JAVA服务端验证异步通知信息参数示例

//获取支付宝POST过来反馈信息
Map params = new  HashMap();
Map requestParams = request.getParameterMap();
for  (Iterator iter = requestParams.keySet().iterator(); iter.hasNext();) {
    String name = (String) iter.next();
    String[] values = (String[]) requestParams.get(name);
    String valueStr = "" ;
    for  ( int  i = 0 ; i < values.length; i++) {
        valueStr = (i == values.length - 1 ) ? valueStr + values[i]
                    : valueStr + values[i] + "," ;
  }
  //乱码解决，这段代码在出现乱码时使用。
  //valueStr = new String(valueStr.getBytes("ISO-8859-1"), "utf-8");
  params.put(name, valueStr);
 }
//切记alipaypublickey是支付宝的公钥，请去open.alipay.com对应应用下查看。
//boolean AlipaySignature.rsaCheckV1(Map params, String publicKey, String charset, String sign_type)
boolean  flag = AlipaySignature.rsaCheckV1(params, alipaypublicKey, charset, "RSA2" )

PHP服务端SDK生成APP支付订单信息示例

$aop = new  AopClient;
$aop->gatewayUrl = "https://openapi.alipay.com/gateway.do" ;
$aop->appId = "app_id" ;
$aop->rsaPrivateKey = '请填写开发者私钥去头去尾去回车，一行字符串'  ;
$aop->format = "json" ;
$aop->charset = "UTF-8" ;
$aop->signType = "RSA2" ;
$aop->alipayrsaPublicKey = '请填写支付宝公钥，一行字符串' ;
//实例化具体API对应的request类,类名称和接口名称对应,当前调用接口名称：alipay.trade.app.pay
$request = new  AlipayTradeAppPayRequest();
//SDK已经封装掉了公共参数，这里只需要传入业务参数
$bizcontent = "{\"body\":\"我是测试数据\","
                . "\"subject\": \"App支付测试\","
                . "\"out_trade_no\": \"20170125test01\","
                . "\"timeout_express\": \"30m\","
                . "\"total_amount\": \"0.01\","
                . "\"product_code\":\"QUICK_MSECURITY_PAY\""
                . "}" ;
$request->setNotifyUrl( "商户外网可以访问的异步地址" );
$request->setBizContent($bizcontent);
//这里和普通的接口调用不同，使用的是sdkExecute
$response = $aop->sdkExecute($request);
//htmlspecialchars是为了输出到页面时防止被浏览器将关键参数html转义，实际打印到日志以及http传输不会有这个问题
echo htmlspecialchars($response); //就是orderString 可以直接给客户端请求，无需再做处理。

.NET服务端SDK生成APP支付订单信息示例

IAopClient client = new  DefaultAopClient( "https://openapi.alipay.com/gateway.do" , APPID, APP_PRIVATE_KEY, "json" , "1.0" , "RSA2" , ALIPAY_PUBLIC_KEY, CHARSET, false );
//实例化具体API对应的request类,类名称和接口名称对应,当前调用接口名称如：alipay.trade.app.pay
AlipayTradeAppPayRequest request = new  AlipayTradeAppPayRequest();
//SDK已经封装掉了公共参数，这里只需要传入业务参数。以下方法为sdk的model入参方式(model和biz_content同时存在的情况下取biz_content)。
AlipayTradeAppPayModel model = new  AlipayTradeAppPayModel();

//这里和普通的接口调用不同，使用的是sdkExecute
AlipayTradeAppPayResponse response = client.SdkExecute(request);
//HttpUtility.HtmlEncode是为了输出到页面时防止被浏览器将关键参数html转义，实际打印到日志以及http传输不会有这个问题
Response.Write(HttpUtility.HtmlEncode(response.Body));
//页面输出的response.Body就是orderString 可以直接给客户端请求，无需再做处理。
