Question

很抱歉，如果这是一个菜鸟问题。我正在为Django应用程序创建一个登录表单，但是我无法让它运行起来。 request.POST.get（）不返回任何内容，因此身份验证始终失败。我错过了一些明显的东西吗？

的login.html：

{% extends "base.html" %}

{% block content%}

<h2>Welcome! Please login to continue.</h2> <br>
<form action="{% url 'account:authenticate' %}" method="post">
    {% csrf_token %}
    <div >
        <label for='username'> Username: </label>
        <input type='text' name='Username' id='username'> <br><br>
        <label for='password'>Password:  </label>
        <input type='password' name='Password' id='password'><br><br>
        <input type='submit' value='Login'>
    </div>
</form>

views.py的相关部分：

from django.shortcuts import render, get_object_or_404
from datetime import datetime   
from django.http import HttpResponse, Http404, HttpResponseRedirect
from django.template import loader
from random import randrange
from django.contrib.auth import authenticate

def login(request):
    return render (request, 'login.html')

def authenticate(request):
    usern = request.POST.get('username', '')
    passw = request.POST.get('password', '')
    user = authenticate(username = usern, password = passw)      
    if user is not None:
        authenticate.login(request, user)
        return HttpResponseRedirect('/voters/instructions')
    else:
        return HttpResponseRedirect('/account/loginfail')

def loginfail(request):
    return render (request, 'loginfail.html')

我正在使用Django 1.10。谢谢！

检查表单输入字段中的名称是否区分大小写。在Django做这个

 usern = request.POST.get('Username', '')
 passw = request.POST.get('Password', '')

或以html格式将它们设为小写输入名称字段

Django Form request.POST.get（）总是返回空
