Python phantomjs 加载网页不正确

Question

我在从 link

中提取时遇到问题

http://www.bursamalaysia.com/market/listed-companies/company-announcements/#/?category=FA&sub_category=FA1&alphabetical=All&company=5250

从这个 link 给我带来数据，而不是主页本身。 http://www.bursamalaysia.com/market/listed-companies/company-announcements/#/?category=all

知道为什么会这样吗？我正在使用 PhantomJS selenium 和 beautiful soup 来帮助我。

link ='http://www.bursamalaysia.com/market/listed-companies/company-announcements/#/?category=FA&sub_category=FA1&alphabetical=All&company=5250'
getURLS(link)

def getURLS(url):
    driver = webdriver.PhantomJS(service_args=['--ignore-ssl-errors=true'])
    driver.get(url) # load the web page
    src = driver.page_source
    category_select = Select(driver.find_element_by_xpath('//*[@id="bm_announcement_types"]'))
    category_select.select_by_visible_text("Financial Results")
    category_select2 = Select(driver.find_element_by_xpath('//*[@id="bm_sub_announcement_types"]'))
    category_select2.select_by_visible_text("Financial Results")
    category_select3 = Select(driver.find_element_by_xpath('//*[@id="bm_company_list"]'))
    category_select3.select_by_visible_text("7-ELEVEN MALAYSIA HOLDINGS BERHAD (5250)")
    driver.find_element_by_xpath('//*[@id="bm_company_announcements_search_form"]/input[1]').click()
    src = driver.page_source
    soup = BeautifulSoup(src, 'html5lib')
    link="http://www.bursamalaysia.com/market/listed-companies/company-announcements/#/?category=all"
    getURLS(link)

当您保存源代码时，页面未完全加载您提交的内容 post 因此请尝试等待几秒钟，然后再获取页面源代码：

def getURLS(url):
driver = webdriver.PhantomJS(service_args=['--ignore-ssl-errors=true'])
driver.get(url) # load the web page
time.sleep(5)# waiting for 5 seconds before fetching the source
src = driver.page_source
#Get text and split it
soup = BeautifulSoup(src, 'html5lib')

print soup

要执行下拉 select 您必须按以下方式导入 Select class ：from selenium.webdriver.support.ui import Select 然后您必须 select 这样的下拉元素:

category_select = Select(driver.find_element_by_xpath('//*[@id="bm_announcement_types"]'))
category_select.select_by_visible_text('Financial Results')

在我的示例中，我已经为 -Category- 下拉列表完成了此操作，请按照每个类别的确切步骤操作。请注意，通过 xpath selecting 下拉列表是最好的方法，您可以使用 Google Chrome -> 右键单击元素 -> 检查 -> 右键单击 <select>在右边出现的菜单->Copy->Copy Xpath

当您 select 编辑完所有元素后，您必须单击提交并等待几秒钟加载，然后您将获取源代码。
