需要降噪的字段

print((denoiseJsonKey))

降噪之后两文件对比

print(ddiff2)

非降噪 两文件对比

ddiff3 = DeepDiff(t1, t2, view="tree", ignore_string_case=True)

按照降噪字段去除两文件的降噪值

"""
DeepDiff grep 、DeepSearch可以根据正则表达式来搜索和提取差异。它使用正则表达式来匹配输入对象中的路径和值，并在找到匹配的路径时返回相应的差异。

extract：Get the item from obj based on path.

exclude_types是DeepDiff中的一个选项，用于指定要排除比较的数据类型:exclude_types={str,int}
ignore_order=True: 可以设置忽略指定情况的顺序【1，3，2，4】 【1，2，3，4】 忽略后这俩 就是没有区别了
ignore_string_type_changes=True ： 忽略字符串类型的差异
ignore_numeric_type_changes=True：忽略数字类型的差异
ignore_string_case=True：忽略字母大小写的差异
verbose_level=2 : 对比差异的大小 一般为2 就可以
