FileData.content_typestringThe content type that will be specified in the multipart request.
FileData.filenamestringThe filename that will be specified in the multipart request.

Example

import { sleep } from 'k6';
import { md5 } from 'k6/crypto';
import http from 'k6/http';


const binFile = open('/path/to/file.bin', 'b');


export default function () {
  const f = http.file(binFile, 'test.bin');
  console.log(md5(f.data, 'hex'));
  console.log(f.filename);
  console.log(f.content_type);
}
