我想为特定用户添加S3权限.AWS控制台正在向我询问用户的Canonical ID.我使用AWS CLI命令aws iam list-users检索用户列表,但没有"Canonical ID"字段,并且无法识别"User ID",这给我一个"Invalid ID"消息.我也尝试过使用ARN而且没用.
我正在尝试在gnome的通知面板上放置一个Java SystemTray图标(我正在使用OpenSuse 13.2,它使用gnome 3.14).
它不起作用,虽然SystemTray.isSupported()返回"true".我没有在屏幕上看到任何图标.我期待它出现在OpenSuse的通知区旁边.
这是主要的代码:
public static void main(String[] args) {
//checking for support
if (!SystemTray.isSupported()) {
System.out.println("System tray is not supported !!! ");
return;
}
SystemTray systemTray = SystemTray.getSystemTray();
Image image = Toolkit.getDefaultToolkit().getImage("icon.ico");
//popupmenu
PopupMenu trayPopupMenu = new PopupMenu();
//1t menuitem for popupmenu
MenuItem action = new MenuItem("Action");
action.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
JOptionPane.showMessageDialog(null, "Action Clicked");
}
});
trayPopupMenu.add(action);
//2nd menuitem of popupmenu
MenuItem close = new MenuItem("Close");
close.addActionListener(new ActionListener() {
@Override

Main.vue404.vue
如果用户进入正常页面,Main.vue则应使用该模板,每个页面都有嵌套路由。如果用户输入不存在的页面,404.vue则应使用有错误的模板。我尝试了以下操作,但它总是显示 404 错误,除了localhost:8080/(根路径访问):路由器.js:
