from wtforms import Form, BooleanField, TextField, validators,PasswordField
class LoginForm(Form):
    username     = TextField('Username', [validators.Length(min=4, max=25)])
    password = PasswordField('Password')

当我像这样在 webapp(gae) 上使用 LoginForm 时：

def post(self):
    form=LoginForm(self.request)

但它显示错误：

Traceback (most recent call last):
  File "D:\Program Files\Google\google_appengine\google\appengine\ext\webapp\__init__.py", line 513, in __call__
    handler.post(*groups)
  File "D:\zjm_code\forum_blog_gae\main.py", line 189, in post
    form=LoginForm(self.request)
  File "D:\zjm_code\forum_blog_gae\wtforms\form.py", line 161, in __call__
    return type.__call__(cls, *args, **kwargs)
  File "D:\zjm_code\forum_blog_gae\wtforms\form.py", line 214, in __init__
    self.process(formdata, obj, **kwargs)
  File "D:\zjm_code\forum_blog_gae\wtforms\form.py", line 85, in process
    raise TypeError("formdata should be a multidict-type wrapper that supports the 'getlist' method")
TypeError: formdata should be a multidict-type wrapper that supports the 'getlist' method

如何让它运行

谢谢

您应该传入self.request.form（实际的表单字段，而不是整个请求）
