/*
* 判断阶段：
*
* (判断是否需拦截（CallBack回来，结尾带上标签#WxCallBack）----该方式不成立，如果转发分享这个链接到朋友圈之类的就不行了)
* 获取用户名，获取Session中存储的CurrOpenID及UserID
* 判断当前用户是否已进行微信认证,只有微信认证过的用户才允许使用网页授权
* 判断Session，是否已有CurrOpenID，判断新的用户名是否等于旧的用户名：如果已有CurrOpenID但是新的用户名跟旧的用户名不一致，则重新授权获取当前的OpenID
* (这样判断解决问题：比如有两张页面，第一张页面是张三发的报名，第二张页面是李四发的报名，而openID在张三和李四这边都不一样)
*
* 判断是否符合拦截条件
*
* 最后不管符合不符合拦截条件，如果UserID存在有并是数据库用户，都存储用户ID
*
* --------------------------------------
*
* 开始授权处理阶段：
*
* 获取配置的高级接口参数
* 构造CallBackUrl
* 构造返回参数：目前传递Path(当前路径)，UserID
* 构造授权链接
* 访问授权链接
*
* ---------------------------------------
* CallBack处理阶段:
* 接收参数 code，Path，UserId,CurrOpenId
* 构造授权API
* 获取OpenID
* 构造目标链接：Path + UserID
* 存储当前微信OpenID到Session
* 访问最终目标链接(已取到CurrOpenID)
*
* 2013.12.06修改逻辑：自动判断授权模式
* callback回来后，根据openId查询获取是不是会员，如果不是会员，则重新返回授权用userInfo方式
* 注册会员那边自动添加拉取到的微信会员信息
*
*
* 2013.12.19
* 更改后的方法升级：1.直接授权后登录；2.不是会员的则会自动注册会员；3.openId直接是登录凭据；
*
* 判断是否授权依据是登录标识为登出，登出状态才进行授权登录，openId为空也进行登录
*
* 获取用户当前的openid-判断用户是否已注册-如果未注册则自动生成一个随机userId进行注册
*
* 登录标识标为已登录，并获取openId及其他信息

/*
* 判断阶段：
*
* (判断是否需拦截（CallBack回来，结尾带上标签#WxCallBack）----该方式不成立，如果转发分享这个链接到朋友圈之类的就不行了)
* 获取用户名，获取Session中存储的CurrOpenID及UserID
* 判断当前用户是否已进行微信认证,只有微信认证过的用户才允许使用网页授权
* 判断Session，是否已有CurrOpenID，判断新的用户名是否等于旧的用户名：如果已有CurrOpenID但是新的用户名跟旧的用户名不一致，则重新授权获取当前的OpenID
* (这样判断解决问题：比如有两张页面，第一张页面是张三发的报名，第二张页面是李四发的报名，而openID在张三和李四这边都不一样)
*
* 判断是否符合拦截条件
*
* 最后不管符合不符合拦截条件，如果UserID存在有并是数据库用户，都存储用户ID
*
* --------------------------------------
*
* 开始授权处理阶段：
*
* 获取配置的高级接口参数
* 构造CallBackUrl
* 构造返回参数：目前传递Path(当前路径)，UserID
* 构造授权链接
* 访问授权链接
*
* ---------------------------------------
* CallBack处理阶段:
* 接收参数 code，Path，UserId,CurrOpenId
* 构造授权API
* 获取OpenID
* 构造目标链接：Path + UserID
* 存储当前微信OpenID到Session
* 访问最终目标链接(已取到CurrOpenID)
*
* 2013.12.06修改逻辑：自动判断授权模式
* callback回来后，根据openId查询获取是不是会员，如果不是会员，则重新返回授权用userInfo方式
* 注册会员那边自动添加拉取到的微信会员信息
*
