微信支付类（含h5支付、APP二次签名） 最新地址 https://vclove.cn/archives/492.html什么是微信H5支付H5支付是指商户在微信客户端外的移动端网页展示商品或服务，用户在前述页面确认使用微信支付时，商户发起本服务呼起微信客户端进行支付主要用于触屏版的手机浏览器请求微信支付的场景。可以方便的从外部浏览器唤起微信支付开发流程1、用户在商户侧完成下单，使用微信支付进行支付2、由商户后台向微信支付发起下单请求（调用统一下单接口）注：交易类型trade_type=MWEB3、统一下单接口返回支付相关参数给商户后台，如支付跳转url（参数名“mweb_url”），商户通过mweb_url调起微信支付中间页4、中间页进行H5权限的校验，安全性检查（此处常见错误请见下文）5、如支付成功，商户后台会接收到微信侧的异步通知6、用户在微信支付收银台完成支付或取消支付，返回商户页面（默认为返回支付发起页面）7、商户在展示页面，引导用户主动发起支付结果的查询8、商户后台判断是否接到收微信侧的支付结果通知，如没有，后台调用订单查询接口确认订单状态9、展示最终的订单支付结果给用户相信大家都用过企鹅的sdk吧，那酸爽让人难以接受h5的支付我就不给大家截图了，看调用方式就知道了APP签名结果微信支付类库下载地址：wepay.tar.gz
