First, generate product information
During the dynamic link payment process, it is the trade of the goods that is made by Mr. Cheng to carry out the payment transaction.
1. Product Information Preparation
The first is to define the name and price of the product, and the transaction number. The code is as follows.
Include_once (".. /wxpaypubhelper/wxpaypubhelper.php "); Use the unified payment interface $unifiedOrder = new Unifiedorder_pub (); Set the unified Payment interface parameters //settings Required Parameters //appid is filled, the merchant does not need to fill in //mch_id, the merchant does not need to fill in the //noncestr, the merchant does not need to fill in the duplicate // Spbill_create_ip has been filled, merchants do not need to fill in//sign, merchants do not need to fill in the $unifiedOrder->setparameter ("Body", "contribution of a Penny");//Product Description $timeStamp = time (); $out _trade_no = wxpayconf_pub::appid. " $timeStamp "; $unifiedOrder->setparameter ("Out_trade_no", "$out _trade_no");//Merchant Order number $unifiedOrder->setparameter (" Total_fee "," 1 ");//Total Amount $unifiedOrder->setparameter (" Notify_url ", wxpayconf_pub::notify_url);//Notification address $unifiedOrder->setparameter ("Trade_type", "NATIVE");//transaction type //non-mandatory parameters, the merchant can be selected according to the actual situation $unifiedOrder- Setparameter ("Device_info", "100001");//device numberThe above parameters are eventually encapsulated as XML-like parameters
<xml> <body><! [cdata[contribute a penny]]></body> <out_trade_no><! [cdata[100001_1433009089]]></out_trade_no> <total_fee>1</total_fee> <notify_url><! [cdata[http://www.doucube.com/weixin/demo/notify_url.php]]></notify_url> <trade_type><! [cdata[native]]></trade_type> <device_info>100001</device_info> <appid><! [cdata[wx1d065b0628e21103]]></appid> <mch_id>1237905502</mch_id> <spbill_create_ip> <! [cdata[61.129.47.79]]></spbill_create_ip> <nonce_str><! [cdata[gwpdlnn0zlfih21gipjj5z53i7vea8e8]]></nonce_str> <sign><! [cdata[c5a1e210f9b4402d8254f731882f41ac]]></sign></xml>
2. Call a unified payment request
Send the XML above to the unified payment interface
Https://api.mch.weixin.qq.com/pay/unifiedorder
Get the following XML data
<xml> <return_code><! [cdata[success]]></return_code> <return_msg><![ Cdata[ok]]></return_msg> <appid><![ Cdata[wx1d065b0628e21103]]></appid> <mch_id><![ Cdata[1237905502]]></mch_id> <device_info><![ Cdata[100001]]></device_info> <nonce_str><![ Cdata[6u8ovttfuptagsiy]]></nonce_str> <sign><![ Cdata[e84d8bc2331766dd685591f908367ff1]]></sign> <result_code><![ Cdata[success]]></result_code> <prepay_id><![ Cdata[wx20150531020450bb586eb2f70717331240]]></prepay_id> <trade_type><![ Cdata[native]]></trade_type> <code_url><![ Cdata[weixin://wxpay/bizpayurl?pr=dnp7omd]]></code_url> </xml>
So we get a code_url.
The program generates a QR code for the Code_url, which is then provided to the user to sweep
Second, the user pays
1. User Payment
After the
User pays successfully, an XML notification is sent to Notify_url, as follows
<xml> <appid><! [cdata[wx1d065b0628e21103]]></appid> <bank_type><! [cdata[cft]]></bank_type> <cash_fee><! [cdata[1]]></cash_fee> <device_info><! [cdata[100001]]></device_info> <fee_type><! [cdata[cny]]></fee_type> <is_subscribe><! [cdata[n]]></is_subscribe> <mch_id><! [cdata[1237905502]]></mch_id> <nonce_str><! [cdata[gwpdlnn0zlfih21gipjj5z53i7vea8e8]]></nonce_str> <openid><! [cdata[omnkhubtw4ywgngavqw00twk6aum]]></openid> <out_trade_no><! [cdata[100001_1433009089]]></out_trade_no> <result_code><! [cdata[success]]></result_code> <return_code><! [cdata[success]]></return_code> <sign><! [cdata[03eede7ade2abb7916795f37f19a3d13]]></sign> <time_end><! [cdata[20150531020838]]></time_end> <total_fee>1</total_fee> <trade_type><! [cdata[native]]></trade_type> <transaction_id><! [cdata[1002750205201505310187709542]]></transaction_id> </xml>
Notify_url received, and then returned to confirm the success of the message to the server
<xml> <return_code><! [cdata[success]]></return_code></xml>
In this way, a dynamic link native is complete.
