如何从控制器获取1-20复选框的值​？

<input type="checkbox" name="checkbox1" value="1">
<input type="checkbox" name="checkbox2" value="2">
...
<input type="checkbox" name="checkbox20" value="20">

$checkboxValues = array();
for ($i = 1; $i <= 20; $i++) {
    if (isset($_POST['checkbox'.$i])) {
        $checkboxValues[] = $_POST['checkbox'.$i];
    }
}

from flask import request

checkboxValues = []
for i in range(1, 21):
    if 'checkbox'+str(i) in request.form:
        checkboxValues.append(request.form['checkbox'+str(i)])

import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestParam;

@PostMapping("/submitForm")
public String submitForm(@RequestParam Map<String, String> formData) {
    List<String> checkboxValues = new ArrayList<>();
    for (int i = 1; i <= 20; i++) {
        if (formData.containsKey("checkbox"+i)) {
            checkboxValues.add(formData.get("checkbox"+i));
        }
    }
    // 其他处理逻辑
}
