node.js--Uploading Files asynchronously

Front Code

Submit () {    varthis. $refs. Fileupload.files[0];     var New FormData ();    Formdata.append ("file", file);    Formdata.append (this. username);    Formdata.append (this. password);    Axios.post ("http://127.0.0.1:3000", FormData). Then (res = = {    console.log (res);    });

Background code

 App.use (function   (req, res) { var  form = new   Formidable.    Incomingform (); Form.uploaddir  = Path.join (__dirname, ' uploads '  function   (err, fields, files) {Fs.rename (Files.file.pat H, Path.join (__dirname,  ' uploads ', files.file.name), function   (err) { if  (! return  res.end (' OK '  });} )

Attention

• The front end uses Formdata to get the file data, which is the interface provided by the XHR asynchronous upload file
• Background code if you do not use formidable this package, it is very troublesome to handle the incoming binary data yourself.
