HTTP proxy authent with fetch #273

Open nocquidant opened 6 months ago

nocquidant commented 6 months ago

Hi, sometimes I need to attach one of my Lambdas to a VPC to access private ressources like ALB... And then, I have to specify an HTTP proxy to be able to access the Internet (security requirement). But as far I as know, fetch doesn't support HTTP proxy with authentication out of the box. Do you have some guidelines here to make this use case work? Thanks! --nick

It would be nice if variables: HTTP_PROXY, HTTPS_PROXY and NO_PROXY could be supported out of the box. As bun did: https://github.com/oven-sh/bun/issues/1440 (or Deno) My understanding is that it is not supported yet in Node: https://github.com/nodejs/undici/issues/1650 Would import the unidici dependency work (and configure the proxy agent)?

Hi @nocquidant. So you wan't fetch to route request via a proxy configured via HTTP(s)_PROXY? How would you configure auth? Meanwhile, can you use something like s_client to work around that?

nocquidant commented 6 months ago

Hi, thanks for your response! The HTTP(s)_PROXY URL supports credentials: http_proxy=http://user:password@proxy:port/ Humm, so I guess s_client would be installed via layer? Not very convenient and doesn't the layer affect cold starts?

Thanks, we will add this!

Hi, any chance of implementing this in near future? I 'll need it for my next project. Thanks (just asking)
