这个场景理解起来可能不太容易，首先这是一个service嵌套场景，子service的请求会先于父service执行，因此这里涉及到父service请求回来的数据更新数据域后，能够让子service感知到，在amis中是通过trackExpression这个属性来控制的。详细可以看这个说明 https://aisuda.bce.baidu.com/amis/zh-CN/docs/types/api#%E8%B7%9F%E8%B8%AA%E6%95%B0%E6%8D%AE%E8%87%AA%E5%8A%A8%E5%88%B7%E6%96%B0

你可以修改代码如下，及告诉子service跟踪date变量的变化（"trackExpression": "${date}"）：

{
  "type": "page",
  "data": {
    "showtype": 0
  },
  "body": [
    {
      "type": "service",
      "api": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/mock2/page/initData",
      "body": [
        {
          "type": "panel",
          "title": "$title",
          "body": [
            {
              "type": "tpl",
              "tpl": "现在是：${date}",
              "inline": false,
              "id": "u:202f63e9ef7d"
            }
          ],
          "id": "u:99310706e1e9"
        },
        {

          },
          "body": [
