wechat-login

A koa middleware for wechat login open API

#Install npm install --save wechat-login

#Usage

var wechat = require('wechat-login');

router.get('/login', wechat({
  appID: '{{appID}}',
  appSecret: '{{appSecret}}',
  domain: '{{api.example.com}}'
}, CallBack);

###Notice You should use same config both in koa's router path and wechat callback domain. The configures of appID and appSecret are required while the configure of domain, which is your callback domain of WeChat public platform, is optional. The default value of domain is you host name. The CallBack function has two ways to accept wechat user info and token.

##Use function parameters

function*(token, userInfo) {
  console.log('finished login.');
  this.body = {
    userInfo: userInfo,
    token: token
  }
})

##Use Koa Context

function* (){
  this.body = {
    userInfo: this._wechat.userInfo,
    token: this._wechat.token
  }
}

The userInfo and token is json object, same as wechat official documents.
