Omniauth Strategy for https://open.weixin.qq.com/

微信开放平台的Omniauth Strategy

Installation

gem "omniauth-wechat-oauth2", git: '[email protected]:yangsr/omniauth-wechat-oauth2.git'

Usage

Here's an example for adding the middleware to a Rails app in config/initializers/omniauth.rb:

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :wechat, ENV["WECHAT_APP_ID"], ENV["WECHAT_APP_SECRET"]
end

If you want to specify the callback url:

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :wechat, ENV["WECHAT_APP_ID"], ENV["WECHAT_APP_SECRET"],
    :authorize_params => {:redirect_uri => "http://www.example.com/auth/wechat/callback"}
end

You can now access the OmniAuth Wechat OAuth2 URL: /auth/wechat

About Unionid

UnionID机制,官方的解释是:

通过获取用户基本信息接口,开发者可通过OpenID来获取用户基本信息,而如果开发者拥有多个公众号,可使用以下办法通过UnionID机制来在多公众号之间进行用户帐号互通。只要是同一个微信开放平台帐号下的公众号,用户的UnionID是唯一的。换句话说,同一用户,对同一个微信开放平台帐号下的不同应用,UnionID是相同的。

此前的OpenID机制,每个微信号对应每个公众号只有唯一的OpenID,所以不同微信公众号之间是不能共享用户的,现在有了UnionID就可以了。
