Fastjson parses multi-level JSON strings

Json character string ：

{
    "status":0,"result":{
    "location":{
    "lng":120.32521556751674,"lat":31.66420355596458},"precise":1,"confidence":75,"comprehension":57,"level":" Building number "}}

Code demonstration ：

JSONObject object = JSONObject.parseObject(response).getJSONObject("result").getJSONObject("location");
acc.setAccLng(object.getObject("lng", Double.class));
acc.setAccLat(object.getObject("lat", Double.class));

Happy songfanping kept laughing when he walked out of the photo studio , His happiness infected Li Lan , As they walked on , These two people have been laughing , Then Li baldheaded and Song Gang also giggled , Although the two children don't know why they laugh .
Remarried Li Lan was jubilant , Since her former husband drowned in the toilet , She survived seven years rather than death , Her hair has been in a doghouse for seven years , Now she has recovered her girl's pigtails , Also tied two red ropes at the end of the braid . Her face * It's like eating ginseng, and it suddenly turns ruddy , Her migraine headache suddenly disappeared , After hissing for seven years, her mouth began to hum a song . Her remarried husband is also red , As he walked in and out of the room, his feet thumped like drums , When he peed against the wall outside, it sounded like a storm .
This two married couple were like glue in their honeymoon , Once they seize the leisure, they will hide in the inner room , And the door is closed . Li baldhead and Song Gang can only fantasize in the outside room , The two children heard their mouths crackling when they were inside , Firmly believe that they hide inside and eat that bag of white rabbit milk candy . They not only eat during the day , In the evening, I can't stop eating . Before dark, they would force Li baldhead and Song Gang to go to bed , They shut themselves in the back room , Two mouths keep ringing . At this time, the neighbor's children were still running and shouting outside , Li baldhead and Song Gang can only go to bed , Songfanping and Li Lan also went to bed , But their mouths kept ringing in the room inside . Li baldheaded and Song Gang fell asleep with tears and drooling , When I woke up the next morning, my tears dried up , Saliva is still flowing .
