Question

当我试图从oddsportal.com找到体育博彩赔率时，我有这个奇怪的错误。看起来selenium对象不像普通列表那样工作，我不能只是遍历每个url。测试网址应该有效http://www.oddsportal.com/soccer/england/premier-league/（脚本不是为家庭抽奖赔率而写的。）

那我在这里做错了什么？我的剧本：

from selenium import webdriver
from selenium.common.exceptions import NoSuchAttributeException,NoSuchElementException
from selenium.webdriver.common.keys import Keys


class Odds():
    def odds(self,driver,url):

        kertoimet = ['','']
        driver.get(url)
        odds = driver.find_elements_by_xpath("""//*[@id="odds-data table"]/div/table/tbody/tr""")
        for item in odds:
            data = item.text.replace(' ','').split('\n')
            if data[0] == 'Pinnacle':
                kertoimet = [data[1],data[2]]
        return kertoimet

    def odds_finder(self,data,driver):

        for item in data:
            if item.get_attribute('href') != '':
                print(Odds().odds(driver,str(item.get_attribute('href'))))

    def url_finder2(self,URL):

        driver = webdriver.Chrome("/usr/local/bin/chromedriver 2")

        driver.get(URL) #http://www.oddsportal.com/soccer/england/premier-league/
        data = driver.find_elements_by_xpath("""//*[@id="tournamentTable"]/tbody/tr/td/a""")

        Odds().odds_finder(list(data),driver)

Odds().url_finder2(URL)

错误：

Answer 1

您只需再次拨打data，因为状态会发生变化。

尝试修改此2功能。

def odds_finder(self,driver):
        for item in driver.find_elements_by_xpath("//*[@id="tournamentTable"]/tbody/tr/td/a"):
            time.sleep(5)
            if item.get_attribute('href') != '':
                print(Odds().odds(driver, str(item.get_attribute('href'))))

def url_finder2(self, URL):
    driver = webdriver.Chrome("/usr/local/bin/chromedriver 2")
    driver.get(URL)  # http://www.oddsportal.com/soccer/england/premier-league/
    Odds().odds_finder(driver)

Python selenium selenium.common.exceptions.StaleElementReferenceException：
