class pdf {
static download(data, name,isRandom = true) {
    const link = document.createElement('a')
    let blob = new Blob([data],{type: 'application/pdf;charset=utf-8'});
    link.style.display = 'none'
    link.href = URL.createObjectURL(blob);
  
  
    if (isRandom) {
      let num = ''
      for(let i=0;i < 10;i++){
        num += Math.ceil(Math.random() * 10)
      }
      link.setAttribute('download', name)
    }else {
      link.setAttribute('download', name)
    }
  
    document.body.appendChild(link)
    link.click()
    document.body.removeChild(link)
  }
  
}
export {

export function exportction(url, parameter) {
  return axios({

    params: parameter,
