如何在 Python 中比较两个 Json 数组？

Question

我正在创建一个脚本，该脚本允许将两个 ssh 命令输出与远程 Netapp 进行比较，并且允许在当前值和 Netapp 机舱具有的最大空间值之间进行比较。我已经在两个字典（rv 和 rv 2）中收集了这些值，然后我将它们转换为 JSON 格式，以便能够根据传递给它的警告参数来比较它们（如果超过这个限制，它就会通知）。我想比较的值的示例： RV1：{'node1.storePool_Owner': ['160'], 'node1.storePool_Deleg': ['0'], 'node2.storePool_LockState': ['0']}RV2：{'node1.storePool_Owner': ['1024000'], 'node1.storePool_Deleg': ['1024000'], 'node2.storePool_LockState': ['1024000']}这个想法是将这些值中的每一个与它们的最大等效值进行比较。非常感谢你的帮助。应该如何比较的一个例子： 如果这个节点，具有那个值：node1.storePool_Owner': ['160']达到以下的 X%（警告 arg）：node1.storePool_Owner': ['1024000']然后它应该返回：WARNING: node1.storePool_Owner has exceeded the threshold (x%)

这将比较两个 json 文件/字典。我注意到这些值是字符串列表......这是故意的吗？

import json

def open_json(path):

    with open(path, 'r') as file:

        return json.load(file)

def check_thresholds(data, thresholds):

    for k, v in thresholds.items():

        # your logic/output here

        # k[0] and v[0] because your values are lists of strings... should they be just int of float?

        difference = int(data.get(k)[0]) - int(v[0])

        if difference >= 0:

            print(f'WARNING: {k} has exceeded the threshold by {difference}')

        else:

            print(f'OK: {k}')

def main():

    # load the data into dictionaries

    data = open_json('./rv.json')

    thresholds = open_json('./rv2.json')

    # if your data is a dictionary and not json files then use these

    # data = {'node1.storePool_Owner': ['160'], 'node1.storePool_Deleg': ['0'], 'node2.storePool_LockState': ['0']}

    # thresholds = {'node1.storePool_Owner': ['1024000'], 'node1.storePool_Deleg': ['1024000'], 'node2.storePool_LockState': ['1024000']}

    # run the checks

    check_thresholds(data, thresholds)

main()

输出（我修改了一些值以显示警告）：

WARNING: node1.storePool_Owner has exceeded the threshold by 1000

OK: node1.storePool_Deleg

OK: node2.storePool_LockState
