Python HTTP Requests

Python applications often communicate with web APIs using HTTP requests. The requests library provides a simple interface for sending HTTP requests and processing responses.

Install Requests

              
            
TEXT
Install the requests library with pip.
pip install requests

GET Request

              
            
Python
Send a GET request and read the response.
import requests

response = requests.get("https://example.com")

print(response.status_code)
print(response.text)

Query Parameters

              
            
Python
Send query parameters with a GET request.
import requests

params = {
    "page": 1,
    "limit": 10
}

response = requests.get("https://example.com/api/users", params=params)
print(response.url)

POST Request

              
            
Python
Send JSON data with a POST request.
import requests

payload = {
    "name": "Alice",
    "age": 25
}

response = requests.post(
    "https://example.com/api/users",
    json=payload
)

print(response.status_code)

Read JSON Response

              
            
Python
Convert a JSON response into Python data.
import requests

response = requests.get("https://example.com/api/users")
data = response.json()

print(data)

HTTP Headers

              
            
Python
Send custom HTTP headers.
import requests

headers = {
    "Authorization": "Bearer TOKEN",
    "Accept": "application/json"
}

response = requests.get(
    "https://example.com/api/users",
    headers=headers
)

Handle Request Errors

              
            
Python
Raise an exception for HTTP errors.
import requests

try:
    response = requests.get("https://example.com/api/users", timeout=5)
    response.raise_for_status()
    print(response.json())
except requests.RequestException as error:
    print("Request failed:", error)

Summary

The requests library makes HTTP communication simple in Python. You can send GET and POST requests, pass parameters and headers, process JSON responses, and handle network errors.
