微信支付开发

微信支付真心最坑爹的支付,总结一下

一:前台页面

<include file="Public/mobile_head"/>

    <meta http-equiv="content-type" content="text/html;charset=utf-8"/>
    <meta name="viewport" content="width=device-width, initial-scale=1"/> 
    <title>微信支付样例-支付</title>
    <script type="text/javascript">
    //调用微信JS api 支付
    function jsApiCall()
    {
        WeixinJSBridge.invoke(
            getBrandWCPayRequest,
            {$jsApiParameters},
            function(res){
                WeixinJSBridge.log(res.err_msg);
                //alert(res.err_code+res.err_desc+res.err_msg);
                var html="您已成功购买{$month_time}个月月卡,立刻获赠游戏币{$coin_award}。游戏UID:{$uid}<br>月卡到期时间: {$month_card_overtime}<br><button class=‘blue_btn mb_10 ‘>确定</button>";
                $.Dialog.sure(html);//成功调用 提示一秒后自动关闭
                $(".dialog_sure").click(function(){
                    WeixinJSBridge.call(closeWindow);
                });
                
            }
        );
    }

    function callpay()
    {
        if (typeof WeixinJSBridge == "undefined"){
            if( document.addEventListener ){
                document.addEventListener(WeixinJSBridgeReady, jsApiCall, false);
            }else if (document.attachEvent){
                document.attachEvent(WeixinJSBridgeReady, jsApiCall); 
                document.attachEvent(onWeixinJSBridgeReady, jsApiCall);
            }
        }else{
            jsApiCall();
        }
    }


    
    </script>
</head>
<body>
    <br/>
    <font color="#9ACD32"><b>该笔订单支付金额为<span style="color:#f00;font-size:50px">{$mustpay/100}元</span></b></font><br/><br/>
    <div align="center">
        <button style="width:210px; height:50px; border-radius: 15px;background-color:#FE6714; border:0px #FE6714 solid; cursor: pointer;  color:white;  font-size:16px;" type="button" onclick="callpay()" >立即支付</button>
    </div>
</body>
</html>

两个问题

(1)$jsApiParameters参数要对,包含noticestr,stamp,prepayid等,不能丢失,否则付款按钮不能点击

(2)WeixinJSBridge.call(closeWindow);这是微信的关闭当前页面,不然支付完成还会返回到这里

二.后台php

    function index() {
        if(IS_POST){
      /**前台参数post处理部分 略***/
        }
        //用的是weiphp 主要是要获取openid
        $param [‘token‘] = get_token ();
        $param [‘openid‘] = get_openid ();
        $config = getAddonConfig ( ‘Jssdk‘ );
        $appid = $config[‘APPID‘];
        $secret = $config[‘APPSECRET‘];
        //$id = 1;                                            //如有插件中数据id,分享url中应加入id参数
        //$url = addons_url ( ‘WxPay://WxPay/payorder‘, $param );  //分享的url需要和WeixinAddonModel中的组装回复url保持相同
        //$this->assign ( ‘share_url‘, $url );
        
        $jssdk = new JSSDK($appid, $secret);
        $jssdk->debug = false;    //启用本地调试模式,将官方的两个json文件放到入口文件index.php同级目录即可!
        $signPackage = $jssdk->GetSignPackage();
        
        $this->assign ( ‘signPackage‘, $signPackage );
        
        //微信支付部分
        //此处可以动态获取数据库中的MCHID和KEY
       /***************************/ 
    //这部分自行配置 /***************************/ $jssdk->MCHID =$config[‘MCHID‘]; // 动态MCHID;微信支付分配的商户号 $jssdk->KEY = $config[‘KEY‘]; // 动态KEY; $jssdk->SSLCERT_PATH = $config[‘SSLCERT_PATH‘]; // 动态KEY; $jssdk->SSLKEY_PATH = $config[‘SSLKEY_PATH‘]; // 动态KEY; $jssdk->APPID = $config[‘APPID‘]; // 动态KEY; $jssdk->APPSECRET = $config[‘APPSECRET‘]; // 动态KEY; //=========步骤2:使用统一支付接口,获取prepay_id============ //使用统一支付接口 $jssdk->parameters[‘openid‘] = $param [‘openid‘]; //trade_type=JSAPI,此参数必传,用户在商户appid下的唯一标识。 $jssdk->parameters[‘body‘]="订单支付"; //商品或支付单简要描述 $jssdk->parameters[‘out_trade_no‘] = "outtradeno".time(); //商户系统内部的订单号,32个字符内、可包含字母,不可重复 $jssdk->parameters[‘total_fee‘] = 1; //此处单位为分 出现小数点接口报错必须是整数 $jssdk->parameters[‘notify_url‘] = ‘xxxxxxxxxxxxxxxxxxxxxxxxxxxxx 带http的地址 就下面那个alarmnotify方法‘; //接收微信支付异步通知回调地址 $jssdk->parameters[‘trade_type‘] = "JSAPI"; //取值如下:JSAPI,NATIVE,APP $jssdk->parameters[‘spbill_create_ip‘] = get_client_ip(); //APP和网页支付提交用户端ip,Native支付填调用微信支付API的机器IP。 //以下非必填参数根据需要添加 //$jssdk->parameters[‘device_info‘] = "013467007045764"; //微信支付分配的终端设备号,商户自定义 $jssdk->parameters[‘detail‘] = $desc; //商品名称明细列表 //$jssdk->parameters[‘attach‘] = "说明"; //附加数据,在查询API和支付通知中原样返回,该字段主要用于商户携带订单的自定义数据 //$jssdk->parameters[‘fee_type‘] = "CNY"; //符合ISO 4217标准的三位字母代码,默认人民币:CNY $jssdk->parameters[‘time_start‘] = time(); //订单生成时间,格式为yyyyMMddHHmmss //$jssdk->parameters[‘time_expire‘] = "20091227091010"; //订单失效时间,格式为yyyyMMddHHmmss //$jssdk->parameters[‘goods_tag‘] = "WXG"; //商品标记,代金券或立减优惠功能的参数 $jssdk->parameters[‘product_id‘] = $product_id; //trade_type=NATIVE,此参数必传。此id为二维码中包含的商品ID,商户自行定义。 $prepay_id = $jssdk->getPrepayId(); //微信生成的预支付回话标识,用于后续接口调用中使用,该值有效期为2小时 $jssdk->prepay_id = $prepay_id ; //微信生成的预支付回话标识,用于后续接口调用中使用,该值有效期为2小时 //=========步骤3:使用jsapi调起支付============ $jsApiParameters = $jssdk->getParameters(); //=========步骤N:当有prepayid再生成订单用户自己生成订单============ if($prepay_id){

三,通知处理

 //支付完成接收支付服务器返回通知
    public function alarmnotify(){
        $post_data = $GLOBALS [‘HTTP_RAW_POST_DATA‘];
        \Think\Log::record ( "alarmnotify". $post_data  );
                //log的内容大体如下
        /*
          public ‘appid‘ => string ‘w345345345a83a9b9b9‘ (length=18)
          public ‘bank_type‘ => string ‘CFT‘ (length=3)
          public ‘cash_fee‘ => string ‘1‘ (length=1)

        $result = xmlToArray($post_data);
        $resp = true;
        $respdata["return_code"] = "SUCCESS";

            //支付成功了
            //进行业务处理
            
            echo "success";
        }
        


    }    

四,微信支付类

<?php

/**


类是uctoo写的,貌似现在的类更好,我反正能用就行,


 * 官方文档:http://mp.weixin.qq.com/wiki/7/aaa137b55fb2e0456bf8dd9148dd613f.html
 * 微信支付:http://pay.weixin.qq.com/wiki/doc/api/index.php?chapter=9_1#
 * 官方示例:http://demo.open.weixin.qq.com/jssdk/sample.zip
 * 
 * 微信JSSDK类,主要修改了保存会话信息机制,示例中使用的是文件,这里使用了ThinkPHP的缓存机制,参考官方提供的示例文档 
 * 新增了调试模式,调用示例如下:
 *         $jssdk = new JSSDK(C(‘WX_APPID‘), C(‘WX_SECRET‘));
 *      $jssdk->debug = true;    //启用本地调试模式,将官方的两个json文件放到入口文件index.php同级目录即可!
 *       $signPackage = $jssdk->GetSignPackage();
 * @命名空间版本
