如何提取含子数组的JSON样本数据并分配至对应字段？

Here's a complete, organized breakdown of all fields pulled from your sample JSON, mapped to their corresponding categories:

Core Device Identifier #

• Full IMEI: 35XXXXXXXXXXXXX
• IMEI Components:
  • TAC (Type Allocation Code): 35XXXX
  • FAC (Final Assembly Code): XX
  • CD (Check Digit): X
  • SNR (Serial Number): XXXXXX

Basic Device Metadata #

• Brand: NOKIA

Detailed Hardware Specifications #

• Weight: 130.0 grams
• Battery:
  • Type: Li-Ion
  • Capacity: 850 mAh
• QWERTY Keyboard Enabled: False
• Release Date: 2002 September (derived from the year array: ["2002", "09"])
• UMTS Talk Time: 0.0 hours
• Standby Time: 200.0 hours
• Touch Screen Enabled: False
• Physical Dimensions:
  • Width: 57.0 mm
  • Thickness: 26.0 mm
  • Height: 130.0 mm
• Wi-Fi Hotspot Supported: False
• CPU Clock Speed: 104 MHz (truncated value from sample data)

If you need to automate this extraction programmatically, here's a quick Python example using the built-in json module:

import json

# Sample JSON input (formatted for readability)
sample_data = '''{
  "imei": "35XXXXXXXXXXXXX",
  "imei_parts": { "fac": "XX", "cd": "X", "snr": "XXXXXX", "tac": "35XXXX" },
  "brand": "NOKIA",
  "info": {
    "weight": 130.0,
    "battery": [ "Li-Ion", 850 ],
    "qwerty": false,
    "year": [ "2002", "09" ],
    "talk_time_umts": 0.0,
    "stand_by": 200.0,
    "touch_scr": false,
    "size": { "width": 57.0, "thickness": 26.0, "height": 130.0 },
    "wifi_hotspot": false,
    "cpu_clock": 104
  }
}'''

# Parse the JSON string into a dictionary
parsed_data = json.loads(sample_data)

# Extract specific fields with direct key indexing
brand_name = parsed_data["brand"]
battery_type = parsed_data["info"]["battery"][0]
release_date = f"{parsed_data['info']['year'][0]}-{parsed_data['info']['year'][1]}"

# Output example
print(f"Device Brand: {brand_name}")
print(f"Release Date: {release_date}")
print(f"Battery Type: {battery_type}")

This code lets you access nested objects and array elements directly, making it easy to pull any field you need from the JSON structure.
