The `page.setCookie` method should also accept raw cookies

Steps to reproduce

Tell us about your environment:

• Puppeteer version: 1.12.2
• Platform / OS version: macOS 10.14.3
• URLs (if applicable):
• Node.js version: 10.15.0

What steps will reproduce the problem?

await page.setCookie('foo=bar');

What is the expected result?

It works.

What happens instead?

It doesn’t.

Not being able to set raw cookies is very inconvenient. There are multiple situations where it would be useful:

1. Copy-pasting cookies from DevTools.
2. Accepting cookies as user input in a command-line tool.
3. Getting cookies from a server request, for example in Express where you read the cookie header, and then pass them to Puppeteer.

Yes, I could find an npm package for this, but the ones I found are not very good (tough-cookie included). I also think it’s such a basic thing that a big percentage of Puppeteer users will need, that it should be supported by Puppeteer natively.

Hello, there googler!!

I used the ‘EditThisCookie’ extension that has a nice feature export, it will export cookies as JSON, in a perfect format so the puppeteer can consume without any transformation.

const puppeteer = require('puppeteer');
const cookies = require('./cookies.json')

async function main() {
 const browser = await puppeteer.launch()
 const page = await browser.newPage()
 await page.setCookie(...cookies)
	
 await page.goto('https://www.reddit.com')
 await page.screenshot({ path: 'reddit.png' })
 await browser.close()
}

main().catch(console.error)

@sindresorhus in this case page.evaluateOnNewDocument would probably work as a workaround.

But I guess what you really want is a browserContext.setCookie(url, 'foo=bar') method.
