如何显示json的特定部分？

Question

有人可以帮我解决这个python api调用程序吗？

import json
from pprint import pprint
import requests
weather = requests.get('http://api.openweathermap.org/data/2.5/weather?    
q=London&APPID=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx')
pprint(weather.json())

wjson = weather.read()
wjdata = json.load(weather)
print (wjdata['temp_max'])

所以使用这段代码,我试图从天气api获取信息,它正确打印它,但当我想选择某些值时,我得到这个错误.

Traceback (most recent call last):
  File "gawwad.py", line 7, in <module>
    wjson = weather.read()
AttributeError: 'Response' object has no attribute 'read'

Answer 1

.json()是一个内置于requestsJSON解码器,无需单独解析JSON:

import requests

weather = requests.get('http://api.openweathermap.org/data/2.5/weather?q=London&APPID=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx')
wjdata = weather.json()
print (wjdata['temp_max'])
