此文产生的缘由：陪舍友玩Bilibili的1024活动

根据前两张图的提示写出了下面的代码

后面利用JSONObject提取JSON中的字段，当Status Code为200时，提取所需字段。参考了这篇文章。

<!--Bilibili API返回的JSON-->
{"code":"403","data":"","msg":""}

// JSONObject如何使用
import java.io.File;
import java.io.IOException;
 
import org.apache.commons.io.FileUtils;
import org.json.JSONArray;
import org.json.JSONObject;
 
public class JSONObjectSample {
 
    public static void main(String[] args) throws IOException {
        File file = new File("src/main/java/demo.json");
        String content = FileUtils.readFileToString(file);
        //对基本类型的解析
        JSONObject obj = new JSONObject(content);
        System.out.println("name：" + obj.getString("name"));
        System.out.println("sex：" + obj.getString("sex"));
        System.out.println("age" + obj.getInt("age"));
        System.out.println("is_student" + obj.getBoolean("is_student"));
        //对数组的解析
        JSONArray hobbies = obj.getJSONArray("hobbies");
        System.out.println("hobbies：");
        for (int i = 0; i < hobbies.length(); i++) {
            String s = (String) hobbies.get(i);
            System.out.println(s);
        }
    }
}

应该有用的代码
