如何在Python + Webkit + Gtk中下载文件浏览器？ [英] How to download a file browser in Python+Webkit+Gtk?

问题描述

这是Python Webkit Gtk中的简单浏览器：

Here is a simple browser in Python Webkit Gtk:

#!/usr/bin/python

import gtk
import webkit

view = webkit.WebView()
sw = gtk.ScrolledWindow()

sw.add(view)

win = gtk.Window(gtk.WINDOW_TOPLEVEL)

win.add(sw)

win.show_all()

view.open("https://www.kernel.org/")

gtk.main()

浏览效果很好。不幸的是，在本地计算机上保存文件不起作用。我找不到准备好的解决方案。我不需要进度条，文件夹选择，我想点击链接导致下载。你知道将文件保存到目录/ home / user的最简单的方法吗？

Browsing works perfectly. Unfortunately, it does not work to save files on the local computer. I could not find a ready solution. I do not need a progress bar, folder selection, I want to click on the link resulted in downloading. Do you know the easiest way to save files to the directory /home/user?

推荐答案

正如在 docs ，你有连接到 mime-type-policy-decision-requested-requests-requested 和下载请求信号。

As it says in the docs, you have to connect to the mime-type-policy-decision-requested and download-requested signals.

view.connect('download-requested', download_requested)
view.connect('mime-type-policy-decision-requested', policy_decision_requested)

然后，您检查mime类型，并决定是否要下载：

Then you check the mime-type and decide if you want to download it:

def policy_decision_requested(view, frame, request, mimetype, policy_decision):
    if mimetype != 'text/html':
        policy_decision.download()
        return True

下载请求之后，您可以让 WebKit.Download 对象处理下载或（在这种情况下）使用python：

When download-requested is emitted afterwards, you can let the WebKit.Download object handle the download or (in this case) do it with python:

def download_requested(view, download):
    name = download.get_suggested_filename()
    path = os.path.join(
        GLib.get_user_special_dir(GLib.UserDirectory.DIRECTORY_DOWNLOAD),
        name
    )
    urlretrieve(download.get_uri(), path)  # urllib.request.urlretrieve
    return False
