如何将String转换为JsonObject

I am using a HttpURLConnection to get Json from a web into a string.

我正在使用HttpURLConnection将Json从Web转换为字符串。

And i'm storing web string into BufferedReader and after that storing it in a new String.

我将Web字符串存储到BufferedReader中,之后将其存储在新的String中。

And string is here:-

字符串在这里: -

{"coord":{"lon":72.85,"lat":19.01},"weather":[{"id":801,"main":"Clouds","description":"few clouds","icon":"02d"}],"base":"stations","main":{"temp":302.131,"pressure":1024.24,"humidity":84,"temp_min":302.131,"temp_max":302.131,"sea_level":1024.75,"grnd_level":1024.24},"wind":{"speed":4.77,"deg":302.001},"clouds":{"all":12},"dt":1459677392,"sys":{"message":0.0102,"country":"IN","sunrise":1459645229,"sunset":1459689786},"id":1275339,"name":"Mumbai","cod":200}

How can i convert it into JsonObject.

我怎样才能将它转换为JsonObject。

I've also seen this answer (How to convert String to JsonObject) but it's not working.

我也看到了这个答案(如何将String转换为JsonObject),但它没有用。

Here is code:-

这是代码: -

    BufferedReader br= new BufferedReader(new InputStreamReader(conn.getInputStream()));

    String localoutput;
    while ((localoutput = br.readLine()) != null) 
    {
            output=localoutput+output;
    }
    conn.disconnect();
    }
    catch(Exception e)
    {
        System.out.println(e);  
    }

JsonReader jsonReader = Json.createReader(new StringReader(output));
JsonObject object = jsonReader.readObject();
jsonReader.close();

try {
    String cityname = object.getString("name");
    System.out.println(cityname);
} 
catch (Exception e)
{
    e.printStackTrace();
}

Here output is the String which I've mentioned it earlier. I'm not getting the Output Cityname in my console.

这里输出的是我之前提到过的字符串。我没有在控制台中获取输出城市名称。
