网页抓取速度如何? [英] How to web scrape a speed amount?

问题描述

我想知道如何用python抓取速度量是Fast.com网站

I was wondering how to web scrape the speed amount is the Fast.com website with python

我做了一些努力，这是我目前所做的:

I did some effort, here is what I've done so far:

import requests
from bs4 import BeautifulSoup

response = requests.get('https://fast.com/', headers = {"User-Agent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_4) AppleWebKit/600.7.12 (KHTML, like Gecko) Version/8.0.7 Safari/600.7.12"})
soup = BeautifulSoup(response.text, 'lxml')
speed = soup.find('span', {'id' : 'speed-value'}).text

print(speed)

输出总是0"；有时它会给我一个错误

The output is always "0" and sometimes it gives me an error

我的目标是获得扫描后网站上显示的速度数(以 MB/s 为单位).

My goal is to get the speed number in MB/s as shown in the website after the scan.

我忘了做什么?

推荐答案

根据我的个人经验，BeautifulSoups 更适合静态页面.我会推荐 Selenium 以获得更多动态使用.它将允许在 javascript 等加载后进行访问，以便更轻松地进行网页抓取.

BeautifulSoups is more for Static Pages from my personal experience. I would recommend Selenium for more dynamic usage. It would allow for access after javascript and etc has loaded for easier web scraping.

from selenium import webdriver
driver_path = r"C:\chromedriver.exe"
driver = webdriver.Chrome(driver_path)

MBPS_CLASS = "speed-results-container"

driver.get("https://fast.com/")
while True:
    print(driver.find_elements_by_class_name(MBPS_CLASS)[0].text)
    # driver.find_element_by_id("speed-value").text # This works with ID also
