Python 美丽的汤检索给出错误响应'NoneType object 没有属性 getText

Question

Im trying to retrieve data from a google.com query using requests library and beautiful soup library. Im tearing my hair out. Whatever version of code I try I get an error.

This is the html code:

<div class="LGOjhe" data-attrid="wa:/description" aria-level="3" role="heading" data-hveid="CAYQAA">
<span class="ILfuVd NA6bn">
<span class="hgKElc">
Right-click the speaker icon and select &quot;Open Sound Settings.&quot; 3. Scroll down to &quot;Input.&quot; Windows will show you which <b>microphone</b> is currently your default — in other words, which one it&#39;s using right now — and a blue bar showing your volume levels. Try talking into your <b>microphone</b>.
</span>
</span>

I use the following code:

        page = rq.get('http://www.google.com/search?q=where%20is%20my%20microphone',  headers = hd)
        soup = BeautifulSoup(page.content, 'html.parser')
        #answer = soup.find('span', {'class_': 'hgKElc'}).getText()
        answer = soup.find('div', {'class_': 'kJ442'}).getText()

I get an error that the response of none does not have a getText() method. which means my retrieval method has failed:

File "C:\Users\User\Documents\study\PythonProjectVoice\PythonVoice03.py", line 115, in respond
    answer = soup.find('div', {'class_': 'kJ442'}).getText()
AttributeError: 'NoneType' object has no attribute 'getText'

Any answers much appreciated.

Answer 1

There are different things, that could be improved, but the error occurred cause there is no <div> with a class like kJ442

To get the text of the <span> use:

soup.find('span', {'class': 'hgKElc'}).get_text()

Example

from bs4 import BeautifulSoup

html='''
<div class="LGOjhe" data-attrid="wa:/description" aria-level="3" role="heading" data-hveid="CAYQAA">
<span class="ILfuVd NA6bn">
<span class="hgKElc">
Right-click the speaker icon and select &quot;Open Sound Settings.&quot; 3. Scroll down to &quot;Input.&quot; Windows will show you which <b>microphone</b> is currently your default — in other words, which one it&#39;s using right now — and a blue bar showing your volume levels. Try talking into your <b>microphone</b>.
</span>
</span>
'''
soup = BeautifulSoup(html,'html.parser')
soup.find('span', {'class': 'hgKElc'}).get_text()
