如何比较python中的2个json

Question

如何比较下面的python中的2个json对象是样本json。

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 
    } 
} 

Answer 1

这些都不是有效的JSON/Python对象，因为阵列/列表文字是内部的[]代替{}：

UPDATE：比较字典的列表（对象的串行化JSON阵列），而忽略列表项的顺序，列出需分类或转换为集：

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) 

Answer 2

看来，通常的比较正常工作

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
