我尝试通过“http://weixin.sogou.com/”抓取包含关键词的微信公众号

但是我发现我必须使用两次两次ActionChains(driver).move_to_element(nextpage).click().perform(),它仍然可以工作,并转到下一页!在

谁能告诉我为什么和如何修复!谢谢您!在

源代码如下,很抱歉评论是中文的。在

# coding=utf-8
import time
from selenium import webdriver
from selenium.webdriver import ActionChains
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

key = u"江南大学"  #搜索的关键词
driver = webdriver.Chrome()
driver.get("http://weixin.sogou.com/")
assert u'搜狗微信' in driver.title
elem = driver.find_element_by_id("upquery")
elem.clear()
elem.send_keys(key)
button = driver.find_element_by_class_name("swz2") #搜索公众号
button.click()
WebDriverWait(driver,10).until(
    EC.title_contains(key)
)
count = 0
while True:
    for i in range(10):
        try:
            wechat_name = driver.find_element_by_xpath("//*[@id=\"sogou_vr_11002301_box_{}\"]/div[2]/h3".format(i)).text
            print wechat_name
            wechat_id = driver.find_element_by_xpath("//*[@id=\"sogou_vr_11002301_box_{}\"]/div[2]/h4/span/label".format(i)).text
            print wechat_id
            wechat_intro = driver.find_element_by_xpath("//*[@id=\"sogou_vr_11002301_box_{}\"]/div[2]/p[1]/span[2]".format(i)).text
            print wechat_intro
            print "*************************"
            count += 1
        except:
            pass
    try:
        nextpage = driver.find_element_by_xpath("//*[@id=\"sogou_next\"]") #下一页的按钮
        actions = ActionChains(driver)
        actions.move_to_element(nextpage)
        actions.click().
        actions.perform()
        actions = ActionChains(driver)
        actions.move_to_element(nextpage)
        actions.click().
        actions.perform()
    except Exception,e:
        print e
        break
driver.quit()
print count
