使用python请求登录网站 [英] Login to a website using python requests
问题描述
我在通过python脚本登录网站时遇到了一些困难,以便稍后在连接后可以从中检索数据. 我认为,HTML页面中具有期望用户名和密码的形式的部分如下:
I encounter some difficulties to log on a website from a python script, in order to retrieve data from it later on, once I will be connected. I think that the part of the HTML page with the form expecting username and password is the following :
<div class="contentLogin">
<form action="/login/loginSubmit" method="post" class="memberLogin">
<table cellpadding="0" cellspacing="0" border="0" >
<tr>
<td><label class="color2">Déjà membre</label></td>
<td> </td>
<td><input type="text" value="pseudo" class="input" name="login" id="login" /></td>
<td><input type="password" value="pass" class="input" name="pass" id="pass" /></td>
<td><input type="submit" value="ok" class="color2 loginSubmit" /></td>
</tr>
<tr>
<td colspan="3"></td>
<td colspan="2" >
<a href="#" class="forgotPassword color2" id="forgotPassword">Mot de passe oublié ?</a>
</td>
</tr>
</table>
</form> </div>
我想使用python语言的请求"模块来执行POST请求,该请求会将我连接到该站点. 我的代码已经包含以下命令:
I would like to use the "requests" module of python langage, to do the POST request that will connect me to the site. My code already contains the following commands :
import requests
pars = {'login': 'dva2tlse', 'pass': 'VeryStrong', 'action': 'Idunno'}
resp = requests.post("http://www.example.com", params=pars)
但是它似乎不起作用,因为我什至不知道应该在POST请求中指示WHICH动作. (我什至不知道如何使用它,因为我从未做过) 谢谢您帮助我使所有工作正常进行, 大卫
But it seems not to work, because I even do not know WHICH action should be indicated within th POST request. (I do not even know how exactly to use it, since I never done it) Thank' you to help me make all that work correctly, David
推荐答案
更改requests.post
中的url值以匹配<form action>
属性中给出的值.
Change the url value in requests.post
to match the one given in <form action>
attribute.
此外,删除pars
词典中的action
键.
Also, remove the action
key in your pars
dictionary.
pars = { 'login': 'dva2tlse', 'pass': 'VeryStrong' }
resp = requests.post("http://example.com/login/loginSubmit", params=pars)
如果您想保留登录状态以进行进一步的页面调用,可以使用requests.Session()
If you want to keep your login state for further page calls, you can use requests.Session()
s = requests.Session()
pars = { 'login': 'dva2tlse', 'pass': 'VeryStrong' }
resp = s.post("http://example.com/login/loginSubmit", params=pars)
只要继续使用s
,您就可以保持登录状态.
As long as you keep using s
, you will stay logged in.
