使用meteor sockjs连接向客户端发送任意消息

Question

我想向特定的DDP客户端发送任意消息。

例如，打电话＆＃34;写＆＃34;来自服务器：

Meteor.server.sessions[ session_id ].socket.write( { data_for_user: "something" } )

但我不确定我应该如何抓住＆＃34;这条消息在客户端上。

我知道以下代码不起作用，但我想在这些方面取得一些成就：

DDP.client.onmessage( function( data ) { 
  // i'm guessing i would have to filter my messages
  // since all DDP messages fire here?
  if( data.data_for_user ) {
    // Do i need to tell DDP to don't parse my custom message?
    console.log( "got something for you", data )
  }
} );

Answer 1

您可以像这样在客户端上捕获DDP消息。

var original = Meteor.connection._livedata_data;
Meteor.connection._livedata_data = function (msg) {
  console.log(msg)
  return original.call(this, msg);
}
