问题描述
所以我尝试使用 Python 登录 Quora，然后抓取一些东西.
So I'm trying to login to Quora using Python and then scrape some stuff.
我正在使用 Selenium 登录该站点.这是我的代码:
I'm using Selenium to login to the site. Here's my code:
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
driver = webdriver.Firefox()
driver.get('http://www.quora.com/')
username = driver.find_element_by_name('email')
password = driver.find_element_by_name('password')
username.send_keys('email')
password.send_keys('password')
password.send_keys(Keys.RETURN)
driver.close()
现在的问题:
查找和填写登录表单花了大约 4 分钟，速度非常慢.我可以做些什么来加快进程?
It took ~4 minutes to find and fill the login form, which painfully slow. Is there something I can do to speed up the process?
当它登录时，我如何确保没有错误?换句话说，我如何检查响应代码?
When it did login, how do I make sure there were no errors? In other words, how do I check the response code?
如何使用 selenium 保存 cookie，以便在登录后继续抓取?
How do I save cookies with selenium so I can continue scraping once I login?
如果没有办法让selenium更快，还有其他的登录方式吗?(Quora 没有 API)
If there is no way to make selenium faster, is there any other alternative for logging in? (Quora doesn't have an API)
推荐答案
我遇到了类似的问题，使用 ChromeDriver 在 Python selenium 中调用 find_elements_xxx 非常慢.我最终将问题追溯到我在 find_element_xxx() 调用之前所做的 driver.implicitly_wait() 调用；当我拿出来时，我的 find_element_xxx() 调用跑得很快.
I had a similar problem with very slow find_elements_xxx calls in Python selenium using the ChromeDriver. I eventually tracked down the trouble to a driver.implicitly_wait() call I made prior to my find_element_xxx() calls; when I took it out, my find_element_xxx() calls ran quickly.
现在，我知道这些元素在我调用 find_elements_xxx() 时就在那里.所以我无法想象为什么implicit_wait会影响这些操作的速度，但它确实影响了.
Now, I know those elements were there when I did the find_elements_xxx() calls. So I cannot imagine why the implicit_wait should have affected the speed of those operations, but it did.
