比较两个Json对象的解决方法可以使用以下代码示例：

1. 使用JSON库解析Json对象，并逐个比较每个键值对：

import json

def compare_json(json1, json2):
    # 解析Json对象
    obj1 = json.loads(json1)
    obj2 = json.loads(json2)

    # 比较每个键值对
    for key in obj1:
        if key not in obj2:
            return False
        if obj1[key] != obj2[key]:
            return False

    # 检查obj2是否有多余的键
    for key in obj2:
        if key not in obj1:
            return False

    return True

# 测试代码
json1 = '{"name": "John", "age": 30, "city": "New York"}'
json2 = '{"name": "John", "age": 30, "city": "London"}'
print(compare_json(json1, json2))  # 输出False

json3 = '{"name": "John", "age": 30, "city": "New York"}'
json4 = '{"name": "John", "age": 30, "city": "New York"}'
print(compare_json(json3, json4))  # 输出True

2. 使用深度比较库，如DeepDiff：

from deepdiff import DeepDiff

def compare_json(json1, json2):
    diff = DeepDiff(json1, json2)
    return not diff

# 测试代码
json1 = {"name": "John", "age": 30, "city": "New York"}
json2 = {"name": "John", "age": 30, "city": "London"}
print(compare_json(json1, json2))  # 输出False

json3 = {"name": "John", "age": 30, "city": "New York"}
json4 = {"name": "John", "age": 30, "city": "New York"}
print(compare_json(json3, json4))  # 输出True

以上是两种比较Json对象的解决方法，你可以根据自己的需求选择其中一种。
