Fake Http Header

fake-http-header is a python package that you can use to generate random request fields for a http header. The generated header fields look like they might come from a real internet browser. It is accomplished by mapping browsers to default values and emulating real user behaviour. You can utilize this package, for instance, to write crawlers or testing web applications.

Installation

The easiest way to install this package is using pip. In case you have pip on your system, just type the following command into your terminal prompt:

pip install fake-http-header

Quick Start

Generating a random http header is quite straight forward. Just import the package and call the construcor method for the FakeHttpHeader class without any parameters.

Example:

from fake_http_header import FakeHttpHeader

fake_header = FakeHttpHeader()
print(fake_header)

Output:

FakeHttpHeader(user_agent='Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/96.0.4664.55 Safari/537.36 Edg/96.0.1054.43', accept_language='en-GB',  accept_encoding='identit,b',  accept='text/html, application/xhtml+xml, image/jxr, */*', referer='http://www.intute.ac.uk')

As you can see, the generated header contains an Accept-Language field, which states that the client prefers british english (accept_language='en-GB'). To make this header look more plausible, the referrer site is thereby generated from a pool of .uk domains.

It is also possible to specify of which top level domain the referer site should be. In that case, a fitting Accept-Language field will be generated.

Example:

fake_header = FakeHttpHeader(domain_code = 'de')
print(fake_header)

Output:

FakeHttpHeader(user_agent='Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/96.0.4664.45 Safari/537.36', accept_language='de', accept_encoding='deflat,b,compres', accept='text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8', referer='http://www.netluchs.de')

When working with other python libraries like requests, it is necessary to transform our fake_header object into a dictionary representation that is compatible with the request library. For this purpose, the FakeHttpHeader class provides the as_header_dict method.

import requests

my_url = https://github.com/
fake_header_dict = fake_header.as_header_dict()

r = requests.get(my_url, headers=fake_header_dict)

Future ideas

Add weights to certain header fields (e.g. Accept: text/html, application/xhtml+xml, application/xml;q=0.9)
