example
simple
var weixin = require('.')
var co = require('co')
co(function *(){
var token = yield weixin.getToken('wx0e9ccf43c71f8bab', 'd97eb68dc872c9c940d96a1e55c2d7a3')
console.log('token:', token)
var ticket = yield weixin.getTicket(token.access_token)
console.log('ticket:', ticket)
var sign = yield weixin.sign(ticket.ticket, 'http://weixin.com')
console.log('sign:', sign)
})sign a url, just need appid + secret
function *() {
var query = this.query
var token = yield weixin.getToken(query.appid, query.secret, query.expires_in, query.update)
if(token.errcode) return this.body = token
var ticket = yield weixin.getTicket(token.access_token)
if(ticket.errcode !== 0) return this.body = ticket
var result = weixin.sign(ticket, query.url)
result.appId = query.appid
this.body = result
