美丽的汤不会返回结果

Question

这是我的代码。它不会返回任何错误，但也不会返回任何结果。

import requests
from bs4 import BeautifulSoup

googtrends = requests.get("https://www.google.com/trends/")
soup = BeautifulSoup(googtrends.content)
links = soup.find_all("a", {"class": "trending-story ng-isolate-scope"})

print links

我还没有解决这个问题，我开始研究别的东西，但是我要先用硒试试，尝试使用硒与幻影js或僵尸js，如果仍然不起作用我我会使用pytrends，但我只是检查了它们，你需要一个gmail帐户，我有，但我宁愿尝试让它在没有api的情况下工作。

当我开始工作时，我会回到这里

Answer 1

是这个页面由JS动态呈现 - 让我们尝试更改请求标头（它失败并同样确保JS是原因！）

测试代码 -

import requests
from bs4 import BeautifulSoup

googtrends = requests.get("https://www.google.com/trends/",headers=my_headers)
my_content = googtrends.text.encode('utf-8')
soup = BeautifulSoup(my_content,'html.parser')
links = soup.find_all("a", {"class": "trending-story ng-isolate-scope"},href=True)

#Lets try if we are getting correct content from the site
# That site contains "Apple Inc.‬, ‪App Store‬‬" so let's check it in the got response

print 'Apple Inc.‬, ‪App Store‬‬' in my_content

# It prints false so website is being rendered by JS even header change does not affect

所以尝试在Firefox，Chrome，PhantomJS等中使用selenium等web动态执行JS。 更好的尝试API。
