Php微信小程序支付

官方参数

文档地址&＃xff1a;https://developers.weixin.qq.com/miniprogram/dev/api/open-api/payment/wx.requestPayment.html

小程序中代码

如果说你的小程序中有其他登陆方式&＃xff0c;比如手机登陆&＃xff0c;那么支付的时候就要先去获取用户的openid

// 获取用户的openid
get_user_openid:function(){let that &＃61; this;let openid &＃61; app.globalData.openid;if (openid){run_pay(that);}else{ // 先获取用户openidapp.get_user_openid(function (data) {run_pay(that);})}
},


下面看看发起支付

// 立即支付
function run_pay(that){let bookReadData &＃61; wx.getStorageSync(&＃39;bookReadData&＃39;);let channel &＃61; app.globalData.QRXS_CHANNEL;let bid &＃61; bookReadData.bid;app.httpRequest(config.payOrderBe, {}, function (data) {let product &＃61; &＃39;开通畅读卡&＃39;;var postdata &＃61; {product: product,detail: product,fee: that.data.pay_price * 100,reward: that.data.reward,bid: bid,channel: channel,timestamp: data.timestamp,nonceStr: data.nonceStr,signature: data.signature,}postdata[&＃39;openid&＃39;] &＃61; app.globalData.openidpostdata[&＃39;sign&＃39;] &＃61; md5.md5(postdata.product &＃43; postdata.detail &＃43; postdata.fee &＃43; postdata.timestamp &＃43; postdata.reward &＃43; config.APP_KEY);app.httpRequest(config.payOrder, postdata, function (data) {var res_data &＃61; data;var nonceStr &＃61; res_data.nonceStr;var outtradeno &＃61; res_data.OutTradeNo;var wxpackage &＃61; res_data.package;var paysign &＃61; res_data.paySign;var timestamp &＃61; res_data.timestamp;wx.requestPayment({&＃39;timeStamp&＃39;: timestamp,&＃39;nonceStr&＃39;: nonceStr,&＃39;package&＃39;: wxpackage,&＃39;signType&＃39;: &＃39;MD5&＃39;,&＃39;paySign&＃39;: paysign,&＃39;success&＃39;: function (res) {console.log(res)//成功应该要刷新用户信息&＃xff0c;还有当前章节是否开通if (res.errMsg &＃61;&＃61;&＃61; "requestPayment:ok") {if (that.data.show_back &＃61;&＃61;&＃61; 1) {app.getUserData(); // 刷新用户信息wx.redirectTo({url: &＃39;/pages/buyCard/buyStatus/buyStatus?type&＃61;1&＃39;,})} else {wx.switchTab({url: &＃39;/pages/my/my&＃39;})}}},&＃39;fail&＃39;: function (res) {console.log(res)if (res.errMsg &＃61;&＃61; "requestPayment:fail cancel") {wx.redirectTo({url: &＃39;/pages/buyCard/buyStatus/buyStatus?type&＃61;0&＃39;,})}},&＃39;complete&＃39;: function (res) {console.info(&＃39;complete&＃39;);}});});})
}


后端发起支付代码

发起支付第一步&＃xff0c;获取支付所需信息&＃xff0c;
跟网页端支付差不多

// 获取支付所需签名等
function wx_begin(){include_once "Application/Xcx4/ORG/WxPaySync/jssdk.php";$jssdk &＃61; new \JSSDK(&＃39;wxabxxxxxb66bd&＃39;, &＃39;647474836xxxxxxxxxxxxxxxx9221d724&＃39;);$signPackage &＃61; $jssdk->GetSignPackage();return_json_data(1,&＃39;ok&＃39;,$signPackage);}

发起支付

}


支付回调


//v3.0版微信支付回调接口
public function wx(){include_once "Application/Xcx4/ORG/WxPaySync/WxPayPubHelper.php";//使用通用通知接口$notify &＃61; new \Notify_pub();//存储微信的回调$xml &＃61; $GLOBALS[&＃39;HTTP_RAW_POST_DATA&＃39;];$notify->saveData($xml);//验证签名&＃xff0c;并回应微信。//对后台通知交互时&＃xff0c;如果微信收到商户的应答不是成功或超时&＃xff0c;微信认为通知失败&＃xff0c;//微信会通过一定的策略&＃xff08;如30分钟共8次&＃xff09;定期重新发起通知&＃xff0c;//尽可能提高通知的成功率&＃xff0c;但微信不保证通知最终能成功。if($notify->checkSign() &＃61;&＃61; FALSE){$notify->setReturnParameter("return_code","FAIL");//返回状态码$notify->setReturnParameter("return_msg","签名失败");//返回信息}else{$notify->setReturnParameter("return_code","SUCCESS");//设置返回码}if($notify->checkSign() &＃61;&＃61; true){$out_trade_no &＃61; $notify->data["out_trade_no"];//订单号$trade_no &＃61; $notify->data["transaction_id"];//微信支付订单号$result_code &＃61; $notify->data["result_code"];//业务结果$bank_type &＃61; $notify->data["bank_type"];//付款银行$is_subscribe &＃61; $notify->data["is_subscribe"];//是否关注公众号$openid &＃61; $notify->data["openid"];///支付成功 业务逻辑操作 echo &＃39;&＃39;;}else{echo &＃39;&＃39;;}
