我想通过node.js构建API,它在本地正常工作,但在云中失败.你能帮我找到这个bug吗？谢谢

app.get('/', function(req, res) {
  res.render('index.ejs');
});

app.get('/host', function(req, res) {
  var sessionId = app.get('sessionId'),
      // generate a fresh token for this client
      token = opentok.generateToken(sessionId, { role: 'moderator' });

  res.json('host.ejs', {
    apiKey: apiKey,
    sessionId: sessionId,
    token: token
  });

我设置了 daisyUI 但不知道如何按条件控制模态

我认为与 flowbite 或 bootstrap 类似 https://flowbite.com/docs/components/modal/

但是daisyUI还没有实现隐藏类，并且有

库中的模态开放方法

https://daisyui.com/components/modal/

<link href="https://cdn.jsdelivr.net/npm/daisyui@2.13.6/dist/full.css" rel="stylesheet" type="text/css" />
<script src="https://cdn.tailwindcss.com"></script>

<!-- The button to open modal -->
<label for="my-modal-4" class="btn modal-button">open modal</label>

<!-- Put this part before </body> tag -->
<input type="checkbox" id="my-modal-4" class="modal-toggle">
<label for="my-modal-4" class="modal cursor-pointer">
  <label class="modal-box relative" for="">
    <h3 class="text-lg font-bold">Congratulations random Interner user!</h3>
    <p class="py-4">You've been selected for a chance to get one year of subscription to use Wikipedia for free!</p>
  </label>
</label>

那么我们如何配置当前可见的模态视图呢？

多谢

我使用ActionBarActivity意图一个新的Activity但我不能在Activity中调用ActionBar方法

//        requestWindowFeature(Window.FEATURE_ACTION_BAR);
//        getActionBar().setTitle("123");
        ActionBar actionBar =getActionBar();
//
        actionBar.setDisplayHomeAsUpEnabled(true);

将得到null
