Not able to access token using axios and djangorestframework-jwt - vue.js

Question

I am trying to make an application which servers api through django rest framework and the frontend is done in vue.js2.
I am referring this blog to help me authenticating jwt via axios. I also tried this one when I couldn't make the first one run correctly
Here is my settings.py file
INSTALLED_APPS = [
...

]
# Password validation

}
#Cors origin
CORS_ORIGIN_WHITELIST = (
'localhost:8080'
)
CORS_ORIGIN_ALLOW_ALL = True
CORS_ALLOW_CREDENTIALS = True
Here is my vue store
axios.defaults.xsrfCookieName = 'csrftoken'
axios.defaults.xsrfHeaderName = 'X-CSRFToken'
export default new Vuex.Store({
state: {
authUser: {},
isAuthenticated: false,
jwt: localStorage.getItem('token'),
endpoints: {
obtainJWT: 'http://127.0.0.1:8000/api/v1/auth/obtain_token/',
refreshJWT: 'http://127.0.0.1:8000/api/v1/auth/refresh_token/',
baseUrl: 'http://127.0.0.1:8000/api/v1'
}
},
mutations: {
setAuthUser(state, {
authUser,
isAuthenticated
}) {
Vue.set(state, 'authUser', authUser)
Vue.set(state, 'isAuthenticated', isAuthenticated)
},
updateToken(state, newToken) {
localStorage.setItem('token', newToken);
state.jwt = newToken;
},
removeToken(state) {
localStorage.removeItem('token');
state.jwt = null;
}
},
actions: {
obtainToken(context, {username, password}) {
const payload = {
username: username,
password: password
}
const headers= {
'Content-Type': 'application/json'
}
axios.post(this.state.endpoints.obtainJWT, headers, payload)
.then((response) => {
this.commit('updateToken', response.data.token);
console.log(this.state.jwt);
})
.catch((error) => {
console.log(error);
})
},
refreshToken () {
const payload = {
token: this.state.jwt
}
axios.post(this.state.endpoints.refreshJWT, payload)
.then((response) => {
this.commit('updateToken', response.data.token);
console.log(this.state.jwt)
})
.catch((error) => {
console.log(error)
})
}
}
})
and here is login.vue
<script>
import axios from 'axios'
import FormInput from './FormInput'
export default {
name: 'Login',
components: {
FormInput
},
data () {
return {
username: '',
password: ''
}
},
computed: {
/* ...mapState([
'jwt',
'endpoints'
]) */
},
methods: {
/* ...mapActions([
'obtainToken'
]), */
authenticateBeforeSubmit () {
this.$store.dispatch('obtainToken', {
username: this.username,
password: this.password
}).then(() => {
this.$router.push('/')
}).catch((error) => {
console.log(error)
})
/* const payload = {
username: this.username,
password: this.password
}
axios.post(this.$store.state.endpoints.obtainJWT, payload)
.then((response) => {
this.$store.commit('updateToken', response.data.token)
console.log(this.$store.state.jwt);
const base = {
baseUrl: this.$store.state.endpoints.baseUrl,
headers: {
Authorization: `JWT ${this.$store.state.jwt}`,
'Content-Type': 'application/json'
},
xhrFields: {
withCredentials: true
}
}
const axiosInstance = axios.create(base)
axiosInstance({
url: "/user/",
method: "get",
params: {}
})
.then((response) => {
this.$store.commit("setAuthUser",
{authUser: response.data, isAuthenticated: true}
)
this.$router.push({name: 'Home'})
})
})
.catch((error) => {
console.log(error);
console.debug(error);
console.dir(error);
}) */
}
}
}
</script>
Now the problem is I am getting two errors
Just as I load login view in browser, i get this error
Uncaught (in promise) TypeError: Cannot read property 'protocol' of undefined
at isURLSameOrigin (VM34519 isURLSameOrigin.js:57)
at dispatchXhrRequest (VM34513 xhr.js:109)
at new Promise ()
at xhrAdapter (VM34513 xhr.js:12)

dispatchRequest # VM34521 dispatchRequest.js:59
18:29:09.976
I don't have slightest idea what this error is about, I searched it and i didn't find anything that works
This I get when I click submit which fires authenticateBeforeSubmit method
Uncaught TypeError: Cannot read property 'dispatch' of undefined
at VueComponent.authenticateBeforeSubmit (VM34576 Login.vue:68)
at invoker (VM34494 vue.esm.js:2026)

invoker # VM34494 vue.esm.js:2026
fn._withTask.fn._withTask # VM34494 vue.esm.js:1825
18:29:30.912
What i understand it is saying that i am calling dispatch on action incorrectly but i don't get how to make it work
As I click submit it "redirects" to
http://127.0.0.1:8080/login?username=f1uk3r&password=thisissparta
but it doesn't recieves any token
I have tested token using
curl -X POST -H "Content-Type: application/json" -d '{"username":"f1uk3r","password":"thisissparta"}' http://127.0.0.1:8000/api/v1/auth/obtain_token/
and it gives me a token so there shouldn't be any problem in django part I think. What am I doing wrong, how can I rectify it.

Answer 1

I figured it out, so answering for future reference and if anybody else finds this useful
TypeError: Cannot read property 'protocol' of undefined at isURLSameOrigin
this can be solved by importing axios and VueAxios correctly
I initialized it like this
import Vue from 'vue'
import VueAxios from 'vue-axios'
import Vuex from 'vuex'
import axios from 'axios'
Vue.use(Vuex);
Vue.use(axios, VueAxios);
While it should have been initialized like this
import Vue from 'vue'
import VueAxios from 'vue-axios'
import Vuex from 'vuex'
import axios from 'axios'
Vue.use(Vuex);
Vue.use(VueAxios, axios);
Cannot read property 'dispatch' of undefined at VueComponent
Again I wasn't initializing store correctly so i made a directory in "src" directory named it "store" and in this directory I made a file named "store.js"
Then in main.js import store and initialize in the instance
import store from './store/store.js';
Vue.use(VeeValidate);
/* eslint-disable no-new */
new Vue({
el: '#app',
router,
store,
components: { App },
template: '<App/>'
})
