我正在使用以下代码使用 Python 保存网页:

import urllib
import sys
from bs4 import BeautifulSoup

url = 'http://www.vodafone.de/privat/tarife/red-smartphone-tarife.html'
f = urllib.urlretrieve(url,'test.html')

问题:此代码将 html 保存为没有 javascript、图像等的基本 html。我想将网页保存为完整的(就像我们在浏览器中有选项一样)

更新:我现在使用以下代码来保存 webapge 的所有 js/images/css 文件,以便它可以保存为完整的网页,但我的输出 html 仍然像基本 html 一样保存:

import pycurl
import StringIO

c = pycurl.Curl()
c.setopt(pycurl.URL, "http://www.vodafone.de/privat/tarife/red-smartphone-tarife.html")

b = StringIO.StringIO()
c.setopt(pycurl.WRITEFUNCTION, b.write)
c.setopt(pycurl.FOLLOWLOCATION, 1)
c.setopt(pycurl.MAXREDIRS, 5)
c.perform()
html = b.getvalue()
#print html
fh = open("file.html", "w")
fh.write(html)
fh.close()

尝试使用selenium模拟您的浏览器。此脚本将弹出save as网页对话框。由于文件对话框超出了 selenium 的范围(您的操作方式也取决于操作系统),因此您仍然必须弄清楚如何模拟按 Enter 以开始下载。

from selenium import webdriver
from selenium.webdriver.common.action_chains import ActionChains
from selenium.webdriver.common.keys import Keys

br = webdriver.Firefox()
br.get('http://www.google.com/')

save_me = ActionChains(br).key_down(Keys.CONTROL)\
         .key_down('s').key_up(Keys.CONTROL).key_up('s')
save_me.perform()

此外,我认为遵循@Amber获取链接资源的建议可能更简单,因此是更好的解决方案。不过,我认为使用 selenium 是一个很好的起点,因为它br.page_source可以让你了解整个 dom 以及 javascript 生成的动态内容。

您可以使用简单的 python 库 pywebcopy 轻松做到这一点。

当前版本:5.0.1

from pywebcopy import save_webpage

url = 'http://some-site.com/some-page.html'
download_folder = '/path/to/downloads/'    

kwargs = {'bypass_robots': True, 'project_name': 'recognisable-name'}

save_webpage(url, download_folder, **kwargs)

您将在您的 download_folder 中拥有 html、css、js。完全像原始网站一样工作。

要让@rajatomar788 上面的脚本运行,我必须首先执行以下所有导入:

要运行 pywebcopy,您需要安装以下软件包:

pip install pywebcopy 
pip install pyquery
pip install w3lib
pip install parse 
pip install lxml

之后它出现了一些错误,但我确实得到了包含构成网页的文件的文件夹。
