切勿运行控制器功能以外的响应操作。让另一个函数返回答案并根据答案进行决定。
router.post("/admins", async function (req, res) {
var newAdminObj = await newAdminObjectDecorator(req.body);
if (newAdminObj instanceof Error) {
return res.status(500).send()
}
var newAdmin = new Admins(newAdminObj)
newAdmin.save(function (err, saveresult) {
if (err) {
return res.status(500).send();
}
else {
return res.status(200).send();
}
});
});
// the function
var newAdminObjectDecorator = async function (entery) {
// doing some kinds of stuff in here
// if has errors return response with error code
if (err) {
// app continues after returning the error header response
return err;
}
else {
return result;
}
}
