Support HTTPS

[boekkooi-lengoo]

Good day,
I'm currently using the opentelemetry plugin in APISix in combination with Elastic APM which is served over https.
Sadly I can't seem to get this to work as the address gets prefixed with http:// in the http_client.

This results in the following error.

2023/01/25 10:55:29 [error] 51#51: *5451 [lua] http_client.lua:46: do_request(): request failed: Client sent an HTTP request to an HTTPS server.
, context: ngx.timer, client: 10.20.0.68, server: 0.0.0.0:9443

Is it possible to add support for https or at least only prefix the address when it contains no protocol?

Thanks in advance.

Related to https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/protocol/exporter.md#configuration-options and the env var OTEL_EXPORTER_OTLP_ENDPOINT

I will try to implement this feature.

@boekkooi-lengoo Do you need config ssl_verify = false, see https://github.com/ledgetech/lua-resty-http/blob/2af9925acf5cbb5b387539cd4463552ebbd5efee/lib/resty/http_connect.lua#L30

Hey @yangxikun,
Thank for for having a look at this issue.
I think allowing the user to configure ssl_verify would be great, however in my case I don't need it 😄
