nginx使用lua通过request_body按条件开放访问权限

需求：当我们的请求在我们条件内的主机上时只允许balance.query和asset.list请求，其余主机不受限制

1、部署nginx以及添加lua模块

upstream algoapp {
   server 192.168.1.91:8080;
}
server {
        listen      80;
        server_name  abc.test;
        location / {
                if ($request_method = POST ) {
                    set $upstream '';
                    access_by_lua '
                    ngx.req.read_body()
                    local data = ngx.req.get_body_data()
                    local match = ngx.re.match(ngx.var.request_body, "balance.query|asset.list")
                    local addr = ngx.re.match(ngx.var.remote_addr, "172.16.3.11|172.16.3.20|192.168.1.27|192.168.1.60|172.16.9.2|192.168.1.159")
                    if addr then
                        if match then
                            ngx.var.upstream = "algoapp"
                        else
                            return 403
                        end
                    else
                        ngx.var.upstream = "algoapp"
                    end ' ;
                proxy_pass http://$upstream;
                }
               #proxy_pass http://algoapp;
                proxy_set_header Host $http_host;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For  $proxy_add_x_forwarded_for;
        }
}

测试：
1、在条件内的不同主机上执行balance.query请求
在主机192.168.1.159

[root@openvpn data]# ifconfig |grep "192.168.1.159"
        inet 192.168.1.159  netmask 255.255.255.0  broadcast 192.168.1.255
[root@openvpn data]# curl -H "Content-Type: application/json" -X POST -d '{"method":"balance.query","id":1,"jsonrpc":"2.0","params":[634272,"AITD"]}' http://abc.test
{
    "error": null,
    "result": [
        {
            "asset": "AITD",
            "available": "0",
            "freeze": "0"
        }
    ],
    "id": 1
}

在非主机192.168.1.36

[root@build-serice jenkins]# ifconfig |grep "192.168.1.36"
        inet 192.168.1.36  netmask 255.255.255.0  broadcast 192.168.1.255
[root@build-serice jenkins]#  curl -H "Content-Type: application/json" -X POST -d '{"method":"balance.query","id":1,"jsonrpc":"2.0","params":[634272,"AITD"]}' http://abc.test
{
    "error": null,
    "result": [
        {
            "asset": "AITD",
            "available": "0",
            "freeze": "0"
        }
    ],
    "id": 1
}

显示都可以操作，此时符合需求
2、测试asset.list请求
在条件主机192.168.1.159

[root@openvpn data]# curl -X POST --data '{"jsonrpc":"2.0","method":"asset.list","params":[], "id":1}' -H 'Content-Type: application/json'  http://match-reward.sgpexchange.test
{
    "error": null,
    "result": [
        {
            "name": "1INCH",
            "prec": 8
        },
        {
            "name": "ABC",
            "prec": 8
        },
        {
