scrapy-fake-useragent-fix 0.1.1

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

scrapy-fake-useragent-fix
=====================

Random User-Agent middleware based on
`fake-useragent <https://pypi.python.org/pypi/fake-useragent>`__. It
picks up ``User-Agent`` strings based on `usage
statistics <http://www.w3schools.com/browsers/browsers_stats.asp>`__
from a `real world database <http://useragentstring.com/>`__.

Installation
-------------

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

pip install scrapy-fake-useragent-fix

Configuration
-------------

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

In Scrapy >=1.0:

.. code:: python

DOWNLOADER_MIDDLEWARES = {
'scrapy.downloadermiddlewares.useragent.UserAgentMiddleware': None,
'scrapy_fake_useragent.middleware.RandomUserAgentMiddleware': 400,
}

In Scrapy <1.0:

.. code:: python

DOWNLOADER_MIDDLEWARES = {
'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 ``desktop.chrome``, ``mobile.chrome``, only ``desktop``, ``mobile``, ``tablet`` are supported.

Usage with `scrapy-proxies`
---------------------------

To use with middlewares of random proxy such as `scrapy-proxies <https://github.com/aivarsk/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.
