selenium之安装和登陆操作举例

安装selenium：

python -m pip install selenium-3.4.3-py2.py3-none-any.whl

下载对应浏览器版本的驱动，且在环境变量PATH中指定驱动程序的存放路径，否则需要指定驱动文件路径。

代码举例：

# selenium登录操作举例

import os, time

from selenium import webdriver

# 指定浏览器安装位置

chrome_path = "C:\\Users\\nriet\AppData\Local\Google\Chrome\Application\chrome.exe"

os.environ["webdriver.chrome.bin"] = os.path.abspath(chrome_path)

# 指定浏览器驱动路径

driver_path = "D:\\Program Files\\Python36\\chromedriver.exe"

driver = webdriver.Chrome(executable_path=driver_path)

time.sleep(1)

# 模拟登录操作

driver.get("http://192.168.20.179:8080/YZWXTQ/login.do")

driver.maximize_window()

driver.find_element_by_id('name').send_keys('username')

driver.find_element_by_id('password').send_keys('password')

time.sleep(2)

driver.find_element_by_id('login-btn').click()

time.sleep(3)

driver.quit()
