将屏幕截图从selenium保存到绝对路径

Question

我目前正在尝试编写一个脚本（用于插入Django项目），以使用Selenium拍摄网站的完整页面截图

一切似乎都运行正常-路径（fullimsavepath）构建正常（因此我可以看到输出的print语句），selenium没有报告任何错误，脚本也可以正常退出。但是,

当我在提供的路径中查找实际屏幕截图时，它并不存在。我做错了什么？这与相对路径和绝对路径有关吗

在pipenv内部的Windows上运行Python 3.8

代码：

import time
import os
from sitehawk.settings import BASE_DIR
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from datetime import datetime, date


def takescreenshot(url='http://www.google.com', filename='testpng1'):

    options = webdriver.ChromeOptions()
    options.headless = True
    # Need to replace executable path with environment variable or similar for production?
    # At the moment it's an absolute path to the driver
    driver = webdriver.Chrome(options=options,executable_path=r'C:/Users/gapbr/Documents/dev/sitehawk/sitehawk-project/screenshots/driver/chromedriver.exe')
    driver.get(url)

    # Set the path where the image should be saved
    actualdate = datetime.now()
    yr = actualdate.strftime('%Y')
    mn = actualdate.strftime('%m')
    filepng = filename+'.png'
    fullimsavepath = os.path.join(BASE_DIR,'screenshots','captured-files',yr,mn,filepng)
    print(fullimsavepath)

    # Take the screenshot
    S = lambda X: driver.execute_script('return document.body.parentNode.scroll'+X)
    driver.set_window_size(S('Width'),S('Height')) # May need manual adjustment
    driver.find_element_by_tag_name('body').screenshot(fullimsavepath)

    driver.quit()

我对python知之甚少。但是，为了供您参考，我在我的C#项目中使用了下面的代码来截图。我希望你能从中得到一些想法：

static public void getCapture(string No = "1")
    {
        //Screenshot
        Screenshot ss = ((ITakesScreenshot)Tests.driver).GetScreenshot();
        DateTime dt = DateTime.Now;
        //Saving_the_screenshot_with_a_filename
        var title = dt.ToString("yyyyMMddHHmm") + "_" + No + ".png";
        string file = System.IO.Path.Combine(appSettings.Settings["ScreenShotPath"].Value);
        if (string.IsNullOrEmpty(file))
        {
            file = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
        }
        ss.SaveAsFile(file + @"\" + title);
    }

也许Python的文字量比Java翻了一番。尝试在路径中将斜线加倍，如下所示：

driver = webdriver.Chrome(options=options,executable_path=r'C://Users/gapbr//Documents//dev//sitehawk//sitehawk-project//screenshots//driver//chromedriver.exe')
