java - 如何解析这个 JSON 字符串

Question

我正在尝试将此字符串解析为 java，但我不断收到错误。

{"id":1,"jsonrpc":"2.0","result":{"limits":{"end":3,"start":0,"total":3},"sources":[{"file":"/media/storage/media/re Music/","label":"re Music"},{"file":"/media/storage/media/ra Music/","label":"ra Music"},{"file":"addons://sources/audio/","label":"Music Add-ons"}]}}

当我使用此代码时...

String temp = //json code returned from up above
JSONObject obj = new JSONObject(temp);
JSONArray array = obj.getJSONArray("sources");

我收到一条错误消息，显示 org.json.JSONObject Value...，然后显示 temp 中的内容。有什么帮助吗？

Answer 1

名为“sources”的数组有几层深。你需要向下遍历到json。

代码格式化程序可以帮助解决这些问题...

{
   "id":1,
   "jsonrpc":"2.0",
   "result":{
      "limits":{
         "end":3,
         "start":0,
         "total":3
      },
      "sources":[
         {
            "file":"/media/storage/media/re Music/",
            "label":"re Music"
         },
         {
            "file":"/media/storage/media/ra Music/",
            "label":"ra Music"
         },
         {
            "file":"addons://sources/audio/",
            "label":"Music Add-ons"
         }
      ]
   }
