【问题描述】：
此代码显示数据库中的医生列表，在用户选择医生后，我将他重定向到“/user/new_diagnosis/doctor/”页面，我想要发送用户选择的医生 ID服务器，所以我可以在“/user/new_diagnosis/doctor/”页面中使用它，请知道我该怎么做
server.js
app.get("/user/new_diagnosis",checkNotAuthenticated,(req, res) => {
db.query(
`SELECT * FROM doctor`,
(err, results) => {
if (err) {
console.log(err);
}
res.render("user-diagnosis",{doctors: results, name: req.user.userName ,surname: req.user.userSurname });
}
);
});
app.get("/user/new_diagnosis/doctor",checkNotAuthenticated,(req, res) => {
res.render("user-diagnosis-doctor");
});

如果这样做，经典的方法是 GET
/doctors/:doctorID。你可以在 Node/Express 中拥有一个类似app.get("/doctors/:doctorID", (req, res) => ...的路由，然后你在req.params.doctorID中获得 ID。然后，您可以在数据库中查找文档，获取完整的 Doctor 对象，使用它来呈现 Pug 模板，最后将呈现的模板（即 HTML）作为响应发送到浏览器。
