[Feature Request] Support HTTP/2 requests

[aldaris]

• Insomnia Version: 5.16.6 (5.16.6.2073)
• Operating System: OSX

Details

Currently when Insomnia makes its requests to an HTTPS enabled site, it only uses HTTP/1.1. It would be great if Insomnia would utilize HTTP/2 requests via ALPN.

This should be easy to add, except the node-libcurl project doesn't look like it is built with HTTP/2 compatibility when targeting Windows. See https://github.com/peters/curl-for-windows

I still think this will be good to have eventually 👍

I hope someone is working on this. http2 adoption is getting pretty high and this is a blocking issue for us. I have to disable http2 in our development server and I can't recommend this tool to devOps if it won't work on production.

[gschier]

Just a note: Support for HTTP/2 is already included in the OSX and Linux versions of Insomnia, since they are linked with the nghttp2 library.

I think the only thing that needs to be done is to allow the user to supply the CURLOPT_HTTP_VERSION option

@gschier HTTP/2 does not appear to be working for me.

$ uname -a
Linux laptop 5.0.5-arch1-1-ARCH #1 SMP PREEMPT Wed Mar 27 17:53:10 UTC 2019 x86_64 GNU/Linux

When using the firefox extension RESTClient it works as expected.

However Insomnia is another story. It reacts the same way as Postman.

[WingGithub]

@FallingSnow , there may be some other issue in your use case. Postman works with HTTP2 and the error message I get when I try to use insomnia with http2 looks like this: Error: SSL connect error.

Oops, my bad look like Postman is not using http2, it was falling back to http/1.1

[FallingSnow]

Correct, postman also has an issue open for using http2.

It looks like the error you're receiving with Insomnia has to do with SSL rather than HTTP2.

[FallingSnow]

Good news. The develop branch does in fact support HTTP2 on at least Linux. I just followed the develop instructions to compile and start the app and bingo, it worked!

Any update on this? Does Insomnia support HTTP2 now on OSX?

[crystalfp]

Insomnia is based on libcurl on Windows, correct? So it should be able to access HTTP/2 servers as I do with curl that sets --http2 by default:

"C:\apps\curl\bin\curl.exe" \
--cacert "D:/server/cert/localhost-cert.pem" \
-H "Content-Type: application/json" \
https://localhost:3111/api/project

Hope it helps
