axios 实现取消请求中的接口

import axios from 'axios'
  
  export default {
    data() {
        return {
            serverSource: ''
        }
    },
    methods: {
      getData() {
        console.log('获取数据')
        const serverSource = axios.CancelToken.source()
        const params = {
          cancelToken: serverSource.token
        }
        this.serverSource = serverSource
        
        axios.get('/apis', params)
        .then(data => {
          console.log(data);
        })
        .catch(err => {
          console.log(err);
        });
      },
      cleanFn() {
        console.log('释放请求')
        this.serverSource.cancel('cancel http')
      }
    }
  }
