创建一个 文件getOssClient

import { getOssSetting } from "@/api/common";
import Vue from "vue";
import { getCookies, getLocal } from "@/utils/auth"; // get token from cookie
export async function getStsToken() {
  //从后台获取stsToken
  if (getCookies("token")) {
    const res = await getOssSetting();
    if (res.code == 200) {
      Vue.prototype.$ossClient = getClient(res.data);
    }
  }
 
}
export function getClient(data) {
  const Minio = require('minio');

getStsToken()

上传组件中使用 打开上传就会拿到key
