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"/> <html> <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>钱</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){
//这是自己的业务逻辑,理论上有prepayid之后,自己数据库里面就应该有一张订单,未支付的订单 $data[‘uid‘]=$uid; $data[‘mustpay‘]=$mustpay; $data[‘prepay_id‘]=$prepay_id; $data[‘goods‘]=$sel;//选择的商品,目前是select的值 $data[‘desc‘]=$desc; $data[‘product_id‘] = $product_id; $data[‘openid‘]= $param [‘openid‘]; $data[‘trade_type‘]="JSAPI"; $data[‘time‘]=time(); $data[‘body‘]= $jssdk->parameters[‘body‘]; $data[‘out_trade_no‘]=$jssdk->parameters[‘out_trade_no‘]; M ( "mall_order" )->add($data); } //JSSDK 用户支付完成后的一些系统操作 /* $param1 [‘dcnum‘] = $jssdk->parameters[‘out_trade_no‘]; $param1 [‘openid‘] = $jssdk->parameters[‘openid‘]; $ajaxurl = addons_url ( ‘Jssdk://Jssdk/orderpaid‘, $param1 ); //用户支付完成后,在微信支付返回alarmnotify之前(不保证时序),可以通过ajax调用,进行一些预处理操作 $jsApiParameters = substr($jsApiParameters,1,-1).",success: function (res) { // 支付成功后的js回调函数 }"; */ $param1 [‘openid‘] = $jssdk->parameters[‘openid‘]; $ajaxurl= addons_url ( ‘Member://Member/show_info‘ ,$param); $this->assign("ajaxurl",$ajaxurl); //向页面传整理好的调起支付参数 $this->assign("jsApiParameters",$jsApiParameters); //向页面传整理好的调起支付参数 $this->display (); }
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) public ‘fee_type‘ => string ‘CNY‘ (length=3) public ‘is_subscribe‘ => string ‘Y‘ (length=1) public ‘mch_id‘ => string ‘1233453902‘ (length=10) public ‘nonce_str‘ => string ‘ma4l5345345rzZN‘ (length=16) public ‘openid‘ => string ‘oV345345345calllGlBdwRU1BjY‘ (length=28) public ‘out_trade_no‘ => string ‘outtradeno14234324‘ (length=20) public ‘result_code‘ => string ‘SUCCESS‘ (length=7) public ‘return_code‘ => string ‘SUCCESS‘ (length=7) public ‘sign‘ => string ‘735C329E5234234796E723728969‘ (length=32) public ‘time_end‘ => string ‘2034534504523‘ (length=14) public ‘total_fee‘ => string ‘1‘ (length=1) public ‘trade_type‘ => string ‘JSAPI‘ (length=5) public ‘transaction_id‘ => string ‘13453453453422835‘ (length=28) */ $result = xmlToArray($post_data); $resp = true; $respdata["return_code"] = "SUCCESS"; $respdata["return_msg"] = ""; $map["appid"] = $result["appid"]; $map["mch_id"] = $result["mch_id"]; $map["openid"] = $result["openid"]; $map["out_trade_no"] = $result["out_trade_no"]; if($result[‘result_code‘]==‘SUCCESS‘ && $result[‘return_code‘]==‘SUCCESS‘){ //支付成功了 //进行业务处理 echo "success"; } }
四,微信支付类

有问题再单独开日志吧...感觉不是很顺畅..比支付宝差远了
