这是在 config 目录下的 index.js 文件中设置的 proxyTable

proxyTable: {
      'api': {
        taget: "http://localhost:8080",
        pathRewrite:{
          '^/api': '/static/mock'
        }
      }
    },

City.vue 中的 逻辑代码

<script>
    import axios from "axios";
    import CityHeader from "./components/Header";
    import CitySearch from "./components/Search";
    import CityList from "./components/List";
    import CityAlphabet from "./components/Alphabet";
    export default {
        name: "City",
        components: {
            CityHeader,
            CitySearch,
            CityList,
            CityAlphabet
        },
        methods: {
            getCityInfo(){
                axios.get("/api/city.json").then(this.handleGetCityInfoSucc)
            },
            handleGetCityInfoSucc(res) {
                console.log(res);
            }
        },
        mounted() {
            this.getCityInfo();
        }
    }
</script>

换成 axios.get("/static/mock/city.json").then(this.handleGetCityInfoSucc) 就没问题
