我正在尝试使用 Python 2.7.5 和mechanize 库创建一个程序，将我登录到我在bing.com上的 Microsoft 帐户。首先，我创建了这个程序来打印该网页上的表单名称，以便在以后的代码中引用它们。我当前的代码是这样的（对长 URL 感到抱歉）：

import mechanize
br = mechanize.Browser()
br.set_handle_robots(False)
br.addheaders = [('User-agent','Firefox')]

br.open("https://login.live.com/ppsecure/post.srf?wa=wsignin1.0&rpsnv=11&ct=1375231095&rver=6.0.5286.0&wp=MBI&wreply=http:<%2F%2Fwww.bing.com%2FPassport.aspx%3Frequrl%3Dhttp%253a%252f%252fwww.bing.com%252f&lc=1033&id=264960&bk=1375231423")
print(br.title)

forms_printed = 0
for form in br.forms():
    print form
    forms_printed += 1
if forms_printed == 0:
    print "No forms to print!"

尽管当我在 Firefox 中访问网页时，我看到了用户名和密码表单，但当我运行此代码时，结果始终是“没有要打印的表单！” 我在这里使用了 mechanize 错误，还是网站故意阻止我找到这些表格？非常感谢任何提示和/或建议。

如果您尝试阅读您收到的 HTML，您将看到该网页需要 javascript。

例子：

import mechanize
br = mechanize.Browser()
br.set_handle_robots(False)
br.addheaders = [('User-agent','Firefox')]

page = br.open("https://login.live.com/ppsecure/post.srf?wa=wsignin1.0&rpsnv=11&ct=1375231095&rver=6.0.5286.0&wp=MBI&wreply=http:<%2F%2Fwww.bing.com%2FPassport.aspx%3Frequrl%3Dhttp%253a%252f%252fwww.bing.com%252f&lc=1033&id=264960&bk=1375231423")
print page.read()
print(br.title)

forms_printed = 0
for form in br.forms():
    print form
    forms_printed += 1
if forms_printed == 0:
    print "No forms to print!"

输出：
