使用生命周期钩子onBeforeMount setup(){ const postData = ref([]) onBeforeMount(async () => { const res = await axios.get('http://localhost:3002/postdata') postData.value = res.data }) return { ... postData }

vue3生命周期

// vue2.xexport default { data () { return {} }, methods: { ... }, beforeCreate() {}, created() {}, beforeMount() {}, mounted() {}, beforeUpdate() {}, updated() {}, beforeDestroy() {}, destroyed() {} }   // vue3.x import
