node.js - file upload using fetch API in javaScript -


hi trying upload tar file many days, everytime failing. new js, ui , https req/res domain. environment is: nodejs, javascript backend. reactjs frontend. need upload tar file machine remote server.

here frontend code making fetch request upload file.

export function postxccdf () {   let _headers = {     'accept': 'application/json, application/xml, text/plain, text/html, *.*',     'content-type': 'multipart/form-data; boundary=----webkitformboundaryyemkndsbkjb7qequ'   };    var formdata = new formdata();   formdata.append('type', 'file');   formdata.append('file', 'c:\\mydrive\\rules.zip');    let uri = '/rest/policy';    const options = { method: 'post', headers: _headers, body: formdata };   return fetch(`${_host}${urlprefix}${uri}`, options)     .then(processstatus)     .then(response => response.json());  }

here backend code , expecting tar file receive.

router.post('/policy', function(req, res) {     console.log('hey reached here');     console.log('hemant req',req.body.formdata); // prints hemant req undefined     // dont know how save directory. ??? :( });

my whole idea upload tar file server located @ remote location. have tried lot many other ways, nothing seems help.

the body-parser module handles json , urlencoded form submissions, not multipart (which case if you're uploading files).

for multipart, you'd need use connect-busboy or multer or connect-multiparty (multiparty/formidable used in express bodyparser middleware).
