2. UseuserDetailTag to get user IDNext, we can apply it in the templateuserDetailLabelled. To get the user ID, we need tonamethe parameter toIdAnd thenidspecify the parameter for the target user's ID.

   • Directly display the user ID:If you just want to display this ID on the page, you can write it like this:

     <div>指定用户的ID是：{% userDetail with name="Id" id="1" %}</div>
     

     This code will directly output the ID value of the user with ID 1.

   • Store the user ID in a variable and then display it:In more complex scenarios, you may need to store the obtained user ID in a temporary variable so that it can be reused in other places of the template or for some logical judgment. At this point, you can giveuserDetailLabel a specific one变量名称:

     {% userDetail specificUserId with name="Id" id="1" %}
     <div>获取到的用户ID是：{{ specificUserId }}</div>

      <div>欢迎回来，超级管理员！</div>
  {% else %}
      <div>欢迎访问我们的网站！</div>
  {% endif %}
