http-dialer

Demonstrates an http client in go that dials an http server, also in go, over Iroh using the standard library's http.Client.

This example builds on echo-endpoint and does away with any external program dependencies; everything is done in go.

Build a binary

go build --ldflags '-linkmode external -extldflags=-static -s -w' ./http-dialer.go

If you run into glibc incompatibility, you can compile with zig/musl.

CC="zig cc -target x86_64-linux-musl -lunwind" \
CGO_ENABLED=1 \
CGO_LDFLAGS="-static" \
GOOS=linux GOARCH=amd64 \
go build -v -a -ldflags '-extldflags "-static"' ./http-dialer.go

Terminal 1 (http server)

go build ./http-dialer.go
./http-dialer 
// outputs, among other things, an endpoint ticket you need to provide in Terminal 2

Terminal 2 (http client)

Send an HTTP POST request to our http server in Terminal 1 over Iroh using the program http-client from the client/ sub-directory of this example:

go build ./client/http-client.go
./http-client --address <endpoint from Terminal 1> hello hello

You should see the string "hello hello" echoed back out to you, prefixed with the public key of the Iroh endpoint establishing the connection in Terminal 1.

If you run the program again, you will see another prefixed public key. This is because http-client creates a new Iroh identity each time it runs.
