Rails ActionCable没有收到数据

Question

我有两台服务器

1. API服务器（Rails＆amp; ActionCable）
2. 客户服务器（Rails 5.1＆amp; Vue js＆amp; actioncable from Yarn）
API服务器上的

：

app / channels / operation_channel.rb
中的

class OperationChannel < ApplicationCable::Channel
    def subscribed
        stream_from 'operations'
    end

    def unsubscribed
        # Any cleanup needed when channel is unsubscribed
    end
end

在config / environments / production.rb
中

config.action_cable.disable_request_forgery_protection = true

在config / routes.rb

中

mount ActionCable.server => '/cable'

app / models / operation.rb

class Operation < ApplicationRecord
    [...]

    after_update :broadcast

    def broadcast
        ActionCable.server.broadcast "operations", operation: self
    end

    [...]
end

客户服务器上的

：

在main.js中

import ActionCable from 'actioncable'

var cable = ActionCable.createConsumer('wss://[APIs server URL]/cable');

var operations = cable.subscriptions.create('OperationChannel', {
    connected: function() {
        console.log("connected");
    },
    disconnected: function() {
        console.log("disconnected");
    },
    received: function(data) {
        console.log('received');
        console.log(data);
    }
});

我只能在web-socket服务器停止时调用断开连接的回调，并且我可以在日志中看到web-socket信息：

Started GET "/cable/" [WebSocket] ...
Successfully upgraded to WebSocket (REQUEST_METHOD: GET, HTTP_CONNECTION: upgrade, HTTP_UPGRADE: websocket)
.
.
.
[ActionCable] Broadcasting to operations: {:operation=>#<Operation id: 1,...

我已经做了很多研究，但仍然可以接收来自广播的任何数据，并且连接的回调也永远不会被调用，请帮忙。感谢
