Learn from the FM HTTP framework in the Java class library

The FM HTTP framework (FM HTTP Framework) is an open source framework widely used in the Java library to build a high -performance HTTP application.It provides a simple and elegant way to handle HTTP requests and responses, and it is easy to integrate into existing Java projects.This article will introduce the characteristics and usage of the FM HTTP framework and provide some Java code examples. 1. Framework characteristics The FM HTTP framework has the following characteristics and functions: 1.1 High performance: The FM HTTP framework uses asynchronous non -blocking IO models, which can process a large number of concurrent requests to provide excellent performance. 1.2 Lightweight: The entire framework is very lightweight. It only relies on a small number of third -party libraries and is easy to deploy and maintain. 1.3 Easy -to -use: FM HTTP framework provides simple APIs, enabling developers to quickly build HTTP applications. 1.4 Scalability: The framework provides a flexible expansion mechanism that can easily customize and enhance the function of the framework. 1.5 Support multiple HTTP request methods: FM HTTP framework supports common HTTP request methods, such as Get, POST, PUT, Delete, etc. 1.6 Routing function: The framework provides the routing function. You can forward the request to a specific processor function according to the URI mode. 2. Use examples Below is a simple example, demonstrating how to use the FM HTTP framework to process the HTTP request. First, you need to add the FM HTTP framework to the Maven or Gradle project: dependencies { // Maven <dependency> <groupId>io.github.fm-kt</groupId> <artifactId>fm-http</artifactId> <version>1.0.0</version> </dependency> // Gradle implementation 'io.github.fm-kt:fm-http:1.0.0' } Next, create a HTTP server in the Java class and define the function of processing requests: import io.github.fmkt.HttpServer; import io.github.fmkt.Request; import io.github.fmkt.Response; public class MyHttpServer { public static void main(String[] args) { HttpServer server = new HttpServer(); // Define the routing rules, forward the "/hello" get request to the handlehello function server.get("/hello", MyHttpServer::handleHello); // Start the http server server.start(8080); } public static void handleHello(Request request, Response response) { // Get the request parameter String name = request.queryParam("name"); // Construction response content String responseBody = "Hello, " + (name != null ? name : "World") + "!"; // Send response response.send(200, responseBody); } } In the above example, we created a HTTP server and defined a routing rule to forward the GET request of "/Hello" to the Handlehello function.The handlehello function receives a Request object and a Response object. Through these two objects, you can obtain and send the HTTP request and response.In this example, we constructed a simple response based on the request parameter, and used the Response object to send it back to the client. Through the above simple examples, we can see the simplicity and ease of use and flexibility of the FM HTTP framework.Developers can use the FM HTTP framework to quickly build high -performance HTTP applications according to their own needs. Summarize This article introduces the characteristics and usage of the FM HTTP framework, and provides a simple example to demonstrate how to use the framework to build an HTTP application.It is hoped that through the introduction of this article, readers can learn more about the FM HTTP framework and apply its advantages in actual projects.
