proxy not works with https sites

[denis-marecky]

400 bad request when using proxy & trying to send https requests. http requests works fine

[ronag]

Please provide a reproducible example

[denis-marecky]

async function test() {
const { Client } = require('undici')

const serverUrl = https://facebook.com:443
const proxyUrl = http://122.155.165.191:3128

const client = new Client(proxyUrl)
client.on('connect', () => {
console.log(Connected)
})
client.on('disconnect', arg => {
console.log(Disconnected: ${arg})
})

const response = await client.request({
method: 'GET',
path: serverUrl,
})

console.log(Status: ${response.statusCode})

response.body.setEncoding('utf8')
let data = ''
for await (const chunk of response.body) {
data += chunk
}
console.log(data)

client.close()
}
test()

Running that script I am getting:

It seems that host is down.

It seems that proxy goes down. I took some public to not share my own private. Try any other public proxy currently alive. We test that on few servers

I do not have a public proxy. I would recommend you to send a PR/build an example similar to https://github.com/nodejs/undici/blob/main/test/proxy.js.

Moving to discussions as this seems like a help request
