java – 如何从Json中提取值

我从服务器得到一个响应字符串,如下所示

{"name":"Json","detail":{"first_name":"Json","last_name":"Scott","age":"23"},"status":"success"}

我想得到名字的价值.我怎样才能做到这一点？提前致谢.

解决方法

看这个代码我在应用程序中使用了什么

String data="{'foo':'bar','coolness':2.0,'altitude':39000,'pilot':{'firstName':'Buzz','lastName':'Aldrin'},'mission':'apollo 11'}";

我这样检索

JSONObject json = (JSONObject) JSONSerializer.toJSON(data);        
    double coolness = json.getDouble( "coolness" );
    int altitude = json.getInt( "altitude" );
    JSONObject pilot = json.getJSONObject("pilot");
    String firstName = pilot.getString("firstName");
    String lastName = pilot.getString("lastName");

    System.out.println( "Coolness: " + coolness );
    System.out.println( "Altitude: " + altitude );
    System.out.println( "Pilot: " + lastName );
