javascript - Pusher 身份验证套接字 ID 未定义

Question

我正在尝试创建一个私有(private) channel 以允许用户将数据发送到我的node.js 服务器。请求失败，返回 Pusher:subscription_error，错误代码为 500。

我的node.js(服务器端)日志无法将传入请求中的socket_id拉到“/pusher/auth”

app.post( '/pusher/auth', function( req, res ) {
  var socketId = req.body.socket_id;//<--DEBUG: TypeError: Cannot read property 'socket_id' of undefined

  var channel = req.body.channel_name;
  var presenceData = {
    user_id: 'unique_user_id',
    user_info: {
      name: 'Mr Pusher',
      twitter_id: '@pusher'
    }
  };
  var auth = pusher.auth( socketId, channel, presenceData );
  res.send( auth );
} );

这是发送请求的客户端:

   // Create new Pusher instance and connect
        var key = "<%= appKey %>"  
        var id = "<%= appKey %>"  
        var secret = "<%= appSecret %>"  
        var pusher = new Pusher( "<%= appKey %>" );

// Subscribe to the channel that the event will be published on
var channel = pusher.subscribe( 'private-channel' );
    channel.bind('pusher:subscription_succeeded',function(){
            alert("subscription succeeded")
            var triggered = channel.trigger("client-event",{})
            alert("triggered "+triggered)
    })
    channel.bind('pusher:subscription_error',function(status){
            alert("subscription error "+status)//<-- This error gets returned
    })
// Bind to the event on the channel and handle the event when triggered
channel.bind( 'client-event', function( data ) {
  // For now, alert the message.
  alert( data.message );
} );

这应该由推送 API 自动处理，还是需要显式发送？如何将socket_id发送到服务器？我怎样才能访问客户端上的socket_id变量？

听起来您需要设置 bodyParser 来解析请求正文并使 request.body 可用。
