</script>
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);
});
