python - 如何解决 SuspiciousOperation : Invalid HTTP_HOST header error?

Question

我试图在 pythonanywhere 上部署我的 Django 应用程序.

从 apache 错误日志回溯:

2013-07-23 09:31:35,058 :Internal Server Error: /favicon.ico
Traceback (most recent call last):
  File "/usr/local/lib/python2.7/dist-packages/django/core/handlers/base.py", line 89, in get_response
    response = middleware_method(request)
  File "/usr/local/lib/python2.7/dist-packages/django/middleware/common.py", line 55, in process_request
    host = request.get_host()
  File "/usr/local/lib/python2.7/dist-packages/django/http/__init__.py", line 179, in get_host
    "Invalid HTTP_HOST header (you may need to set ALLOWED_HOSTS): %s" % host)
SuspiciousOperation: Invalid HTTP_HOST header (you may need to set ALLOWED_HOSTS): monty_singh.pythonanywhere.com

我尝试将 ['*'] 和 ['monty_singh.pythonanywhere.com'] 作为 ALLOWED_HOSTS 的值，但应用程序仍然不工作。无论我为 ALLOWED_HOSTS 设置什么值，我都会得到同样的错误。

当 Django 从 HTTP 请求中验证主机时，它会尝试将其与以下正则表达式进行匹配，您可以在 the source here 中找到该正则表达式。 :

host_validation_re = re.compile(r"^([a-z0-9.-]+|\[[a-f0-9]*:[a-f0-9:]+\])(:\d+)?$")

用户名中的下划线导致 Django 拒绝请求中的主机名。您可以创建一个 new PythonAnywhere account使用新的用户名或使用不同的网络框架。
