如何在Django中检测浏览器类型？

Question

如何检测客户端使用的浏览器类型.我有一个问题,我必须要求人们使用不同的浏览器(Firefox)而不是IE.我怎样才能获得这些信息.

我知道http请求有这个信息(Header).我如何从Django框架中的view.py获取navigator.appName？

Answer 1

您可以从请求对象中提取该信息,如下所示:

request.META['HTTP_USER_AGENT']

Answer 2

有多种方法可以完成这项工作.

最简单的方法是@digitaldreamer推荐的.那就是你可以提出元请求HTTP_USER_AGENT.

request.META['HTTP_USER_AGENT']

但我还建议你看一下Django用户代理库.

用pip安装它

pip install pyyaml ua-parser user-agents
pip install django-user-agents

并配置settings.py:

MIDDLEWARE_CLASSES = (
    # other middlewares...
    'django_user_agents.middleware.UserAgentMiddleware',
)

INSTALLED_APPS = (
    # Other apps...
    'django_user_agents',
)

# Cache backend is optional, but recommended to speed up user agent parsing
CACHES = {
    'default': {
        'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
        'LOCATION': '127.0.0.1:11211',
    }
}

# Name of cache backend to cache user agents. If it not specified default
# cache alias will be used. Set to `None` to disable caching.
USER_AGENTS_CACHE = 'default'

用法非常简单.

user_agent现在将一个属性添加到请求中,您可以在views.py中使用该属性:

def my_view(request):

# Let's assume that the visitor uses an iPhone...
request.user_agent.is_mobile # returns True
request.user_agent.is_tablet # returns False
request.user_agent.is_touch_capable # returns True
request.user_agent.is_pc # returns False
request.user_agent.is_bot # returns False

# Accessing user agent's browser attributes
request.user_agent.browser  # returns Browser(family=u'Mobile Safari', version=(5, 1), version_string='5.1')
request.user_agent.browser.family  # returns 'Mobile Safari'
request.user_agent.browser.version  # returns (5, 1)
request.user_agent.browser.version_string   # returns '5.1'

# Operating System properties
request.user_agent.os  # returns OperatingSystem(family=u'iOS', version=(5, 1), version_string='5.1')
request.user_agent.os.family  # returns 'iOS'
request.user_agent.os.version  # returns (5, 1)
request.user_agent.os.version_string  # returns '5.1'

# Device properties
request.user_agent.device  # returns Device(family='iPhone')
request.user_agent.device.family  # returns 'iPhone'

Answer 3

您可以查看"用户代理字符串"并解析值.

这是相关的文档,特别是关于(HTTP_USER_AGENT):
