Vue.js with Axios use data from other method - vue.js

Question

I have a external api which returns a json of a user with some attributes like username. I want to use this username in my vue methods as a url parameter and defined the function getUser(). My problem is that the parameter keeps undefined
Here is my code
<script>
import Axios from 'axios-observable'
export default {
data () {
return {
appointments: {},
event_counter: 0,
user: ''
},
methods: {
getUser: function () {
Axios
.get('http://127.0.0.1:5000/users/get_user')
.subscribe(response => { this.user = response.data.username })
},
getAppointments: function () {
Axios
.get('http://127.0.0.1:5000/appointments/get_appointments?user=' + this.user)
.subscribe(response => { this.appointments = response.data })
},
fetchData: function () {
setInterval(() => {
this.getAppointments()
}, 150000)
}
},
mounted () {
//this.user = this.getUser()
this.getUser()
this.fetchData()
},
created () {
//this.user = this.getUser()
this.getUser()
this.getAppointments()
}
}
</script>
I tried some variants with return response.data or data: this.getUser() etc. Obtaining the user in template with {{ user }} works fine but isn't helpful. I don't have any syntax or runtime error from vue/electron-vue
Any idea?

Finally got a solution!
<script>
import Axios from 'axios'
export default {
data () {
return {
appointments: {},
event_counter: 0,
user: 'test'
}
},
methods: {
getUser: function () {
return Axios
.get('http://127.0.0.1:5000/users/get_user')
.then(response => {
this.user = response.data.username
return this.user
})
},
getAppointments: function () {
this.getUser()
.then(data => {
let url = 'http://127.0.0.1:5000/appointments/get_appointments?user=' + data
Axios
.get(url)
.then(response => { this.appointments = response.data })
})
},
fetchData: function () {
setInterval(() => {
this.getAppointments()
}, 150000)
}
},
mounted () {
this.fetchData()
},
created () {
this.getAppointments()
}
}
</script>
The solution was to change the call of the getUser() and retrieve the date in the arrow function block .then(data =>).
The answer of #loan in this Issue give me the hint: How to set variable outside axios get.
Thanks a lot to all.

<script>
import Axios from 'axios-observable'
export default {
data () {
return {
appointments: {},
event_counter: 0,
user: ''
},
computed: {
updatedUrl: {
return `http://127.0.0.1:5000/appointments/get_appointments?user=${this.user}`
}
},
methods: {
forceGetUsername() {
return this.user
},
getUser: function () {
Axios
.get('http://127.0.0.1:5000/users/get_user')
.subscribe(response => { this.user = response.data.username })
},
getAppointments: function () {
console.log(updatedUrl)
Axios
.get(updatedUrl)
.subscribe(response => { this.appointments = response.data })
},
// Below can remain the same
}
</script>
So it seems the url is being cached and not updated once created. So I added new function to ensure the latest value is being returned. Not very ideal.
Added the URL to computed property. If this doesn't work then I am lost as well :(
