Header name must be a valid HTTP Token (colon in header)

Summary

I got the error [TypeError: Header name must be a valid HTTP Token [":authority"]]

Simplest Example to Reproduce

var request = require('request');

var options = {
    url: '----',
    headers: {
        ':authority': 'www.site.com',
        ':method': 'GET',
        ':scheme': 'https',
        'referer': 'https://site.com',
        'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.78 Safari/537.36'
    }
};

function callback(error, response, body) {
    if (!error && response.statusCode === 200) {
        console.log(body);
    }
    if (error) {
        console.log(error);
    }
}

request(options, callback);

Expected Behavior

I want to execute request with “:authority” header

Current Behavior

It doesn’t work.

Possible Solution

Add a flag use raw headers and pass headers as is.

Context

Plain nodejs.

Your Environment

software	version
request	2.81.0
node	v5.10.1
npm	5.3.0
Operating System	mac os 10.12.6

@Freyert I don’t agree that this is a solution because it is not guaranteed that this API is under our control. At least this should be configurable. Many of us will want to be able to request APIs that do not adhere perfectly to IETF standards.

[Freyert]

Your API has to be fixed:

3.2.  Header Fields

   Each header field consists of a case-insensitive field name followed
   by a colon (":"), optional leading whitespace, the field value, and
   optional trailing whitespace.
