我有一段非常简单的代码使用Python请求0.x但是当我更新到2.x它不再有效。
代码会返回'field1'
中包含的颜色:
import time
import requests
# Read the thingspeak feed to get the current colour
while True:
cheerlights = requests.get('http://api.thingspeak.com/channels/1417/field/1/last.json').json['field1']
print(cheerlights)
time.sleep(16)
当我运行此操作时,我收到此错误:
追踪(最近一次通话): 文件“cheelightsJsonHELP.py”,第7行,in cheerlights = requests.get('http://api.thingspeak.com/channels/1417/field/1/last.json')。json ['field1'] TypeError:'instancemethod'对象没有属性' getitem '
我已经阅读了有关从0.x迁移到2.x的文档,但不幸的是,这不是我的强大领域,有人可以帮忙吗?
答案 0 :(得分:3)
response.json()
现在是方法,过去它是一个属性;添加()
来调用它:
response = requests.get('http://api.thingspeak.com/channels/1417/field/1/last.json')
cheerlights = response.json()['field1']
演示:
>>> import requests
>>> response = requests.get('http://api.thingspeak.com/channels/1417/field/1/last.json')
>>> response.json()['field1']
'orange'
