Python 带paramiko的Web2py用于ssh功能

我有一个通过web2py构建的表单，我需要使用它来验证和注册一台机器，并将其存储到数据库中。验证未通过。我总是收到这样的错误：“休斯顿似乎有一个机器名或超级密码的问题”。如果我在web2py环境之外运行paramiko脚本，它就可以正常工作。请帮忙

表格详情：

db.define_table('nsksystem',
  Field('nskmachinename', length=128, requires = IS_NOT_EMPTY(error_message='Machine Name cant be empty'), label = T('Machine Name')),
  Field('nskpassword', 'password', length=512,readable=False, label=T('Machine Password')),
  Field('confirmnskpassword', 'password', length=512,readable=False, label=T('Confirm Machine Password'))        )

控制器：default.py（用于在插入前验证表单插入）

控制器：default.py（用于插入数据库）

在建议之后，我删除了try/catch，下面是错误的回溯。我在Lib/ctypes下有wintypes.py。但是仍然无法理解为什么会出现导入错误

找到了解决方案。。。

我使用的是web2py的编译版本。当我使用源代码时，导入模块不再令人头痛。感谢Andrew Magee提醒大家…

我首先要去掉

try

/

之外的
，然后让异常消失，这样您就可以看到异常的实际情况。删除try/catch后发布错误日志。它给出了一个导入错误。但是wintypes模块在我的机器的ctypes下。
@auth.requires_login()
def machine():
form = SQLFORM(db.nsksystem)
if form.process(onvalidation=machinevalidate).accepted:
    response.flash = 'The machine is now registered to the user.'
elif form.errors:
    response.flash = 'Form has errors'
else:
    response.flash = 'Please register a machine to your ID'
return dict(form=form)
