Cannot upload multiple files without "[]"

Summary

I tried to upload multiple files using requestjs but only the last file in the array was uploaded unless I added “[]” after the key.

Simplest Example to Reproduce

var formData = {
  attachments: [
    fs.createReadStream(__dirname + '/attachment1.jpg'),
    fs.createReadStream(__dirname + '/attachment2.jpg')
  ]
};
request.post({url:'http://service.com/upload', formData: formData}, function optionalCallback(err, httpResponse, body) {
  if (err) {
    return console.error('upload failed:', err);
  }
  console.log('Upload successful!  Server responded with:', body);
});

Expected Behavior

Server should receive two files.

Current Behavior

Only the last file in the array was uploaded.

Possible Solution

Now I could only change the key from “attachments” to “attachments[]” to avoid this problem. But I think this is a bug because the doc says it is ok to use “attachment” as the key to upload multiple files.

software	version
request	2.81.0
node	6.11.2
npm	3.10.10
Operating System	macOS

I ended up having to use the “advanced method” in https://github.com/request/request#forms.

var r = request.post('http://service.com/upload', function optionalCallback(err, httpResponse, body) {...})
var form = r.form();
form.append('file[]', fs.createReadStream(__dirname + '/file1.jpg'));
form.append('file[]', fs.createReadStream(__dirname + '/file2.jpg'));
r();

Would be nice to just be able to pass an Array or something.
