Django 无效的 HTTP_HOST 标头：'\x80\xc7\xda\x9e'

Question

我收到了托管在 Digital ocean 上的 Django 1.7 应用程序的错误。

无效的 HTTP_HOST 标头：“\x80\xc7\xda\x9e”。根据 RFC 1034/1035，提供的域名无效。

Request repr():
<WSGIRequest
path:/xmlrpc.php,
GET:<QueryDict: {}>,
POST:<QueryDict: {}>,
COOKIES:{},
META:{'HTTP_CONNECTION': 'close',
 'HTTP_HOST': '\x80\xc7\xda\x9e',
 'HTTP_USER_AGENT': 'Mozilla/5.0 (Windows NT x.y; Win64; x64;  rv:10.0)Gecko/20100101 Firefox/10.0',

 'REMOTE_ADDR': '181.214.92.100',
 'REMOTE_PORT': '80',

 'SERVER_PORT': '80',
 'SERVER_PROTOCOL': 'HTTP/1.0',

 'wsgi.multiprocess': False,
 'wsgi.multithread': False,
 'wsgi.run_once': False,

 'wsgi.version': (1, 0)}>

我已在基础文件中设置了 ALLOWED_HOSTS=['*']。此错误的原因是什么？我该如何解决？
