1.截取页面图片并保存
在测试过程中，是有必要截图，特别是遇到错误的时候进行截图。
# coding:utf-8 from time import sleep from PIL import Image from selenium import webdriver driver = webdriver.Firefox() driver.get("https://www.baidu.com") sleep(2) driver.get_screenshot_as_file(‘D:\\baidu.png‘) # 把截取的图片存放在D盘 driver.quit()
2.截取某个元素的图
先安装pillow
pip install pillow
# coding:utf-8
from time import sleep
from PIL import Image
from selenium import webdriver
driver = webdriver.Firefox()
driver.get("https://www.baidu.com")
sleep(2)
driver.save_screenshot(‘baidu.png‘) # 截取当前页面全图
element = driver.find_element_by_id("su") # 百度一下的按钮
print("获取元素坐标：")
location = element.location
print(location)
print("获取元素大小：")
size = element.size
print(size)
# 计算出元素上、下、左、右 位置
left = element.location[‘x‘]
top = element.location[‘y‘]
right = element.location[‘x‘] + element.size[‘width‘]
bottom = element.location[‘y‘] + element.size[‘height‘]
im = Image.open(‘baidu.png‘)
im = im.crop((left, top, right, bottom))
im.save(‘D:\\baidu.png‘)
