python如何實作實時檢測裝置_使用Django和Python 3檢測移動裝置

I am struggling to find an easy way to detect if the request comes from a mobile device in my Django views.

I am trying to implement something like this:

#views.py

def myfunction(request):

...

if request.mobile:

is_mobile = True

else:

is_mobile = False

context = {

... ,

'is_mobile': is_mobile,

}

return render(request, 'mytemplate.html', context)

And in mytemplate.html:

{% if is_mobile %}

show something

{% else %}

show something else

{% endif %}

Everywhere I checked (for instance here or here), minidetector is recommended. I have installed different versions: pip install minidetector, pip install minidetector2, as well as directly a couple of github repositories, but none of them are compatible with Python 3.

So here my question: Is there any version/fork of minidetector that is compatible with Python 3? If not, what are the alternatives?

Django User Agents package is compatible with Python 3.

Follow the installation instructions in the link provided above and then you can use it as follows:

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'

The usage in template is as follows:

{% if request.user_agent.is_mobile %}

Do stuff here...

{% endif %}

However, note that the middleware class has changed in Django 1.10. So if you are using Django 1.10 +, you will have to modify the middleware class definition in this Package as given in this GitHub issue tracker page.
