始终获得此AssertionError：302！= 200：无法检索内容：响应代码为302（预期为200）

Question

我在django中是非常陌生的人，目前正在学习一个教程，我正在尝试测试用户。所以我设置了test_admin.py。我得到一个AssertionError 302！= 200。

下面是我的test_admin.py

from django.test import TestCase,Client
from django.contrib.auth import get_user_model
from django.urls import reverse


class AdminSiteTests(TestCase):

    def setUp(self):
        self.client = Client()
        self.admin_user = get_user_model().objects.create_superuser(
            email='[email protected]',
            password='092100027h'
        )
        self.client.force_login(self.admin_user)
        self.user = get_user_model().objects.create_user(
            email='[email protected]',
            password='092100027h',
            name='Test User Full Name'
        )

    def test_users_listed(self):
        """
        Test that users are listed on user page
        """
        url = reverse('admin:core_user_changelist')
        res = self.client.get(url)

        self.assertContains(res, self.user.name)
        self.assertContains(res, self.user.email)

这是我的admin.py

from django.contrib import admin
from django.contrib.auth.admin import UserAdmin as BaseUserAdmin

from . import models

class UserAdmin(BaseUserAdmin):
    ordering = ['id']
    list_display = ['email', 'name']


admin.site.register(models.User, UserAdmin)

这是我的错误

该问题可能与APPEND_SLASH Django设置有关。默认情况下，其True。因此，请检查您的网址文件，并确保该网址以斜杠/结尾（例如articles/<int:year>/），否则Django将找不到该网址，并且会自动添加斜杠并将您重定向到新的网址，并且您会收到302状态代码作为重定向。
