微信支付开发订单查询实例

前端之家收集整理的这篇文章主要介绍了微信支付开发订单查询实例前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

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:

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。

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;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:

PHP;"> $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

PHP;"> $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

PHP;"> $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

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

get_biz_sign($obj);

这样各项参数都获得了

3.提交查询

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

PHP;"> { "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

404px; width: 672px"> 查询结果状态码,0表明成功,其他表明错误;查询结果出错信息;生成订单package时商户填入的attach; 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。
