我正在尝试获取当前用户的令牌以获取检索数据，如下所示：

async getUser() {
    const config = {
                headers: {
                    'Accept': 'application/json',
                    'Authorization': 'Bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJSUzI1NiJ9.eyJ...'
                }
            }
  await this.axios
    .get("/api/auth/testapi", config)
    .then((response) => {
      this.user = response.data;
    })
    .catch((error) => {
      console.log(error);
      this.user = [];
    });
},

如何设置“Authorization”头以自动获取已验证用户的当前令牌？
我尝试了本地存储，如下所示：

async getUser() {
    const token = localStorage.getItem('access_token');
    const config = {
                headers: {
                    'Accept': 'application/json',
                    'Authorization': `Bearer ${token}`
                }
            }
  await this.axios
    .get("/api/auth/testapi", config)
    .then((response) => {
      this.user = response.data;
    })
    .catch((error) => {
      console.log(error);
      this.user = [];
    });
},

但效果不太好
有什么问题吗？
最新消息：
app.js:

require("./src/main.js");
import VueAxios from "vue-axios";
import axios from "axios";
Vue.use(VueAxios, axios);

if (localStorage.has("access_token")) {
axios.defaults.headers.common["Authorization"] =
"Bearer " + localStorage.getItem("access_token");
}

loginSuccess(accessToken) {
localStorage.setItem('access_token', accessToken);
window.location.href = '/home';
}

if结束后出现问题

';' expected.
