Hello.
I'm trying to build nginx source with this module included. Tried nginx 1.6.3 and 1.8.1.
For both versions, configure fails with message:

adding module in /tmp/nginx/websockify-nginx-module-master/
/tmp/nginx/websockify-nginx-module-master//config: line 7: auto/module: No such file or directory

(the double backslash makes no difference)
I'm using Docker image of CentOS 7 with upstream gcc and make.
I can successfully include other modules (ngx_http_auth_pam, nginx-sticky-module-ng) without trouble.

Removing the troublesome line 7 allows successful configuration (ngx 1.8.1), but I'm yet to see if the functionality is there.

return 502 Bad Gateway, remove http2 from nginx listen work.

need this options.

websocket_server_write_frame_header函数建议返回头部长度，这样使用完这个函数可以得到dst应该偏移多少，比如如下

static ngx_inline int
websocket_server_write_frame_header(u_char *dst, u_char opcode,
size_t payload_length)
{
dst[0] = (u_char)((opcode & 0x0F) | 0x80);
if ( payload_length <= 125 ) {
dst[1] = (u_char)(payload_length);

return 2;

}

dst[1] = (u_char) 126;
*(u_short *)&(dst[2]) = htons((u_short)(payload_length));

return 4;
}

使用时：
...
int len = websocket_server_write_frame_header(dst, opcode, payload_length);
dst += len;
...

spice-html5 + xSpice work together to provide a web based spice client similar to how noVNC + xVNC provide a web based VNC client.

The connection does not get passed through using the module. It does however pass through when using the standalone websockify.

The instructions for building are for a static module. Can it be built as a dynamic module

通过 websockfiy 模块连上后端机器，一段时间后会出现连接断开的问题。我们在nginx中进行 TCP 抓包，发现是nginx主动发送FIN包，断开了同前后端的连接，但是断开连接的原因尚不清楚。

以下是抓包的流量图，09:17:03 发送 FIN 包结束两端的连接。
10.0.x.x 是 NGINX 主机，106.52.x.x 是后端 vnc 服务器，172.16.x.x 是前端过来的流量

我们尝试过在upstream块中打开 nginx 的 keep-alive 配置，但是对这个情况没有影响。

单独使用websockify进行转发代理是成功的，使用nginx内置websockify模块，提示协议错误。

127.0.0.1:64738 是聊天服务器

单独使用的代码：
websockify 64737 127.0.0.1:64738 --ssl-target -v --traffic --cert ./self.pem --key .self.pem

nginx配置：
server {
listen 443 ssl;
server_name voice.example.com;
ssl_certificate /etc/letsencrypt/live/voice.example.com/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/voice.example.com/privkey.pem;

    location /chat{
            proxy_pass http://127.0.0.1:64737;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection $connection_upgrade;
    }

}

map $http_upgrade $connection_upgrade {
default upgrade;
'' close;
}

以上是独立使用websockify是运行成功的。

下面是根据本模块的用的配置：

server {
listen 443 ssl;
server_name voice.example.com;
ssl_certificate /etc/letsencrypt/live/voice.example.com/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/voice.example.com/privkey.pem;

    location /chat {
            websockify_pass 127.0.0.1:64738;
    }

}

使用内置服务器提示错误：

2018-03-27 23:30:47.746 1 => <31:(-1)> New connection: 127.0.0.1:29758
2018-03-27 23:30:47.762 1 => <31:(-1)> Connection closed: Error during SSL handshake: error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol [13]

这是啥原因呢？用内置模块就简单方便了很多，但是目前运行不起来。

nginx版本是 1.10.1,下面是编译配置：

--prefix=/usr/local/nginx --user=www --group=www --with-http_stub_status_module --with-http_v2_module --with-http_ssl_module --with-ipv6 --with-http_gzip_static_module --with-http_realip_module --with-http_flv_module --with-openssl=../openssl-1.0.2h --with-pcre=../pcre-8.38 --with-pcre-jit --with-ld-opt='-ljemalloc' --add-module=../websockify-nginx-module/

How to save your log data entered in the terminal?
sniffing??

location /websockify {
websockify_pass 10.58.93.148:5901;
}
websocket：
socket = new WebSocket("ws://10.127.96.195:80/websockify");
浏览器：
http://10.127.96.195/websockify
访问access.log里都是400

Need to expose websocket port 5901 if start with docker?

does it support unix domain sockets?

Are you planning on making a Dockerfile, so one could easily use this with other services whose APIs have to be translated to a websocket API?

Hi,

I'm seeing this in my nginx error log:
2014/06/27 13:22:37 [error] 1651#0: *425 ngx_http_websockify_send_with_encode: encode error! while proxying upgraded connection, client: 10.10.10.10, server: name.server.com, request: "GET /vnc/5002 HTTP/1.1", upstream: "websockify://127.0.0.1:5002", host: "name.server.com"

And this in the firefox console:
New state 'failed', was 'normal'. Msg: Disconnected: illegal hextile subencoding 201

nginx 1.6.0
CentOS 6.5 x86_64
Fedora 20 x86_64

It doesn't happen always, but more frequently in CentOS than Fedora.

Can you help me??

static ngx_int_t ngx_http_websockify_handler(ngx_http_request_t *r)

在这个函数里面。许多返回都不考虑ngx_pcalloc分配内存的释放？

What you wrote is a plug-in for the client (websocket) to access the backstage TCP protocol server through nginx

Are secure (TLS/SSL) WebSockets supported? If so, does the module handle the security and bridge unencrypted TCP traffic to the proxied server?
