微信电子发票--“自建平台模式”--小程序开票-即速应用

注：小程序开发票在官方文档（https://mp.weixin.qq.com/wiki?t=resource/res_main&id=21518166863ccFdP）的第四节

项目说明

1.我有一个小程序，是交通行业的。用户买完票之后，可以在电子票页面申请开电子发票；

2. 小程序开发票用的是公众号的access_token，发送到用户卡包也是通过公众号发的，小程序要做的是申请电子发票和完成授权。
3. 虽然买完票就能申请发票，但是为了减少后续的冲红操作，在用户乘车之后才会去申请第三方平台开发票；
4. 代码用的是PHP。

项目大概逻辑

1. 商户获取获取access_token。（方法：getAccessToken()）
2. 提前获取开票平台标识s_pappid（方法：getInvoiceUrl()）
3. 设置商户联系方式（方法：setContact()）
4. 商户获取授权页（方法：getTicket()）；
5. 商户获取授权页url（方法：getAuthUrl()）；
6. 根据第5步的结果，在小程序开票按钮的点击事件上部署跳转到小程序授权页的逻辑；
7. 获取用户填写的抬头信息有两种办法：1）主动查询授权状态（方法：getAuthData()）、2）根据授权回调获取授权状态（方法：getAuthDataWxAccount()）；
8. 创建发票卡券模板（方法：getInvoiceCardId()）；
9. 在自建发票平台开具电子发票（意思是，自己去开发票，比如通过第三方开票平台，然后把开票返回的发票号码、发票代码、发票pdf文件等保存下来；最后再用这些信息调用微信的PDF上传接口和下发到用户卡包的接口）；
10. 上传发票PDF文件（方法：setPDF()）；
11. 将电子发票添加到用户微信卡包（方法：sendInvoice()）。

注：具体的使用方法请看“调用示例”

代码与说明

说明：域名空间下面引用的类，基本上都是数据库操作，大家可以不用看，主要是所取到的要用的字段含义。

AppIdModel用的表是zc2_ticket_appid，请求微信接口用到的字段基本都在这张表了：

调用示例

1.获取授权链接

$invoiceClass = new Invoice();$appId = PhalApiDI()->config->get('app.kgkx.wxAppId');//用于获取对应（zc2_ticket_appid）的配置信息$uid = $this->uid;//车票所属的用户openid$order_no = $this->orderNo;//车票所属的订单号$ticket_no = $this->ticketNo;//车票号//getWxAuthUrl方法已经包含了“大概逻辑”里的前5步，最后只要将授权链接在小程序打开即可$invoiceClass ->getWxAuthUrl($appId,$uid,$order_no,$ticket_no);

返回结果

{    "ret": 200,    "data": {        "errcode": 0,        "errmsg": "ok",        "auth_url": "pages/auth/auth?s_pappid=d3g1Y2Q4NTI3NWI4NDdlM2I2X7xcO5NPKJ9cUhYRLlygl8Dc2ZUl9PjYwiOwmLytYQwA&appid=wx5cd85275b847e3b6&num=1&o1=201904191345503490_0028657333&m1=15&t1=1557816628&source=wxa&type=1&signature=75dcbd921494457089d6c59534f9769624802b27",        "appid": "wx9db2c16d0633c2e7"    },    "msg": ""}

2. 小程序打开授权链接代码

//发票授权  invoiceAuth: function () {    wx.navigateToMiniProgram({      appId: 'wx9db2c16d0633c2e7',      path: 'pages/auth/auth?s_pappid=d3g1Y2Q4NTI3NWI4NDdlM2I2X7xcO5NPKJ9cUhYRLlygl8Dc2ZUl9PjYwiOwmLytYQwA&appid=wx5cd85275b847e3b6&num=1&o1=201904191345503490_0028657333&m1=15&t1=1557816628&
