为改造创建 pojo 类和回调

Question

任何人都可以帮助如何使用 Retrofit 的回调为下面的 json 格式创建一个 pojo 类。

我试过http://www.jsonschema2pojo.org/，但我认为它的格式不太好

谢谢。

[
  {
   "trends": [
      {
        "tweet_volume": 3200,
        "events": null,
        "name": "#GanaPuntosSi",
        "promoted_content": null,
        "query": "%23GanaPuntosSi",
        "url": "http://twitter.com/search/?q=%23GanaPuntosSi"
      },
      {
        "tweet_volume": 4200,
        "events": null,
        "name": "#WordsThatDescribeMe",
        "promoted_content": null,
        "query": "%23WordsThatDescribeMe",
        "url": "http://twitter.com/search/?q=%23WordsThatDescribeMe"
     },
      {
        "tweet_volume": 1200,
        "events": null,
        "name": "#10PersonasQueExtra\u00f1oMucho",
        "promoted_content": null,
        "query": "%2310PersonasQueExtra%C3%B1oMucho",
        "url": "http://twitter.com/search/?
      }
   }
]

Answer 1

您只是在代码中忘记了]。

Answer 2

我对 Json 很陌生，我对它了解不多，但认为它是类似于 python 元组或 java 映射、python 字典的“键”：“值”对类型语言符号......（和很快）。据我所知，您的序列化程序有很多错误，因此请提供更多详细信息，以便更多合格人员可以通过帮助您修复它来帮助您，从而为您生成有效的 JSOn。

话虽如此，我一直在摆弄 JSON，直到它开始工作并生成一个 pojo。您可以将其粘贴到 jsonschema2pojo 并下载您的课程。希望这会有所帮助:)（PS。选择 Json 而不是 JsonSchema 单选按钮）

[
  {
    "tweet_volume": 3200,
    "events": null,
    "name": "#GanaPuntosSi",
    "promoted_content": null,
    "query": "%23GanaPuntosSi",
    "url": "http://twitter.com/search/?q=%23GanaPuntosSi"
  },
  {
    "tweet_volume": 4200,
    "events": null,
    "name": "#WordsThatDescribeMe",
    "promoted_content": null,
    "query": "%23WordsThatDescribeMe",
    "url": "http://twitter.com/search/?q=%23WordsThatDescribeMe"
 },
  {
    "tweet_volume": 1200,
    "events": null,
    "name": "#10PersonasQueExtra\u00f1oMucho",
    "promoted_content": null,
    "query": "%2310PersonasQueExtra%C3%B1oMucho",
    "url": "http://twitter.com/search/?"
  }
