[英]How to send response to client if id could not find in mongo collection?
I am working on user authentication when user hit the application and is not part of user management collection i want to send user id to client so he can request access. 当用户点击应用程序但不属于用户管理集合时,我正在进行用户身份验证,我想将用户ID发送给客户端,以便他可以请求访问权限。 we are getting user information using csp cookies.
我们正在使用csp cookie获取用户信息。
So in below code if User
schema could not find useruid i want to send that information to client so user can use in request access form.with below code its throwing 404 when schema don't find useruid. 因此在下面的代码中,如果
User
架构找不到User
ID,我想将该信息发送给客户端,以便用户可以在请求访问表单中使用。下面的代码在架构找不到用户ID时抛出404。 Any idea how to resolve this issue ? 任何想法如何解决这个问题?
user.controller.js user.controller.js
function handleEntityNotFound(res) {
return function(entity) {
if (!entity) {
res.status(404).end();
return null;
}
return entity;
};
}
exports.current = function(req, res) {
// console.log('username', req);
User.findById(req.useruid)
.populate({path: 'groups', select: '_id name', options: {sort: {name: 1}}})
.execAsync()
.then(handleEntityNotFound(res))
.then(responseWithResult(res))
.catch(handleError(res));
};
If there's no match, findById() returns []
. 如果没有匹配项,则findById()返回
[]
。
Try: 尝试:
exports.current = function(req, res) {
User.findById(req.useruid, function (err, results) {
if (err) {
console.log(err);
}
if (results.length) {
responseWithResult(res);
} else {
handleEntityNotFound(res);
}
});
