selenium的安装 在python环境安装的基础上安装setuptools 后安装pip,并使用命令 ‘pip install selenium’安装selenium(不同语言参照官网文档)
selenium除了使用firefox driver可以使用chrome drvier、IE driver、Opera driver、android driver和ios driver(只用过chrome和Ie,其他没实践过) 以下是官方给出的一个例子:
from selenium import webdriver
from selenium.common.exceptions import TimeoutException
from selenium.webdriver.support.ui import WebDriverWait # available since 2.4.0
from selenium.webdriver.support import expected_conditions as EC # available since 2.26.0
# Create a new instance of the Firefox driver
driver = webdriver.Firefox()
# go to the google home page
driver.get("http://www.google.com")
# the page is ajaxy so the title is originally this:
print driver.title
# find the element that's name attribute is q (the google search box)
inputElement = driver.find_element_by_name("q")
# type in the search
inputElement.send_keys("cheese!")
# submit the form (although google automatically searches now without submitting)
inputElement.submit()
try: # we have to wait for the page to refresh, the last thing that seems to be updated is the title WebDriverWait(driver, 10).until(EC.title_contains("cheese!")) # You should see "cheese! - Google Search" print driver.title finally: driver.quit()
