"Only one auth mechanism allowed" error where curl is successful instead

[giacecco]

If curl is successful doing the following:

curl -L -u '***:***' -o file.gz 'https://datafeeds.networkrail.co.uk/ntrod/CifFileAuthenticate?type=CIF_ALL_FULL_DAILY&day=toc-full'

Why doing the same with request makes the server return this error message: "Only one auth mechanism allowed; only the X-Amz-Algorithm query parameter, Signature query string parameter or the Authorization header should be specified"?

var fs = require('fs'),
    request = require('request');
request('https://datafeeds.networkrail.co.uk/ntrod/CifFileAuthenticate?type=CIF_ALL_FULL_DAILY&day=toc-full', { 
    'auth': { 
        'user': '***',
        'password': '***',
        'sendImmediately': true,
    },
}).pipe(fs.createWriteStream('file.gz'));

In case it was useful, the '-L' option in curl is necessary for it to succeed.

Thanks!

It is interesting to add that if I intentionally use a wrong password, I get a "This request requires HTTP authentication (Bad credentials)." error. This means that the authentication is working, at least once, and then the error is returned.

Could it be the same problem in issue #450 ?

Did you ever find a solution to this? I'm seeing the same issue described here and in issue 450 that you linked.

[giacecco]

No sorry medha.

I wrote some of this code, so I'm going to try to find time to look into it this week. In the meantime, a failing test case that doesn't rely on an external server would be extremely helpful.

@nylen any update on this?
@giacecco do you have a test case we can use without an external server?

[nylen]

#1058 should fix this. Still planning to get to that this week.
