java - 解析JSON时，会发生奇怪的异常，因为:这不是JSON数组

我有一个JSON分析器。
这是来自服务器的JSON响应。

{
 "coord"  : {"lon":37.62,"lat":55.75},
 "weather":[{"id":803,"main":"Clouds","description":"test","icon":"04d"}],
 "base"   :"stations",
 "main"   :{"temp":12.76,"pressure":1007,"humidity":93,"tempmin":12,"tempmax":14},
 "visibility":6000,
 "wind"   :{"speed":4,"deg":300},
 "clouds" :{"all":75},
 "dt":1504881000,
 "sys"    :{"type":1,"id":7325,"message":0.0064,"country":"RU","sunrise":1504838942,"sunset":1504886617},
 "id"     :524901,
 "name"   :"City",
 "cod"    :200
 }

和java代码....

import org.json.JSONException;
import org.json.JSONObject;
import com.google.gson.*;

public static void main(String[] args) throws JSONException {
try {
JsonParser parser = new JsonParser();
JsonObject json = parser.parse("JSON responce here").getAsJsonObject();
JsonArray weather = json.get("weather").getAsJsonArray(); //no problem
int visibility = json.get("visibility").getAsInt();
int id = json.get("id").getAsInt();
int dt = json.get("dt").getAsInt();
String name = json.get("name").getAsString();
JsonArray clouds = json.get("clouds").getAsJsonArray(); //here is the problem
JsonArray main = json.get("main").getAsJsonArray(); //here is the problem
} catch (Exception e) {
        e.printStackTrace();
    }
}

问题是...当我编译时，我遇到了java.lang.IllegalStateException：这不是JSON数组。在JsonArray上== json.get（“ clouds”）。getAsJsonArray（）;和其他这样的行。

但是JsonArray weather = json.get（“ weather”）。getAsJsonArray（）;还行吧...

我不明白发生了什么...但是数组“天气”节点没有问题...完全。拜托，帮帮我...怎么了？

最佳答案

因为它是一个Json对象

JsonObject json = json.get("clouds").getAsJsonObject()

会的...

或者您可以按如下所示更改数据

{
 "coord"  : {"lon":37.62,"lat":55.75},
 "weather":{"id":803,"main":"Clouds","description":"test","icon":"04d"},
 "base"   :"stations",
 "main"   :{"temp":12.76,"pressure":1007,"humidity":93,"tempmin":12,"tempmax":14},
 "visibility":6000,
 "wind"   :{"speed":4,"deg":300},
 "clouds" :[{"all":75}],
 "dt":1504881000,
 "sys"    :{"type":1,"id":7325,"message":0.0064,"country":"RU","sunrise":1504838942,"sunset":1504886617},
 "id"     :524901,
 "name"   :"City",
 "cod"    :200
 }
