BeautifulSoup返回div类内容

Question

import requests 
from bs4 import BeautifulSoup 

url = 'https://weather.com/weather/today/l/90006:4:US' 
r = requests.get(url) 
html_content = r.text 
soup = BeautifulSoup(html_content, 'lxml') 

weather_row= soup.find('div', {"class" : "today_nowcard-hili"}) 

print weather_row 

我发现类today_nowcard-hili，返回天气的高潮和低谷：即H 84°/L 61°。但上面的代码一直给我None

Answer 1

这是希洛不HILI：

soup.find('div', {"class" : "today_nowcard-hilo"}) 

但是你可以从它返回的数据使用的js插入看到：

<div class="today_nowcard-hilo"> 
<span class="btn-text" data-ng-bind="::'H' | pfTranslate: {context: 'today_nowcard'}"></span> 
<span class="deg-hilo-nowcard" data-gm-wx-temperature="::todayWxcardVm.forecast.items[0].day.daytemp" data-text-to-replace="{{ todayWxcardVm.getProperValue('[[ forecast.day.temperature[0] ]]', '--') }}">[[ forecast.day.temperature[0] || '--' ]]</span> 
<span data-ng-if="::todayWxcardVm.forecast.items[0].day.daytemp"> /</span> 
<span class="btn-text" data-ng-bind="::'L' | pfTranslate: {context: 'today_nowcard'}"></span> 
<span class="deg-hilo-nowcard" data-gm-wx-temperature="::todayWxcardVm.forecast.items[0].day.nighttemp" data-text-to-replace="{{ todayWxcardVm.getProperValue('[[ forecast.night.temperature[0] ]]', '--') }}">[[ forecast.night.temperature[0] || '--' ]]</span> 
<div> 
<span class="btn-text" data-ng-bind="::('UV Index' | pfTranslate: { context: 'weather_terms'})"></span> 
<span data-gm-wx-uv-index="::todayWxcardVm.obs.uvIndex"></span> 
</div> 
</div> 

天气信息通过ajax请求检索：

r = requests.get("https://api.weather.com/v2/turbo/vt1precipitation;vt1currentdatetime;vt1pollenforecast;vt1dailyForecast;vt1observation?units=e&language=en-US&geocode=34.05,-118.29&format=json&apiKey=c1ea9f47f6a88b9acb43aba7faf389d4") 
print(r.json()) 

这将使你：

但是你会使用网站API我不会推荐。有各种api的地段提供免费的计划，你可以用它来获取天气细节，如https://openweathermap.org/appid#get或https://www.wunderground.com/weather/api/d/docs。
