OpenWeatherMapAPI，如何获取临时数据？

Question

使用Openweather JSON API，我从城市获取数据。我可以检索所有数据，我关注的数据是temp和dt_txt

我尝试过通过这样做来获取临时值，但不起作用：

import requests

def getCity():
    allCityName = ["London"]
    for cityName in allCityName:
        url = "http://api.openweathermap.org/data/2.5/forecast?q="+ cityName +"&appid="
        response = requests.get(url)
        data = response.json()
        print(data["main"]["temp"]

我尝试了许多组合，但似乎总是得到一个错误或没有结果。 任何帮助都将不胜感激

Answer 1

也许你没有意识到这一点，但每个城市都会返回超过1条temp和dt_文本。所以，除非你知道你想要第一个，最后一个，或者中间的某个地方，你不能把它拔出来。或者，如果你想要它们，你必须把它们收集在一个列表中，例如

data = getCity()
for d in data['list']:
    print(d['main']['temp'])
    print(d['dt_txt'])

temps = [d['main']['temp'] for d in data['list']]
