在main.js设置全局http地址：
Axios.defaults.baseURL = 'http://XXX.XXX.XX.XXX:9001'; Axios.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded';
在main.js中设置header中token值：
// 添加请求拦截器 Axios.interceptors.request.use(function(config) { config.headers.access_token = "add7c097-f12b-40fe-8e48-6fe1f2120fa5"; // config.headers.Authorization = localStorage.token; //将token设置成请求头 console.log("请求============" + config); // 在发送请求之前做些什么 return config; }, function(error) { // 对请求错误做些什么 return Promise.reject(error); });
数据刷起来！
