Vue3 route.query 为空

Question

试图将路由查询传递给axios 请求，但它是空的.. route.query在挂载时返回空。 route.queryreturns {"filter[city]": "Vilnius" } 在 axios 中 then nextTick 不能解决问题。有什么建议吗？

import { ref, onMounted, nextTick } from 'vue';
import axios from 'axios';
import { initMap } from '../../functions/useMap';

import { useRouter, useRoute } from 'vue-router';

export default {
    setup() {
        const router = useRouter();
        const route = useRoute();

        onMounted(() => {
            console.log(route.query);  // log is {}
            fetchApartments();
        });
    
        function fetchApartments() {
            console.log(route.query); // log is {}
        
            axios.get('/api/apartments').then(response => {
                console.log(route.query); // log is { "filter[city]": "Vilnius" }
            });
        }
    }
}

像这样更新你的代码：

...
import { computed } from 'vue'
...

在 setup() 内部

const route = useRoute();
const query = computed(() => route.query)

这里缺少的部分是计算属性。
