Nginx Rtmp支持websocket访问吗

是的，Nginx Rtmp模块是支持WebSocket访问的。可以使用WebSocket作为RTMP服务器的另一种方式，它可以在浏览器中使用JavaScript等语言进行RTMP流的播放和发布。要启用WebSocket支持，需要在Nginx配置文件中添加以下内容：

rtmp {
    ...
    server {
        listen 1935;
        listen 8080;
        chunk_size 4000;
        ...
        location /live {
            allow publish all;
            allow play all;
            # WebSocket support
            # Requires nginx >= 1.4
            # WebSocket support requires nginx RTMP module (ngx_rtmp_module)
            # and nginx HTTP module (ngx_http_module)
            # May require additional modules to support various browsers
            # such as "nginx-module-sts" for Safari
            # https://github.com/arut/nginx-rtmp-module/wiki/Directives#sts
            # Also see the "ssl" directive to use WSS instead of WS
            proxy_pass http://localhost:8081;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection "upgrade";
        }
        ...
    }
}

在上面的配置示例中，我们将RTMP服务器的WebSocket支持配置在“/live”位置，并将其代理到localhost:8081。注意，启用WebSocket支持需要使用ngx_rtmp_module和ngx_http_module模块，以及可能需要其他模块来支持不同的浏览器。
