1、get_screenshot_as_file

from selenium import webdriver

driver = webdriver.Chrome()

driver.get("https://www.baidu.com")

driver.get_screenshot_as_file("./img/save.png")

driver.quit()

get_screenshot_as_file方法只能截取当前页面全屏

2、save_screenshot()

save_screenshot()其实和save_screenshot_as_file()用法相同，两者没什么区别，我们可以看下save_screenshot()的封装

 使用时最后返回的还是save_screenshot_as_file()方法

3、get_screenshot_as_png()

get_screenshot_as_png()方法截取后直接是二进制，并不能像前两个方法一样直接生成图片，我们再写入本地即可。

from selenium import webdriver

from selenium.webdriver.common.by import By

driver = webdriver.Chrome()

driver.get("https://www.baidu.com")

driver.implicitly_wait(10)

img_save = driver.find_element(by=By.XPATH, value="//img[@id='s_lg_img']")

a = driver.get_screenshot_as_png()  # 截取后直接是二进制

with open("./img/two01.jpg", mode="wb")as f:

    f.write(a)

driver.quit()

以上用法是截取页面全屏，还可根据定位的元素截取相应的图片

img_save = driver.find_element(by=By.XPATH, value="//img[@id='s_lg_img']")

a = img_save.screenshot_as_png  # 截取后直接是二进制,无括号

with open("./img/two01.jpg", mode="wb")as f:

    f.write(a)

driver.quit()

4、get_screenshot_as_base64()

get_screenshot_as_base64()截取后的图片是以base64加密过的，需要解密后再写入本地。

import base64

from selenium import webdriver

from selenium.webdriver.common.by import By

driver = webdriver.Chrome()

driver.get("https://www.baidu.com")

driver.implicitly_wait(10)

img_save = driver.find_element(by=By.XPATH, value="//img[@id='s_lg_img']")

a = driver.get_screenshot_as_base64()  # base64加密

b = base64.b64decode(a)  # 解密

with open("./img/two.jpg", mode="wb")as f:

    f.write(b)

driver.quit(

与get_screenshot_as_png()相似的是可根据定位的元素截取相应的图片

img_save = driver.find_element(by=By.XPATH, value="//img[@id='s_lg_img']")

a = img_save.screenshot_as_base64  # base64加密,无括号

b = base64.b64decode(a)  # 解密

with open("./img/two.jpg", mode="wb")as f:

    f.write(b)
