Question

我希望流式传输从证券交易所（通过websocket）收到的数据并将数据广播到客户端。我认为动作电缆是最好的方法，但到目前为止还没有成功。

＆＃34; DataProvider＆＃34;在Ruby上构建了一个SDK，用于在我的服务器和股票交易服务器之间建立连接。我已经能够成功连接，但没有看到数据流。

有什么建议吗？

频道：

class StockPriceChannel < ApplicationCable::Channel
  def subscribed
    stream_from "portfolio_#{params[:portfolio_id]}"

  end

  def unsubscribed
    # Any cleanup needed when channel is unsubscribed
    EventMachine.stop()
  end

  def receive(data)
    tickers = data["message"]

    tickers = tickers.split(",")

    puts tickers


    options = {
       username: ENV["DataProvider_USERNAME"],
       password: ENV["DataProvider_PASSWORD"],
      channels: tickers
     }

    EventMachine.run do

     client = DataProvider::Realtime::Client.new(options)
      client.on_quote do |quote|
        StockPriceChannel.server.broadcast_to("portfolio_#
 {params[:portfolio_id]}",quote)
      end
      client.connect()

      EventMachine.add_timer(1) do
        puts "joining tickers"
        client.join(tickers)
      end

  #     EventMachine.add_timer(10) do
  #       client.disconnect()
  #       EventMachine.stop()
  #     end

    end
  end
end

ReactJS（在componentDidMount（）中）

App.portfolioChannel = App.cable.subscriptions.create(
  {
    channel:"StockPriceChannel",
    portfolio_id:this.props.match.params.port_id
  },
  {
    connected: () => console.log("StockPriceChannel connected"),
    disconnected: () => console.log("StockPriceChannel disconnected"),
    received: data => {
      debugger;
      console.log(data)
    }
  }
)
App.portfolioChannel.send({
  message:"AAPL,MSFT"
})

嗯......我希望这（至少）帮助其他人。

我意识到我的问题是

StockPriceChannel.server.broadcast_to("portfolio_#
    {params[:portfolio_id]}",quote)

应该是

ActionCable.server.broadcast_to("portfolio_#
    {params[:portfolio_id]}",quote)

Action Cable（Rails 5）从证券交易所提取数据
