Selenium Chrome另存为pdf更改下载文件夹 [英] Selenium Chrome save as pdf change download folder

问题描述

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，而不是将文件下载到我的默认下载目录.

I want to download a website as pdf file, it's working fine, but it should download the file to a specific path, instead it's just downloading the file to my default download directory.

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();')

顺便说一句，有人想用特定名称保护文件吗?

By the way anyone got an idea to safe the file with a specific name?

推荐答案

download.default_directory 设置仅适用于下载的内容.Chrome 以不同的方式处理保存在页面上的文件.要更改页面打印输出的默认文件夹，只需设置 savefile.default_directory 值.

The download.default_directory setting is only for downloaded content. Chrome treats files saved on the page differently. To change the default folder for a printout of the page, simply set the savefile.default_directory value instead.

因此，为自定义位置打印为 pdf 的完整示例:

So the full example to print to pdf for a custom location:

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();')
