Python Selenium 打印另存为 PDF 等待文件名输入

Question

我正在尝试通过打印对话框将网站另存为 PDF。我的代码允许我另存为 pdf，但要求我输入文件名，我不知道如何将文件名传递给弹出框。附上我的代码:

import time
from selenium import webdriver
import os

class printing_browser(object):
    def __init__(self):
        self.profile = webdriver.FirefoxProfile()
        self.profile.set_preference("services.sync.prefs.sync.browser.download.manager.showWhenStarting", False)
        self.profile.set_preference("pdfjs.disabled", True)
        self.profile.set_preference("print.always_print_silent", True)
        self.profile.set_preference("print.show_print_progress", False)
        self.profile.set_preference("browser.download.show_plugins_in_list",False)
        foxdriver = r'C:\Users\AShen\Documents\Workspace\geckodriver.exe'
        self.driver = webdriver.Firefox(executable_path=foxdriver,firefox_profile = self.profile)
        time.sleep(5)

    def get_page_and_print(self, page):
        self.driver.get(page)
        time.sleep(5)
        self.driver.execute_script("window.print();")

if __name__ == "__main__":
    browser_that_prints = printing_browser()
    browser_that_prints.get_page_and_print('http://www.google.com/')

这几天我也有同样的问题。在这些情况下，我没有使用 pyautogui 就解决了这个问题，因为我使用不同的 PC 和显示器，我不想依赖于点击的位置。

我能够使用 about:config 来解决它...用每个必要的打印(PDF 格式)更改它们。

我在 Ubuntu 中的“PDF 格式”打印机的名称是“Print to File”(在 print_printer 中定义)并且 about:config 的设置需要是这台打印机...例如:print.printer_Print_to_File.print_to_file: true

import os

    def __init__(self):
        self.profile = webdriver.FirefoxProfile()

        self.profile.set_preference('pdfjs.disabled', True)
        self.profile.set_preference('print.always_print_silent', True)
        self.profile.set_preference('print.show_print_progress', False)
        self.profile.set_preference('browser.download.show_plugins_in_list', False)
        
        self.profile.set_preference('browser.download.folderList', 2)
        self.profile.set_preference('browser.download.dir', '')
        self.profile.set_preference('browser.download.manager.showWhenStarting', False)
        self.profile.set_preference('browser.aboutConfig.showWarning', False)
        
        self.profile.set_preference('print.print_headerright', '')
        self.profile.set_preference('print.print_headercenter', '')
        self.profile.set_preference('print.print_headerleft', '')
        self.profile.set_preference('print.print_footerright', '')
        self.profile.set_preference('print.print_footercenter', '')
        self.profile.set_preference('print.print_footerleft', '')

        self.driver.get('about:config')
        time.sleep(1)

browser_that_prints = printing_browser()
browser_that_prints.get_page_and_print('http://www.google.com', os.path.join(os.getcwd(), 'mywebpage.pdf'))
