扫二维码关注服务号同时发现金红包
本文只是记录一下自己最近开发的一个小功能，方便以后查看。
一、需求原文如下：
1.vip微信参数配置
1)是否启用
2)设置每单最大红包金额 (例如5 )
3)设置各类别 红包金额范围
钻石 3-5
黄金 2-3 等等
2.质量保证单
打印二维码 参数传销售门店 以及销售单号
客户扫码
1)自动关注服务号
2)自动匹配客户档案
openid 匹配到档案的增加积分以及总积分 ，
未匹配到档案的 客户填写 姓名,手机号 如果手机号匹配到记录 自动将客户档案关联上
手机号也未匹配到记录 自动建立档案（自动插入所属分销商id,微信openid,姓名,手机号,总积分，剩余积分 必填项添默认值）
3)根据用户结果 自动关联客户消费记录
4)根据积分规则判断消费完客户是否达成升级标准（客户等级只升不降）
5)根据参数配置 自动发送一个红包给客户 同单多次扫描只发送一次红包.
红包规则 1.判断是否启用 没有启用不发送
2.发送红包时 取明细条码里面 红包金额上限最大的 记录 随机生成一个金额的红包发送
例如 客户购买2件货品 钻石 3-5 黄金2-3
那么随机发送一个 3-5元的红包给客户
（暂不考虑销退的情况）
二、需求理解：简单来说就是门店下单时需要在质保单上面打印上我们的服务号二维码（二维码参数带上订单号），扫码时根据openid（客户微信号在我们的服务号唯一的标示）匹配客户表，如果之前已经存在，就根据单号和积分规则计算客户的积分，没发过红包的单就发送一个根据类别配置金额的红包给客户。如果openid没有匹配到就给个链接填写vip信息，之后发送红包和消费记录，同时计算积分。
三、实操
1.服务号申请 2.开通支付功能，下载证书。 3.调用带参数的二维码接口生成二维码。4.响应关注事件（判断用户身份，计算积分，发送红包等）

微信红包功能可以参考：csdn的实例下载。
四、效果
四、开发总结
1.这个功能应该是连接客户比较实用的功能，提高客户的依赖度。
2.开发时调试比较麻烦，我的方法是使用微信服务号的api发送错误日志到我的微信上，另一个方法是自己模拟微信的回调事件（这个方法很好，可以直接在vs中调试）。
