VueJS HTTP request error 500 Handling

问题

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?

Example Request:

this.$http.get('people', { params }).then(({ data }) => {

            this.setFetching({
                fetching: false
            })
        })

回答1:

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);
      })
  }
});
