zipEntries.js?4c22:149 Uncaught Error: Can't find end of central directory : is this a zip file ? If it is

使用axios请求一个express的静态文件地址，请求结果是blob类型，然后使用 filereader 读取blob中的buffer，然后就报错了

this.axios({
           method: "get",
           url: "http://127.0.0.1:3000/demo文档.doc",
           responseType: "blob"
       }).then(r => {
           let res = r.data;
           let file = new FileReader();
           file.onload = function(e){
               let buffer = e.target.result;
               mammoth.convertToHtml({arrayBuffer:buffer}).then(r=>{
                   console.log(r);
               }).done();
           }
           file.readAsArrayBuffer(res);

It looks like you’re trying to use a .doc file, which isn’t supported.

Only support .docx, use .doc will report this error.
