我需要创建一个对象,它保存像[[{IMEI = 49015420323751}],[{PIN = 538000001}]]这样的值,以便将其转换为JSON.

现在我正在做的是

        ArrayList<ArrayList<HashMap<String,String>>> Request_Identifiers = new ArrayList<ArrayList<HashMap<String,String>>>();
        ArrayList<HashMap<String,String>> list1 = new ArrayList<HashMap<String,String>>();
        HashMap<String,String> map1 = new HashMap<String,String>();
        map1.put("IMEI","49015420323751");
        list1.add(map1);
        ArrayList<HashMap<String,String>> list2 = new ArrayList<HashMap<String,String>>();
        HashMap<String,String> map2 = new HashMap<String,String>();
        map2.put("PIN","538000001");
        list2.add(map2);

        Request_Identifiers.add(list1);    
        Request_Identifiers.add(list2);

但我现在需要在构造函数中执行此操作(就像我可以初始化字符串数组new String [] {"blocked","suspended","classmask"})或为此编写setter方法.怎么做 ？我真的很困惑.如果有人可以帮助我,我会很高兴.

提前致谢.

我需要在java中创建一个JSON对象,以便在java中传递请求

        {
            "attributes": ["blocked", "suspended"],
            "authPolicy":  ["device_valid"],
            "identity":  "first_id",
            "encoding": "default",
            "identifiers":
            [
                [
                    {"PIN": "234576"},
                    {"IMEI": "49015420323751"}
                ],
                [
                    {"PIN": "68000001"}
                ]
            ]
        }

所以我正在编写一个java类,并计划使用gson转换为json格式

        class RequestBody
        {
            String[] Request_Attributes;
            String[] Request_Policies;
            String Request_Identity;
            String …

我试图创建一个注册表但遇到此错误:

TypeError: 'Required' object is not iterable 

我的路线页是

from cafe_klatch import app
from flask import render_template,request,flash

@app.route('/')

def index():
