与android的socket.io通信

Ben*_*Ben 9 android node.js socket.io cordova

问题摘要

我正在尝试将一个简单的socket.io聊天应用程序捆绑到本机应用程序中,以便在Android 2.2及更高版本上使用phonegap运行.

socket.io Web客户端 - > socket.io服务器工作

我有一个运行socket.io的简单服务器,当它在Web浏览器中运行时,它成功地与socket.io客户端通信.

移动浏览器中的socket.io移动客户端 - > socket.io服务器工作

需要注意的是,因为WebSockets的支持的arent在Android 2.2则默认回XHR轮询,通过Web浏览器在Android 2.2的连接时,从服务器消息样本

   info  - socket.io started
   debug - destroying non-socket.io upgrade

我认为这是因为尝试使用websockets连接到socket.io服务器而不使用socket.io客户端js.我只用node.js服务器测试它,它工作

问题

  1. 有没有办法告诉socket.io关于在Android的Phonegap应用程序中使用WebSocket支持创建的websocket ？
  2. 为什么xhr轮询超时？

您将需要查看您的 HTTP 标头。我的猜测是客户端要么没有发送保持活动状态，要么被服务器忽略。在客户端发送的 XHR 请求中查找“Connection: keep-alive”。还要查看服务器端的响应。另一个指标可能是发送的http版本。1.0将意味着连接将在请求后关闭。
