问题 I'm trying to hook up my backend with JWT authentication to a login component in Vue. This is my Vuex action: userLogin({commit}, payload) { axios.post('/users/token/obtain/', { email: payload.email, password: payload.password, }) .then(response => { localStorage.setItem('access', response.data.access) localStorage.setItem('refresh', response.data.refresh) let body = JSON.parse(atob(response.data.access.split('.')[1])) commit('userLogin', { userToken: response.data.access, userEmail: body

问题 I have alot of syncrhounous functions that i want to execute before that are basic ajax requests, these request will render html to the DOM. In order to do this i had to execute all of this synchrounous requests one by one. But i somehow want to these synchrounous functions asynchrounous all at the same time and wait for them to finnish in order to speed things up. This has to happen inside a synchrounous function. But my understanding is that this doesnt work in javascript, but i would like

问题 I have a method for validating a string, I want that method to return a Promise as the validations being ran may be asynchronous. The issue I am having however is one of performance, I want the promise to resolve in the same event loop when possible (eg: when there are no asynchronous validations to be done) but I want the interface to remain consistent (eg: to always return a Promise). The simplified code example below illustrates what I'm trying to do, but it incurs the aforementioned

问题 I am doing sorting in asc and desc . I want to make logic if User click first time I want to update it with name asc , when User click second time I want to update it with name desc . It will repeat same manner when ever user click.

问题 Updated , I've now tried explaining the behavior I'm seeing, but it'd still be great to have an answer from a credible source about the unhandledRejection behavor. I've also started a discussion thread on Reddit. Why do I get an unhandledRejection event (for "error f1") in the following code? That's unexpected, because I handle both rejections in the finally section of main . I'm seeing the same behavior in Node (v14.13.1) and Chrome (v86.0.4240.75): window.addEventListener(

问题 I want to do some validation on each refresh request for some routes. So I'm using Angular AuthGuard . The problem is in canActivate method I want to perform validation with online API. API is /token/verify which simply gets token variable (jwt) and verify if it's true or false. Then if verify is not complete will route to /login page else do the rest. Here is the code: canActivate(next: ActivatedRouteSnapshot, state: RouterStateSnapshot): Observable<boolean> | boolean { let token = this.auth
