以下是实现长轮询的代码。向控制器发送每个请求的长轮询实施
class ApplicationController < ActionController::Base
# Prevent CSRF attacks by raising an exception.
# For APIs, you may want to use :null_session instead.
protect_from_forgery with: :exception
cattr_accessor :acArray
end
ApplicationController.acArray = []
class HelloController < ApplicationController
def initialize
ApplicationController.acArray << self
end
def index
ApplicationController.acArray.each_with_index {|val, index|
if index == 1 # only on second request serve the first request, until then hold the object in memory
val.render :text => ApplicationController.acArray.length
end
}
end
end
的问题是所述第一请求被与所述消息
模板丢失 缺失模板你好/索引,应用程序/索引含{立即失败:区域设置=> [:EN]:格式= > [:html],:handlers => [:erb,:builder,:raw,:ruby,:jbuilder,:coffee]}。搜查:*“/家/ MYHOME的/ tmp /聊天/应用/视图”
如何延迟渲染,而不是让轨道搜索视图文件,而不是返回失败状态
返回相同的错误。没有变化 –
只是好奇,你有没有尝试过在错误发生之前立即打印acArray的长度值? – rboling
我放置** p ApplicationController.acArray.length **之前**下一个**在其中打印1错误之前的块 –
