我使用以下代码使用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保存为基本的html,没有javascripts,图像等。我想将网页保存为完整(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仍然像基本的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。此脚本将弹出网页的save as
对话框。您仍然需要弄清楚如何模拟按下输入以便下载以启动,因为文件对话框超出了selenium的范围(如何操作也取决于操作系统)。
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()
另外我认为遵循 @Amber 建议抓取链接资源可能更简单,因此是更好的解决方案。尽管如此,我认为使用selenium是一个很好的起点,因为br.page_source
将获得整个dom以及javascript生成的动态内容。

您可以使用简单的python库pywebcopy轻松地做到这一点。
对于当前版本: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)
您的download_folder中将包含html,css,js。完全像原始网站一样工作。

要通过@ rajatomar788运行上面的脚本,我必须首先完成以下所有导入:
pip install pywebcopy
pip install pyquery
pip install w3lib
pip install parse
pip install lxml
此后,它出现了一些错误,但我确实将包含构成网页的文件的文件夹充满了。
