要比较两个具有相同名称但值不同的JSON文件，可以使用以下步骤来解决：

1. 读取两个JSON文件并将它们解析为Python对象。
2. 使用递归函数来遍历JSON对象的每个键和值。
3. 比较每个键的值，如果它们不相等，则记录下来。
4. 返回比较结果。

下面是一个示例代码，用于比较两个JSON文件的函数：

import json

def compare_json(file1, file2):
    with open(file1, 'r') as f1, open(file2, 'r') as f2:
        json1 = json.load(f1)
        json2 = json.load(f2)
    
    differences = {}

    def compare_objects(obj1, obj2, path=''):
        if isinstance(obj1, dict) and isinstance(obj2, dict):
            for key in obj1:
                if key in obj2:
                    compare_objects(obj1[key], obj2[key], f'{path}.{key}')
                else:
                    differences[f'{path}.{key}'] = (obj1[key], None)
            for key in obj2:
                if key not in obj1:
                    differences[f'{path}.{key}'] = (None, obj2[key])
        elif isinstance(obj1, list) and isinstance(obj2, list):
            for i in range(min(len(obj1), len(obj2))):
                compare_objects(obj1[i], obj2[i], f'{path}[{i}]')
            if len(obj1) > len(obj2):
                for i in range(len(obj2), len(obj1)):
                    differences[f'{path}[{i}]'] = (obj1[i], None)
            elif len(obj1) < len(obj2):
                for i in range(len(obj1), len(obj2)):
                    differences[f'{path}[{i}]'] = (None, obj2[i])
        else:
            if obj1 != obj2:
                differences[path] = (obj1, obj2)

    compare_objects(json1, json2)

    return differences

# 用法示例
differences = compare_json('file1.json', 'file2.json')
for key, (value1, value2) in differences.items():
    print(f'{key}: {value1} != {value2}')

请注意，此代码假设JSON文件的格式正确，并且它们没有嵌套太深以致于超出Python递归深度限制。如果JSON文件非常大或嵌套层级很深，可能需要对代码进行优化。
