[bug] on_publish回调参数的问题

[cokemine]

Expected behavior / 期望行为

on_publish 可以返回自定义参数

Actual behavior / 实际行为

on_publish只能返回默认的几个参数

{
    "app": String,
    "swfurl": String,
    "tcurl": String,
    "pageurl": String,
    "addr": String,
    "clientid": String,
    "call": String,
    "name":String
}

OS and Nginx version / 操作系统和 Nginx 版本号

Debian GNU/Linux 10
nginx version: nginx/1.18.0

Configuration file / 配置文件

rtmp {
    out_queue 4096;
    out_cork 8;
    max_streams 128;
    timeout 15s;
    drop_idle_publisher 15s;
    server {
        listen 1935;
        application hls {
            live on;
            publish_notify on;
            on_publish http://127.0.0.1:35602/auth;
            hls on;
            hls_path /data/wwwroot/hls;
        }
    }
}

Steps to reproduce the behavior / 复现问题步骤

在server层使用on_connect url的话，是可以返回自定义参数的，比如向rtmp://url:1935/hls?pass=123，后端验证可以接收到POST来的

{
	"pass":123
}

但是在application使用on_publish无法接收到自定义的参数
