在此输入代码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 webdriverfrom selenium.common.exceptions import TimeoutExceptionfrom selenium.webdriver.support.ui import WebDriverWait # available since 2.4.0from 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 searchinputElement.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()
