lua-resty-websocket安装和测试

作者:杨鑫奇

关注Openresty很久了,期待支持websocket终于出来了,看到Aapo Talvensaari同学写的文章https://medium.com/p/1778601c9e05,兴奋下也来测试下,之前用websocket做即时通讯,还是基于socket.io的例子,现在用nginx来做...初尝试下,竟然报错了,章哥的解答在这里:
https://github.com/agentzh/lua-resty-websocket/issues/2 ,现在配置成功了,将自己的配置过程写下来,希望对大家有所帮助.

 

主要原因是:

websocket依赖于 lua-nginx-module,得用最新版本的,下面是章哥给的配置.
我用最新的1.4.2.7编译并测试成功的了.

 

到自己的目录下:
下载最新版本的 openresty 和 lua-nginx-module 然后安装:
wget http://openresty.org/download/ngx_openresty-1.4.2.7.tar.gz
tar zxvf ngx_openresty-1.4.2.7.tar.gz
git clone https://github.com/chaoslawful/lua-nginx-module.git
cd lua-nginx-module
git checkout -b websocket origin/websocket
cd ../ngx_openresty-1.4.2.7/bundle
rm -Rf ngx_lua-0.8.9
ln -s ../../lua-nginx-module ngx_lua-0.8.9
cd ..
./configure -with-luajit -prefix=/usr/local
gmake && gmake install

安装完成后
cd ../
git clone https://github.com/agentzh/lua-resty-websocket.git
拷贝websocket到lualib目录下
cp -r lua-resty-websocket/lib/resty/websocket /usr/local/lualib/resty/

配置自己的nginx conf的内容
在nginx.conf中添加lualib的路径
lua_package_path "/usr/local/lualib/resty/websocket/?.lua;;";

我这里是独立开的yagamiko.conf,添加websocket:
在server段内,修改添加以下内容:

listen 80 default so_keepalive=2s:2s:8;

这个是Aapo Talvensaari同学写的测试代码: 

location /1.0/websocket {

  lua_socket_log_errors off;

  lua_check_client_abort on;

  content_by_lua '

    local server = require "resty.websocket.server"

    local wb, err = server:new{

    timeout = 5000,  -- in milliseconds

    max_payload_len = 65535,

    }

    if not wb then

      ngx.log(ngx.ERR, "failed to new websocket: ", err)

      return ngx.exit(444)

    end

    while true do

      local data, typ, err = wb:recv_frame()

      if wb.fatal then

        ngx.log(ngx.ERR, "failed to receive frame: ", err)

        return ngx.exit(444)

      end

      if not data then

        local bytes, err = wb:send_ping()

        if not bytes then

          ngx.log(ngx.ERR, "failed to send ping: ", err)

          return ngx.exit(444)

        end

      elseif typ == "close" then break

      elseif typ == "ping" then

        local bytes, err = wb:send_pong()

        if not bytes then

          ngx.log(ngx.ERR, "failed to send pong: ", err)

          return ngx.exit(444)

        end

      elseif typ == "pong" then

        ngx.log(ngx.INFO, "client ponged")

      elseif typ == "text" then

        local bytes, err = wb:send_text(data)

        if not bytes then

          ngx.log(ngx.ERR, "failed to send text: ", err)

          return ngx.exit(444)

        end

      end

    end

    wb:send_close()

  ';

}

 

 

然后重新启动nginx就可以了...

使用 这个哥们提到的测试html,就可以了 https://medium.com/p/1778601c9e05

<html>
<head>
<script>
var ws = null;
function connect() {
  if (ws !== null) return log('already connected');
  ws = new WebSocket('ws://ko.local.freeflare.com/1.0/websocket');
  ws.onopen = function () {
    log('connected');
  };
  ws.onerror = function (error) {
    log(error);
  };
  ws.onmessage = function (e) {
    log('recv: ' + e.data);
  };
  ws.onclose = function () {
    log('disconnected');
    ws = null;
  };
  return false;
}
function disconnect() {
  if (ws === null) return log('already disconnected');
  ws.close();
  return false;
}
function send() {
  if (ws === null) return log('please connect first');
  var text = document.getElementById('text').value;
  document.getElementById('text').value = "";
  log('send: ' + text);
  ws.send(text);
  return false;
}
function log(text) {
  var li = document.createElement('li');
  li.appendChild(document.createTextNode(text));
  document.getElementById('log').appendChild(li);
  return false;
}
</script>
</head>
<body>
  <form onsubmit="return send();">
    <button type="button" onclick="return connect();">
      Connect
    </button>
    <button type="button" onclick="return disconnect();">
      Disconnect
    </button>
    <input id="text" type="text">
    <button type="submit">Send</button>
  </form>
  <ol id="log"></ol>
</body>
</html>

  

 

测试....这里注意在同一个域名下就好了....

测试成功了....

 

 

接下来尝试将之前写的即时聊天的逻辑移植过来.....

章哥太给力了,Openresty 很赞啊....
