微信自动回复

在最简单的 rails 工程的基础上，添加了处理微信公众号自动回复的逻辑：

Gemfile:

# 读取 application.yml 配置
gem "figaro", "~> 1.1.1"

# 微信回复处理
gem 'weixin_rails_middleware', '~> 1.3.2'

https://github.com/lanrion/weixin_rails_middleware

config/application.yml

development:
  # 微信自动回复相关配置
  WECHAT_REPLY_APPID: ....
  WECHAT_REPLY_APPSECRET: ....
  WECHAT_TOKEN: ....
  WECHAT_ASE_KEY: ....

config/routes.rb

Rails.application.routes.draw do
  # 微信回复处理
  mount WeixinRailsMiddleware::Engine, at: "/"
end

added config/initializers/weixin_rails_middleware.rb

使用沙箱环境调试：

回复逻辑都写在：
app/decorators/weixin_rails_middle_ware/weixin_controller_decorator.rb

运行方法

bundle install
npm install
rails s -b 0
