VueJS HTTP请求错误500处理 [英] VueJS HTTP request error 500 Handling

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);
      })
  }
});
