如何接受来自HTML表单的HTTP请求形式的语言列表？

<?php
// 获取表单数据
$languageList = $_POST['language'];

// 处理表单数据
foreach ($languageList as $language) {
    echo $language . "<br>";
}
?>

from flask import Flask, request

app = Flask(__name__)

@app.route('/', methods=['POST'])
def process_form():
    # 获取表单数据
    language_list = request.form.getlist('language')

    # 处理表单数据
    for language in language_list:
        print(language)

    return 'Form submitted successfully'

if __name__ == '__main__':
    app.run()

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;

@SpringBootApplication
@RestController
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

    @PostMapping("/")
    public String processForm(@RequestBody FormData formData) {
        // 获取表单数据
        String[] languageList = formData.getLanguage();

        // 处理表单数据
        for (String language : languageList) {
            System.out.println(language);
        }

        return "Form submitted successfully";
    }
}

class FormData {
    private String[] language;

    public String[] getLanguage() {
        return language;
    }

    public void setLanguage(String[] language) {
        this.language = language;
    }
}
