如何使用python在JSON输出上显示所有匹配的字符串

import json
import re

def find_matching_strings(json_data, pattern):
    # 将JSON数据解析为Python对象
    data = json.loads(json_data)
    
    # 递归函数，用于在JSON对象中查找匹配的字符串
    def find_strings(obj, pattern):
        matches = []
        
        if isinstance(obj, str):
            # 使用正则表达式匹配字符串
            if re.search(pattern, obj):
                matches.append(obj)
        elif isinstance(obj, list):
            # 对于列表中的每个元素，递归调用find_strings函数
            for item in obj:
                matches.extend(find_strings(item, pattern))
        elif isinstance(obj, dict):
            # 对于字典中的每个值，递归调用find_strings函数
            for value in obj.values():
                matches.extend(find_strings(value, pattern))
        
        return matches
    
    # 调用递归函数，查找匹配的字符串
    matches = find_strings(data, pattern)
    
    # 返回所有匹配的字符串
    return matches

# 示例JSON数据
json_data = '''
{
  "name": "John Doe",
  "age": 30,
  "email": "johndoe@example.com",
  "address": {
    "street": "123 Main St",
    "city": "New York",
    "state": "NY"
  },
  "hobbies": ["reading", "traveling", "photography"],
  "projects": [
    {
      "name": "Project A",
      "description": "Lorem ipsum dolor sit amet"
    },
    {
      "name": "Project B",
      "description": "consectetur adipiscing elit"
    }
  ]
}
'''

# 指定要匹配的字符串模式
pattern = r"o"

# 调用函数查找匹配的字符串
matches = find_matching_strings(json_data, pattern)

# 打印所有匹配的字符串
for match in matches:
    print(match)
