What are Requests

Python HTTP library. Python has a library called urllib2, but as the official website explains Requests is an Apache2 Licensed HTTP library, written in Python, for human beings., It is easy for humans to code.

How to use

Library import

import requests


There are one-to-one correspondence methods for various HTTP methods.

#Get header

Parameter assignment

Add params = to the argument of the request method with hash of the parameter to be added.

>>> payload = {'key1': 'value1', 'key2': 'value2'}
>>> r = requests.get('URL', params=payload)

Custom header

When specifying a UA in a GET request

>>> headers = {'User-Agent': 'Sample Header'}
>>> requests.get('URL', headers=headers)

When adding data to HTTP headers with a POST request

>>> payload = {'send': 'data'}
>>>'URL', data=json.dumps(payload))

Contents of the response


Get the returned response body in text format. The request is automatically decoded into unicode.

>>> r = requests.get('')
>>> r.text
'<!DOCTYPE html>\n<html lang="en-US" class="dev-desktop uni-purple-border  bkt901 https  uni-dark-purple sasb-space" style="">\n<!-- m2 template  -->\n<head>\n    <meta http-equiv="Content-Type" ...


Get encoding information


Get the response body in binary format.

>>> import requests
>>> r = requests.get('')
>>> r.content

Processing for each response


Use PIL's Image module.

>>> from PIL import Image
>>> from StringIO import StringIO
>>> r = requests.get('')
>>> i =


>>> requests.get('').json()
{'@context': {'foaf': '', 'prism': '', 'rdfs': '', 'owl': ' ...

    """ requests sample that use qiita search api
    >>> 'title' in sample('python')
    >>> 'totle' in sample('python')
    q = {'q':  query}
    r = requests.get('', params=q)
    return list(r.json()[0].keys())
