I have a requirement to pass List<Map<String, String>> as a parameter for REST GET API. I need to know how this can be passed from Postman or similar tool.

I tried to set it as a BODY for a GET API, it is giving me errors.

var http = require('http');
var formidable = require('formidable');
var fs = require('fs');

http.createServer(function(req, res) {
  if (req.url == '/fileupload') {
    var form = new formidable.IncomingForm();
    form.parse(req, function(err, fields, files) {
      var oldpath = files.filetoupload.path;
      var newpath = 'D:/nodejs/images/' + files.filetoupload.name;
      fs.rename(oldpath, newpath, function(err) {
        if (err) throw err;
        res.write('File uploaded and moved!');
        res.end();
      });
    });
  } else {
    res.writeHead(200, {
      'Content-Type': 'text/html'
    });
    res.write('<form action="fileupload" method="post" enctype="multipart/form-data">');
    res.write('<input type="file" name="filetoupload"><br>');
    res.write('<input type="submit">');
    res.write('</form>');
    return res.end();
  }
}).listen(3000);
