This Go application serves requests using only the HTTP/2 cleartext (h2c) protocol (it does not support upgrading from HTTP/1.1).
It is provided for testing end-to-end HTTP/2 capabilities on Cloud Run.
Click this button:
Alternatively, you can use the gcloud
SDK:
gcloud beta run deploy http2-test --use-http2 --source=.
Cleanup: Remove the http2-test
Service you deployed from Cloud Run
using the Cloud Console.
-
Check out this repository and navigate to this directory
-
Start the server locally:
go run .
-
After the server starts, make a request using
curl
and use--http2-prior-knowledge
to prevent upgrading from HTTP/1.1 (which is intentionally not supported by this program).curl -v --http2-prior-knowledge localhost:8080
Note: If you have deployed on Cloud Run, you can replace
localhost:8080
with your Cloud Run service URL. -
The
curl
output should indicate HTTP/2 is used:< HTTP/2 200 < content-type: text/plain; charset=utf-8 < content-length: 32 < date: Fri, 08 Jan 2021 18:13:06 GMT This request is served over HTTP/2.0 protocol!
Since this server intentionally doesn't support upgrading from HTTP/1.1,
performing the same query without the --http2-prior-knowledge
option makes
curl to use HTTP/1, which fails as expected.
