使用身份验证从 https 下载文件 [英] Download a file from https with authentication

问题描述

我有一个 Python 2.6 脚本，可以从 Web 服务器下载文件.我希望此脚本传递用户名和密码(用于在获取文件之前进行身份验证)，并将它们作为 url 的一部分传递，如下所示:

I have a Python 2.6 script that downloades a file from a web server. I want this this script to pass a username and password(for authenrication before fetching the file) and I am passing them as part of the url as follows:

import urllib2
response = urllib2.urlopen("http://'user1':'password'@server_name/file")

但是，在这种情况下，我遇到了语法错误.这是正确的方法吗?我对 Python 和编码很陌生.有人可以帮我吗?谢谢！

However, I am getting syntax error in this case. Is this the correct way to go about it? I am pretty new to Python and coding in general. Can anybody help me out? Thanks!

推荐答案

我想您正在尝试通过基本身份验证.在这种情况下，你可以这样处理:

I suppose you are trying to pass through a Basic Authentication. In this case, you can handle it this way:

import urllib2

username = 'user1'
password = '123456'

#This should be the base url you wanted to access.
baseurl = 'http://server_name.com'

#Create a password manager
manager = urllib2.HTTPPasswordMgrWithDefaultRealm()
manager.add_password(None, baseurl, username, password)

#Create an authentication handler using the password manager
auth = urllib2.HTTPBasicAuthHandler(manager)

#Create an opener that will replace the default urlopen method on further calls
opener = urllib2.build_opener(auth)
urllib2.install_opener(opener)

#Here you should access the full url you wanted to open
response = urllib2.urlopen(baseurl + "/file")
