1. 引用t mammoth（先install）

import mammoth from "mammoth";

2.上传文件后，处理文件

getReferenceContent(result) {
      let text = result.value;
      // 将解析出部分文本
      const number= text.indexOf(xxx：");
      if(number>0){
          let content=text.substring(number+5,text.length-1);
      this.referenceContent=content;
      } 
    },
    readFileInputEventAsArrayBuffer() {
          let that = this;
            var file = this.fileInfo.file;
            var reader = new FileReader();
 
            reader.onload = function (loadEvent) {
                console.log(loadEvent);
                var arrayBuffer = loadEvent.target.result; 
                mammoth.extractRawText({ arrayBuffer: arrayBuffer }) 
                    .then(res => that.getReferenceContent(res));
            };
            reader.readAsArrayBuffer(file);
    }
