How to change a user agent string?

[ondrejmirtes]

Is there a way to simulate a different user agent string with Chromy? My usecase is that I want the application to recognize when Chromy is doing the request so that it can react to that, via a user agent string.

Hi @ondrejmirtes,

as far as i know, there are two way to change user agent:

1. pass the --user-agent flag to chromeFlags options when creating chromy instance.

2. use custom device. (sorry currently it's undocumented.)

Chromy.addCustomDevice({
    name: 'iPhone6'
    width: 750,
    height: 1334,
    deviceScaleFactor: 2.0,
    pageScaleFactor: 1.0,
    mobile: true,
    userAgent: 'Mozilla/5.0 (iPhone; CPU iPhone OS 9_1 like Mac OS X) AppleWebKit/601.1.46 (KHTML, like Gecko) Version/9.0 Mobile/13B143 Safari/601.1',
})
const chromy = new Chromy()
chromy.emulate('iPhone6')
             .goto(url)
             .end()

@ondrejmirtes sorry, I had forgot another way.

3. use .userAgent()

const chromy = new Chromy()
chromy.userAgent('Mozilla/5.0 (iPhone; CPU iPhone OS 9_1 like Mac OS X) AppleWebKit/601.1.46 (KHTML, like Gecko) Version/9.0 Mobile/13B143 Safari/601.1')
             .goto(url)
             .end()
