主要的函数是start()函数,当中写了注释内容,可以根据自己的需要进行修改
3、客户端JavaScript websocket
这里客户端页面加载后就与服务器端进行连接,如果成功之后,就会执行onopen,如果服务器发送内容,执行onmessage,其中event是服务器发送的对象。查看更多
4、运行步骤
1)下载源代码至本地
2)修改run.bat文件存放路径
3)双击运行脚本
4)打开浏览器,我是放在Apache的www文件夹下面的,输入http://127.0.0.1/websocket/wobsocket.html
5)如果报错
表示Server_socket.php 没有执行,也可能是火狐浏览器的websocket没有打开。
打开火狐浏览器的websocket方法
1)地址栏输入about:config
2)回车,搜索框输入websocket,将与websocket有关的内容全部打开,重启浏览器。
6)执行效果
左边的cmd是执行run.bat的脚本
右边的控制台是客户端执行的有关打印
可以看出,客户端发送的信息被服务端接收,并且服务端发送的内容客户端也可以被接收。
之所以要做这个是有关实现团队前端主机创建成员,从机加入后,推送消息给主机,是哪一个成员加入,以及主机点击开始操作之后,主机和从机同时进入操作页面。
另外,还可能后期还会有操作期间的会话,其实这个已经可以简单实现,不过问题是需要区分团队,每一个团队有一个聊天室。以及发送消息区分每一个用户。可能后期会参考打开,以及打开
