本文介绍微信支付中订单查询功能的实现。

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：

{

    "appid" : "wwwwb4f85f3a797777",

    "package" : "out_trade_no=11122&partner=1900090055&sign=4e8d0df3da0c3d0df38f",

    "timestamp" : "1369745073",

    "app_signature" : "53cca9d47b883bd4a5c85a9300df3da0cb48565c",

    "sign_method" : "sha1"

}

上述内容参数说明如表所示。

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：

1 $appid = "wx0000000000000000";

2 $appsecret = "e76050733c695748537fc4d4c21d0e2c";

3 $url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=$appid&secret=$appsecret";

4 $result = https_request($url);

5 $jsoninfo = json_decode($result, true);

6 $access_token = $jsoninfo["access_token"];

2. 参数生成

appid: 直接赋值

timestamp：程序直接获取

$timestamp = time();

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

$sign= strtoupper(md5("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

$package = "out_trade_no=JfuKdiBig4zZnE4n&partner=1234567890&sign=".$sign;

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；

$obj[‘appid‘]          = "wx0000000000000000";

$obj[‘appkey‘]         = "8mruTNOGeX8OVUlIYxIyw6kxCRvdJENpWpw8mruTNOGeX8OVUlIYxIyw6kxCRvdJENpWpw8mruTNOGeX8OVUlIYxIyw6kxCRvdJENpWpw8mruTNOGeX8OVUlIYxIyw6k";

$obj[‘package‘]        = $package;

$obj[‘timestamp‘]      = $timestamp;

$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);

这样各项参数都获得了

3.提交查询

$jsonmenu = ‘

{

    "appid" : "wx0000000000000000",

    "package" : "‘.$package.‘",

    "timestamp" : "‘.$timestamp.‘",

    "app_signature" : "‘.$app_signature.‘",

    "sign_method" : "sha1"

}

‘;

$url = "https://api.weixin.qq.com/pay/orderquery?access_token=".$access_token;

$result = https_request($url, $jsonmenu);

var_dump($result);

完整代码如下所示：

 1 include_once("WxPayHelper.php");

 2

 3 //1. 获取access token

 4 $appid = "wx0000000000000000";

 5 $appsecret = "e76050733ce76050733ce76050733cdd";

 6 $url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=$appid&secret=$appsecret";

 7 $result = https_request($url);

 8 $jsoninfo = json_decode($result, true);

 9 $access_token = $jsoninfo["access_token"];

10

11

12 //2.准备参数

13 $timestamp = time();

14 $sign= strtoupper(md5("out_trade_no=JfuKdiBig4zZnE4n&partner=1234567890&key=asdfasdfasdfasdfasdfasdfasdfasdf"));

15 $package = "out_trade_no=JfuKdiBig4zZnE4n&partner=1234567890&sign=".$sign;

16

17 //2.1构造最麻烦的app_signature

18 $obj[‘appid‘]          = "wx0000000000000000";

19 $obj[‘appkey‘]         = "8mruTNOGeX8OVUlIYxIyw6kxCRvdJENpWpw8mruTNOGeX8OVUlIYxIyw6kxCRvdJENpWpw8mruTNOGeX8OVUlIYxIyw6kxCRvdJENpWpw8mruTNOGeX8OVUlIYxIyw6k";

20 $obj[‘package‘]        = $package;

21 $obj[‘timestamp‘]      = $timestamp;

22 $WxPayHelper = new WxPayHelper();

23 //get_biz_sign函数受保护，需要先取消一下，否则会报错

24 $app_signature  = $WxPayHelper->get_biz_sign($obj);

25

26 //3. 将构造的json提交给微信服务器，查询

27 $jsonmenu = ‘

28 {

29     "appid" : "wx0000000000000000",

30     "package" : "‘.$package.‘",

31     "timestamp" : "‘.$timestamp.‘",

32     "app_signature" : "‘.$app_signature.‘",

33     "sign_method" : "sha1"

34 }

35 ‘;

36

37 $url = "https://api.weixin.qq.com/pay/orderquery?access_token=".$access_token;

38 $result = https_request($url, $jsonmenu);

39 var_dump($result);

40

41 function https_request($url, $data = null){

42     $curl = curl_init();

43     curl_setopt($curl, CURLOPT_URL, $url);

44     curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);

45     curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE);

46     if (!empty($data)){

47         curl_setopt($curl, CURLOPT_POST, 1);

48         curl_setopt($curl, CURLOPT_POSTFIELDS, $data);

49     }

50     curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);

51     $output = curl_exec($curl);

52     curl_close($curl);

53     return $output;

54 }

三、订单结果

上述程序执行后，获得订单结果如下

{

    "errcode": 0,

    "errmsg": "ok",

    "order_info": {

        "ret_code": 0,

        "ret_msg": "",

        "input_charset": "GBK",

        "trade_state": "0",

        "trade_mode": "1",

        "partner": "1234567890",

        "bank_type": "CMB_FP",

        "bank_billno": "201405273540085997",

        "total_fee": "1",

        "fee_type": "1",

        "transaction_id": "1218614901201405273313473135",

        "out_trade_no": "JfuKdiBig4zZnE4n",

        "is_split": "false",

        "is_refund": "false",

        "attach": "",

        "time_end": "20140527194139",

        "transport_fee": "0",

        "product_fee": "1",

        "discount": "0",

        "rmb_total_fee": ""

    }

}

各个字段的含义如表所示。

如果程序有误，会在errcode和errmsg描述出来。
