我正在尝试用python和webscraping自动化一些任务。但首先，我需要登录一个网站，我有一个帐户。你知道吗

我见过几个关于堆栈溢出的例子，但是由于某些原因，这个网站不允许我使用请求登录。有人能告诉我我做错了什么吗？你知道吗

网页： https://www.americanbulls.com/Signin.aspx?lang=en

表单变量： ctl00$main内容$uEmail ctl00$MainContent$uPassword

是因为变量名中有“$”吗？你知道吗

任何帮助都将不胜感激。你知道吗

你的代码看起来很棒。脚本似乎失败了，因为您没有提交浏览器正常提交的所有内容。您可以尝试沿着当前的路径继续，提交所有额外的表单数据，并且希望您不必费心添加CSRF令牌（CSRF令牌是一个随机生成的字符串，您需要将其发送回），或者您可以按照Sidharth Shah suggested的操作并使用Selenium。你知道吗

Selenium有一个Firefox扩展，它允许您开始记录鼠标和键盘的操作，然后在完成后，您可以用Python导出结果。Python代码将依赖于Selenium库和Selenium Chrome/Firefox/IE驱动程序。运行Python代码时，将打开一个新的浏览器窗口，由selenium驱动程序和Python代码控制。这很酷，你基本上是在编写控制浏览器窗口的Python代码。你将不得不修改Python代码，Firefox扩展会给你一点时间来读取页面中的所有数据，并在你登录后开始处理这些数据，但是打开浏览器窗口、导航到登录页面、填写登录凭据和提交表单的代码，登录后导航到其他页面都将为您编写。你知道吗
