* 通过code换取网页授权access_token和openid的返回数据，正确时返回的JSON数据包如下：
* {
* "access_token":"ACCESS_TOKEN",
* "expires_in":7200,
* "refresh_token":"REFRESH_TOKEN",
* "openid":"OPENID",
* "scope":"SCOPE",
* "unionid": "o6_bmasdasdsad6_2sgVt7hMZOPfL"
* }
* 其中access_token可用于获取共享收货地址
* openid是微信支付jsapi支付接口统一下单时必须的参数
* 更详细的说明请参考网页授权获取用户基本信息：http://mp.weixin.qq.com/wiki/17/c0f37d5704f0b64713d5d2c37b468d75.html
* @失败时抛异常WxPayException
