1. Basic GET Request

To fetch data from an API endpoint using a GET request:

import requests
response = requests.get('https://api.example.com/data')
data = response.json()  # Assuming the response is JSON
print(data)

2. GET Request with Query Parameters

To send a GET request with query parameters:

import requests
params = {'key1': 'value1', 'key2': 'value2'}
response = requests.get('https://api.example.com/search', params=params)
data = response.json()
print(data)

3. Handling HTTP Errors

To handle possible HTTP errors gracefully:

import requests
response = requests.get('https://api.example.com/data')
try:
    response.raise_for_status()  # Raises an HTTPError if the status is 4xx, 5xx
    data = response.json()
    print(data)
except requests.exceptions.HTTPError as err:
    print(f'HTTP Error: {err}')

4. Setting Timeout for Requests

To set a timeout for API requests to avoid hanging indefinitely:

import requests
try:
    response = requests.get('https://api.example.com/data', timeout=5)  # Timeout in seconds
    data = response.json()
    print(data)
except requests.exceptions.Timeout:
    print('The request timed out')

5. Using Headers in Requests

To include headers in your request (e.g., for authorization):

import requests
headers = {'Authorization': 'Bearer YOUR_ACCESS_TOKEN'}
response = requests.get('https://api.example.com/protected', headers=headers)
data = response.json()
print(data)

6. POST Request with JSON Payload

To send data to an API endpoint using a POST request with a JSON payload:

import requests
payload = {'key1': 'value1', 'key2': 'value2'}
headers = {'Content-Type': 'application/json'}
response = requests.post('https://api.example.com/submit', json=payload, headers=headers)
print(response.json())

7. Handling Response Encoding

To handle the response encoding properly:

import requests
response = requests.get('https://api.example.com/data')
response.encoding = 'utf-8'  # Set encoding to match the expected response format
data = response.text
print(data)

8. Using Sessions with Requests

To use a session object for making multiple requests to the same host, which can improve performance:

import requests
with requests.Session() as session:
    session.headers.update({'Authorization': 'Bearer YOUR_ACCESS_TOKEN'})
    response = session.get('https://api.example.com/data')
    print(response.json())

9. Handling Redirects

To handle or disable redirects in requests:

import requests
response = requests.get('https://api.example.com/data', allow_redirects=False)
print(response.status_code)

10. Streaming Large Responses

To stream a large response to process it in chunks, rather than loading it all into memory:

import requests
response = requests.get('https://api.example.com/large-data', stream=True)
for chunk in response.iter_content(chunk_size=1024):
    process(chunk)  # Replace 'process' with your actual processing function

HTTPS도 보고 싶다면 아래와 같이 

Tools - Options - HTTPS - check!

...

이제 HTTPS는 필수다. https://www.httpvshttps.com/

구글, 페이스북, 트위터 깃허브, 유튜브는 모든 페이지를 HTTPS로 적용해 운영하고 있다. 

http://로 접속해도 https://로 이동하도록 되어있다. 

하지만 https 일때 http로 호출되는 것은 모두 요청이 제한되기 때문에 충분히 검토 후 적용해야 한다.
