我正在尝试阅读json网址
我的代码：
// Creating JSON Parser instance
JSONParser jParser = new JSONParser();
// getting JSON string from URL
JSONObject json = jParser.getJSONFromUrl(url);
如果我执行我的代码，我无法从URL获取字符串
这是我的LogCat错误：

有人可以帮忙吗？
答案 0 :(得分：2)
您从URL获取的值是JSONArray而不是JSONOBject。 （那是方括号的意思）。试试这个：
JSONArray json = jParser.getJSONFromUrl(url);
JSONObject firstObject = json.getJSONObject(0);
JSONObject secondObject = json.getJSONObject(1);
...etc
答案 1 :(得分：0)
那是因为JSONArray不是JSONObject的孩子。
JSONArray仅展开java.lang.Object。
JSONArray类的签名是：
public class org.json.JSONArray {
... class body ...
}
答案 2 :(得分：0)
线索在异常结束时：... of type org.json.JSONArray cannot be converted to JSONObject。给定网址的JSON是有效的JSON，但格式为JSONArray，而不是JSONObject。
尝试将该行更改为JSONArray json = jParser.getJSONFromUrl(url);，它应该有效。
