Python請求ConnectionError

Question

我正試圖登錄到website。隨着下面的一段代碼：

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)) 

這是登錄到網站的形式。

<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，當我運行代碼，我得到這個錯誤：

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',)) 

我怎樣才能解決這個問題？我可以在瀏覽器中登錄，但無法通過Python代碼登錄。

您發送POST請求發送到錯誤的URL，它應該是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)
