我试图在给出用户输入的情况下浏览Instagram页面。我能够访问该页面。页面加载,然后找到类,然后代码中断。这是我的代码:
from selenium import webdriver
from selenium.webdriver.common.action_chains import ActionChains
from selenium.webdriver.common.keys import Keys
from bs4 import BeautifulSoup
import urllib.request, urllib.parse, urllib.error
import time
def get_posts(tag, user_count):
'''Getting html of page to be scrape for
hrefs that will get me the user names'''
print("getting page")
url = "https://www.instagram.com/explore/tags/" + tag + "/"
try:
driver = webdriver.Chrome()
driver.get(url)
print("successfully requested site")
except:
print("Unable to reach site")
quit()
browser = driver.find_element_by_class_name('_si7dy')
actions = ActionChains(browser)
for i in range(user_count):
actions = actions.send_keys(Keys.TAB)
time.sleep(0.5)
actions.perform()
soup = BeautifulSoup(driver.page_source, 'lxml')
try:
posts = soup.find_all("div", class_ = ["_mck9w","_gvoze","_f2mse"])
except:
print("No links found")
quit()
print("Length of posts: ",(len(posts)))
print(len(posts))
print(type(posts))
print("All Done")
driver.close()
return posts
我一直收到这个错误:
packages\selenium\webdriver\common\action_chains.py", line 69, in __init__
if self._driver.w3c:
AttributeError: 'WebElement' object has no attribute 'w3c'
我已经搜索过但没有找到关于w3c的任何信息。我之前从未标记过页面,因此使用此处的答案:Send multiple tab key presses with selenium。
ActionChains似乎是在页面上多次标签的最佳方式,但如果有人有更好的方法,我愿意尝试。
答案 0 :(得分:2)

应该收到ActionChains
,但您发送的是WebDriver
WebElement
