vue实现axios图片上传功能

import axios from "axios";
import config from "@/config";
import router from "@/router";
import validate from "@/util/validate";
import Qs from "qs";
const request = axios.create({
 baseURL: config.hostUrl,
 timeout: 52000,
 transformRequest: [
  (data) => {
   return data instanceof FormData ? data : Qs.stringify({ //此处的data类型判断为重要点，
    ...data
   });
  }
 ]
});
request.interceptors.request.use( //请求拦截
 config => {
  return config;
 },
 error => Promise.error(error)
);

request.interceptors.response.use(// 响应拦截器
 async function (res) {
   if (res.status === 200) {
    return Promise.resolve(res.data);
   } else {    
    return Promise.reject(res.data);
   }
  },
  async function (error) {
   const {
    response
   } = error;
   if (response) {   
    return Promise.reject(response);
   } else {    
   }
  }
);
export default request;

async upImgs(files) { // 我的相册图片上传    
    return (await request.post('/basis/uploadFile', files)).response
     },

async file_up(event) {
   //图片预览
   try {
    let res = null;
    this.file = [...event.target.files];
    for (let i = 0, f; (f = this.file[i]); i++) {
     if (i >= 8 || this.imgs.length >= 8) {
      return;
     }
     let fileImg = new FormData();
     fileImg.append("file", f);
     res = await this.$api.upImgs(fileImg); //这里是调用api处， 此处为多图上传，供参考
     if (res.result) {
      this.imgs.push(res.result.absoluteFilePath);
     }
    }
   } catch (err) {
    this.$toast({
     message: err.message,
     duration: 1200
    });
   }
  }
