var data = JSON.stringify(json) 
//encodeURIComponent解决中文乱码
let uri = 'data:text/csv;charset=utf-8,\ufeff' + encodeURIComponent(data);
//通过创建a标签实现
let link = document.createElement("a");
link.href = uri;
//对下载的文件命名
link.download = `${
      
      this.downloadPersonName || '人物库-优图库'}.json`;
document.body.appendChild(link);
link.click();
document.body.removeChild(link);
