导包

from selenium import webdriver

创建浏览器对象(以chrome为例)

driverpath = r\' \'# 驱动器路径(chromedriver.exe)
driver = webdriver.Chrome(executable_path=driverpath)

demo

import time
from selenium import webdriver

url = \'https://www.baidu.com\'
driverPath = r\'\' # 驱动器路径
driver = webdriver.Chrome(executable_path=driverPath)
driver.get(url)
driver.maximize_window() # 最大化页面
time.sleep(3)
driver.quit()

基本函数

尺寸，位置

driver.minimize_window()  #最大化页面
driver.minimize_window()  #最小化页面
driver.set_window_size(200, 100)  #设置窗口大小
print(\'窗口尺寸:\' + str(driver.get_window_size())) #窗口大小
driver.set_window_position(200, 300) # 设置窗口位置

关闭

driver.quit()
driver.close()

页面基本操作

driver.get(url) # 获取一个页面
driver.back() # 回退
driver.forward() # 前进

demo

import time
from selenium import webdriver

url1 = \'https://www.baidu.com\'
url2 = \'https://www.bilibili.com\'
driverPath = r\'C:\\Users\\29273\\AppData\\Local\\Programs\\Python\\Python38-32\\chromedriver.exe\'
driver = webdriver.Chrome(executable_path=driverPath)
driver.set_window_position(200, 300)
driver.get(url1)
time.sleep(5)
driver.get(url2)
time.sleep(5)
driver.back()
time.sleep(5)
driver.close()

元素定位以及数据输入

div标签中的属性来进行定位

id,classname,name,tagname,partial link text,link text,css selector

例如下列a标签中的classname为username

driver.find_element_by_class_name(\"username\")

driver.find_element_by_class_name(\"btn.btn_big.btn_error\")

# 部分函数
driver.find_element_by_xpath(\'/html/body/div[1]/div[2]/div[3]/div[2]/div[1]/dl/dd/div[1]/a\')
driver.find_element_by_css_selector(\'body > div.wrap > div.main_wrap > div.main.cc > div.main_sidebar > div.box_wrap.user_info > dl > dd > div.name > a\')
driver.find_element_by_id(value)
driver.find_element_by_name(value)
driver.find_element_by_class_name(value)
driver.find_element_by_tag_name(value)
driver.find_element_by_link_text(value)
driver.find_element_by_partial_link_text(value)

对数据框输入数据

driver.find_element_by_name(\"username\").send_keys(\"giao\")

点击事件

driver.find_element_by_xpath(\'//*[@id=\"J_register_form\"]/div/dl[5]/dd/button\').click()

练习一（简单网页注册）

http://47.107.178.45/phpwind/

import time
from selenium import webdriver

url = r\'http://47.107.178.45/phpwind/\'
driverPath = r\'C:\\Users\\29273\\AppData\\Local\\Programs\\Python\\Python38-32\\chromedriver.exe\'
driver = webdriver.Chrome(executable_path=driverPath)
driver.get(url)
registerBtn = driver.find_element_by_xpath(\'//*[@id=\"J_login_form\"]/dl/dd[2]/a\')
registerBtn.click()
time.sleep(5)
driver.find_element_by_name(\"username\").send_keys(\"giao\")
driver.find_element_by_name(\"password\").send_keys(\"giaogiao\")
driver.find_element_by_name(\"repassword\").send_keys(\'giaogiao\')
driver.find_element_by_name(\"email\").send_keys(\'giao@qq.com\')
driver.find_element_by_xpath(\'//*[@id=\"J_register_form\"]/div/dl[5]/dd/button\').click()
time.sleep(10)
driver.quit()

练习二

打开某民宿网站->输入城市->选择人数->点击查看详情

import time
from selenium import webdriver

city = input(\'请输入你想查询的城市：\')
adult = input(\'请输入大人人数：\')
teen = input(\'请输入孩子人人数：\')
baby = input(\'请输入婴儿人数：\')

url = \"https://www.airbnb.cn/?logo=1\"

driverPath = r\'C:\\Users\\29273\\AppData\\Local\\Programs\\Python\\Python38-32\\chromedriver.exe\'
driver = webdriver.Chrome(executable_path=driverPath)
driver.get(url)
city_input = driver.find_element_by_id(\"Koan-via-HeaderController__input\")
city_input.send_keys(city + \"\\n\")

time.sleep(5)

driver.find_element_by_name(\"query\").click()
time.sleep(3)

for i in range(int(adult)):
    driver.find_element_by_xpath(
        \'//*[@id=\"menuItemComponent-guest_picker\"]/div/div/div/div[1]/div/div/div[1]/div/div/div/div/div/div[2]/div/div[3]/button\').click()
time.sleep(4)
for i in range(int(teen)):
    driver.find_element_by_xpath(
        \'//*[@id=\"menuItemComponent-guest_picker\"]/div/div/div/div[1]/div/div/div[2]/div/div/div/div/div/div[2]/div/div[3]/button\').click()
time.sleep(3)
for i in range(int(baby)):
    driver.find_element_by_xpath(
        \'//*[@id=\"menuItemComponent-guest_picker\"]/div/div/div/div[1]/div/div/div[3]/div/div/div/div/div/div[2]/div/div[3]/button\').click()
time.sleep(5)


driver.find_element_by_class_name(\"_fhph4u\")[0].click()
time.sleep(20)

练习三

爬取某站入站必看视频信息

import time
from selenium import webdriver

url = \'https://www.baidu.com\'

driverPath = r\'C:\\Users\\29273\\AppData\\Local\\Programs\\Python\\Python38-32\\chromedriver.exe\'
driver = webdriver.Chrome(executable_path=driverPath)
res = driver.find_elements_by_class_name(\"video-card\")
for i in range(len(res)):
    print(\'第\' + str(i) + \'个视频\')
    print(\'up主：\' + str(res[i].find_element_by_class_name(\"up-name__text\").text))
    print(\'视频名称：\' + str(res[i].find_element_by_class_name(\"video-name\").text))
