下面的示例json是如何比较python中的两个json对象的。

sample_json1={
    {
       "globalControlId": 72,
       "value": 0,
       "controlId": 2
   },
   {
       "globalControlId": 77,
       "value": 3,
       "controlId": 7
   }
}

sample_json2={
    {
       "globalControlId": 72,
       "value": 0,
       "controlId": 2
   },
   {
       "globalControlId": 77,
       "value": 3,
       "controlId": 7
   }
}

这些不是有效的JSON/Python对象,因为数组/列表文本在[]而不是{}中:

更新:要比较字典列表(序列化的JSON对象数组),同时忽略列表项的顺序,需要对列表进行排序或转换为集合:

sample_json1=[{"globalControlId": 72, "value": 0, "controlId": 2},
              {"globalControlId": 77, "value": 3, "controlId": 7}]
sample_json2=[{"globalControlId": 77, "value": 3, "controlId": 7},
              {"globalControlId": 77, "value": 3, "controlId": 7}, # duplicity
              {"globalControlId": 72, "value": 0, "controlId": 2}]

# dictionaries are unhashable, let's convert to strings for sorting
sorted_1 = sorted([repr(x) for x in sample_json1])
sorted_2 = sorted([repr(x) for x in sample_json2])
print(sorted_1 == sorted_2)

# in case the dictionaries are all unique or you don't care about duplicities,
# sets should be faster than sorting
set_1 = set(repr(x) for x in sample_json1)
set_2 = set(repr(x) for x in sample_json2)
print(set_1 == set_2)

似乎通常的比较工作正常

import json
x = json.loads("""[
    {
       "globalControlId": 72,
       "value": 0,
       "controlId": 2
   },
   {
       "globalControlId": 77,
       "value": 3,
       "controlId": 7
   }
]""")

y = json.loads("""[{"value": 0, "globalControlId": 72,"controlId": 2}, {"globalControlId": 77, "value": 3, "controlId": 7 }]""")

x == y # result: True
