Python Webargs Class Library Technical Principles
The Python Webargs Class Library Technical Principles
Webargs is a Python library that provides a simple and consistent interface for parsing HTTP request bodies. It allows developers to easily validate and parse JSON, XML, or other data formats in requests, without having to write custom parsing code.
python
import webargs
from webargs import fields
schema = {
'username': fields.String(required=True),
'email': fields.Email(required=True)
}
@app.route('/login', methods=['POST'])
def login():
data = request.get_json()
username = data.get('username')
email = data.get('email')
validate(schema, {'username': username, 'email': email})
# ...
In this example, the `validate` decorator is used to apply the schema to the API endpoint function. The `request.get_json()` method is used to parse the JSON format request body. If the data validates against the schema, the application can proceed with the logic to handle the login request.
