HTTP请求对象不响应 [英] HTTP Request Object does not respond

问题描述

我正在Django登录表单。
当我点击登录提交按钮时，它给出错误

ValueError at / registration /
视图注册。 .login没有返回一个HttpResponse对象。

视图文件是

从django.shortcuts导入render
从registration.models import注册
从django.http导入HttpResponse
def login（请求）：
如果request.method =='POST'：
user = authenticate（username = request.POST ['username']，password = request.POST ['password']）
如果用户不是没有：
如果user.is_active：
登录（请求，用户）
＃success
返回HttpResponseRedirect（'sucess'）
else：
＃disabled account
return direct_to_template（request，'inactive_account.html'）
else：
＃无效登录
返回direct_to_template（请求， 'invalid_login.html'

def logout（request）
logout（request）
return direct_to_template（request，'logged_out.html'）

和login.html文件是

 < H3>登录< / H3> 
< form action =/ login /method =postaccept-charset =utf-8> 
< label for =username>用户名： - < / label>< input type =textname =usernamevalue =id =username/>< BR> 
< label for =password>密码： - < / label>< input type =passwordname =passwordvalue =id =password/> 
< p>< input type =submitvalue =Login→>< / p> 
< / form> 
  

解决方案

您的登录视图将返回一个POST请求的HttpResponse只有（在表单提交）。当您将浏览器寻址到登录页面时，它会产生一个GET请求，这不是在您的视图中处理

我建议您阅读有关用户验证的更多信息：一个href =https://docs.djangoproject.com/en/dev/topics/auth/#how-to-log-a-user-in =nofollow> doc 。

如上所述，使用 render 或 render_to_response from django.shortcuts

I am making a login form in Django. When I am click on login submit button , It gives an error of

ValueError at /registration/ The view registration.views.login didn't return an HttpResponse object.

The view file is

from django.template import  loader
from django.shortcuts import render
from registration.models import Registration
from django.http import HttpResponse
def login(request):
  if request.method == 'POST':
    user = authenticate(username=request.POST['username'], password=request.POST['password'])
    if user is not None:
      if user.is_active:
        login(request, user)
        # success
        return HttpResponseRedirect('sucess')
      else:
        # disabled account
        return direct_to_template(request, 'inactive_account.html')
    else:
      # invalid login
      return direct_to_template(request, 'invalid_login.html')

def logout(request):
  logout(request)
  return direct_to_template(request, 'logged_out.html')

and login.html file is

<h3>Login</h3>
<form action="/login/" method="post" accept-charset="utf-8">
<label for="username">Username:--</label><input type="text" name="username" value="" id="username" /><br>
<label for="password">Password:-- </label><input type="password" name="password" value="" id="password" />
<p><input type="submit" value="Login →"></p>
</form>

解决方案

Your login view will return a HttpResponse for a POST request only (on form submit). When you address your browser to login page, it makes a GET request, which is not handled in your view

I`ll recomend you to read more about user athentication: doc.

And as mentioned, use render or render_to_response functions from django.shortcuts
