PHP micro-Letter Js-sdk Payment Interface Class Usage example _php tips

This article describes the PHP version of micro-letter Js-sdk Payment Interface class usage. Share to everyone for your reference, specific as follows:

This payment class is based on official documentation changes! The main implementation of the generation of JS API, native package signature package and native response of the XML format data. Comments are marked with the intent of each method. Due to the package package signature, slightly complex, this should spend time to their own to see and log out of the file to one by one contrast! Of course, as long as you use the tutorial class, set the corresponding parameters can be the correct generation of package parameters, etc.

<?php if (isset ($ARGC) && $argc >= 1 && $argv [0] = = __file__) {//initialization of pay necessary information $pay = new WeChat Pay (Array (wechatpay::appid => ' wx99dabzpiuq83985b8 ', Wechatpay::appsercer => ' ac12e7e4abaer63hkoa0cc36a9663 FA ', Wechatpay::P artnerkey => ' bae4sfa3562rsfaq23s2045 ', Wechatpay::P artnerid => ' 1268969802 ', WechatPay ::P aysignkey => ' 9fqsxb3pk4ivocec4ycquy5zecs9leemjf2nn4b4ykooxpwaqdfwmezkt8onlbyawcut ', WechatPay::SIGNTYPE =

  Set package necessary parameters Jsapi native are universal $pay->setparams (Wechatpay::bank_type, "WX");
  $pay->setparams (wechatpay::body, "test");
  $pay->setparams (wechatpay::P artner, $pay->partnerid);
  $pay->setparams (Wechatpay::out_trade_no, Commonutil::createnoncestr ());
  $pay->setparams (Wechatpay::total_fee, "1");
  $pay->setparams (Wechatpay::fee_type, "1");
  $pay->setparams (Wechatpay::timestamp, Time ());
  $pay->setparams (Wechatpay::notify_url, "http://www.demo.com/notify"); $Pay->setparams (Wechatpay::spbill_create_ip, "127.0.0.1");
  $pay->setparams (Wechatpay::input_charset, "UTF-8");
  JSAPI signed JSON Print_r ($pay->createjsapipackage ());
  Generate native XML Print_r ($pay->createnativepackage ());
Generate native URL Print_r ($pay->createnativeurl ("9701"));

 }

JS API generated Package signature Package parameters:

{"
  appId": "Wx9998ff5f4dede5b7",
  "package": "Bank_type=wx&body=test&fee_type=1&input_charset =utf-8&notify_url=http%3a%2f%2fwww.demo.com%2fnotify&out_trade_no=vf5qsswtu0hc2loh&partner= wx9998ff5f4dede5b7&spbill_create_ip=127.0.0.1&timestamp=1409295711&total_fee=1&sign= Fee0167bd0d89a88bf6850590ea889b6 ",
  " TimeStamp ": 1409295711,
  " noncestr ":" Vf5qsswtu0hc2loh ",
  " paysign ":" f816264c750923863c370a1739640244b0c2d39c ","
  Signtype ":" SHA1 "
}

XML format for Native responses:

<xml>
  <appid><![ cdata[wx9998ff5f4dede5b7]]></appid>
  <Package>
    <![ cdata[bank_type=wx&body=test&fee_type=1&input_charset=utf-8&notify_url=http%3a%2f% 2fwww.demo.com%2fnotify&out_trade_no=gdl3what4saldead&partner=wx9998ff5f4dede5b7&spbill_create_ip= 127.0.0.1&timestamp=1409296124&total_fee=1&sign=bf949b85570644b939b369fd44b0c4a9]]>
  </ package>
  <TimeStamp>1409296124</TimeStamp>
  <noncestr><![ cdata[gdl3what4saldead]]></noncestr>
  <RetCode>0</RetCode>
  <reterrmsg><![ Cdata[ok]]></reterrmsg>
  <appsignature><![ Cdata[ca4a2467b817a62c38a9801fcf451f51692027bf]]></appsignature>
  <signmethod><![ Cdata[sha1]]></signmethod>
</xml>

URL link for native:

weixin://wxpay/bizpayurl?appid=wx9998ff5f4dede5b7&noncestr=vy7cva6mtvrc1bvq&productid=9701&sign= 43508b65b50e1d7e1089be66d55a709469155d73&timestamp=1409296323

Either way, we have to use SetParams to set the necessary initialization parameters and commodity prices and status!
