### 1. 官方文档 ###

app支付：[https://docs.open.alipay.com/204/105297/][https_docs.open.alipay.com_204_105297]

服务端sdk下载及实例：[https://docs.open.alipay.com/54/106370][https_docs.open.alipay.com_54_106370]

### 2. 大概流程 ###

a. 创建应用，拿到appid

b. 配置应用

添加支付功能,签约,

生成密钥，上传公钥，生成密钥地址：[https://docs.open.alipay.com/291/105971][https_docs.open.alipay.com_291_105971]

c.集成和开发

d.调用接口

### 3. 服务端需要开发的接口 ###

a. 下单接口，返回带签名的订单信息给前端

b. 异步回调接口 参考同步和异步通知 地址：[https://docs.open.alipay.com/204/105301/][https_docs.open.alipay.com_204_105301]

### 4. 实例 ###

# 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。

# PHP服务端验证异步通知信息参数示例 #

$aop = new AopClient;
    $aop->alipayrsaPublicKey = '请填写支付宝公钥，一行字符串';
    $flag = $aop->rsaCheckV1($_POST, NULL, "RSA2");
