如何将表单输入作为变量传递给我的类方法

<form>
  <input type="text" name="inputValue">
  <input type="submit" value="Submit">
</form>

from flask import Flask, request

app = Flask(__name__)

@app.route('/', methods=['POST'])
def process_form():
    input_value = request.form['inputValue']
    # 调用类方法并传递input_value作为参数
    MyClass.my_method(input_value)
    return 'Form submitted successfully'

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

const express = require('express');
const app = express();

app.use(express.urlencoded({ extended: true }));

app.post('/', (req, res) => {
    const input_value = req.body.inputValue;
    // 调用类方法并传递input_value作为参数
    MyClass.myMethod(input_value);
    res.send('Form submitted successfully');
});

app.listen(3000, () => {
    console.log('Server started on port 3000');
});

if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    $input_value = $_POST['inputValue'];
    // 调用类方法并传递input_value作为参数
    MyClass::myMethod($input_value);
    echo 'Form submitted successfully';
}
