1. Bestellabfrage

Aus technischen Gründen kann es sein, dass der H?ndler die endgültige Zahlungsbenachrichtigung nicht innerhalb der erwarteten Zeit erh?lt. Zu diesem Zeitpunkt kann der H?ndler den detaillierten Zahlungsstatus der Bestellung abfragen über diese API.

Die URL der Bestellabfrage-API lautet:

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

Die Parameter in der Die URL enth?lt derzeit nur die Anmeldeinformationen der ?ffentlichen WeChat-Plattform access_token und die tats?chlichen Daten der Bestellabfrage werden in PostData abgelegt. Das Format lautet wie folgt:

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

Die oben genannten Inhaltsparameter werden in der angezeigten Tabelle erl?utert.

二、實現(xiàn)細節(jié)

1. 獲得access token

這個很容易，參考微信公眾平臺開發(fā)(26) ACCESS TOKEN

代碼如下：

$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. 參數(shù)生成

appid: 直接賦值

timestamp：程序直接獲取

$timestamp = time();

sign_method：這里為sha1

難點1：package 值的獲得

先要獲得sign

sign是out_trade_no，partner，key(partnerkey)三項信息的字典序排序，再MD5運算，再轉為大寫

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

package 是查詢訂單的關鍵信息數(shù)據(jù)，包含第三方唯一訂單號 out_trade_no、財付通商戶身仹標識 partner（即前文所述的 partnerid） 、簽名 sign

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

難點2：獲得app_signature

app_signature 依然是根據(jù)支付簽名（paySign）生成方法中所講的簽名方式生成的，參加簽名字段為：appid、appkey、package、timestamp；

$obj['appid']          = "wx0000000000000000";
$obj['appkey']         = "8mruTNOGeX8OVUlIYxIyw6kxCRvdJENpWpw8mruTNOGeX8OVUlIYxIyw6kxCRvdJENpWpw8mruTNOGeX8OVUlIYxIyw6kxCRvdJENpWpw8mruTNOGeX8OVUlIYxIyw6k";
$obj['package']        = $package;
$obj['timestamp']      = $timestamp;
$WxPayHelper->get_biz_sign($obj);

這樣各項參數(shù)都獲得了

3.提交查詢

$jsonmenu = '{
    "appid" : "wx0000000000000000",
    "package" : "'.$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);

完整代碼如下所示：

include_once("WxPayHelper.php");

//1. 獲取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.準備參數(shù)
$timestamp = time();
$sign= strtoupper(md5("out_trade_no=JfuKdiBig4zZnE4n&partner=1234567890&key=asdfasdfasdfasdfasdfasdfasdfasdf"));
$package = "out_trade_no=JfuKdiBig4zZnE4n&partner=1234567890&sign=".$sign;

//2.1構造最麻煩的app_signature
$obj['appid']          = "wx0000000000000000";
$obj['appkey']         = "8mruTNOGeX8OVUlIYxIyw6kxCRvdJENpWpw8mruTNOGeX8OVUlIYxIyw6kxCRvdJENpWpw8mruTNOGeX8OVUlIYxIyw6kxCRvdJENpWpw8mruTNOGeX8OVUlIYxIyw6k";
$obj['package']        = $package;
$obj['timestamp']      = $timestamp;
$WxPayHelper = new WxPayHelper();
//get_biz_sign函數(shù)受保護，需要先取消一下，否則會報錯
$app_signature  = $WxPayHelper->get_biz_sign($obj);

//3. 將構造的json提交給微信服務器，查詢
$jsonmenu = '
{
 "appid" : "wx0000000000000000",
 "package" : "'.$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、訂單結果

上述程序執(zhí)行后，獲得訂單結果如下

{
    "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": ""
    }
}

各個字段的含義如表所示。

Wenn im Programm ein Fehler vorliegt, wird dieser in errcode und errmsg beschrieben.
