微信支付开发订单查询实例_php实例

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：

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

2. 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;
$WxPayHelper->get_biz_sign($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：

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
$timestamp = time();
$sign= strtoupper(md5("out_trade_no=JfuKdiBig4zZnE4n&partner=1234567890&key=asdfasdfasdfasdfasdfasdfasdfasdf"));
$package = "out_trade_no=JfuKdiBig4zZnE4n&partner=1234567890&sign=".$sign;

//2.1构造最麻烦的app_signature
$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);

//3. 将构造的json提交给微信服务器，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);

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;
}

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。
