微信支付在THINKPHP中的使用;

第一步:下载官方PHP支付demo

第二步:将文件夹拷贝到thinkphp 框架文件的vendor中;

第三步:稍微修改源码,把PHP脚本改成类的形式;例;

    

class js_api_call extends \Think\Controller{
    public function js_api_call(){
        //构造方法
        vendor ( phpPay.WxPayPubHelper.WxPayPubHelper );
    }

    public function goToPay($payid){
    //使用jsapi接口

    $jsApi = new \JsApi_pub();

    //=========步骤1:网页授权获取用户openid============
    //通过code获得openid
    if (!isset($_GET[code]))
    {
        //触发微信返回code码

        $url = $jsApi->createOauthUrlForCode(WxPayConf_pub::JS_API_CALL_URL,$payid);

        Header("Location: $url"); 
    }else
    {
        //获取code码,以获取openid
        $code = $_GET[code];
        $jsApi->setCode($code);

        $openid = $jsApi->getOpenId();
    }

    //=========步骤2:使用统一支付接口,获取prepay_id============
    //使用统一支付接口
    //获取订单id
    $orderids = $_GET[state];
    $res = M(order)->where(id in (.$orderids.))->select();
    //计算价格 等等
    $totle = 0;
    $tradeNo = null;
    $oid = null;
    foreach($res as $row){
        $totle += $row[totleprice];
        $tradeNo[] = $row[tradeno];
        $oid[] = $row[id];
    }
    $totle = $totle*100;
    $oid = implode(,,$oid);
    $unifiedOrder = new \UnifiedOrder_pub();
    //设置统一支付接口参数
    //设置必填参数
    //appid已填,商户无需重复填写
    //mch_id已填,商户无需重复填写
    //noncestr已填,商户无需重复填写
    //spbill_create_ip已填,商户无需重复填写
    //sign已填,商户无需重复填写
    //自定义订单号,此处仅作举例
    $timeStamp = time();
    $out_trade_no = WxPayConf_pub::APPID."$timeStamp";

    $unifiedOrder->setParameter("openid","$openid");//商品描述
    $unifiedOrder->setParameter("body","$out_trade_no");//商品描述
    $unifiedOrder->setParameter("out_trade_no","$out_trade_no");//商户订单号
    $unifiedOrder->setParameter("total_fee","$totle");//总金额
    $unifiedOrder->setParameter("notify_url",WxPayConf_pub::NOTIFY_URL);//通知地址 
    $unifiedOrder->setParameter("trade_type","JSAPI");//交易类型
    //非必填参数,商户可根据实际情况选填
    //$unifiedOrder->setParameter("sub_mch_id","XXXX");//子商户号  
    //$unifiedOrder->setParameter("device_info","XXXX");//设备号 
    $unifiedOrder->setParameter("attach","$oid");//附加数据
    //$unifiedOrder->setParameter("time_start","XXXX");//交易起始时间
    //$unifiedOrder->setParameter("time_expire","XXXX");//交易结束时间 
    //$unifiedOrder->setParameter("goods_tag","$oid");//商品标记
    //$unifiedOrder->setParameter("openid","XXXX");//用户标识
    //$unifiedOrder->setParameter("product_id","XXXX");//商品ID
    $prepay_id = $unifiedOrder->getPrepayId();
    //=========步骤3:使用jsapi调起支付============
    $jsApi->setPrepayId($prepay_id);

    $jsApiParameters = $jsApi->getParameters();
    echo             <html>
<head>
    <meta http-equiv="content-type" content="text/html;charset=utf-8"/>
    <title>微信安全支付</title>

    <script type="text/javascript">

        //调用微信JS api 支付
        function jsApiCall()
        {
            WeixinJSBridge.invoke(
                "getBrandWCPayRequest",
                .$jsApiParameters.,
                function(res){
                    WeixinJSBridge.log(res.err_msg);
                    //alert(res.err_code+res.err_desc+res.err_msg);
                     window.location.href ="http://demo.yps.deetaa.com/index.php?s=/Wechat/Order/olist.html";
                }
            );
        }

        function callpay()
        {
            if (typeof WeixinJSBridge == "undefined"){
                if( document.addEventListener ){
                    document.addEventListener("WeixinJSBridgeReady", jsApiCall, false);
                }else if (document.attachEvent){
                    document.attachEvent("WeixinJSBridgeReady", jsApiCall);
                    document.attachEvent("WeixinJSBridgeReady", jsApiCall);
                }
            }else{
                jsApiCall();
            }
        }
        callpay();
        </script>
    </head>
    </html>
    ;
    }
}
?>
