python - Python/Mechanize 中的 Http 错误 405/500(使用 mechanize 自动登录一个网站)

Question

这是我想使用 python/mechanize 自动登录的网站地址:

http://www.autohome.com.cn/tools/hometoplogin.html

这是我的代码:

br = Browser()
login_url = 'http://www.autohome.com.cn/tools/hometoplogin.html'
cj = cookielib.LWPCookieJar()
br.set_cookiejar(cj)
br.open(login_url)
br.select_form(nr = 0)
br['name'] = username
br['pwd'] = password
print br.submit().read()

但是代码抛出 Http 错误 500:

File "build\bdist.win32\egg\mechanize\_mechanize.py", line 541, in submit
File "build\bdist.win32\egg\mechanize\_mechanize.py", line 203, in open
File "build\bdist.win32\egg\mechanize\_mechanize.py", line 255, in _mech_open
mechanize._response.httperror_seek_wrapper: HTTP Error 500: Internal Server Error

有时它会抛出 Http Error 405:

HTTP Error 405: Method Not Allowed

现在我很困惑...请帮助...

现在我已经修复了我的 python 代码，如下所示

username = 'staryin'
password = 'zxy1985'
login_url = 'http://www.autohome.com.cn/tools/hometoplogin.html'
br = Browser()
cj = cookielib.LWPCookieJar()
br.set_cookiejar(cj)
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(login_url)
br.select_form(nr = 0)
br['name'] = username
br['pwd'] = password
br.form.action = login_url
br.submit().read()

它还会抛出如下所示的 http 错误 405

File "build\bdist.win32\egg\mechanize\_mechanize.py", line 541, in submit
File "build\bdist.win32\egg\mechanize\_mechanize.py", line 203, in open
File "build\bdist.win32\egg\mechanize\_mechanize.py", line 255, in _mech_open
mechanize._response.httperror_seek_wrapper: HTTP Error 405: Method Not Allowed

谁能帮我解决这个问题？非常感谢。
