Question

我已使用以下代码在Django中实现了用户登录;

在我的urls.py中;

.
.
.
    url(r'^login/', UserLogin.as_view(), name='userlogin'),
.
.

在我的views.py;

中

.
.
from django.contrib.auth.forms import AuthenticationForm    
.
.
.
class UserLogin(FormView):
    form_class = AuthenticationForm
    template_name = "auth/login.html"

    def get_success_url(self):
        return reverse('userhome', kwargs={'pk': self.request.user.id})
.
.
.

我的auth / login.html是;

{% block head %}
  <title>Open Radio | Login</title>
{% endblock %}

{% block body %}
  <header>
    <h1>Open Radio</h1>
    <h2>Login Page</h2>
  </header>

  <section>
    {% if form.errors %}
      <p>Your username and password didn't match, please try again.  </p>
    {% endif %}

    <form method="post" action=".">
      {% csrf_token %}
      <p>
        <label for="id_username">Username:</label>
        {{ form.username }}
      </p>
      <p>
        <label for="id_password">Password:</label>
        {{ form.password }}
      </p>
      {% if next %}
        <input type="hidden" name="next" value="{{ next }}" />
      {% endif %}
      <input type="submit" value="login" />
    </form>
  </section>
{% endblock %}

它有效并且确实将我带到了我定义的用户主页。

但是当我运行以下测试时;

class TestLoginPage(TestCase):
    .
    .
    .     

    def test_page_logs_in(self):
        """
        Tests if the login page actually logs a user in
        """
        username = "someusername"
        password = "somepassword"
        user = User(username=username,
                    password=password)
        user.save()
        response = self.client.post(reverse("userlogin"),
                                    {"username":username,
                                     "password":password},
                                    follow=True)
        assert response.context["user"].is_authenticated()

我得到以下失败;

self = <stationrunner.tests.TestLoginPage testMethod=test_page_logs_in>

    def test_page_logs_in(self):
        """
        Tests if the login page actually logs a user in
        """
        username = "someusername"
        password = "somepassword"
        user = User(username=username,
                    password=password)
        user.save()
        response = self.client.post(reverse("userlogin"),
                                    {"username":username,
                                     "password":password},
                                    follow=True)
>       assert response.context["user"].is_authenticated()
E       AssertionError: assert <bound method   AnonymousUser.is_authenticated of   <django.contrib.auth.models.AnonymousUser object at 0x7f54b5433a50>>()
E        +  where <bound method AnonymousUser.is_authenticated of  <django.contrib.auth.models.AnonymousUser object at 0x7f54b5433a50>> =   <SimpleLazyObject: <django.contrib.auth.models.AnonymousUser object at   0x7f54b5433a50>>.is_authenticated

任何人都可以解释为什么会发生这种情况

登录不会成功，因为Django希望密码是一个哈希，但你已经用纯文本保存了它。这样做：

user = User.objects.create_user(username=username, password=password)

修改

你的问题非常简单，你的UserLogin视图，尽管名称，从来没有实际登录用户.AuthenticationForm执行其名称暗示，即认证，但后来没有做任何事情经过身份验证的用户将其登录。

至少，您需要在视图中的某个地方拨打login();但是，在这里使用您自己的自定义视图而不是内置的django.contrib.auth.views.login视图似乎不是一个很好的理由。

Django测试客户端在登录后返回匿名用户
