First, order inquiry

Due to the technical reasons of one party, the merchant may not receive the final payment notice within the expected time, at which point the merchant can query the detailed payment status of the order through the API.

The URL for the order query API is:

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

The parameters in the URL contain only the current public platform voucher Access_token, and the real data for the order query is placed in PostData, in the following format:

{    "AppID": "wwwwb4f85f3a797777",    "package": "Out_trade_no=11122&partner=1900090055&sign =4e8d0df3da0c3d0df38f ",    " timestamp ":" 1369745073 ",    " app_signature ":" 53cca9d47b883bd4a5c85a9300df3da0cb48565c ",    " Sign_method ":" SHA1 "}

The above content parameter description is shown in the table.

Parameters	Description
AppID	AppID of public platform accounts;
Package	Query the key information data of the order, including the third party unique order number out_trade_no, Tenpay merchant Body Backup identification Partner (that is, Partnerid described above), signed sign, which is the parameter dictionary ordering and use & Union together, and finally add &key=partnerkey (unique Assignment), perform the MD5 operation, and then turn it into uppercase, eventually get sign
Timestamp	Linux time stamp;
App_signature	Based on the signature method described in the payment signature (Paysign) generation methods, participate in the signature field: AppID, Appkey, package, timestamp;
Sign_method	Signature method (not counted as signature generation);

II. details of implementation

1. Get access token

This is easy, refer to public platform development (+) ACCESS TOKEN

The code is as follows:

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 $jsoninfo = Json_decode ($resulttrue); 6 $access _token $jsoninfo ["Access_token"];

2. Parameter generation

AppID: Direct Assignment

Timestamp: Direct access to the program

$timestamp  Time ();

Sign_method: This is SHA1

The acquisition of the difficulty 1:package value

To get sign first

Sign is a dictionary ordering of Out_trade_no,partner,key (Partnerkey) three information, then MD5 operation, then capitalization

$sign Strtoupper (MD5("Out_trade_no=jfukdibig4zzne4n&partner=1234567890&key=ebf5cf381de2d716d432bfda34fa9e57") );

The package is the key information data for the enquiry order, including the third party unique order number out_trade_no, Tenpay merchant Body Backup identification Partner (the Partnerid described above), signed sign

$package = "out_trade_no=jfukdibig4zzne4n&partner=1234567890&sign=". $sign;

Difficulty 2: Get App_signature

App_signature is still generated according to the signature method described in the payment signature (paysign) generation, participating in the signature field: AppID, Appkey, package, timestamp;

$obj [' AppID ']          = "wx0000000000000000"; $obj [' Appkey ']         = "8mrutnogex8ovuliyxiyw6kxcrvdjenpwpw8mrutnogex8ovuliyxiyw6kxcrvdjenpwpw8mrutnogex8ovuliyxiyw6kxcrvdjenpwpw8mrutnogex8ov uliyxiyw6k "; $obj [' Package ']        $package ; $obj [' Timestamp ']      $timestamp ; $WxPayHelper New Wxpayhelper (); // get_biz_sign function is protected, need to cancel first, otherwise it will error $app _signature  $WxPayHelper->get_biz_sign ($obj);

All of these parameters are obtained

3. Submit a Query

$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);

The complete code looks like this:

1 include_once("wxpayhelper.php");2 3 //1. Get access token4 $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"];Ten  One  A //2.

Submit the constructed JSON to the server, querying - $jsonmenu= ' - { in " AppID": "wx0000000000000000", -"Package": "'.$package.'", to"Timestamp": "'.$timestamp.'", +"App_signature": "'.$app _signature.'", - " Sign_method": "SHA1 " the } *'; $ Panax Notoginseng $url= "https://api.weixin.qq.com/pay/orderquery?access_token=".$access _token; - $result= Https_request ($url,$jsonmenu); the Var_dump($result); +  A functionHttps_request ($url,$data=NULL){ the     $curl=curl_init (); +curl_setopt ($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); the     } -curl_setopt ($curl, Curlopt_returntransfer, 1);Wuyi     $output= Curl_exec ($curl); theCurl_close ($curl); -     return $output; Wu}

Third, the order results

Once the above procedure is executed, the result of obtaining the order is as follows

{    "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": ""    }}
