一、今天小編就為大家分享一篇對 Python 獲取螢幕截圖的 3 種方法詳解

1、採用 selenium 中的兩種截圖方法

• 方法一：save_screenshot()
• 方法二：get_screenshot_as_file()
  • 用法一樣，都是擷取瀏覽器當前窗口裡的內容

from PIL import ImageGrab
import time

def screenshot_image1(webdriver, image_path):
    nowTime = time.strftime("%Y-%m-%d_%H-%M-%S")
    imageName = image_path + "
 
/" + "bug_image{}.png".format(nowTime)
    webdriver.save_screenshot(imageName)

def screenshot_image2(webdriver, image_path):
    nowTime = time.strftime("%Y-%m-%d_%H-%M-%S")
    imageName = image_path + "/" + "bug_image{}.png".format(nowTime)
    webdriver.get_screenshot_as_file(imageName)

2、方法三：Windows 環境下截圖需要用到 PIL 庫，使用 pip 安裝 PIL 庫

• pip install pillow
• 函式引數介紹如下，預設為全屏截圖

"""
第一個引數 開始截圖的x座標
第二個引數 開始截圖的y座標
第三個引數 結束截圖的x座標
第四個引數 結束截圖的y座標
"""
bbox = (0, 0, 1920, 1080)
im = ImageGrab.grab(bbox)   # grab() 預設截全屏

• 用例輸出如下

import time
import unittest
from selenium import webdriver
from selenium.webdriver.common.by import By
from screenshot.ScreenShotFunc import
 
 *

class Test_Baidu_Search(unittest.TestCase):

    def setUp(self) -> None:
        self.driver = webdriver.Chrome()
        self.driver.get("https://www.baidu.com")
        self.driver.maximize_window()
        self.driver.implicitly_wait(10)

    def tearDown(self) -> None:
        time.sleep(2)
        self.driver.quit()

    def test01(self):
        self.driver.find_element(By.ID, "kw").send_keys("Python")
        time.sleep(2)
        self.driver.find_element(By.ID, "su").click()
        # time.sleep(3)
        title = self.driver.title
        # 呼叫第一種方法實現截圖
        """
        try:
            self.assertIn("Python", title)
        except Exception as E:
            image_path = "D:\work_doc\CodeFile\dcs_class6\screenshot_image"
            screenshot_image1(self.driver, image_path)
            raise AssertionError(E)
        """
        # 呼叫第二種方法實現截圖
        """
        try:
            self.assertIn("Python", title)
        except Exception as E:
            image_path = "D:\work_doc\CodeFile\dcs_class6\screenshot_image"
            screenshot_image2(self.driver, image_path)
            raise AssertionError(E)
        """
        # 呼叫第三種方法實現截圖
        try:
            self.assertIn("Python", title)
        except Exception as E:
            image_path = "D:\work_doc\CodeFile\dcs_class6\screenshot_image"
            screen_shot(image_path)
            raise AssertionError(E)

if __name__ == '__main__':
    unittest.main()
