Core Funcsionality
Basic Request Methods
Execute GET request:
response = requests.get("http://books.toscrape.com")
print(response.status_code) # 200
Execute POST request:
response = requests.post("https://jsonplaceholder.typicode.com/posts")
print(response.status_code) # 201
Response Handling
Check success status:
result = requests.get("https://www.example.org")
if result.ok:
print("Operation succeeded")
Parse JSON response:
api_response = requests.get("https://jsonplaceholder.typicode.com/posts/1")
data = api_response.json()
print(data["title"])
Handle binary content:
file_resp = requests.get("https://example.com/logo.png")
with open("logo.png", "wb") as output_file:
output_file.write(file_resp.content)
Advanced Feautres
Add query parameters:
query_params = {"category": "fiction", "limit": 10}
response = requests.get("https://api.example.com/books", params=query_params)
Submit form data:
form_data = {"username": "test_user", "password": "securepass"}
response = requests.post("https://auth.example.com/login", data=form_data)
Customize headers:
custom_headers = {
"User-Agent": "Mozilla/5.0 (X11; Linux x86_64)",
"Accept-Language": "en-US"
}
response = requests.get("https://example.com", headers=custom_headers)
Manage cookies:
session = requests.Session()
session.get("https://example.com/set_cookie")
authed_response = session.get("https://example.com/dashboard")
Bypass SSL verification:
import urllib3
urllib3.disable_warnings()
response = requests.get("https://self-signed.example.com", verify=False)
Set request timeout:
try:
response = requests.get("https://slow-api.example.com", timeout=2.5)
except requests.exceptions.Timeout:

resp = requests.get("https://www.example.com")
print(resp.headers)
print(resp.cookies)
print(resp.url)
