python - 值更新的 Json 写入问题

Question

所以，这段代码的目的是用用户提供的信息创建一个 json，但在最内层的循环中，值总是更新为用户最后插入的值。

import json


while True:
    keepGoing = True
    pay_obj = {
        'id': {0: {
        }
        }
    }
    pay_res = {
        "res": {
        }

    }
    pay_access = {
        'type': 'type',
        'acl': 'acl',
        'value': ''
    }
    obj_id = str(input('Insert obj ID: '))
    pay_obj[obj_id] = pay_obj['id']
    while keepGoing == True:
        print(pay_res)
        res_id = str(input('Insert resource ID: '))
        pay_res[res_id] = pay_res['res']
        type = str(input(f'Insert the data type for {res_id}: '))
        pay_access['type'] = type.upper()
        acl = str(input(f'Insert the access control level for {res_id}: '))
        pay_access['acl'] = acl.upper()
        pay_res[res_id] = pay_access
        cont = input('More resources?(y/n): ')
        if cont == 'n':
            pay_obj[obj_id]=pay_res
            del pay_obj['id']
            del pay_obj[obj_id]['res']
            pay_obj = json.dumps(pay_obj,indent=4)
            print(pay_obj)
            del pay_obj
            break

预期的输出应该是这样的 json

{
    "3303": {
        "3303": {
            "type": "STRING",
            "acl": "R",
            "value": ""
        },
        "3304": {
            "type": "STRING",
            "acl": "W",
            "value": ""
        }
    }
}

但使用正确的值，而不是资源中的最后一个值。

与 ncica 代码类似，我只是实现了一个额外的循环以在同一个 json 上引入更多对象:

import json

main={}

j=True
while j:
    obj_id = str(input('Insert obj ID: '))
    obj_temp={}
    keepGoing = True
    while keepGoing == True:
        res_id = raw_input('Insert resource ID for object ID %s: ' % obj_id)
        type = raw_input('Insert the data type for resource ID %s: '% res_id)
        val = raw_input('Insert the value for resource ID %s: ' % res_id)
        acl = raw_input('Insert the access control level for resource ID %s: ' % res_id)
        tmp_res = {"type": type, "acl": acl.upper(), "value": val.upper()}
        obj_temp[res_id]=tmp_res
        cont = raw_input('More resources?(y/n): ')
        if cont=='n':
            keepGoing=False
            cont1 = raw_input('More obj?(y/n): ')
            main[obj_id]=obj_temp
            if cont1=='n':
                j=False
print main

例子:

Insert obj ID: 1
Insert resource ID for object ID 1: 10
Insert the data type for resource ID 10: type10
Insert the value for resource ID 10: value10
Insert the access control level for resource ID 10: access10
More resources?(y/n): y
Insert resource ID for object ID 1: 20
Insert the data type for resource ID 20: type20
Insert the value for resource ID 20: value20
Insert the access control level for resource ID 20: access20
More resources?(y/n): n
More obj?(y/n): y
Insert obj ID: 2
Insert resource ID for object ID 2: 30
Insert the data type for resource ID 30: type30
Insert the value for resource ID 30: value30
Insert the access control level for resource ID 30: access30
More resources?(y/n): n
More obj?(y/n): n

{  
  '1':{  
    '10':{  
      'type':'type10',
      'value':'VALUE10',
      'acl':'ACCESS10'
    },
    '20':{  
      'type':'type20',
      'value':'VALUE20',
      'acl':'ACCESS20'
    }
  },
  '2':{  
    '30':{  
      'type':'type30',
      'value':'VALUE30',
      'acl':'ACCESS30'
    }
  }
}
