Question

使用python登录到Web门户时出现问题。我尝试使用其他帖子中的建议

How can I login to a website with Python?

我已经尝试过使用斜纹布（由于我正在运行Python 3.6而无法安装）-如果有人对如何安装斜纹布有建议，请告知

我也尝试使用：

import requests
url = 'http://example.com/userinfo.php'
values = {'username': 'user',
          'password': 'pass'}

r = requests.post(url, data=values)
print(r.content)

没有运气。

登录页面包含以下html

<form id="form" method="post" action="/" style="padding-left:20px;" class="form-horizontal">
                    <div class="control-group">
                        <label class="control-label" for="username">User Name:</label>
                        <div class="controls">
                            <input id="username" type="text" placeholder="User Name" autocomplete="off" autocorrect="off" autocapitalize="off">

                    <div class="control-group">
                        <label class="control-label" for="ba_password2">Password:</label>

                            <img src="/images/warn.png"/>
                            Caps lock is on.
                        </div>
                    </div>
                </form>

我希望有人能提供帮助。谢谢

考虑使用webbot之类的库，该库甚至可以处理动态更改的网页元素的类和ID。

Answer 2

使用Python代码必须如下所示：

#Open Firefox browser
driver = webdriver.Firefox()
#Enter email
elem = driver.find_element_by_id("username")
elem.clear()
elem.send_keys("email")
#Enter password
elem = driver.find_element_by_id("ba_password2")
elem.clear()
elem.send_keys("pass")
#Click button
elem = driver.find_element_by_id("ba_loginbut")
elem.click()
