无效响应在 /qr/ 协议错误：<，头部

正在尝试将QR代码身份验证在我的项目中实现。因此，我使用了" Django-Qrauth"模块。我遵循https://github.com/aruseni/django-qrauth中提到的每个步骤，但是正在遇到以下错误。

------------------------------------------------------------------------------------------------------------

#settings.py
AUTH_QR_CODE_EXPIRATION_TIME = 600 # Ten minutes
AUTH_QR_CODE_REDIS_KWARGS = {
    "host": "192.168.17.1",
    "port": 1111,
    "db": 0,
}
#urls.py
    urlpatterns = patterns('',
        url(r'^admin/', include(admin.site.urls)),
        url(r'^qr/', include('qrauth.urls')),
    )

任何人都可以告诉发生什么。

似乎您已经为Django服务器和Redis服务器配置了相同的端口。

Django服务器于192.168.17.1端口1111在调试输出中的Request URL: http://192.168.17.1:1111/qr/消息证明。另外，settings.py中的Redis服务器配置指定相同的主机名和端口：

AUTH_QR_CODE_REDIS_KWARGS = {
    "host": "192.168.17.1",
    "port": 1111,
    "db": 0,
}

因此，Django的Redis客户端正在连接到Django服务器，发送redis请求，然后接收以<head>标签开头的HTML响应。这是可以预期的，因为它是已联系的Django服务器。

您需要更改REDIS设置，以将端口设置为Redis服务器正在侦听的端口。默认情况下，这是端口6379，但是您可以在Redis配置文件中检查。
