放心-如何验证同名的JSON响应字段

import json

def validate_json_response(json_response, field_path):
    data = json.loads(json_response)
    field_names = field_path.split('.')
    
    # 遍历字段路径
    current_data = data
    for field_name in field_names:
        if field_name in current_data:
            current_data = current_data[field_name]
        else:
            # 字段不存在，验证失败
            raise ValueError(f"Field '{field_name}' not found in JSON response.")
    
    # 验证字段值是否符合预期
    expected_value = "expected value"
    if current_data != expected_value:
        raise ValueError(f"Field '{field_path}' has unexpected value: {current_data}")
    
    # 验证通过
    print(f"Field '{field_path}' is valid.")

# 示例用法
json_response = '{"data": {"name": "John", "age": 30}}'
field_path = "data.name"
validate_json_response(json_response, field_path)
