Please help me pass it correctly to this section of code (vue.js) :

methods: {
      setId () {
        this.dataSecretId = this.$route.params.id;
      },
      goTo(route, id){
        if (this.$route.path === route){
          return
        }
        router.push({
          path: route,
          params: { dataSecret: id}
        })
      },
      fillData () {	
        this.ScoreDonutPercents = 79;

        this.ClassifiedHighLevelScoreValue = 37;
        this.ClassifiedHighLevelScoreMax = 99;

        this.TablesHighLevelScoreValue = 30;
        this.TablesHighLevelScoreMax = 72;

        this.AnalyticsHighLevelScoreValue1 = 50;
        this.AnalyticsHighLevelScoreValue2 = 80;
        this.AnalyticsHighLevelScoreValue3 = 18;

        this.AnalyticsMax = 3456;
        this.AnalyticsHighLevelScoreMax1 = this.AnalyticsMax;
        this.AnalyticsHighLevelScoreMax2 = this.AnalyticsMax;
        this.AnalyticsHighLevelScoreMax3 = this.AnalyticsMax;

      },
      getData () {
        let self = this;
        HttpService.methods.post(`/results/`+this.dataSecretId)
          .then(function (response) {
            console.log(response.data.data)
            // self.dataSecrets = response['data']['data'];
          })
          .catch(function (error) {
            console.log(error);
          })
      }
    }

Answer 1

test() {
let self = this;
HttpService.methods.post('/api/metrics/'+ this.dataSecretId)
.then(response => {
console.log(response.success)
self.dataSecrets = response['data']['data'];
} )
.catch(error => {
console.log(error);
})
}
