如何在单击网页上的超链接时运行python脚本？

<a href="javascript:runPythonScript()">点击运行Python脚本</a>

<script>
function runPythonScript() {
  var xhr = new XMLHttpRequest();
  xhr.open("GET", "/run-python-script", true);
  xhr.onreadystatechange = function() {
    if (xhr.readyState === 4 && xhr.status === 200) {
      var response = xhr.responseText;
      // 处理脚本的输出
      console.log(response);
    }
  };
  xhr.send();
}
</script>

const express = require("express");
const { exec } = require("child_process");

const app = express();

app.get("/run-python-script", (req, res) => {
  exec("python script.py", (error, stdout, stderr) => {
    if (error) {
      console.error(`执行Python脚本时出错：${error}`);
      return res.status(500).send("执行Python脚本时出错");
    }
    console.log(`Python脚本的输出：${stdout}`);
    res.send(stdout);
  });
});

app.listen(3000, () => {
  console.log("服务器已启动");
});
