 <a-upload name="file"  accept=".pdf,.doc,.docx" :before-upload="beforeUpload">
            <a-button>
              <a-icon type="upload" /> 选择 </a-button>
          </a-upload>

import  mammoth from 'mammoth';

 beforeUpload(file){
    if (!file) {
      return;
    }
    console.log(file+"input")
    let fileType = ['.docx','.doc']
       let { name } = file;
       let nameLen = name.length;
      let hzIndex = name.lastIndexOf(".");
      //获取后缀名
      let hz = name.substring(hzIndex, nameLen);
      if (!fileType.includes(hz)) {
        this.$message.warning({
          message: "注意:只支持docx格式的文档",
        })
        return false
      }
      console.log(hz);
      var that = this;

    
      var reader = new FileReader();
      reader.readAsArrayBuffer(file); 
      reader.onload = function (loadEvent) {
                console.log(loadEvent.target.result);
                var arrayBuffer = loadEvent.target.result;
               mammoth.convertToHtml({ arrayBuffer: arrayBuffer })
                    .then(
                      function (resultObject) {
                        setTimeout(function(){

                        }, 300);
                        console.log(resultObject.value);//这个就是我们得到的html
                           }).done();
                
            };
