微信支付点金计划配置商家小票实现支付完成跳转页面
以下仅适用于微信支付的服务商模式。
在之前的微信支付中，公众号支付和H5网页支付在支付成功后点击完成可直接跳转指定页面。
当前微信已修改，如果没有开通点金计划的服务商，支付后就会直接关闭商家页面；开通点金计划的服务商会跳转官方小票页面，但点击关闭小票页面也是直接关闭商家页面。
只有开通点金计划且设置自定义小票页面才能跳转指定的页面。
开通点金计划
点金计划《产品介绍》
点金计划具体产品开通及操作流程，请参考《点金计划产品文档》
对于点金计划的开通直接参考上述文档即可
自定义商家小票
商家小票的配置参考上述文档，下面介绍小票代码写法
商家小票html代码
将该html页面地址配置到商户“商家小票链接”中，支付成功后会自动跳转到该链接，并携带参数 sub_mch_id、out_trade_no、check_code

获取订单信息接口说明
在接口中要进行订单校验，校验方法参考 《点金计划产品文档》
校验成功返回正常订单信息，失败返回异常信息。
