Support proxy network

[hanguokai]

To use proxy network, like http(s) or socks5, I use http_proxy and https_proxy environment variable that are supported by many tools. Currently, clasp can't work in proxy environment, for example clasp login and clasp clone.

I'm not sure what this would change would entail.
Can you be more specific about repro steps, some links, and a more detailed proposal on what commands this would be needed for?

It looks like this request would want to add something like:
--proxy "socks5://127.0.0.1/"
to every command.

Yes, clasp need to add --proxy option, like youtube-dl, curl, gcloud, npm, git, etc.

http_proxy environment variable is the same meaning as --proxy, but detect by command if no --proxy option specified.

I am using socks5 protocol, there are others like http, https.

@hanguokai Can you add proxy rule to the URL googleapis.com so that every googleapis.com request is proxied?

Pull requests are welcome.
I'm closing this since I don't see much demand for this feature. Will reopen if there's demand or more discussion.

I would also like to see a proxy option.
Since I'm developing behind a corporate proxy I always need to activate my smartphone hotspot.

I'm using clasp from a censored internet where all things Google are blocked and need the proxy feature. Using proxy environment variables doesn't work.

Why doesn't using proxy environment variables not work? Every request goes through http://googleapis.com/.

Does every application you use require a proxy feature?

[hanguokai]

Aha, please look at the same issue for firebase command line tool firebase/firebase-tools#155 . Nearly 2 years and 81 comments! Under certain conditions, people can't connect internet directly. That's it.

@grant Yes, all blocked domains and IP requires a VPN or proxy. It's very standard in places like China.

Unfortunately G Suite and many of Google's services are blocked in China. I can't solve that issue. I'm guessing the Firebase tool would probably prefer to not be blocked too to solve that linked issue.

I don't understand why environment variables don't work, do you really need every single tool you use to implement a custom --proxy option?

Underneath it all, we use googleapis. It supports a proxy (HTTP_PROXY, HTTPS_PROXY). Does that not work?

To implement this feature, I'd need:

• A reasonable number of people to request and use the proxy feature (👍 the issue)
• A design doc for this feature.
• Ideally a pull request with an initial implementation.

To be honest, I have no use for this feature and still don't understand why you can't use a proxy elsewhere in the tech stack.

Hello, I'm running through the same problem. I tried setting up my user variables with proxy settings, and I'm still receiving the error below:
Error retrieving access token: Error: connect ETIMEDOUT 172.217.18.170:443

Is there a workaround for this issue?

[grant]

I'm in favor of adding a proxy option, but to be honest, I don't know how to run a proxy and I don't know why env variables don't work like in the googleapis README:

export HTTP_PROXY=http://localhost:3128
export http_proxy=http://localhost:3128
export https_proxy=http://localhost:3128
export HTTPS_PROXY=http://localhost:3128

I did a bit more research.

• If someone wants to try this, add a proxy variable to this line of code: https://github.com/google/clasp/blob/master/src/auth.ts#L40
  Then rebuild clasp and test it out, and it works, that'd be awesome. Then I can update clasp to include this proxy param.
• If someone (@hanguokai, @nepsilon) describes exact steps on how to download a proxy, see the error in clasp using some tool, I'll try to reproduce the problem and create a solution.
• If you need help with a pull request, or building clasp, LMK too.

This is the most upvoted issue, and it looks like user variables doesn't work, so I'm in favor of support this feature in clasp, but I'll need some help for this one.
