python - 错误类型错误：login_submit() 正好采用 1 个参数（给定 0）

Question

我使用 Bottle 框架制作了一个简单的程序。我收到此错误：

'TypeError: login_submit() 只需要 1 个参数（给定 0）'

代码是：

# -*- coding: cp1252 -*-
import codecs
from bottle import route, run, template


@route('/login')
def login_form():
    return '''<form method="POST" action="/login">
            <input name="name" type="text" />
            <input name="password" type="password" />
            <input type="submit" />
          </form>'''

@route('/login', method='POST')
def login_submit(request):
  name = request.forms.get('name')
  password = request.forms.get('password')
  if check_login(name, password):
    return "<p>Your login was correct</p>"
  else:
    return "<p>Login failed</p>"

run(host='localhost', port=8080)

Answer 1

从 docs导入请求，而不是将其作为参数：

from bottle import post, request

...

@route('/login', method='POST') # or @post('/login')
def login_submit():
  name = request.forms.get('name')
  password = request.forms.get('password')
  if check_login(name, password):
    return "<p>Your login was correct</p>"
  else:
    return "<p>Login failed</p>"
