Vue js beforeRouteEnter - laravel

I am using laravel and vuejs for my app and every user has a role. Now I want to restrict users to access vue routes by their roles by redirecting them to another route if they can't access the page. I am using beforeRouteEnter for vuejs but I am getting an error
data() {
return{
role: '',
}
},
mounted() {
axios.post('/getRole')
.then((response) => this.role = response.data)
.catch((error) => this.errors = error.response.data.errors)
},
beforeRouteEnter (to, from, next) {
if (this.role === 'Admin') {
next()
}else {
next('/')
}
}
I am getting this error
app.js:72652 TypeError: Cannot read property 'role' of undefined

you can't use this in beforeRouteEnter function,because before the route updates, your component's vm does not exist.
in consideration of you put role information in your vm, you can use next to get your vm:
beforeRouteEnter(to, from, next) {
next(vm => {
// put your logic here
if (vm.role === 'Admin') {
}
})
}
actually,you should use the Global Router Guard ,and put your role information in global area,so that your can redirect your routing before your target component created

Strapi returns 404 for custom route only when deployed to Heroku

I have created a custom route in Strapi v4 called "user-screens". Locally I hit it with my FE code and it returns some data as expected. However when I deploy it to Heroku and attempt to access the endpoint with code also deployed to Heroku it returns a 404. I've tailed the Heroku logs and can see that the endpoint is hit on the server side, but the logs don't give anymore info other than it returned a 404.
I am doing other non custom route api calls and these all work fine on Heroku. I am able to auth, save the token, and hit the api with the JWT token and all other endpoints return data. This is only happening on my custom route when deployed to Heroku. I've set up cors with the appropriate origins, and I am wondering if I need to add something to my policies and middlewares in the custom route. I have verified the permissions and verified the route is accessible to authenticated users in the Strapi admin.
Here is my route:
module.exports = {
routes: [
{
method: "GET",
path: "/user-screens",
handler: "user-screens.getUserScreens",
config: {
policies: [],
middlewares: [],
},
},
],
};
And my controller:
"use strict";
/**
* A set of functions called "actions" for `user-screens`
*/
module.exports = {
getUserScreens: async (ctx) => {
const user = ctx.state.user;
if (!user) {
return ctx.badRequest(null, [
{ messages: [{ id: "No authorization header was found" }] },
]);
}
strapi.entityService
.findMany("api::screen.screen", {
owner: user.id,
populate: ["image"],
})
.then((result) => {
ctx.send(result);
});
},
};
For anyone facing this, the answer was to change how I returned the ctx response from a 'send' to a 'return' from the controller method. I am not sure why this works locally and not on Heroku, but this fixes it:
New controller code:
module.exports = {
getUserScreens: async (ctx) => {
const user = ctx.state.user;
if (!user) {
return ctx.badRequest(null, [
{ messages: [{ id: "No authorization header was found" }] },
]);
}
return strapi.entityService
.findMany("api::screen.screen", {
owner: user.id,
populate: ["image"],
})
.then((result) => {
return result;
})
.catch((error) => {
return error;
});
},
};

Laravel Sanctum/Vuex Uncaught Error Vue Router Navigation Guard

Can anyone advise on this issue?
I've got a Laravel app with a Vue front-end, connecting to the API using Laravel Sanctum. (within the same application) I'm trying to set up the authentication guards so routes can only be accessed after authentication with the API.
I'm connecting through the state action like so:
async getAuthenticatedUser({ commit }, params) {
await axios.get('api/auth-user', { params })
.then(response => {
commit('SET_AUTHENTICATED', true)
commit('SET_AUTHENTICATED_USER', response.data)
localStorage.setItem('is-authenticated', 'true')
return Promise.resolve(response.data)
})
.catch(error => {
commit('SET_AUTHENTICATED', false)
commit('SET_AUTHENTICATED_USER', [])
localStorage.removeItem('is-authenticated')
return Promise.reject(error.response.data)
})
},
The state authenticated property is set as follows:
const state = () => ({
authenticated: localStorage.getItem('is-authenticated') || false,
authUser: [],
})
I have the following guard checking the auth. If I'm not signed in the app correctly redirects me back to the login screen when I access a route with the requiresAuth attribute.
However when I attempt to log in, I get Redirected when going from "/login" to "/dashboard" via a navigation guard.
router.beforeEach((to, from, next) => {
if (to.matched.some((record) => record.meta.requiresAuth)) {
if (store.getters["Auth/isAuthenticated"]) {
next()
return
}
next('/login')
}
if (to.matched.some((record) => record.meta.requiresVisitor)) {
if (! store.getters["Auth/isAuthenticated"]) {
next()
return
}
next('/dashboard')
}
next()
})
If it's safe to ignore, and you are using vue-router ^3.4.0, you can do:
import VueRouter from 'vue-router'
const { isNavigationFailure, NavigationFailureType } = VueRouter
...
this.$router.push(fullPath).catch(error => {
if (!isNavigationFailure(error, NavigationFailureType.redirected)) {
throw Error(error)
}
})

Get vuex store state after dispatching an action

I'm creating a chat application in Laravel 6 + Vue + Vuex. I want make a call to vuex store and get a state after a dispatch actions is complete and then I want to do some processing on that state in my vue component.
In ChatWindow component
mounted: function () {
this.$store.dispatch('setContacts').then(() => {
console.log('dispatch called')
// I want to call the getter here and set one of the data property
});
}
action.js
setContacts: (context) => {
axios.post('/users').then(response => {
let users = response.data;
// consoled for testing
console.log(users);
context.commit('setContacts', users);
});
}
mutators.js
setContacts: (state, users) => {
state.contacts = users;
},
Please see the screenshot below. The then method of dispatch is running before setContacts in action.js.
I need to call the getter after completing dispatch action. (which will effectively set the contacts state). Then, I want to get the contacts through getContacts getter like this.
getters.js
getContacts: (state) => {
return state.contacts;
}
I also tried calling computed property in then in mounted and it didn't work. Also, shouldn't 'dispatch called' in mounted run after console.log of setContacts in action.js as it is in then method? Thanks!
Maybe you could wrap axios call inside another promise.
return new Promise((resolve, reject) => {
axios.post('/users')
.then(response => {
let users = response.data;
// consoled for testing
console.log(users);
context.commit('setContacts', users);
resolve('Success')
})
.catch(error => {
reject(error)
})
})
And then
this.$store.dispatch('setContacts')
.then(() => {
console.log('dispatch called')
console.log('getter ', this.$store.getters.contacts)
});
Let me know what happens. It was working for a small demo that I tried.

Load current user with Vue/Axios in Laravel

Okay I'm trying to find the best way to load the current user into my vue app so that I can pull the username and ID from any other component or route.
Right now I've tried this:
app.js
new Vue({
el: '#app',
computed: {
user(data) {
return new Promise((resolve, reject) => {
axios.get('/current-user')
.then(response => {
resolve(response.data);
console.log(response.data);
})
.catch(error => {
reject(error.response.data);
});
});
}
},
router
});
It will log my user just fine, but I can't call #{{ user }} in any blade file. How exactly am I supposed to get the current user on app initialization?
Your user computed property returns Promise object not desired value.
Below is my proposition of solving your problem. You should be able to succesfully call #{{ user }} within your blade files. However to access user property in children components you are forced to use $parent.user property of theirs.
Personally I recommend you checking out Vuex which is made for such cases. It is centralized state storing solution allowing you to access (and manage) data from all over your app.
new Vue({
el: '#app',
data () {
return {
user: null
};
},
created () {
// As app intializes user is fetched and saved
this.fetchUser();
},
methods: {
fetchUser () {
axios.get('/current-user')
.then(response => {
this.user = response.data;
})
.catch(error => {
alert('Something went wrong');
console.error(error.response.data);
});
}
},
router
});

How to make the delay when a user check on Vue.js?

I have SPA application on Vue.js + Laravel. Authorization logic, completely delegated to Laravel app. However, i need check auth status, when routing has changed. I create small class, which responsible for it.
export default {
user: {
authenticated : false
},
check: function(context) {
context.$http.get('/api/v1/user').then((response) => {
if (response.body.user != null) {
this.user.authenticated = true
}
}, (response) =>{
console.log(response)
});
}
Within the component has a method that is called when a change url.
beforeRouteEnter (to, from, next) {
next(vm =>{
Auth.check(vm);
if (!Auth.user.authenticated) {
next({path:'/login'});
}
})
}
Function next() given Vue app instance, then check user object. If user false, next() call again for redirect to login page. All it works, but only when the page is already loaded. If i'll reload /account page, there is a redirect to /login page, because request to Api not completed yet, but code will continue execute. Any idea?
Quite simple to do, you need to make your code work asynchronously and hold routing before request is completed.
export default {
user: {
authenticated : false
},
check: function(context) {
return context.$http.get('/api/v1/user').then((response) => {
if (response.body.user != null) {
this.user.authenticated = true
}
}, (response) => {
console.log(response)
});
}
}
then
beforeRouteEnter (to, from, next) {
next(vm => {
Auth.check(vm).then(() => {
if (!Auth.user.authenticated) {
next({path:'/login'});
} else {
next()
}
}
})
}
Other pro tips
Display some loading indicator when loading so your application doesn't seem to freeze (you can use global router hooks for that)
If you are using vue-resource, consider using interceptors (perhaps in addition to the routing checks)
Consider using router.beforeEach so that you don't have to copy-paste beforeRouteEnter to every component
Done. Need to return promise like that
check: function(context) {
return context.$http.get('/api/v1/user').then((response) => {
if (response.body.user != null) {
this.user.authenticated = true
}
}, (response) =>{
console.log(response)
});
}
and then
beforeRouteEnter (to, from, next) {
Auth.check().then(()=>{
if(!Auth.user.authenticated)
next({path:'/login'})
else
next();
})
}
