首页 / 网页编程 / PHP / 微信支付开发订单查询实例

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。
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
timestamplinux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:
$appid = "wx0000000000000000";$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
参数说明
ret_code查询结果状态码,0表明成功,其他表明错误;
ret_msg查询结果出错信息;
input_charset返回信息中的编码方式;
trade_state订单状态,0为成功,其他为失败;
trade_mode交易模式,1为即时到帐,其他保留;
partner财付通商户号,即前文的partnerid;
bank_type银行类型;
bank_billno银行订单号;
total_fee总金额,单位为分;
fee_type币种,1为人民币;
transaction_id财付通订单号;
out_trade_no第三方订单号;
is_split是否分账,false为无分账,true为有分账;
is_refund是否退款,false为无退款,ture为退款;
attach商户数据包,即生成订单package时商户填入的attach;
time_end支付完成时间;
transport_fee物流费用,单位为分;
product_fee物品费用,单位为分;
discount折扣价格,单位为分;
rmb_total_fee换算成人民币之后的总金额,单位为分,一般看total_fee即可。
如果程序有误,会在errcode和errmsg描述出来。
以上就是对微信支付开发中查询功能的资料整理,希望能帮到微信开发支付的朋友。
