当我将JSON对象转换为字符串时，“ nameValuePairs”加到我的响应中

Question

响应是一个JSON对象，但是当我将其转换为字符串时，每行都会看到nameValuePairs。

我的JsonObject答复是：

{
  "type": "success",
  "value": [
    {
      "id": 1,
      "joke": "Chuck Norris uses ribbed condoms inside out, so he gets the pleasure.",
      "categories": [
        "explicit"
      ]
    },
    {
      "id": 2,
      "joke": "MacGyver can build an airplane out of gum and paper clips. Chuck Norris can kill him and take it.",
      "categories": [

      ]
    },
    {
      "id": 3,
      "joke": "Chuck Norris doesn't read books. He stares them down until he gets the information he wants.",
      "categories": [

      ]
    }
  ]
}

现在，当我进行转换时，它会在每个级别上添加nameValuePairs。
