What are HTTP Requests?
HTTP Requests are often used to communicate to an external server from the client (your browser).
For example, you want to get data from a website.
To do that in Python the easy way, you can use the requests module.
GET, POST, PUT and DELETE
GET Requests are used to fetch data from a server.
POST Requests are used to send data to the server and (sometimes, based on the server) recieve some data relevant to what you have sent.
PUT Requests are used to update some data on the server (if it allows it).
DELETE Requests are used to delete some data on the server (if it allows it as always).
Using the Requests Module
Example for a GET Request
import requests
URL = "https://exampleDATABASE.comp/"
response = requests.get(URL)
data = response.json()
print(data)
Here, we are getting the data from an example (fake) database.
First we import the requests module
Then we use requests.get() to make a GET request from the url URL
After that we convert the raw data to JSON.
Then we print the data.
Example for a POST Request
import requests
URL = "https://exampleDATABASE.comp/"
dataToPost = {"key1": "value1", "key2": "value2"}
response = requests.post(URL, data=dataToPost)
print(response) # Outputs: "key 1 is value1", "key 2 is value2" ### FOR EXAMPLE
Here we are using the same database, but using POST Request.
First we make a variable that stores some data.
Then we use that data to post it to the server by calling requests.post().
If so, the database/server will respond to that data.
NOTICE: This will not update the database. If it supports that.
Example for a PUT Request
import requests
URL = "https://exampleDATABASE.comp/"
dataToPut = {"key1": "value1", "key2": "value2"}
response = requests.put(URL, data=dataToPut)
print(response) # Outputs: 200 ### OK
Here we are using the same database, but using PUT Request.
First we make a variable that stores some data.
Then we use that data to put it in the server by calling requests.put().
NOTICE: The server will get updated by your data, if it supports that.
Example for a DELETE Request
import requests
URL = "https://exampleDATABASE.comp/"
requests.delete("https://exampleDATABASE.comp/16soth.html")
Here we are using the same database, but using DELETE Request.
Then we delete the data from 16soth.html by calling requests.delete().
NOTICE: The server will get updated by your data, if it supports that.
So, that's it.
Hope it was helpful.
