Python BeautifulSoup 和请求网页抓取

Question

I am trying to get the generated phrase from the following website as a string. https://randomwordgenerator.com/phrase.php I've looked through the html and I believe I've determined where the phrase is located in the html structure.

This is a bit of the html nearby.

<div id="loading_result" class="small-img-results">
    <ol id="result">
        <li> == $0
            <div>
                <span class="support-phrase">Generated Phrase </span>
                <span class="subtle">...</span>
            </div>
        </li>
    </ol>
</div>

In this case, I want the text "Generated Phrase"

This is what I am currently doing

pageLink = "https://randomwordgenerator.com/phrase.php"
pageResponse = requests.get(pageLink, timeout=5)
pageContent = BeautifulSoup(pageResponse.content, "html.parser")

span = pageContent.find_all("span", {"class": "support-phrase"})

The issue is the value of span after this runs is an empty list. I'm new to beautiful soup so this might be a really simple problem, but I have not found anything particularly clear that solves this problem.

Thanks in advance!

edit: I'm now wondering if the issue is that this particular span I'm looking for is nested inside of an which is in a series of divs in the body.

Answer 1

You will need selenium to get the exact value(s) shown on the page. The reason for this is that whilst the total phrases (134) are returned in an array from an xhr ( https://randomwordgenerator.com/json/phrases.json ) which returns json; the actual index/indices (eg function randomiseUniqueNumbers ) to select from this array, the order of items in the array (eg Array.prototype.shuffle = function() ) , and the rules which handle potential clashes I think (eg function getResults ) are all defined in a js file https://randomwordgenerator.com/assets/js-compress/f0351bd03da6dab13a24355fa7deeabd.js?v=1577899960:formatted . The first two of those, at least, use random number generation between the bounds of the array size. There is no seeding and, whilst I think you can write your own versions of these, you are not guaranteed to get the same result as on the page - in fact you are more likely to get a different phrase.

Outline selenium

from selenium import webdriver

d = webdriver.Chrome()
d.get('https://randomwordgenerator.com/phrase.php')
print([i.text for i in d.find_elements_by_css_selector('.support-phrase')])

For a single phrase just use

d.find_element_by_css_selector('.support-phrase').text

Answer 2

If you Go To NetWork Tab under XHR you will get following json url which returns phrases and subtle in json format .You can achieve that without selenium and Beautifulsoup

https://randomwordgenerator.com/json/phrases.json

---

Code Here:

import requests
url='https://randomwordgenerator.com/json/phrases.json'
response=requests.get(url).json()
print(response['data'])
#Print phrase
print(response['data'][0]['phrase'])
#Print meaning
print(response['data'][0]['meaning'])

---

Output here :

Answer 3

from lxml import html
import requests

page = requests.get('https://randomwordgenerator.com/phrase.php')
# get xpath of the string and at end '/text()'
text_xpath= '/html/body/div[2]/div/div[3]/div/div/div[1]/h1/text()' 
tree = html.fromstring(page.content)
page_text =tree.xpath(text_xpath)
print(page_text)

Answer 4

Random Phrase of this page loads through XHR . So you can not find phrase using BeautifulSoup . Use XHR request to get list of phrase.

import requests

pageLink = "https://randomwordgenerator.com/json/phrases.json"

pageResponse = requests.get(pageLink, timeout=5)
print pageResponse.status_code, pageResponse.content

output:

{"data":[ {"phrase":"A Chip on Your Shoulder","meaning":"Being angry about something that happened in the past."}, {"phrase":"A Dime a Dozen","meaning":"Something that is extremely common."}, {"phrase":"A Fool and His Money are Soon Parted","meaning":"It's easy for a fool to lose his/her money."}, ... ]}
