Use a random User-Agent provided by fake-useragent for every request

Project description


Random User-Agent middleware based on
`fake-useragent <>`__. It
picks up ``User-Agent`` strings based on `usage
statistics <>`__
from a `real world database <>`__.


The simplest way is to install it via `pip`:

pip install scrapy-fake-useragent-fix


Turn off the built-in ``UserAgentMiddleware`` and add

In Scrapy >=1.0:

.. code:: python

'scrapy.downloadermiddlewares.useragent.UserAgentMiddleware': None,
'scrapy_fake_useragent.middleware.RandomUserAgentMiddleware': 400,

In Scrapy <1.0:

.. code:: python

'scrapy.contrib.downloadermiddleware.useragent.UserAgentMiddleware': None,
'scrapy_fake_useragent.middleware.RandomUserAgentMiddleware': 400,

Configuring User-Agent type

There's a configuration parameter ``RANDOM_UA_TYPE`` defaulting to ``random`` which is passed verbatim to the fake-user-agent to random choose user agents. ``random``, ``chrome``, ``firefox``, ``safari``, ``internetexplorer`` are supported. If you want to choose from a specific device type, you can use a device prefix before browse type, such as ````, ````, only ``desktop``, ``mobile``, ``tablet`` are supported.

Usage with `scrapy-proxies`

To use with middlewares of random proxy such as `scrapy-proxies <>`_, you need:

1. set ``RANDOM_UA_PER_PROXY`` to True to allow switch per proxy

2. set priority of ``RandomUserAgentMiddleware`` to be greater than ``scrapy-proxies``, so that proxy is set before handle UA

Configuring Fake-UserAgent fallback

There's a configuration parameter ``FAKEUSERAGENT_FALLBACK`` defaulting to
``None``. You can set it to a string value, for example ``Mozilla`` or
``Your favorite browser``, this configuration can completely disable any
annoying exception.
