A library for checking if JSON requests have valid data.
Project description
FlaskRequestGuard
Flask Request Guard is a Python library for validating incoming HTTP requests in Flask web applications. It provides a simple yet flexible way to define request rules and enforce them automatically on incoming requests, ensuring that only requests that meet the specified requirements are allowed to proceed.
Installation
Use the package manager pip to intall flask-request-gaurd.
pip install flask-guard
Create the keys
from FlaskGuard import RequestParameter
# Creates a key that has the name "name" and type str with a minimum length of 0 and
# a maximum length of 10
name_key = RequestParameter("name", str, 0, 10)
# Creates a key that has the name "range" and type int with a minimum value of -10 and
# a maximum value of 10
range_key = RequestParameter("range", int, -10, 10)
Create the validation function
from FlaskGuard import FlaskGuard
# Init FlaskRequestGuard
guard = FlaskRequestGuard("myapp")
# Keys from the code snippet above
required_keys = [range_key, name_key]
# Returns a function that is used to check a request
validate_user_request = guard.create_validate_function(required_keys)
Check request
request = {"name": "erik", "age": 23, "range": 2}
# Returns (True, {"error_messages": []})
is_valid, error_messages = validate_user_request(request)
request = {"name": "eeeeeeeeeee", "age": 23, "range": 2}
# Returns (False, {"error_messages": ["The 'name' field must be 10 size or less,
# and at least 0 size or more, but is actually 11 characters long."]})
is_valid, error_messages = validate_user_request(request)
request = {"age": 23, "range": 2}
# Returns False, {"error_messages": ["Missing name field in request body."]}
is_valid, error_messages = validate_user_request(request)
