help request: how to send mTLS requests in apisix from Lua plugin about apisix HOT 5 CLOSED

could you check the differences in the version of the http library? APISIX uses this: https://github.com/api7/lua-resty-http

from apisix.

Thank you @shreemaan-abhishek for your reply. The Lua plugin is mounted in the APISIX Docker container and executed from there. Looking at the Rockspect from APISIX 3.8 release it looks like the resty-http version is: api7-lua-resty-http = 0.2.2-0

https://github.com/apache/apisix/blob/release/3.8/apisix-master-0.rockspec#L38

from apisix.

yes, the api7-lua-resty-http is a fork of https://github.com/ledgetech/lua-resty-http and it has some missing features.

from apisix.

ok, but how can it be used to issue a mTLS request with APISIX? Does this differ from the upstream resty-http library, or does it contain a bug?

from apisix.

ok I found the issue. Indeed the API of the forked resty-http library differs from the upstream.

so instead of:

local ok, err = httpc:connect {
	ssl_client_cert = cert,
	ssl_client_priv_key = key,
}

The key material of the client should be provided as:

local ok, err = httpc:connect {
	ssl_cert = cert_in_pem_format,
	ssl_key = key_in_pem_format,
}

from apisix.
