循环使用API JSON数据和计数状态‘

Question

我从rest和函数的请求库中获取数据：

def read_compressors():

    x = requests.get('http://10.200.200.223:5000/bacnet/read/multiple',json=my_rtu_read)
    print(x.status_code)
    return x.json()

其中x看起来如下：

{'status': 'read_success', 'data': {'cooling_stage_1': {'pv': 'active'}, 'cooling_stage_2': {'pv': 'active'}, 'cooling_stage_3': {'pv': 'inactive'}, 'cooling_stage_4': {'pv': 'inactive'}}}

我如何循环通过data和计数所有冷却阶段，即active？在data中可能有很多阶段，但在本例中只有4，cooling_stage_1通过cooling_stage_4。希望这是合理的！

如果我调用该函数并试图遍历它：

x = read_compressors()
print("x is:",x)

temporary_counter = 0 #use this to count += active???
for status,data in x.items():
    print(data)
    
    for k,v in data.items():
        print(k,v)

此错误被删除：

200
x is: {'status': 'read_success', 'data': {'cooling_stage_1': {'pv': 'inactive'}, 'cooling_stage_2': {'pv': 'inactive'}, 'cooling_stage_3': {'pv': 'inactive'}, 'cooling_stage_4': {'pv': 'inactive'}}}
read_success
Traceback (most recent call last):
  File "C:\Users\Desktop\rtuTest.py", line 47, in <module>
    for k,v in data.items():
AttributeError: 'str' object has no attribute 'items'

任何小费都很感激..。

x = {'status': 'read_success',
     'data': {'cooling_stage_1': {'pv': 'active'},
              'cooling_stage_2': {'pv': 'active'},
              'cooling_stage_3': {'pv': 'inactive'},
              'cooling_stage_4': {'pv': 'inactive'}
              }
     }




temporary_counter = 0


for stuff in x['data'].values():    
    for clg_cmd in stuff.values():
        if clg_cmd == 'active':
            temporary_counter += 1

print(temporary_counter)
