How to Parse Multipart Form Data in Python
Parse multipart/form-data uploads using the Python standard library's cgi module to extract both regular fields and file uploads.
import cgi
from io import BytesIO
def parse_multipart_form(headers, body_bytes):
content_type = headers.get("Content-Type", "")
content_length = int(headers.get("Content-Length", len(body_bytes)))
# Create a file-like object from bytes for cgi.FieldStorage
body_file = BytesIO(body_bytes)
…Verify Webhook HMAC Signatures in Python
Create and verify HMAC-SHA256 signatures for webhook payloads using Python's hmac module, protecting against tampering.
import hashlib
import hmac
import json
SECRET = b"super-secret-webhook-key"
def create_signature(payload: bytes) -> str:
return hmac.new(SECRET, payload, hashlib.sha256).hexdigest()
def verify_signature(payload: bytes, signature: str) -> bool:
expected = create_signature(payload)
return hmac.compare_dig…Browse by section
