vue 移动端今天写了一个根据后台传过来的http状态码，来实现跳转error页面

Vue.prototype.$onError = function (error) {
var error_msg = '网络错误';
var toastFlag = true;
switch (error.errorCode) {
case 401:
error_msg = '请先登录';
break;
case 500:
error_msg = '服务器错误';
break;
case 504:
error_msg = '网络超时'
break;
case 20000:
toastFlag = false;
this.$router.push({path: 'invalidIdentity'});
break;
}
if(toastFlag){
this.$Toast({
message: error_msg,
position: 'bottom',
duration: 2000,
callback: () => {
this.$router.push({path: 'error'});
}
})
}
}

siteService.sales(this.time).then(res => {
vm.salesInfo = res.data;
vm.details = vm.salesInfo.details;
vm.saleSum = vm.salesInfo.saleSum;
vm.time = vm.salesInfo.time;
}, err => {
this.$onError(err);
});
