从文本文件替换JSON中的特定字段

import json
import re

# 读取文本文件和JSON文件
with open('text_file.txt', 'r') as f:
    text = f.read()

with open('json_file.json', 'r') as f:
    json_data = json.load(f)

# 提取需要替换的字段和值
pattern = r'Field: (\w+), Value: (\w+)'
matches = re.findall(pattern, text)

# 替换JSON中的字段
for field, value in matches:
    if field in json_data:
        json_data[field] = value

# 将更新后的JSON写入新文件
with open('updated_json_file.json', 'w') as f:
    json.dump(json_data, f)
