如何从ajax post函数中检索多个数据？

var data = {
  name: "John",
  age: 25,
  email: "john@example.com"
};

$.ajax({
  url: "your_server_url",
  type: "POST",
  dataType: "json",
  data: data,
  success: function(response) {
    // 处理服务器返回的响应数据
    console.log(response);
  },
  error: function(xhr, status, error) {
    // 处理请求错误
    console.error(error);
  }
});

app.post("/your_server_url", function(req, res) {
  var name = req.body.name;
  var age = req.body.age;
  var email = req.body.email;

  // 在这里处理接收到的数据，例如存储到数据库或进行其他操作

  // 返回响应数据
  res.json({ success: true, message: "Data retrieved successfully" });
});
