In Flask, the request object is used to access and process incoming HTTP request data, enabling interaction between clients and the server. It is an instance of flask.request and provides various attributes to handle different types of data. For instance, request.args retrieves query parameters from a URL in a GET request, while request.form extracts form data from a POST request. JSON payloads can be accessed using request.get_json(), and file uploads are handled through request.files. Additionally, request.method helps determine the HTTP method used (GET, POST, PUT, etc.), and request.headers provides metadata such as authentication tokens or content types. Flask’s request object is essential for handling user inputs, making dynamic web applications possible by allowing data retrieval and processing based on client requests.
