php - WP_JSON 为移动应用准备数据，格式错误

Question

我正在尝试使用 wp-json rest api 从我的网站导出数据。应用程序应该以精确的格式读取这些数据，但我找不到提供正确结构的方法。

所需格式

事件应该按group类别分组，每个事件都应该有一个time参数，sessions我将存储该事件。这是应该的样子：

{
  "schedule": [
    {
      "date": "2047-05-17",
      "groups": [
        {
          "time": "26 July 2020",
          "sessions": [
            {
              "name": "Getting Started with Ionic",
              "location": "Hall 2",
              "description": "Mobile devices and browsers are now advanced enough that developers can build native-quality mobile apps using open web technologies like HTML5, Javascript, and CSS. In this talk, we’ll provide background on why and how we created Ionic, the design decisions made as we integrated Ionic with Angular, and the performance considerations for mobile platforms that our team had to overcome. We’ll also review new and upcoming Ionic features, and talk about the hidden powers and benefits of combining mobile app development and Angular.",
              "speakerNames": [
                "Ted Turtle"
              ],
              "timeStart": "9:30 am",

              ],
              "id": "3",
              "pic": "chicago.jpg"
            },
            
          ]

}

实际情况

sessions应该被包裹进groups，在当时，这些是不同的元素schedule。

{
   "schedule":[
      {
         "date":"2020-08-28",
         "groups":[
            {
               "time":"28 Aug 2020",
               "sessions":[
                  {
                     "name":"Getting Started with Ionic",
                     "location":"Hall 2",
                     "description":"Mobile devices and browsers are now advanced enough that developers can build native-quality mobile apps using open web technologies like HTML5, Javascript, and CSS.
