Question

我正在尝试导航到多个页面并从每个页面下载PDF。这些页面由同一站点托管，只是URL不同，因此要下载的xpath都相同。我拥有的当前代码有效，但是我是Python初学者，我敢肯定有一种更简单的方法来合并它-只是很难弄清楚如何做到！

我尝试使用for循环，但出现一些错误。

这就是我现在正在使用的：

one ='urlone'
two = 'urltwo'
three = 'urlthree'

try:
    download = "C:/pathtodownload"
    driver = webdriver.Chrome('driver.exe', chrome_options=options)

    driver.get(one)
    driver.maximize_window()
    actions = driver.find_element_by_xpath('xpathhere')
    actions.click()
    time.sleep(4)

    driver.get(two)
    driver.maximize_window()
    actions = driver.find_element_by_xpath('xpathhere')
    actions.click()
    time.sleep(4)

    driver.get(three)
    driver.maximize_window()
    actions = driver.find_element_by_xpath('xpathhere')
    actions.click()
    time.sleep(4)

finally:
   driver.quit

我相信我应该可以执行类似的操作，但是我收到了错误消息。 WebDriverException：消息：未知错误：“ url”必须为字符串

urls = ['urlone', 'urltwo', 'urlthree']

try:
    download = "C:/pathtodownload"
    driver = webdriver.Chrome('driver.exe', chrome_options=options)

for url in urls:
    driver.get(urls)
    driver.maximize_window()
    actions = driver.find_element_by_xpath('xpathhere')
    actions.click()
    time.sleep(4)

我发现了错误。

urls = ['urlone', 'urltwo', 'urlthree']

try:
    download = "C:/pathtodownload"
    driver = webdriver.Chrome('driver.exe', chrome_options=options)

for url in urls:
    driver.get(url) # Here I changed urls that you used in your code to url
    driver.maximize_window()
    actions = driver.find_element_by_xpath('xpathhere')
    actions.click()
    time.sleep(4)

基本上在注释行中使用url，您试图在仅接受字符串的.get（）方法中提供整个url列表。

如何改进：使用Python浏览多个URL
