标题: php版微信js-sdk支付接口类用法示例 [打印本页]

作者: 新格网络 时间: 2018-2-14 05:32

         本文实例讲述了php版微信js-sdk支付接口类用法。分享给大家供大家参考，具体如下：
这个支付类是根据官方的文档修改而来！主要实现生成JS API 、Native的package签名包和Native响应的XML格式数据。注释都标上了各方法的用意。由于package包签名，略复杂，这个要自己多花时间去对应去看和log出文件来一一对比！当然只要你用上教程的类，设置好对应的参数就可以正确的生成package参数等
= 1 && $argv[0] == __FILE__) {
  //初始化pay的必要信息
  $pay = new WechatPay(array(
WechatPay::APPID => 'wx99dabzpiuq83985b8',
WechatPay::APPSERCER => 'ac12e7e4abaer63hkoa0cc36a9663fa',
WechatPay:

ARTNERKEY => 'bae4sfa3562rsfaq23s2045',
WechatPay:

ARTNERID => '1268969802',
WechatPay:

AYSIGNKEY => '9Fqsxb3PK4IVOCEc4yCquy5zecS9LeeMjF2Nn4B4YKoOxPwaQdFwMezKT8oNlBYaWcuT',
WechatPay::SIGNTYPE => 'sha1',
  ));
  //设置package 必要的参数 jsapi native都通用
  $pay->setParams(WechatPay::BANK_TYPE, "WX");
  $pay->setParams(WechatPay::BODY, "test");
  $pay->setParams(WechatPay:

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");
  $pay->setParams(WechatPay::INPUT_CHARSET, "UTF-8");
  //JSAPI的签名json
  print_r($pay->createJsApiPackage());
  //生成native XML
  print_r($pay->createNativePackage());
  //生成native URL
  print_r($pay->createNativeUrl("9701"));
}
JS API生成的package签名包参数：
{
  "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"
}
Native 响应的XML格式：




  1409296124

  0



Native的URL链接：
weixin://wxpay/bizpayurl?appid=wx9998ff5f4dede5b7&noncestr=VY7cVA6mtVrc1BVq&productid=9701&sign=43508b65b50e1d7e1089be66d55a709469155d73&timestamp=1409296323
无论哪一种方式，我们都要通过setParams来设置必要初始化参数和商品价格和状态等！
