Python请求ConnectionError

Question

我正试图登录到website。随着下面的一段代码：

import requests 

values = {'password': 'somepass', 'username': 'someusername'} 
login_url = "http://voobly.com/login" 

session_requests = requests.session() 
r = session_requests.post(login_url, data=values, 
          headers=dict(referer=login_url)) 

这是登录到网站的形式。

<form action="/login/auth" method="post"> 
    <label for="username">Username: </label> 
    <input type="text" name="username" id="username" class="inputfield" value=""> 
    <label for="password">Password: </label> 
    <input type="password" name="password" id="password" class="inputfield"> 
    <input type="submit" value="Login" class="login-button"> 
</form> 

好吧，当我运行代码，我得到这个错误：

HTTPConnectionPool(host='www.voobly.com', port=80): Max retries exceeded with url: /login 
(Caused by NewConnectionError('<requests.packages.urllib3.connection.HTTPConnection object at 0x7f7cca037be0>: 
Failed to establish a new connection: [Errno -2] Name or service not known',)) 

我怎样才能解决这个问题？我可以在浏览器中登录，但无法通过Python代码登录。

您发送POST请求发送到错误的URL，它应该是http://www.voobly.com/login/auth：

import requests 

values = {'password': 'somepass', 'username': 'someusername'} 
login_url = "http://www.voobly.com/login/auth" 
headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; WOW64)', 
      ... # more... 
      'Referer': 'http://www.voobly.com/login'} 

session_requests = requests.session() 
r = session_requests.post(login_url, data=values, 
          headers=headers)
