问题描述
我遇到这个问题,我向API发出HTTP请求,如果出现错误(特别是错误500),JS就会中断或进入无限循环,我应该关闭窗口并重新打开页面。我需要的是一个弹出的消息,并以非常通用的方式解释发生了什么。我该怎么处理这种错误呢?
I am having this problem where I make HTTP Request to the API and in case of error ( specially error 500) the JS just breaks or goes into infinite loop and I should close the window and re-open the page. What I need is a message to pop up and in very generic way explain what happened. How should I handle this kind of error any ideas?
示例请求:
this.$http.get('people', { params }).then(({ data }) => { this.setFetching({ fetching: false }) })推荐答案
然后 接受第二次回调以处理错误。除了 .then 之外,您还可以提供 .catch 来处理更严重的故障。
then accepts a second callback to handle errors. You can also supply a .catch in addition to a .then to handle more severe failures.
new Vue({ el: '#app', data: { fetching: true }, mounted() { this.$http.get('people') .then(() => { this.setFetching({ fetching: false }) }, (err) => { console.log("Err", err); }) .catch((e) => { console.log("Caught", e); }) } });
