Django Invalid HTTP_HOST header: 'testserver'. You may need to add u'testserver' to ALLOWED_HOSTS
提问by Yuiry Kozlenko
I started learning Django, I'm in the middle of implementing "Test a view" functionality. When I use test Clientin the shell, the exception has occurred as follows.
我开始学习 Django，我正在实现“测试视图”功能。当我在shell中使用test Client时，出现了如下异常。
Invalid HTTP_HOST header: 'testserver'. You may need to add u'testserver' to ALLOWED_HOSTS.
无效的 HTTP_HOST 标头：'testserver'。您可能需要将 u'testserver' 添加到 ALLOWED_HOSTS。
I run the command in the shell as follows.
我在 shell 中运行命令如下。
>>> from django.test.utils import setup_test_environment
>>> setup_test_environment()
>>> from django.test import Client
>>> client = Client()
>>> response = client.get('/')
>>> response.status_code
400
In the tutorial, 404 should be appeared, but I get 400. When I continue running the command as follows, same exception has occurred.
在教程中，应该出现404，但我得到400。当我继续运行如下命令时，发生了同样的异常。
>>> response = client.get(reverse('polls:index'))
>>> response.status_code
400
but the result must be 200.I guess I should declare ALLOWED_HOSTSin the settings.py, but how can I? I run the server on localhost using $python manage.py runserver.
但结果必须是 200。我想我应该在settings.py 中声明ALLOWED_HOSTS，但我该怎么做？我使用$python manage.py runserver在本地主机上运行服务器。
I wanna know the reason and solution.
我想知道原因和解决方案。
Here is settings.py as follows.

You should edit it like that:
你应该像这样编辑它：
ALLOWED_HOSTS = [ '127.0.0.1', 'localhost', 'testserver', ]
ALLOWED_HOSTS = [ '127.0.0.1', 'localhost', 'testserver', ]

You can try for testing purpose
您可以尝试用于测试目的
ALLOWED_HOSTS = ['*']

settings.py is in read-only mode
settings.py 处于只读模式
ALLOWED_HOSTS = ['127.0.0.1', 'localhost']
this is how to save it

Apart from the correct answers, there is an important check which you need to keep in mind. Setting ALLOWED_HOSTS with a single valued tuple will still give you same error, for example if you set it this way:
除了正确的答案，还有一个重要的检查你需要记住。使用单值元组设置 ALLOWED_HOSTS 仍然会给你同样的错误，例如，如果你这样设置：
ALLOWED_HOSTS=('testserver')
It does not work, because you may wanted to make this a tuple but ACTUALLY it is a string in Python, yes thats strange but true! you can read more about tuples here: tuples.
它不起作用，因为您可能想让它成为一个元组，但实际上它是 Python 中的一个字符串，是的，这很奇怪，但确实如此！您可以在此处阅读有关元组的更多信息：tuples。
If you want to make it a tuple, you need to add a comma like this:
如果你想把它变成一个元组，你需要像这样添加一个逗号：
ALLOWED_HOSTS=('testserver',)
This works as expected.
这按预期工作。
