repetedly call a axios.get to display data from endpoint - vue.js

Question

I working on backend written in flask that returns REST API for various task, one of which is to request deployment,
Then log gets filled in the database. So I have created another REST API endpoint to return log message for the specific request id. Now what I want is to once the showStatus is true the log_url used by axios.get should be constantly hitting and retrieving data from the backend endpoint retrieving data after 30 seconds. and show it in the show below as statusMessage.
<script>
import Vue from 'vue';
import axios from "axios";
import Multiselect from "vue-multiselect";
Vue.component("multiselect", Multiselect);
export default {
name: 'SelectServices',
data: function() {
return {
selectedService: "",
services: [],
updateExisting: "",
showStatus: false,
statusMessage : ""
}
},
mounted() {
console.log("running script");
},
methods : {
selectServiceToDeploy: function(){
// alert("micro services");
},
deploySelected: function(){
this.showStatus = true ;
// animate open the status window.
$("#status_update").animate({height: '500'})
var url = "http://localwebsite.com:5060/services/request_deploy";
axios.post(url)
.then(response => {
if (typeof response.data.reason != "undefined"){
alert("Recieved Status: " + response.data.status + ",\nReason: " + response.data.reason);
}
var req_id = response.data.result.request_id;
this.statusMessage = "Initiating deployment of Services for Request ID: " + req_id ;
var log_url = "http://localwebsite.com:5060/services/get_logs/" + req_id;
axios.get(log_url)
.then(response => {
if (response.data.status == "success"){
this.statusMessage = this.statusMessage + response.data.logs;
}
})
})
.catch((err) => {
console.log("Error happened: " + err.request.message);
alert(err);
return Promise.reject(err);
})
console.log(url);
console.log(log_url);
}
}
}
based on the above logic I have written in vue it successfully request for deployment but the logs don't get printed in the UI! how can I constantly retrieve data from http://localwebsite.com:5060/services/get_logs/" + req_id after every 30 seconds.

You can do something in the mounted hook:
mounted(){
this.interval = setInterval(() => {
axios.get(this.my_url).then(res => { /* do something */});
}, 30000 );
},
data(){
return {
interval: undefined,
my_url: undefined
}
}
setInterval is a javascript function that allow you to run a function every predefined milliseconds. You can cancel it later with the following command: clearInterval(this.interval). You can also change my_url when you want :)
