fastJSON 怎么快速获取某个键值

[ianyours]

{"result":{"code":1,"msg":"success","url":"","data":"0","date":"1530007139"},"data":{"token":"iamtoken","life":1530005620,"expires":7200}}

如以上的 String 怎么获取 比如token的值

[ZhuiZuoZheJian]

JSONObject.parseObject("").getJSONObject("data").getString("token");

第一个空的双引号字符串parseObject里面的参数填写你的字符串

[Mr.Java.]

public class Test {
public static void main(String[] args) {

String param = "{\"result\":{\"code\":1,\"msg\":\"success\",\"url\":\"\",\"data\":\"0\",\"date\":\"1530007139\"},\"data\":{\"token\":\"iamtoken\",\"life\":1530005620,\"expires\":7200}}";

JSONObject jsonObject = JSON.parseObject(param);


JSONObject jsonObject1 = JSONObject.parseObject(jsonObject.get("data").toString());

System.out.println(jsonObject1.get("token"));

}
}
