在回答上一个问题之后，我现在尝试抓取网址的多个页面（给定季节中包含游戏的所有页面）。我还尝试抓取多个父网址（季节）：
from selenium import webdriver import pandas as pd import time url = ['http://www.oddsportal.com/hockey/austria/ebel-2014-2015/results/#/page/', 'http://www.oddsportal.com/hockey/austria/ebel-2013-2014/results/#/page/'] data = [] for i in url: for j in range(1,8): print i+str(j) driver = webdriver.PhantomJS() driver.implicitly_wait(10) driver.get(i+str(j)) for match in driver.find_elements_by_css_selector("div#tournamentTable tr.deactivate"): home, away = match.find_element_by_class_name("table-participant").text.split(" - ") date = match.find_element_by_xpath(".//preceding::th[contains(@class, 'first2')][1]").text if " - " in date: date, event = date.split(" - ") else: event = "Not specified" data.append({ "home": home.strip(), "away": away.strip(), "date": date.strip(), "event": event.strip() }) driver.close() time.sleep(3) print str(j)+" was ok" df = pd.DataFrame(data) print df # ok for six results then socket.error: [Errno 10054] An existing connection was forcibly closed by the remote host # ok for two results, then infinite load # added time.sleep(3) # ok for first result, infinite load after that # added implicitly wait # no result, infinite load
首先，我尝试了两次代码，而没有在第14行隐式等待或在35上进行睡眠。第一个结果给出了套接字错误。在抓取了两个良好的页面后，第二个结果停顿而没有错误。
然后添加如上所述的时间等待，但他们没有帮助。
由于结果不一致，我猜测是在循环结束与下一次运行之间重置连接。我想知道这是否是可能的解决方案以及如何实施。我检查了网站的robots.txt，在设定的时间间隔后看不到任何阻止抓取的内容。
其次，假设刮板获取90％的页面，然后停顿（无限等待）。有没有办法让它在x秒后重试该循环，以保存您已有的内容并从停顿点重试？
您需要做的是：
webdriver
实现方式：
from selenium import webdriver from selenium.webdriver.common.by import By from selenium.webdriver.support.ui import WebDriverWait from selenium.webdriver.support import expected_conditions as EC import pandas as pd urls = [ 'http://www.oddsportal.com/hockey/austria/ebel-2014-2015/results/#/page/', 'http://www.oddsportal.com/hockey/austria/ebel-2013-2014/results/#/page/' ] data = [] driver = webdriver.PhantomJS() driver.implicitly_wait(10) wait = WebDriverWait(driver, 10) for url in urls: for page in range(1, 8): driver.get(url + str(page)) # wait for the page to load wait.until(EC.visibility_of_element_located((By.CSS_SELECTOR, "div#tournamentTable tr.deactivate"))) for match in driver.find_elements_by_css_selector("div#tournamentTable tr.deactivate"): home, away = match.find_element_by_class_name("table-participant").text.split(" - ") date = match.find_element_by_xpath(".//preceding::th[contains(@class, 'first2')][1]").text if " - " in date: date, event = date.split(" - ") else: event = "Not specified" data.append({ "home": home.strip(), "away": away.strip(), "date": date.strip(), "event": event.strip() }) driver.close() df = pd.DataFrame(data) print(df)
