错误类型错误：login_submit（）只需要1个参数（0给出）

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() takes exactly 1 argument (0 given)'

的代码是：

# -*- 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

From the docs，你输入的要求，而不是它作为参数：

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>"
