验证微信请求 with 'weixin/middleware'
解析推送消息 with 'weixin/model'
生成回复消息 with 'weixin/model'

Installation

$ gem install rack-weixin

Usage

A sinatra demo

# -*- encoding : utf-8 -*-
require 'sinatra'
require 'rack-weixin'

use Weixin::Middleware, 'your api token', '/your_app_root' 

configure do
    set :wx_id, 'your_weixin_account'
end

helpers do
  def msg_router(msg)
    case msg.MsgType
    when 'text'
      # text message handler
    when 'image'
      # image message handler
    when 'location'
      # location message handler
    when 'link'
      # link message handler
    when 'event'
      # event messge handler
    when 'voice'
      # voice message handler
    when 'video'
      # video message handler
    else
      Weixin.text_msg(msg.ToUserName, msg.FromUserName, '未知消息类型')
    end
  end
end

get '/your_app_root' do
    params[:echostr]
end

post '/your_app_root' do
    content_type :xml, 'charset' => 'utf-8'

    message = request.env[Weixin::Middleware::WEIXIN_MSG]
    logger.info "原始数据: #{request.env[Weixin::Middleware::WEIXIN_MSG_RAW]}"
    
    # handle the message according to your business logic
    msg_router(message) unless message.nil?
end

Padrino下使用

在Gemfile里加入:

gem 'rack-weixin'

在config/apps.rb关闭以下两个：

set :protection, false
set :protect_from_csrf, false

在app.rb里加入：

use Weixin::Middleware, 'your api token', '/your_app_root' 

configure do
	  set :wx_id, 'your_weixin_account'
end

Rack和Rails ActionController配合下使用

class WeixinController < ActionController::Base

  def index
    params[:echostr]
  end

  def create

    xml_message = request.env[Weixin::Middleware::WEIXIN_MSG]

    raw_message = request.env[Weixin::Middleware::WEIXIN_MSG_RAW]

    Rails.logger.debug "raw_message = " do
      raw_message
    end

    if xml_message.present?
      response_xml = msg_router(xml_message)

      Rails.logger.info "Weixin response_xml = " do
        response_xml
      end

    end

    if response_xml.present?
      render xml: response_xml
    else
      render :nothing => true, :status => 200, :content_type => 'text/html'
    end

  end

  def msg_router(msg)
    case msg.MsgType
      when 'text'
        text_parse(msg)
      when 'image'
        image_parse(msg)
      when 'location'
        location_parse(msg)
      when 'link'
        link_parse(msg)
      when 'event'
        event_parse(msg)
      when 'voice'
        voice_parse(msg)
      when 'video'
        video_parse(msg)
      else
    end

  end

end

Rails before_filter验证消息，用于接入多个微信公众号

class WeixinController < ActionController::Base

  before_filter :check_signature

  def index
    render :text => params[:echostr]
  end

  def create

    raw_msg = env[Weixin::Middleware::POST_BODY].read

    begin

       xml_message = Weixin::Message.factory(raw_msg)

    rescue Exception => e
      message = "weixin post message error!"
      Rails.logger.error "#{message} params = " do
        params
      end
    end
    
    Rails.logger.debug "raw_message = " do
      raw_message
    end

    if xml_message.present?
      response_xml = msg_router(xml_message)

      Rails.logger.info "Weixin response_xml = " do
        response_xml
      end

    end

    if response_xml.present?
      render xml: response_xml
    else
      render :nothing => true, :status => 200, :content_type => 'text/html'
    end


  end

  private

  def msg_router(msg)
    case msg.MsgType
      when 'text'
        text_parse(msg)
      when 'image'
        image_parse(msg)
      when 'location'
        location_parse(msg)
      when 'link'
        link_parse(msg)
      when 'event'
        event_parse(msg)
      when 'voice'
        voice_parse(msg)
      when 'video'
        video_parse(msg)
      else
    end

  end

  def check_signature


    fullpath = "#{request.protocol + request.host_with_port + request.path}"

    Rails.logger.debug "fullpath = " do
      fullpath
    end

    # 根据fullpath查询不同的token
    # token = query_token_by_fullpath(fullpath)

    Rails.logger.debug "token = " do
      token
    end

    if token.present? && Weixin::Middleware.request_is_valid?(token, params)


    else

      Rails.logger.error "token is null or request_is_valid! params = " do
        params
      end

      render :status => 401

    end

  end


end
