流程：登录注册功能,通过uni.getUserProfile获取wxcode,通过wxcode传给后端获取openid,sessionkey,unionid。
通过<u-button type="success" open-type="getPhoneNumber" @getphonenumber="decryptPhoneNumber">一键登录</u-button>,
传到后端这些参数:
'session_key': $this.openidData.sessionKey,
'encryptedData': e.detail.encryptedData,
'iv': e.detail.iv
获取手机号,
再将手机号，unionid，openid传到后端进行登录
