
Thread t = new Thread(() -> {
try {
Thread.sleep(5000);
} catch (InterruptedException e) {
e.printStackTrace();
}
Platform.runLater( () -> {
webEngine.executeScript(
"function login(pass){"
+ " var passwordField = document.getElementById(\"password\");"
+ " passwordField.value = pass;"
+ " var sButton = document.getElementById(\"passwordNext\");"
+ " sButton.click();"
+ "}"
+ "login('mypassword');"
);
});
});
t.start();
结果应该是，侦听器等待页面加载，然后填写用户名并单击下一步。然后线程开始但等待 5 秒以确保单击下一个，然后它应该填写密码凭据但没有。
