The main component and core function introduction of the Script API framework

The Script API framework is a development framework for building and managing API.It provides a set of core components and functions that enable developers to create and manage API services more easily.The main components and core functions of the Script API framework are introduced below. 1. Router: The router is an important component in the Script API framework for management and distributing API requests.It can make the request routing in the corresponding processing program according to the requested URL path and the HTTP method.Developers can define multiple endpoints of the API through configuration routers, and select the correct processing procedure according to different types and parameters. 2. Handler: The processing program is a place to define the logic and behavior of the API.It contains the code logic of processing requests, executing the required operation, and generating corresponding response.Developers can create multiple processing procedures as needed and configure them in the router.The processing program usually contains verification requests, execute business logic, access database or other services, and generates corresponding results. 3. Middleware: The middle part is a component located between the request and processing program to process the pre -processing and post -processing operation of the request.It can verify the request, authentication, authorization, log record and other operations.Developers can use existing middleware or writing custom middleware to add the required functions. 4. Parameter Parser: The parameter parser is used to analyze and process parameters in the request.It can analyze the parameters from the URL path, query string, request body, etc., and convert them into formats that can be used by processing programs.The parameter parser can help developers handle parameters of different types and formats and provide appropriate errors. 5. Response generator (Response Generator): The response generator is used to generate API responses.It can convert the data returned by the processing program into an appropriate response format, such as JSON, XML or HTML.Developers can write customized response generators as needed, and choose formats and structures suitable for its API. When using the SCRIPT API framework, developers usually need to configure some configuration and encoding to set up routing, processing programs, middleware, etc. of the API.Here are some of the program code and related configuration examples that may be required: Example 1: Configure routers and processing programs python # Import the required library from script_api import Router # 创 创 router = Router() # Define the routing and processing program router.add_route('/api/users', 'GET', get_users_handler) router.add_route('/api/users/{id}', 'GET', get_user_handler) router.add_route('/api/users', 'POST', create_user_handler) # Start the application and start listening to the request router.start() Example 2: Process program example python # Import the required library from script_api import Request, Response # Treatment program sample def get_users_handler(request: Request) -> Response: # Get user data from the database users = UserDB.get_all_users() # Generate response and return response = Response(json.dumps(users), 200, {'Content-Type': 'application/json'}) return response Example 3: Middleware example python # Import the required library from script_api import Middleware # Example class AuthMiddleware(Middleware): def handle_request(self, request: Request) -> None: # Verify the identity information of the request if not request.headers.get('Authorization'): # If the identity verification fails, return to the unauthorized response response = Response('Unauthorized', 401) raise self.abort(response) def handle_response(self, response: Response) -> None: #An post -processing operation for response # Here you can perform logging, response time calculation and other operations pass The script API framework provides a convenient and flexible way to build and manage API services.Developers can use and extend the framework of the framework according to their own needs, and define the behavior and response of the API by writing the corresponding code and configuration.
