資料結構解析
- 將資料賦值給變數data_iphone後
變數名 | data_iphone |
資料類型 | 字典 |
key資料類型 | 字串 |
key | ‘data’ |
透過key取得value | data_iphone[‘data’] |
value資料類型 | 列表 |
value | [{‘creator’: {‘_id’: ‘5cecd40dd23e194ab0867aab’, ‘name’: ‘查理’, ‘username’: ‘cxt7777’}, ‘updater’: {‘_id’: ‘5cecd40dd23e194ab0867aab’, ‘name’: ‘查理’, ‘username’: ‘cxt7777’}, ‘deleter’: None, ‘createTime’: ‘2020-03-26T02:41:06.491Z’, ‘updateTime’: ‘2020-03-26T02:46:27.825Z’, ‘deleteTime’: None, ‘_widget_1557886562320’: ‘iPhone 11’, ‘_widget_1557886562335’: ‘5998’, ‘_widget_1557886562350’: ‘17’, ‘_id’: ‘5e7c164229e01a00063be284’, ‘appId’: ‘5e798363b587cc0006b40445’, ‘entryId’: ‘5cdb765b5a6ae613aeed0f84’}, {‘creator’: {‘_id’: ‘5cecd40dd23e194ab0867aab’, ‘name’: ‘查理’, ‘username’: ‘cxt7777’}, ‘updater’: {‘_id’: ‘5cecd40dd23e194ab0867aab’, ‘name’: ‘查理’, ‘username’: ‘cxt7777’}, ‘deleter’: None, ‘createTime’: ‘2020-03-26T02:47:02.037Z’, ‘updateTime’: ‘2020-03-26T02:47:02.037Z’, ‘deleteTime’: None, ‘_widget_1557886562320’: ‘iPhone X’, ‘_widget_1557886562335’: ‘4998’, ‘_widget_1557886562350’: ‘5’, ‘_id’: ‘5e7c17a650bccb0006441778’, ‘appId’: ‘5e798363b587cc0006b40445’, ‘entryId’: ‘5cdb765b5a6ae613aeed0f84’}, {‘creator’: {‘_id’: ‘5cecd40dd23e194ab0867aab’, ‘name’: ‘查理’, ‘username’: ‘cxt7777’}, ‘updater’: {‘_id’: ‘5cecd40dd23e194ab0867aab’, ‘name’: ‘查理’, ‘username’: ‘cxt7777’}, ‘deleter’: None, ‘createTime’: ‘2020-03-26T02:47:43.059Z’, ‘updateTime’: ‘2020-03-26T02:47:43.059Z’, ‘deleteTime’: None, ‘_widget_1557886562320’: ‘iPhone 8’, ‘_widget_1557886562335’: ‘3998’, ‘_widget_1557886562350’: ‘32’, ‘_id’: ‘5e7c17cfcd87510006cf8189’, ‘appId’: ‘5e798363b587cc0006b40445’, ‘entryId’: ‘5cdb765b5a6ae613aeed0f84’}] |
- data_iphone的value解析
變數名 | data_iphone[‘data’] |
資料類型 | 列表 |
取得列表中第一個資料 | data_iphone[‘data’][0] |
列表中第一個資料的值 | {‘creator’: {‘_id’: ‘5cecd40dd23e194ab0867aab’, ‘name’: ‘查理’, ‘username’: ‘cxt7777’}, ‘updater’: {‘_id’: ‘5cecd40dd23e194ab0867aab’, ‘name’: ‘查理’, ‘username’: ‘cxt7777’}, ‘deleter’: None, ‘createTime’: ‘2020-03-26T02:41:06.491Z’, ‘updateTime’: ‘2020-03-26T02:46:27.825Z’, ‘deleteTime’: None, ‘_widget_1557886562320’: ‘iPhone 11’, ‘_widget_1557886562335’: ‘5998’, ‘_widget_1557886562350’: ‘17’, ‘_id’: ‘5e7c164229e01a00063be284’, ‘appId’: ‘5e798363b587cc0006b40445’, ‘entryId’: ‘5cdb765b5a6ae613aeed0f84’} |
列表中第一個資料的資料類型 | 字典 |
列表中第一個資料中的key為’_widget_1557886562320’的value | data_iphone[‘data’][0][‘_widget_1557886562320’] |
