Python Mechanize浏览器：HTTP错误460

我正在尝试使用mechanize浏览器登录到一个站点，并收到一个HTTP 460错误，这似乎是一个虚构的错误，所以我不确定该如何处理它。代码如下：

# Browser
br = mechanize.Browser()

# Cookie Jar
cj = cookielib.LWPCookieJar()
br.set_cookiejar(cj)

# Browser options
br.set_handle_equiv(True)
br.set_handle_redirect(True)
br.set_handle_referer(True)
br.set_handle_robots(False)
br.set_handle_refresh(mechanize._http.HTTPRefreshProcessor(), max_time=1)
br.addheaders = [('User-agent', 'Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.1) Gecko/2008071615 Fedora/3.0.1-1.fc9 Firefox/3.0.1')]

br.open("https://foo.com/login")
br.select_form(nr=1)

br[br.form.controls[2].name] = "login@gmail.com" #I can't select the form or controls by name because they change every time
br[br.form.controls[3].name] = "mypassword"
br.method = "post"

response = br.submit()

以下是启用mechanize调试消息时出现的错误：

但是我认为我在这里没有正确使用br.click（）。

我确定该网站使用Javascript作为登录身份验证机制的一部分，因此Mechanize无法正确模拟浏览器。我切换到Selenium，它能够处理javascript并让我成功登录。

你可以问问维护你正在尝试的站点的人吗？正如您正确指出的，问题在于460不是一个公开定义的错误。这是4xx“Client error”系列中的一个错误，这意味着（假定开发人员出于这个原因选择了它）应用程序不喜欢您的请求。然而，这似乎是只有开发它的人才能回答的问题。可怕的是，我仅仅从发布的内容就可以认出这个网站。（你说得对，硒是个不错的选择）

response = br.form.click(br.form.controls[6].name)
