get real-ip issue

[ray1888]

i am using kong developing with a proxy-wasm base gosdk for some bussine logic, but i can't the the real ip with X-REAL-IP in header

using default config of kong container config like this

_format_version: "1.1"
_transform: true

services:
- name: demo
  url: http://my-service
  routes:
  - name: my-route
    paths:
    - /
    strip_path: false
    filter_chains:
    - filters:
      - name: gitee-acl
        config: 
          cluster_name: 192.168.3.200:10000
          acl_service_host: 127.0.0.1
          acl_service_port: "10000"


upstreams:
  - name: my-service
    targets:
      - target: 192.168.3.200:10001
        weight: 100

my getting header code is below

hs, err := proxywasm.GetHttpRequestHeaders()
if err != nil {
proxywasm.LogErrorf("failed to get request headers: %v", err)
return types.ActionContinue
}

var clientIp string

var tenantId string
for _, h := range hs {
proxywasm.LogDebugf("header is %s , value %s", h[0], h[1])
if h[0] != verify.CookieHeader && h[0] != verify.REALIPHeader {
	continue
}
key := strings.TrimSpace(h[0])
if key == verify.CookieHeader {
	proxywasm.LogDebugf("get cookies")
	_, tenantId, _ = verify.GetTenant(h[1])
} else if key == verify.REALIPHeader {
	proxywasm.LogDebugf("get real ip")
	clientIp = h[1]
}
}

if len(tenantId) == 0 {
proxywasm.LogInfof("Tenant id is 0")
return types.ActionContinue
}

var body []byte

if len(clientIp) == 0 {
proxywasm.LogInfof("clientIP is empty")
return types.ActionContinue
}

but the result is no include x-real-ip sector , logs are below

And i think base on the describe beolwo, realip module will work before my wasm filtter
