Selenium 学习 8 - 截图

save_screenshot(filename)	截屏png,
get_screenshot_as_file(filename)	截屏png
get_screenshot_as_png()	获取当前屏幕截图的二进制文件数据
get_screenshot_as_base64()	获取当前屏幕截图base64编码字符串

实例

1. save_screenshot(filename)

• 直接传入保存文件名，默认保存在当前目录下

from selenium import webdriver
from time import sleep, localtime, strftime


with webdriver.Chrome() as driver:
    driver.get('https://www.baidu.com/')
    driver.maximize_window()
    sleep(2)

    screentshot_time = strftime('%Y-%m-%d %H-%M-%S', localtime()) + '.png'
    driver.save_screenshot(screentshot_time)

NOTE：这里还犯了一个错误，在使用strftime()时，使用冒号 ‘%Y-%m-%d %H:%M:%S’，结果在运行完成之后既没有保存截屏，也没有异常，原因就是文件在命名时不能包含冒号

• 可以使用相对路径

    screenshot_relpath = '.\\screenshots\\'
    screentshot_time = strftime('%Y-%m-%d %H-%M-%S', localtime())
    driver.save_screenshot(screenshot_relpath + screentshot_time + '.png')

• 还可以使用绝对路径

from selenium import webdriver
from time import sleep, localtime, strftime
import os


with webdriver.Chrome() as driver:
    driver.get('https://www.baidu.com/')
    driver.maximize_window()
    sleep(2)

    # screenshot_relpath = '.\\screenshots\\'
    screenshot_abspath = os.getcwd() + '\\screenshots\\'
    screentshot_time = strftime('%Y-%m-%d %H-%M-%S', localtime())
    driver.save_screenshot(screenshot_abspath + screentshot_time + '.png')

2. get_screenshot_as_file(filename)

同样分别试了没有路径只有文件名，相对路径，以及绝对路径，最终效果与save_screenshot() 一样
