Android之Native(原生)支付模式一demo
【腾讯云】校园拼团福利,1核2G服务器10元/月!>>>   

       wemall-mobile是基于WeMall的Android app商城,只需要在原商城目录下上传接口文件即可完成服务端的配置,客户端可定制修改。本文分享Native(原生)支付模式一demo,供技术员参考学习。

wemall官网地址:http://www.wemallshop.com

模式一:商户按固定格式生成链接二维码,用户扫码后调微信

 * 会将productid和用户openid发送到商户设置的链接上,商户收到

 * 请求生成订单,调用统一支付接口下单提交到微信,微信会返回

 * 给商户prepayid。

 * 本例程对应的二维码由native_call_qrcode.php生成;

 * 本例程对应的响应服务为native_call.php;

 * 需要两者配合使用。

native_call.php

<?php
	include_once("./log_.php");
	include_once("../WxPayPubHelper/WxPayPubHelper.php");
	
	//以log文件形式记录回调信息,用于调试
	$log_ = new Log_();

    //使用native通知接口
	$nativeCall = new NativeCall_pub();

	//接收微信请求
	$xml = $GLOBALS['HTTP_RAW_POST_DATA'];
	$log_->log_result($log_name,"【接收到的native通知】:\n".$xml."\n");
	$nativeCall->saveData($xml);
	
	if($nativeCall->checkSign() == FALSE){

 * 微信支付帮助库
 * ====================================================
 * 接口分三种类型:
 * 【请求型接口】--Wxpay_client_
 * 		统一支付接口类--UnifiedOrder
 * 		订单查询接口--OrderQuery
 * 		退款申请接口--Refund
 * 		退款查询接口--RefundQuery
 * 		对账单接口--DownloadBill
 * 		短链接转换接口--ShortUrl
 * 【响应型接口】--Wxpay_server_
 * 		通用通知接口--Notify
 * 		Native支付——请求商家获取商品信息接口--NativeCall
 * 【其他】
 * 		静态链接二维码--NativeLink
 * 		JSAPI支付--JsApi
 * =====================================================
 * 【CommonUtil】常用工具:
 * 		trimString(),设置参数时需要用到的字符处理函数
 * 		createNoncestr(),产生随机字符串,不长于32位
 * 		formatBizQueryParaMap(),格式化参数,签名过程需要用到
 * 		getSign(),生成签名
 * 		arrayToXml(),array转xml
 * 		xmlToArray(),xml转 array
 * 		postXmlCurl(),以post方式提交xml到对应的接口url
 * 		postXmlSSLCurl(),使用证书,以post方式提交xml到对应的接口url
