Nginx OpenResty

如何解决Nginx OpenResty

如何使用body_filter_by_lua_block在OpenResty反向代理中记录HTTP响应正文。我正在Nginx.conf文件中尝试此操作。仍然没有在日志中填充resp_body。

log_format  long_format escape=none  '$remote_addr - $server_port - $remote_user [$time_local] - $status - "$request" '
                 '$body_bytes_sent "$http_referer" '
                 '"$http_user_agent" "$http_x_forwarded_for" req_body:"$request_body" resp_body:"$resp_body"';

server{
    listen 9000 ssl;
    access_log  logs/vnfm_eo.log  long_format;
    lua_need_request_body on;
    set $resp_body "";

    body_filter_by_lua_block {
        local resp_body,eof = ngx.arg[1],ngx.arg[2]
    }        

    location / {
        proxy_pass https://10.10.10.4:8000;
    }
}
