Question

我一直试图解决一个我不太懂的错误。怎么会出现无效的真实性令牌错误？

这是终端上的错误：

这是我的消息控制器

 class MessagesController < ApplicationController

  def create
    @message = Message.new(message_params)
    @chatroom = Chatroom.find(params[:chatroom_id])
    @message.chatroom = @chatroom
    @message.sender = current_user

    if @message.save
      respond_to do |format|
        format.html { redirect_to chatroom_path(@chatroom) }
        format.js
      end
    else
      respond_to do |format|
        format.html { render "chatrooms/show" }
        format.js
      end
    end

  end

私有

def message_params params.require（：消息）.permit（：体）端

端

这是我有聊天表格的视图：

<div class="col-xs-4">
  <div class="chat-header"><h4><%= @chatroom.session.title %></h4></div>
  <div class="messages">
    <% @chatroom.messages.each do |message| %>
      <%= render "messages/message", message: message, user_is_messages_author: message.from?(current_user), c_user: current_user %>
    <% end %>
  </div>
  <div id="create-message">
    <%= simple_form_for [ @chatroom, Message.new ], remote: true, html: {autocomplete: "off" } do |f| %>
      <%= f.input :body, label: false %>
    <% end %>
  </div>
</div>

Answer 1

视图might not be creating the authenticity token中的simple_form_for。或者您需要将csrf meta tag放在HTML文档的头部。无论哪种方式，您都试图以旧式方式创建消息，而不是使用websockets。您必须通过actioncable的客户端组件发送消息，如下所述：http://guides.rubyonrails.org/action_cable_overview.html#client-side-components

使用ActionCable进行群聊应用程序会出现错误ActionController :: InvalidAuthenticityToken
