Vue-resource: 请问如何abort()未完成的请求？

[Eosxx]

有时候一些操作会导致在请求相同的内容时，发送多个http请求。

我该如何终止之前某一个未完成的http请求？

Abort a previous request when a new request is about to be sent. For example when typing in a autocomplete input.

{
  // GET /someUrl
  this.$http.get('/someUrl', {

    // use before callback
    before(request) {

      // abort previous request, if exists
      if (this.previousRequest) {
        this.previousRequest.abort();
      }

      // set previous request on Vue instance
      this.previousRequest = request;
    }

  }).then((response) => {
    // success callback
  }, (response) => {
    // error callback
  });
}

}

取消后会执行 error callback ，有办法呢判断到底是报错还是取消吗？（取消后不希望执行 error callback） 谢谢啦
