Rails 项目同时连接 MySQL 和 Oracle，部署到服务器上后报错 "The connection cannot be reused in the forked process"

kevin_he — Mon, 28 Nov 2016 11:49:58 +0800

项目同时连接了 mysql 和 oracle，本地开发时 mysql 和 oracle 均可正常访问、读取数据，部署到服务器之后，mysql 可以正常访问，但是如果打开一些需要从 oracle DB 读取数据的页面，就会报错：

坐等各位大神帮忙...

使用 Typhoeus 向银联发送 post 请求，代码在本地运行，request.run 速度很快，但是在服务器上运行出错？

kevin_he — Fri, 08 Apr 2016 16:55:34 +0800

request = Typhoeus::Request.new("https://101.231.204.80:5000/gateway/api/backTransReq.do", method: :post, params: post_params[:sign], ssl_verifypeer: false, headers:     {'Content-Type' =>'application/x-www-form-urlencoded'} )
request.run
res = request.response

前天还可以运行，也没有修改这一个方法的代码，但是从昨天开始，就会在 request.run 的时候卡住很长时间，然后发送失败。求指点。

外部 �URL 通过 HTTP，POST 到项目上 notify 这个 action 的参数，怎么获取到？

kevin_he — Thu, 07 Apr 2016 11:15:26 +0800

这是 route 设置

resources :conts do
    collection do
      post 'notify'
    end
  end

这个是 notify 方法

require 'logger'
class ContsController < ApplicationController
  def union_notify
    logger = Logger.new(STDERR)
    notify_params = params.except(*request.path_parameters.keys)
    logger.debug notify_params
  end
end

报错

webhooks 验证公钥失败

kevin_he — Wed, 23 Mar 2016 17:49:00 +0800

下面是我用的验证公钥的方法，但是在服务器上面运行的时候出现错误

def notify
     status = 400
     #判断请求是否有ping++的签名信息
     if request.headers['x-pingplusplus-signature'].blank?
        status = 401
        logger.debug '【报哪家】：======付款回调请求来源错误！！！！！'
        return
     end 
     #获取签名信息
     raw_data = request.body.read
     if request.headers['x-pingplusplus-signature'].is_a?(Array)
        signature = request.headers['x-pingplusplus-signature'][0].to_s
     else
        signature = request.headers['x-pingplusplus-signature'].to_s
     end
     # 获取「Webhooks 验证公钥」
     pub_key_path ="#{Rails.root}/config/rsa_public_key.pem"
     if verify_signature(raw_data, signature, pub_key_path)
            #处理接收的结果
          event = JSON.parse(raw_data) 
          #付款成功
          if event["type"] == 'charge.succeeded'
           # 开发者在此处加入对支付异步通知的处理代码
             order_no = event['data']['object']['order_no']
             order = Order.where(order_no: order_no).first

                 if order.save
                      status = 200
                 else

求大神帮忙解答

cancancan 在引用的时候出现 undefined local variable or method `authorize_resource' for AdminController:Class (NameError)

kevin_he — Mon, 01 Feb 2016 11:46:57 +0800

本人是一个新手，最近尝试使用 cancancan 做权限等级设置，代码写完后，在本地运行通过了，但是部署到服务器上面之后，项目不能正常运行，查看 log 的时候发现提示这个错误，undefined local variable or method `authorize_resource' for AdminController:Class (NameError)，请求大神帮帮忙。

class AdminController < ApplicationController
   authorize_resource
   rescue_from CanCan::AccessDenied do |exception|
     if request.env["HTTP_REFERER"] == nil
       redirect_to admin_activities_path, :alert => exception.message
     else
       redirect_to request.env["HTTP_REFERER"], :alert => exception.message
     end
   end
   def current_ability
      @current_ability = Ability.new(current_user)
   end
end

class Ability
   include CanCan::Ability

   def initialize(user)
      if user.username == "admin"
          can :manage, :all
      else
          can :manage, Activity
      end
   end
end
