我正在尝试提取此页面中“Nb B”列的所有数据： https: //www.coteur.com/cotes-foot.php
当我从 Ubuntu PC 运行我的代码时，它运行得很好，但是当我尝试使用 EC2 Ubuntu 时，它并没有给我很好的回报。
这是我的服务器：ubuntu/images/hvm-ssd/ubuntu-bionic-18.04-amd64-server-20200611 (ami-0a63f96e85105c6d3)
这是 python 脚本：
#!/usr/bin/python3
# -*- coding: utf-8 -*-
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = Options()
options.headless = True
options.add_argument("window-size=1400,800")
options.add_argument("--no-sandbox")
options.add_argument("--disable-gpu")
driver = webdriver.Chrome(options=options)
driver.get('https://www.coteur.com/cotes-foot.php')
#Store url associated with the soccer games
url_links = []
for i in driver.find_elements_by_xpath('//a[contains(@href, "match/cotes-")]'):
url_links.append(i.get_attribute('href'))
print(len(url_links), '\n')
nb_bookies = []
for i in driver.find_elements_by_xpath('//tr[@id and @role="row" ]/td[last()]'):
nb_bookies.append(i.text)
print(nb_bookies)
这是输出：
