读取地址返回的json，修改后上传json文件

// 上传首页数据设置、主题js文件
export function uplaodTheme(data, fileName) {
  var dataString = JSON.stringify(data);
  var blob = new Blob([dataString], {type: "text/plain;charset=utf-8"});//将数据转换为blob对象
  let themeFile = new File([blob],fileName,{lastModified:Date.now()})//blob转file
  // var a = document.createElement(‘a‘)
  // a.href =URL.createObjectURL(themeFile)
  // document.body.appendChild(a)
  // a.click()
  // document.body.removeChild(a)
  var formData = new FormData();
  formData.append("file", themeFile);
  postAjax(`${url}${filesUrl}/system/config/upload`,formData).then(res=>{
      console.log(‘upload-------‘, res)
  })
  console.log(‘themeFile‘, themeFile)
}

import {uplaodTheme} from "../../../../assets/js/base";

// 上传文件
uplaodTheme(this.$store.state.indexData,‘theme.json‘);

拉去地址数据，直接用get请求访问地址
