Python 处理 URL 的用户名和密码

Python handling username and password for URL

提问by Anthony Honciano

Messing with Python and I'm trying to use this https://updates.opendns.com/nic/update?hostname=, when you got to the URL it will prompt a username and password. I've been looking around and I found something about password managers, so I came up with this:

与 Python 混为一谈，我正在尝试使用此https://updates.opendns.com/nic/update?hostname=，当您到达 URL 时，它会提示输入用户名和密码。我一直在环顾四周，发现了一些关于密码管理器的信息，所以我想出了这个：

urll = "http://url.com"
username = "username"
password = "password"

passman = urllib2.HTTPPasswordMgrWithDefaultRealm()

passman.add_password(None, urll, username, password)

authhandler = urllib2.HTTPBasicAuthHandler(passman)

urllib2 = urllib2.build_opener(authhandler)

pagehandle = urllib.urlopen(urll)

print (pagehandle.read())

This all works, but it's prompting the username and password via the command line, requiring the user's interaction. I want it to automatically enter those values. What am I doing wrong?

这一切都有效，但它通过命令行提示用户名和密码，需要用户交互。我希望它自动输入这些值。我究竟做错了什么？

Your request url is "RESTRICTED".

您的请求网址是“受限”。

If you try this code it will tell you:

如果您尝试此代码，它会告诉您：

import urllib2
theurl = 'https://updates.opendns.com/nic/update?hostname='
req = urllib2.Request(theurl)
try:
    handle = urllib2.urlopen(req)
except IOError, e:
    if hasattr(e, 'code'):
        if e.code != 401:
            print 'We got another error'
            print e.code
        else:
            print e.headers
            print e.headers['www-authenticate']

You should add authorization headers. For more details have a look into: http://www.voidspace.org.uk/python/articles/authentication.shtml

您应该添加授权标头。有关更多详细信息，请查看：http: //www.voidspace.org.uk/python/articles/authentication.shtml

If you wish to send POST request , try it:

如果您想发送 POST 请求，请尝试：

import urllib
import urllib2
username = "username"
password = "password"
url = 'http://url.com/'
values = { 'username': username,'password': password }
data = urllib.urlencode(values)
req = urllib2.Request(url, data)
response = urllib2.urlopen(req)
result = response.read()
print result

Note:this is just an example of how to send POST request to URL.

注意：这只是如何向 URL 发送 POST 请求的示例。

I haven't played with python in awhile, but try this:

我有一段时间没有玩过 python，但试试这个：

urllib.urlopen("http://username:[email protected]/path")

You could use requestsinstead. The code is as simple as:

您可以改用请求。代码很简单：

import requests
url = 'https://updates.opendns.com/nic/update?hostname='
username = 'username'
password = 'password'
print(requests.get(url, auth=(username, password)).content)
