What is HTTP communication?

There are four major HTTP methods: GET, POST, PUT, and DELETE.

These four are often used when developing web services and applications using APIs.

In order, they are “data acquisition, creation, update, and deletion.

Now, let’s look at requests, which is an HTTP method in Python.

How to use requests

Installation is performed as follows.

pip install requests

The URL this time is “http://httpbin.org”.

import requests

payload = {'key1': 'value1', 'key2': 'value2'}

#(GET) 
r = requests.get('http://httpbin.org/get', params=payload)
#(POST)
 r = requests.post('http://httpbin.org/post', data=payload)
#(PUT) 
r = requests.put('http://httpbin.org/put', data=payload)
#(DELETE) 
r = requests.delete('http://httpbin.org/delete', data=payload)

print(r.status_code)
print(r.text)
print(r.json())

The response of executing get will look like this.

output:

200

    "key1": "value1",

}
