from wtforms import Form

定义一个类，目的用于获取html的form中的值
class RegistrationForm(Form):
    name = TextField('name', [validators.Length(min=4, max=25)])

这个是处理方法，目的是打印获取的值
class ReciveData(RequestHandler):
    def post(self):
        form = RegistrationForm()
        name = form.name.data
        self.write('Hello %s' %name)

总是报以下错误：

1.你这个form跟request没什么关联
2.tornado跟wtforms要集成一下先 不是拿过来就用的
tornado的参数不符合wtforms的需求 需要转换一下
