本文介绍微信支付中订单查询功能的实现。

作者：方倍工作室

地址：http://www.cnblogs.com/txw1958/p/wxpay-order-query.html

一、订单查询

因为某一方技术的原因，可能导致商户在预期时间内都收不到最终支付通知，此时商户可以通过该API来查询订单的详细支付状态。

订单查询API的URL为：

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

URL中的参数只包含目前微信公众平台凭证access_token，而订单查询的真正数据是放在PostData中的，格式如下：

<span>{
    </span>"appid" : "wwwwb4f85f3a797777",
    "package" : "out_trade_no=11122&partner=1900090055&sign=4e8d0df3da0c3d0df38f",
    "timestamp" : "1369745073",
    "app_signature" : "53cca9d47b883bd4a5c85a9300df3da0cb48565c",
    "sign_method" : "sha1"<span>
}</span>

上述内容参数说明如表所示。

参数	说明
appid	公众平台账户的AppId；
package	查询订单的关键信息数据，包含第三方唯一订单号out_trade_no、财付通商户身仹标识partner（即前文所述的partnerid）、签名sign，其中sign是对参数字典序排序并使用&联合起来，最后加上&key=partnerkey（唯一分配），进行md5运算，再转成全大写，最终得到sign
timestamp	linux时间戳；
app_signature	根据支付签名（paySign）生成方法中所讲的签名方式生成的，参加签名字段为：appid、appkey、package、timestamp；
sign_method	签名方法（不计入签名生成）；

二、实现细节

1. 获得access token

这个很容易，参考微信公众平台开发(26) ACCESS TOKEN

代码如下：

<span>1</span> <span>$appid</span> = "wx0000000000000000"<span>;
</span><span>2</span> <span>$appsecret</span> = "e76050733c695748537fc4d4c21d0e2c"<span>;
</span><span>3</span> <span>$url</span> = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=<span>$appid</span>&secret=<span>$appsecret</span>"<span>;
</span><span>4</span> <span>$result</span> = https_request(<span>$url</span><span>);
</span><span>5</span> <span>$jsoninfo</span> = json_decode(<span>$result</span>, <span>true</span><span>);
</span><span>6</span> <span>$access_token</span> = <span>$jsoninfo</span>["access_token"];

2. 参数生成

appid: 直接赋值

timestamp：程序直接获取

<span>$timestamp</span> = <span>time</span>();

sign_method：这里为sha1

难点1：package 值的获得

先要获得sign

sign是out_trade_no，partner，key(partnerkey)三项信息的字典序排序，再MD5运算，再转为大写

<span>$sign</span>= <span>strtoupper</span>(<span>md5</span>("out_trade_no=JfuKdiBig4zZnE4n&partner=1234567890&key=ebf5cf381de2d716d432bfda34fa9e57"));

package 是查询订单的关键信息数据，包含第三方唯一订单号 out_trade_no、财付通商户身仹标识 partner（即前文所述的 partnerid）、签名 sign

<span>$package</span> = "out_trade_no=JfuKdiBig4zZnE4n&partner=1234567890&sign=".<span>$sign</span>;

难点2：获得app_signature

app_signature 依然是根据支付签名（paySign）生成方法中所讲的签名方式生成的，参加签名字段为：appid、appkey、package、timestamp；

<span>$obj</span>['appid']          = "wx0000000000000000"<span>;
</span><span>$obj</span>['appkey']         = "8mruTNOGeX8OVUlIYxIyw6kxCRvdJENpWpw8mruTNOGeX8OVUlIYxIyw6kxCRvdJENpWpw8mruTNOGeX8OVUlIYxIyw6kxCRvdJENpWpw8mruTNOGeX8OVUlIYxIyw6k"<span>;
</span><span>$obj</span>['package']        = <span>$package</span><span>;
</span><span>$obj</span>['timestamp']      = <span>$timestamp</span><span>;
</span><span>$WxPayHelper</span> = <span>new</span><span> WxPayHelper();
</span><span>//</span><span>get_biz_sign函数受保护，需要先取消一下，否则会报错</span>
<span>$app_signature</span>  = <span>$WxPayHelper</span>->get_biz_sign(<span>$obj</span>);

这样各项参数都获得了

3.提交查询

<span>$jsonmenu</span> = '<span>
{
    "appid" : "wx0000000000000000",
    "package" : "</span>'.<span>$package</span>.'<span>",
    "timestamp" : "</span>'.<span>$timestamp</span>.'<span>",
    "app_signature" : "</span>'.<span>$app_signature</span>.'<span>",
    "sign_method" : "sha1"
}
</span>'<span>;

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

完整代码如下所示：

</span><span>53</span>     <span>return</span> <span>$output</span><span>;
</span><span>54</span> }

三、订单结果

上述程序执行后，获得订单结果如下

<span>{
    </span>"errcode": 0<span>,
    </span>"errmsg": "ok"<span>,
    </span>"order_info"<span>: {
        </span>"ret_code": 0<span>,
        </span>"ret_msg": ""<span>,
        </span>"input_charset": "GBK"<span>,
        </span>"trade_state": "0"<span>,
        </span>"trade_mode": "1"<span>,
        </span>"partner": "1234567890"<span>,
        </span>"bank_type": "CMB_FP"<span>,
        </span>"bank_billno": "201405273540085997"<span>,
        </span>"total_fee": "1"<span>,
        </span>"fee_type": "1"<span>,
        </span>"transaction_id": "1218614901201405273313473135"<span>,
        </span>"out_trade_no": "JfuKdiBig4zZnE4n"<span>,
        </span>"is_split": "false"<span>,
        </span>"is_refund": "false"<span>,
        </span>"attach": ""<span>,
        </span>"time_end": "20140527194139"<span>,
        </span>"transport_fee": "0"<span>,
        </span>"product_fee": "1"<span>,
        </span>"discount": "0"<span>,
        </span>"rmb_total_fee": ""<span>
    }
}</span>
