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：

rush:PHP;"> { "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：

cope="col">参数用户的OpenId，这个已经放在最终支付结果通知的PostData里了；Trade_no提示信息，比如“该商品已退款”；生成方法中所讲的签名方式生成的，参加签名字段为：appid、appkey、openid、transid、out_Trade_no、deliver_timestamp、deliver_status、deliver_msg；方法（不计入签名生成）；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

rush:PHP;"> include_once("WxPayHelper.php");

//1. 获取access token
$appid = "wx0000000000000000";
$appsecret = "e76050733ce76050733ce76050733cdd";
$url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=$appid&secret=$appsecret";
$result = https_request($url);
$jsoninfo = json_decode($result,true);
$access_token = $jsoninfo["access_token"];

//2.准备参数
$deliver_timestamp = time();
//2.1构造最麻烦的app_signature
$obj['appid'] = $appid;
$obj['appkey'] = "8mruTNOGeX8OVUlIYxIyw6kxCRvdJENpWpw8mruTNOGeX8OVUlIYxIyw6kxCRvdJENpWpw8mruTNOGeX8OVUlIYxIyw6kxCRvdJENpWpw8mruTNOGeX8OVUlIYxIyw6k";
$obj['openid'] = "o0pk9uIVnlY-fJkzFKEbQ6LJ4cFc";
$obj['transid'] = "1218614901201405273313473135";
$obj['out_trade_no'] = "JfuKdiBig4zZnE4n";
$obj['deliver_timestamp'] = $deliver_timestamp;
$obj['deliver_status'] = "1";
$obj['deliver_msg'] = "ok";

$WxPayHelper = new WxPayHelper();
//get_biz_sign函数受保护，需要先取消一下，否则会报错
$app_signature = $WxPayHelper->get_biz_sign($obj);

//3. 将构造的json提交给微信服务器，查询
$jsonmenu = '
{
"appid" : "'.$obj['appid'].'","openid" : "'.$obj['openid'].'","transid" : "'.$obj['transid'].'","out_Tradeno" : "'.$obj['outTrade_no'].'","deliver_timestamp" : "'.$deliver_timestamp.'","deliver_status" : "'.$obj['deliver_status'].'","deliver_msg" : "'.$obj['deliver_msg'].'","app_signature" : "'.$app_signature.'","sign_method" : "sha1"
}';

$url = "https://api.weixin.qq.com/pay/delivernotify?access_token=".$access_token;
$result = https_request($url,$jsonmenu);
var_dump($result);

function https_request($url,$data = null){
$curl = curl_init();
curl_setopt($curl,CURLOPT_URL,$url);
curl_setopt($curl,CURLOPT_SSL_VERIFYPEER,FALSE);
curl_setopt($curl,CURLOPT_SSL_VERIFYHOST,FALSE);
if (!empty($data)){
curl_setopt($curl,CURLOPT_POST,1);
curl_setopt($curl,CURLOPT_POSTFIELDS,$data);
}
curl_setopt($curl,CURLOPT_RETURNTRANSFER,1);
$output = curl_exec($curl);
curl_close($curl);
return $output;
}
