[I] bug: forward-auth plugin doesn't work properly with POST method. [apisix]
suryaprabhakark opened a new issue, #11020:
URL: https://github.com/apache/apisix/issues/11020
### Current Behavior
forward-auth plugin doesn't work if the request is POST and authservice api is GET. Its happening due to forwading the POST method request headers like content-type and expect. Moved these headers only if authserver api is also POST.
### Expected Behavior
It should work without any problems, based on the authserver method, appropriate headers should be passed.
### Error Logs
`2024/03/09 15:35:28 [error] 51#51: *13215177 [lua] forward-auth.lua:134: phase_func(): failed to process forward auth, err: timeout, client: 10.117.4.40, server: _, request: "POST /post HTTP/1.1", host: "apiv2.ninjacart.in", referrer: "http://localhost:4000/"
2024/03/09 15:35:28 [warn] 51#51: *13215177 [lua] plugin.lua:1159: run_plugin(): forward-auth exits with http status code 403, client: 10.117.4.40, server: _, request: "POST /post HTTP/1.1", host: "apiv2.ninjacart.in", referrer: "http://localhost:4000/"
10.117.4.40 - - [09/Mar/2024:15:35:28 +0000] apiv2.ninjacart.in "POST /post HTTP/1.1" 403 225 3.043 "http://localhost:4000/" "Mozilla/5.0 (iPhone; CPU iPhone OS 13_2_3 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/13.0.3 Mobile/15E148 Safari/604.1" - - - "http://apiv2.ninjacart.in"`

### Steps to Reproduce
1. Run the apisix with docker image
2. Configure a route with post method, i used httporg post api like below
`yaml
routes:
-
uri: /post
upstream:
nodes:
"httpbin.org:80": 1
type: roundrobin
plugins:
forward-auth:
_meta:
disable: false
request_headers:
- Authorization
ssl_verify: false
request_method: GET
uri: >-
https://<AUTHSERVER_URL>`
4. Use the curl like below
`shell
curl --location 'https://localhost:9080/post' \
--header 'Accept: application/json, text/plain, */*' \
--header 'Authorization: Bearer <TOKEN>' \
--header 'Content-Type: application/json' \
--data '{
"payload" {
"foo": "bar"
}
}'
`
5. You should see a 403 error, because authserver doesnt accept the content-type header to GET request. This depends on the auth server you use, in my case Im using springboot 3.1.4 on Java 17
