【问题描述】：
我正在使用 node.js 从网站获取数据。一旦我获得了想要插入到 mySQL 数据库中的数据。获取 url 给了我一个 json 信息转储。
格式化字符串后，我使用一个数组来存储我的数据。以下是我的输出示例：
['table_id: 0xFC (252) SCTE 35',
"section_syntax_indicator: '0'",
"private_indicator: '0'",
"reserved: '11'",
'section_length: 0x39 (57)',
'protocol_version: 0',
'encrypted_packet: 0 no part of this message is encrypted',
'encryption_algorithm: 0 No encryption',
'pts_adjustment: 0xFFFF7F18 (33000) > Time: 95443.4 sec > (hh:mm:ss.ms) 26:30:43.351',
'cw_index: 0x00 (0)',
'tier: 0x0FFF (4095)',
'splice_command_length: 0x0005 (5)',
'splice_command_type: 0x06 (6) time_signal [] time_signal: > Time: 19345 sec > (hh:mm:ss.ms) 05:22:24.972',
'time_specified_flag: 1 presence of the pts_time field',
'reserved: 0x3F (63)',
'pts_time: PTS: 1741047514 [0x67C646DA] > Time: 19345 sec > (hh:mm:ss.ms) 05:22:24.972',
'descriptor_loop_length: 35 [] Descriptors: [] segmentation_descriptor (0x02): Content Identification (0x01)',
'descriptor_tag: 0x02 (2)',
'descriptor_length: 0x21 (33)',
'identifier: 0x43554549 (CUEI)',
'segmentation_event_id: 0x00000001 (1)',
"segmentation_event_cancel_indicator: '0' a previously sent segmentation event, identified by segmentation_event_id, has NOT been cancelled",
'reserved: 0x7F (127)',
"program_segmentation_flag: '1' the message refers to a Program Segmentation Point and that the mode is the Program Segmentation Mode whereby all PIDs/components of the program are to be segmented",
"segmentation_duration_flag: '0' No presence of segmentation_duration field",
"delivery_not_restricted_flag: '1' the next five bits are reserved",
'reserved: 0x1F (31)',
'segmentation_upid_type: 0x01 (1) Deprecated: use type 0x0C; The segmentation_upid does not follow a standard naming scheme.',
'segmentation_upid_length: 0x12 (18)',
'segmentation_type_id: 0x01 (1) Content Identification',
'segment_num: 0x01 (1)',
'segments_expected: 0x01 (1)',
'CRC_32: 0x46D15AF3 CRC OK'
]
我想把这个数组的每个元素分成不同的类别。
例如："time_specified_flag: 1 presence of the pts_time field"
我希望这个元素分为 3 个不同的类别（参数、值、描述）。赞[time_specified_flag, 1, presence of the pts_time field]

这是我的代码 sn-p 来格式化这个数据块：
My code to format the JSON response
这是可以做到的吗？
【问题讨论】：
-
你能分享一个来自 URL 的 JSON 的小 sn-p 以及你用来将它格式化为这个结构的代码吗？
-
只要努力，一切皆有可能。您能否分享一些您尝试过的代码或您遇到的问题。
-
map函数可以轻松处理这个问题。此外，使用原始的json结构可能更容易。那看起来像什么？ -
@maazadeeb 我更新了帖子。
-
另外，@ToddSkelton JSON 看起来很痛苦。所以我需要格式化我只抓住重要的东西。
