Detailed explanation of the technical principles of the Curly HTTP Client framework in the Java class library

Curly HTTP Client (hereinafter referred to as Curly) is a lightweight HTTP client framework for Java libraries.It is designed to simplify HTTP requests and response processing, and provides rich functions and APIs that are easy to use. Curly's technical principles can be explained in detail from the following aspects: 1. Java -based Netty framework: Curly uses Java's netty framework as the underlying network communication engine.Netty provides high -performance asynchronous event drive network application framework, which can handle a large number of concurrent connections and high loads. 2. Asynchronous and non -blocking processing: Curly uses asynchronous and non -blocking treatment methods to process HTTP requests and responses by callback mechanism.This processing method allows the application to initiate multiple parallel HTTP requests and process it when the asynchronous return, thereby improving the system's concurrent ability and response speed. 3. Support HTTP protocol: Curly supports the various characteristics of the HTTP protocol, including Get, Post, Put, Delete and other request methods, as well as the request head, response head, cookie, etc.It also supports the persistence and connection pool management of HTTP connection to improve the performance and efficiency between multiple HTTP requests. Here are some Curly Java code examples: 1. Initize a GET request and deal with response: Curly.get("https://api.example.com/users") .header("Authorization", "Bearer token") .execute((response) -> { int statusCode = response.getStatusCode(); String body = response.getBody(); // Processing response logic }); 2. Spot a post request and pass JSON data: Curly.post("https://api.example.com/users") .header("Content-Type", "application/json") .body("{\"name\": \"John\", \"age\": 30}") .execute((response) -> { int statusCode = response.getStatusCode(); String body = response.getBody(); // Processing response logic }); 3. Use the connection pool to manage the http connection: Curly.WithConnectionPool (10) // Set the size of the connection pool to 10 .get("https://api.example.com/users") .execute((response) -> { // Processing response logic }); It can be seen through these examples that Curly provides simple and powerful APIs to handle HTTP requests and responses.Its technical principles are mainly based on the Netty framework and asynchronous non -blocking processing methods, allowing developers to easily build an efficient HTTP client application.
