handleAvatarSuccess (res, file) {
  console.log(res)
  this.dataForm.logo = res.uri
  console.log(this.dataForm.logo)
},
beforeAvatarUpload(file) {
  let _this = this
  const isSize = new Promise(function (resolve, reject) {
    let width = 1920; // 限制图片尺寸为1920X676
    let height = 676;
    let _URL = window.URL || window.webkitURL;
    let img = new Image();
    img.onload = function () {
      let valid = img.width === width && img.height === height;
      valid ? resolve() : reject();
    }
    img.src = _URL.createObjectURL(file);
  }).then(() => {
    return file;
  }, () => {
    _this.$message.error('图片尺寸限制为1920*676')
    return Promise.reject();
  });
  return isSize
}

//上传成功
handleVideoSuccess(res, file) {                               //获取上传图片地址
  this.uploadVideoDisabled = false
  this.videoFlag = false;
  this.videoUploadPercent = 0;
