Python: requests, the HTTP client

The requests module of Python is one of the most common libraries to be used as an HTTP client.

httpbin.org is a nice service that you can use to try various HTTP requests.

In this articel I have collected a couple of the examples written using Python requests.

HTTP GET

examples/python/httpbin/get.py

import requests

res = requests.get('http://httpbin.org/get?name=Foo')
print(res.status_code)
print(res.reason)
print()

print("Headers:")
for key, value in res.headers.items():
    print(f"{key} {value}")

print()
#print(res.content)
for key, value in res.json().items():
    if key == "headers":
        continue
    print(f"{key} {value}")

The output will look like this:

examples/python/httpbin/get.out

200
OK

Headers:
Date Mon, 20 Apr 2020 12:15:08 GMT
Content-Type application/json
Content-Length 336
Connection keep-alive
Server gunicorn/19.9.0
Access-Control-Allow-Origin *
Access-Control-Allow-Credentials true

args {'name': 'Foo'}
origin 84.108.218.54
url http://httpbin.org/get?name=Foo

HTTP POST

examples/python/httpbin/post.py

import requests

res = requests.post('http://httpbin.org/post', data={"name": "Foo Bar"})
print(res.status_code)
print(res.reason)
print()

print("Headers:")
for key, value in res.headers.items():
    print(f"{key} {value}")

print()
#print(res.content)
for key, value in res.json().items():
    if key == "headers":
        continue
    print(f"{key} {value}")

The output will look like this:

examples/python/httpbin/post.out

200
OK

Headers:
Date Mon, 20 Apr 2020 12:15:02 GMT
Content-Type application/json
Content-Length 482
Connection keep-alive
Server gunicorn/19.9.0
Access-Control-Allow-Origin *
Access-Control-Allow-Credentials true

args {}
data 
files {}
form {'name': 'Foo Bar'}
json None
origin 84.108.218.54
url http://httpbin.org/post

Basic Authentication

examples/python/httpbin/basic_auth.py

import requests

# curl -i --user foo:bar https://httpbin.org/basic-auth/foo/bar

res = requests.get('http://httpbin.org/basic-auth/foo/bar', auth=('foo', 'bar'))
print(res.status_code)
print(res.reason)
print()
for key, value in res.headers.items():
    print(f"{key} {value}")

print()
print(res.content)
# for key, value in res.json().items():
#     print(f"{key} {value}")

What happens if you don't provide the credentials:

examples/python/httpbin/basic_auth_no_credentials.py

import requests

res = requests.get('http://httpbin.org/basic-auth/foo/bar')

print(res.status_code)
print(res.reason)
print()
for key, value in res.headers.items():
    print(f"{key} {value}")

What happens if you provide the wrong credentials?

examples/python/httpbin/basic_auth_wrong_credentials.py

import requests

res = requests.get('http://httpbin.org/basic-auth/foo/bar', auth=('foo', 'hello'))
print(res.status_code)
print(res.reason)
print()
for key, value in res.headers.items():
    print(f"{key} {value}")
