In Flask, the request object is used to access and process incoming HTTP request data, enabling communication between the client and the server. It provides various attributes and methods to handle different types of request data. For instance, request.args
retrieves query parameters from a GET
request, while request.form
extracts form data from a POST
request. JSON payloads can be using request.get_json()
, and file uploads are handled through request.files
. Aaccessed dditionally, request.method
identifies the HTTP method used (GET
, POST
, PUT
, etc.), and request.headers
allows access to metadata such as authentication tokens or content types. Flask’s request object is crucial for handling user inputs, processing API requests, and dynamically responding to client interactions, making it an essential component in building web applications and RESTful APIs.
