微信现金红包接口实现红包发放的示例代码分享

微信现金红包接口实现红包发放:

一:流程:【

流程:微信用户访问红包活动页面--》后端判断是否是微信访问的

【否:提示用微信打开连接,是:提示用户是否授权允许,获取其的用户信息【openID等信息】】--》

进入红包活动页面---》用户点击领取红包【判断是否领取过红包】是:【提示已领取过红包】否

--》后端程序调用接口发放红包

--》微信用户在微信中收到红包

--》打开红包

--》红包金额会添加到钱包零钱里

--》完成红包发放。

二:要实现微信现金红包接口实现红包发放,首先要符合以下条件:

1.用于发放红包的微信公众号要是服务类型

2.登录微信公众平台官网后,在公众平台后台管理页面 - 开发者中心页,

点击“修改配置”按钮,填写服务器地址(URL)、Token和EncodingAESKey,

其中URL是开发者用来接收微信消息和事件的接口URL。Token可由开发者可以任意填写,

用作生成签名(该Token会和接口URL中包含的Token进行比对,从而验证安全性)。

EncodingAESKey由开发者手动填写或随机生成,将用作消息体加解密密钥。

3.获取access_token:公众号可以使用AppID和AppSecret调用本接口来获取access_token。

【AppID和AppSecret可在微信公众平台官网-开发者中心页中获得(需要已经成为开发者,且帐号没有异常状态)。】

4.微信公众号要开通 “网页授权接口” 用户获取用户基本信息【特别是openID ,发红包时用到】

5.微信公众号的 “微信支付“ 中的 ”商户号” 要开通微信支付【发红包的金额是该支付账户扣款】,开通“现金红包”接口【调用该接口发放红包】。

6. 登陆 ”商户号”【微信公众号分配的商户号。第5 中有说明】 在 “API安全” 中 下载PHP版的 证书 【.pem格式】

以上如描述不清楚,请查看 微信开发者文档 里面有详细的秒杀。
