JSON非常新。使用json-lib做这件事,并且一直拉着我的头发,试图从牛津字典API的这个JSON响应中获得“定义”。尝试了各种各样的事情。但从来没有比“结果”中的所有东西都更具体。想弄清楚为什么这是如此困难,否则就会诉诸正则表达式。从字典api解析JSON与Java
JSONObject obj = new JSONObject(stringBuilder.toString());
JSONArray arr = obj.getJSONArray("results");
String test = arr.getJSONObject(1).toString(); // Empty wtf?
String definition = obj.getString("definitions"); // empty also...
管理也进入“ID”,“语言”和“lexicalEntries”分开,但任何超出似乎并不想合作....这是一个正常的JSON响应?这很尴尬不?谢谢...

假设'字符串测试= arr.getJSONObject(0).toString();'有值inside.it最好使用像http://jsonviewer.stack.hu/工具来扩展json和分析。 –
