uniapp端，前端代码

// 在需要的地方引入
//#ifdef APP-PLUS
AliPayApp(this);
//#endif


// 支付宝app支付
function AliPayApp(that) {
	console.log('AliPayApp')
	// 1、获取支付宝订单信息
	that.$http.httpGet('/app.php',{
		courseid: that.courseId,
		type: 'AliPayApp',
	}).then((res) => {
		// console.log(res.data);
		uni.requestPayment({
		    provider: 'alipay',
		    orderInfo: res.data,
		    success: function(res) {
		        // console.log('success:' + JSON.stringify(res));
			that.$utils.msg('支付成功');
			that.$utils.redirectTo('my/myorder');
		    },
		    fail: function(err) {
		        // console.log('fail:' + JSON.stringify(err));
			that.$utils.msg(err.errMsg)
		    }
		});
	}).catch((error) => {
		console.log(error);
	});
}

app.php端代码

// 1、引入支付宝sdk

require  '../alipay/AopClient.php';
require  '../alipay/request/AlipayTradeAppPayRequest.php';

// 2、支付宝订单信息

$alipay_order_info = AliPayApp($oid,$price);
exit(json_encode(array('code' => 0,"msg" => "获取成功!","data" => $alipay_order_info))); }

3、AliPayApp函数

function AliPayApp($oid,$price){
	$aop = new AopClient;
	$aop->gatewayUrl = "https://openapi.alipay.com/gateway.do";
	$aop->appId = "";
	$aop->rsaPrivateKey = '';
	$aop->format = "json";
	$aop->charset = "UTF-8";
	$aop->signType = "RSA2";
	$aop->alipayrsaPublicKey = '';
	$request = new AlipayTradeAppPayRequest();
	$bizcontent = "{/"body/":/"ZZZ/"," 
	                . "/"subject/": /"ZZZ/","
	                . "/"out_trade_no/": /"".$oid."/","
	                . "/"timeout_express/": /"30m/"," 
	                . "/"total_amount/": /"".$price."/","
	                . "/"product_code/":/"QUICK_MSECURITY_PAY/""
	                . "}";
	$request->setNotifyUrl("http://www.boruiweb.com/api/v1/app_alipay_notify.php");
	$request->setBizContent($bizcontent);
	$res = $aop->sdkExecute($request);
	return $res;
}
