微信支付开发发货通知实例

一、发货通知

为了更好地跟踪订单的情况，需要第三方在收到最终支付通知之后，调用发货通知API告知微信后台该订单的发货状态。

发货时间限制：虚拟、服务类24小时内，实物类72小时内。

请在收到支付通知后，按时发货，并使用发货通知接口将相关信息同步到微信后台。若平台在规定时间内没有收到，将视作发货超时处理。

发货通知API的URL为：

https://api.weixin.qq.com/pay/delivernotify?access_token=xxxxxx

URL中的参数只包含目前微信公众平台凭证access_token，而发货通知的真正的数据是放在PostData中的，

格式如下：

{ "appid" : "wwwwb4f85f3a797777", "openid" : "oX99MDgNcgwnz3zFN3DNmo8uwa-w", "transid" : "111112222233333", "out_trade_no" : "555666uuu", "deliver_timestamp" : "1369745073", "deliver_status" : "1", "deliver_msg" : "ok", "app_signature" : "53cca9d47b883bd4a5c85a9300df3da0cb48565c", "sign_method" : "sha1"}

上述内容参数说明如下表所示：

微信公众平台在校验ok之后，会返回数据表明是否通知成功，例如：{"errcode":0,"errmsg":"ok"}如果有异常，会在errcode和errmsg描述出来，如果成功errcode就为0。

二、程序实现

程序中的一些参数来自本博客前面的微信支付开发数据。读者请参照运行
