Vue 攔截器對token過期處理方法

Vue.http.interceptors.push(function (request, next) {//攔截器設置請求token

 // sessionStorage.getItem("tokenUrl");
 request.headers.set('token', sessionStorage.getItem("tokenVal"));
 if (request.url.indexOf(url) === -1) {
 request.url = url + request.url;
 }
 // continue to next interceptor
 next(function (response) {
 // ..if(response.body.code=="失敗碼")
{
parent.location.href="登錄頁面路徑" rel="external nofollow" ;
}.
 // 請求發送后的處理邏輯
 // ...
 // 根據請求的狀態，response參數會返回給successCallback或errorCallback
 return response
 });
});
