问题 I want to render a new HTML page on user request, which is only accessible if the authorization header is set correctly. I initially thought that the browser would redirect to the page, but found out that this is not the case. I have found some ways to handle this, for example replacing the DOM, but I don't think that is a good solution. Here is the fetch call from UI, which returns the HTML, but does not render it currently: fetch('/protected_route', { headers: { 'authorization': 'Bearer ' +

问题 I'm trying to retrieve a list of objects and send them back to my mobile app. I'm just having some difficulty actually sending them after the forEach loop is over. I tried appending that variable "data" to an array and sending it outside of the loop but the array is empty. Obviously, there is data being retrieved, but it doesn't get pushed into the array on time. How can I make sure the loop is over before I call res.send() ? I reduced the code as much as I could to make it as simple as

问题 let's say I've got a function where I'm fetching for some data from a DB. findById(id) { return Model.findById(id) } I need to reorganize the return from the user data like this: { name: "Tom", age: 57 } into something like this: { message: "User is found successfully", success: true, user: user } So far I can manage with that with a Promise "then" section, like this: return Model.findById(id) .then(user => { if (!user) { logger.warn(`Coundn't find user with id: ${id}`); return { message:
