python - Selenium Chrome 另存为 pdf 更改下载文件夹

Question

我想将网站下载为 pdf 文件，它工作正常，但它应该将文件下载到特定路径，而只是将文件下载到我的默认下载目录。

import json
from selenium import webdriver

appState = {
    "recentDestinations": [
        {
            "id": "Save as PDF",
            "origin": "local"
        }
    ],
    "selectedDestinationId": "Save as PDF",
    "version": 2,
    'download.default_directory': 'C:\\Users\\Oli\\Google Drive',
    "download.directory_upgrade": True
}

profile = {'printing.print_preview_sticky_settings.appState': json.dumps(appState)}

chrome_options = webdriver.ChromeOptions()
chrome_options.add_experimental_option('prefs', profile)
chrome_options.add_argument('--kiosk-printing')

driver = webdriver.Chrome(chrome_options=chrome_options)
driver.get('https://www.google.com/')
driver.execute_script('window.print();')

顺便问一下，有人想出用特定名称来保护文件的想法吗？

Answer 1

download.default_directory 设置仅适用于下载的内容。 Chrome 以不同的方式处理页面上保存的文件。要更改页面打印输出的默认文件夹，只需设置 savefile.default_directory 值即可。

因此，在自定义位置打印为 pdf 的完整示例:

import json
from selenium import webdriver

appState = {
    "recentDestinations": [
        {
            "id": "Save as PDF",
            "origin": "local",
            "account": ""
        }
    ],
    "selectedDestinationId": "Save as PDF",
    "version": 2
}

profile = {'printing.print_preview_sticky_settings.appState': json.dumps(appState),
           'savefile.default_directory': 'path/to/dir/'}

chrome_options = webdriver.ChromeOptions()
chrome_options.add_experimental_option('prefs', profile)
chrome_options.add_argument('--kiosk-printing')

driver = webdriver.Chrome(options=chrome_options)
driver.get(url)
driver.execute_script('window.print();')
