伺服器端腳本是 Web 開發的重要面向。它涉及編寫在伺服器上運行的腳本來生成動態網頁、處理用戶請求以及與資料庫互動。伺服器端腳本通常使用多種程式語言,每種語言都有自己的優勢和用例。讓我們深入探討一些最受歡迎的伺服器端腳本語言:
<?php echo "Hello, World!"; ?>
from flask import Flask app = Flask(__name__) @app.route('/') def hello_world(): return 'Hello, World!' if __name__ == '__main__': app.run()
const http = require('http'); const server = http.createServer((req, res) => { res.statusCode = 200; res.setHeader('Content-Type', 'text/plain'); res.end('Hello, World!\n'); }); server.listen(3000, '127.0.0.1', () => { console.log('Server running at http://127.0.0.1:3000/'); });
require 'sinatra' get '/' do 'Hello, World!' end # Run the application with: ruby app.rb
多執行緒:高效處理多執行緒,適合高效能應用。
企業級 Web 應用程式。
Android 應用程式開發。
大型系統。
範例程式碼:
import java.io.*; import javax.servlet.*; import javax.servlet.http.*; public class HelloWorldServlet extends HttpServlet { public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException { response.setContentType("text/html"); PrintWriter out = response.getWriter(); out.println("<h1>Hello, World!</h1>"); } }
Each server-side scripting language has its unique features and is suited for different types of projects. PHP and Python are known for their ease of use and rapid development capabilities. Node.js offers excellent performance for real-time applications. Ruby provides an elegant and productive development environment, while Java is a strong choice for enterprise-level solutions. Understanding these languages and their frameworks can help you choose the right tool for your server-side scripting needs.
