php版微信js-sdk支付接口类用法示例

2024-03-11 11:26:02 114

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JSAPI、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

<?php
if(isset($argc)&&$argc>=1&&$argv[0]==__FILE__){
//初始化pay的必要信息
$pay=newWechatPay(array(
WechatPay::APPID=>'wx99dabzpiuq83985b8',
WechatPay::APPSERCER=>'ac12e7e4abaer63hkoa0cc36a9663fa',
WechatPay::PARTNERKEY=>'bae4sfa3562rsfaq23s2045',
WechatPay::PARTNERID=>'1268969802',
WechatPay::PAYSIGNKEY=>'9Fqsxb3PK4IVOCEc4yCquy5zecS9LeeMjF2Nn4B4YKoOxPwaQdFwMezKT8oNlBYaWcuT',
WechatPay::SIGNTYPE=>'sha1',
));
//设置package必要的参数jsapinative都通用
$pay->setParams(WechatPay::BANK_TYPE,"WX");
$pay->setParams(WechatPay::BODY,"test");
$pay->setParams(WechatPay::PARTNER,$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nativeXML
print_r($pay->createNativePackage());
//生成nativeURL
print_r($pay->createNativeUrl("9701"));
}

JSAPI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：

<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>

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！
