I'm trying to extract the span tag content from the google translate website. The content is the translated result which has the id="result_box". When tried to print the contents, it returns None value.

请在此处

import requests
from bs4 import BeautifulSoup

r = requests.get("https://translate.google.co.in/?rlz=1C1CHZL_enIN729IN729&um=1&ie=UTF-8&hl=en&client=tw-ob#en/fr/good%20morning")

soup = BeautifulSoup(r.content, "lxml")
spanner = soup.find(id = "result_box")

result = spanner.text

推荐答案

请求未执行JavaScript，您可以使用 selenium 和 PhantomJS 进行这样的无头浏览:

Requests doesn't execute JavaScript, you could use selenium and PhantomJS for the headless browsing like this:

from bs4 import BeautifulSoup
from selenium import webdriver

url = "https://translate.google.co.in/?rlz=1C1CHZL_enIN729IN729&um=1&ie=UTF-8&hl=en&client=tw-ob#en/fr/good%20morning"
browser = webdriver.PhantomJS()
browser.get(url)
html = browser.page_source

soup = BeautifulSoup(html, 'lxml')
spanner = soup.find(id = "result_box")
result = spanner.text

这给出了我们预期的结果:

This gives our expected result:

>>> result
'Bonjour'
