## Plugin-specific files:

抛出异常：

jsonArray=jsonObject.getJSONArray("server_response");

什么是正确的陈述？

我的代码：

org.json.JSONException: 
    Value[{"code":"login_true","name":"hhh","email":"hhh"}]
    of type org.json.JSONArray cannot be converted to JSONObject".

Answer 1

假设从服务器返回的JSON是：

[{"code":"login_true","name":"hhh","email":"hhh"}]

解析上述JSON：

try {
  JSONArray jsonArray = new JSONArray(json);
  JSONObject jsonObject = jsonArray.getJSONObject(0);
  String code = jsonObject.getString("code");
  String name = jsonObject.getString("name");
} catch (JSONException e) {
  e.printStackTrace();
}

JSONException：无法将值转换为JSONObject
