axiosでHttp GET

Home.vue

<template>
<!-- ルートエレメントが1個必要 !!! -->
<div>   
    <button @click = 'clicked'>"GET"</button>
    <hr>
    <p class="cmn">{{ resp_data }}</p>

</div>
</template>

<script lang="ts">
    import { Component, Watch, Vue } from 'vue-property-decorator';
    import axios from "axios";

    @Component({
        components: {
        },
    })
    export default class Home extends Vue {

        public resp_data?: string = "no data.";
        private http;
        
        public created(){
            console.log("[created]")
            this.http = axios.create();
        }

        public clicked(){
            console.log("[clicked]")
            this.get_fb().then();
        }

        public async get_fb() {

            const res = await this.http.get("https://xxxxxxxx.firebaseio.com/person.json");
            console.log(res.data);
            this.resp_data = res.data;

            return res;
        }
    }
</script>

<style>
    .cmn {
        margin: 10px;
    }

APIをComponentで分けた場合(APIボタンモジュール)

Pages/New.vue

<template>
<!-- ルートエレメントが1個必要 !!! -->
<div>   
    <API class="cmn" @emit_clicked='cb_clicked' caption="API"></API>
    <hr>
    <p class="cmn">RESPONSE</p>
    <p class="cmn">{{ resp_data }}</p>

</div>
</template>

<script lang="ts">
    import { Component, Watch, Vue } from 'vue-property-decorator';
    import API from "@/components/API.vue";

    @Component({
        components: {
            API,
        },
    })
    
    export default class New extends Vue {

        private resp_data?:string="";

        public cb_clicked(s:string){
            console.log("[cb_clicked]")
            console.log(s);
            
            this.resp_data=s;
        }    
    }
</script>

<style>
    .cmn {
        margin: 10px;
    }
</style>

 

API.vue

<template>
    <button @click="onClick">{{caption}}</button>
</template>

<script lang="ts">
    import {Component, Prop, Emit, Vue} from "vue-property-decorator"
    import axios from "axios";

    @Component
    export default class API extends Vue {

        private http;
        public resp_data?: string = "no data.";

        @Prop()
        public caption?: string;  

        // 上位にイベント通知
        @Emit()
        public emit_clicked(string){
        }

        public created(){
            console.log("[API]created()")
            this.http = axios.create();
        }
        
        public onClick(){
            this.get_person();
        }

        public async get_person() {

            console.log("[API]get_fb()")
            
            const res = await this.http.get("https://xxxxxxxx.firebaseio.com/person.json");
            console.log(res.data);
            this.resp_data = res.data;
 
            this.emit_clicked(res.data);
            return res;
        }

    }
</script>
