axios取消请求

Axios 使用 cancel token 取消请求

1、先在axios请求中加上cancelToken

import request from '../utils/request' // 配置过的Axios 对象
import axios from 'axios' 

export function getDetail(params, that) { 
  return request({
    url: '/api/indexlineage/detail', 
    method: 'get',
    params: params,
    cancelToken: new axios.CancelToken(function executor(c) { // 设置 cancel token
      that.source = c;
    })
  })
}

2、在组件中调用

import { getDetail} from "../api";
export default {
    data() {
      return {
        source: null
      }
    },
    methods: {
      cancelQuest() {
        if (typeof this.source === 'function') {
          this.source('终止请求'); //取消请求
        }
      },
      getDetailData(val) {
        this.cancelQuest() // 请求发送前调用
        let params = {
            id: '1',
        }
        getDetail(params, this).then(res => {
              console.log(res)
            }
        )
    }
}
