Question

我有麻烦了...

在我的应用程序中注册后，用户需要创建一个工作区，我需要强制创建工作区，否则API将无法正常工作，但是我无法将其锁定在工作区创建页面上。

当我尝试检查用户在应用程序的第一次加载时是否已经有工作区时，由于axios请求尚未完成，vuex仍然为空...

如何确定vue路由器将等待axios接收api数据？

router.js

import Vue from 'vue'
import Router from 'vue-router'
import store from './../store'

import auth from './modules/auth'
import api from './modules/api'
import common from './modules/common'
import projects from './modules/projects'
import wabas from './modules/wabas'

Vue.use(Router)

const router = new Router({
    mode: 'history',
    base: process.env.BASE_URL,
    routes: [
        ...auth,
        ...api,
        ...common,
        ...projects,
        ...wabas,
    ]
})

router.beforeEach((to, from, next) => {
    store.dispatch('auth/setToken').then(() => {
        // will return an empty array
        console.log(store.getters['workspaces/workspaces'])
        if (!store.state.workspaces.workspaces.length && to.name !== 'welcome_a' && to.name !== 'welcome_b' && to.name !== 'welcome_c') {
            next({
                name: 'welcome_a'
            })
        } else {
            if (to.meta.visitor || to.name === 'welcome_a' || to.name === 'welcome_b' || to.name === 'welcome_c') {
                next({
                    name: 'home'
                })
                return
            }

            next()
        }
    }).catch(() => {
        if (to.meta.auth) {
            next({
                name: 'login'
            })
            return
        }

Answer 1

从该问题的标题开始，您可以在vue组件中添加一个钩子，该钩子将在更改路线之前运行

beforeRouteLeave (to, from, next) {
    // called when the route that renders this component is about to
    // be navigated away from.
    // has access to `this` component instance.
  }

如果您希望用户移动到他单击的下一条路线，则将在此挂接内调用next()，并将其导航到下一页。

如果您想锁定他而不导航，请使用next()之类的next(false)方法传递false

为什么不创建一个中间件服务器端，如果用户还没有的话，它将用户重定向到工作区创建页面？ laravel之类的东西

class RedirectIfWorkspaceNotCreated
{

    public function handle($request, Closure $next, $guard = null)
    {
        $user = Auth::guard($guard)->user();

        if ($user && !checkForUserWorkspace) {
            return redirect('/your/workspace/creation/page');
        }

        return $next($request);
    }
}
