支付宝证书模式PHP类库

PHP版本 >= 8.0

支持APP支付、电脑网页、手机网页支付、单笔转账到支付宝、单笔转账到银行卡、当面付（扫码模式）、当面付（付款码模式）、异步通知验签、支持链式调用。

调用示例：

一、电脑网页支付：

<?php
    
    require_once "EasyAliPay.php";
	
	try {
        $pay = new EasyAliPay();
        $pay->setAppId("应用APPID");    //请确保在该APPID下已开通了电脑网页支付
        $pay->setPrivate_key("应用私钥");
        //$pay->setPrivateKeyPath("私钥路径")   //与setPrivateKey二选一即可
        $pay->setBizContent([
            "total_amount" => 300,
            "out_trade_no" => "你的订单号",
            "subject" => "会员充值",
        ]);
        $pay->setReturnUrl("支付完返回地址");
        $pay->setNotifyUrl("异步通知地址");
        $pay->setRootSecretPath("./root_key.crt");  //设置支付宝根证书路径
        $pay->setAppSecretPath("./app_key.crt");	//设置应用证书路径
        $result =  $pay->doPaymentRequest();
        echo $result;
    }catch (ErrorException $e) {
        echo $e->getMessage();
    }

或：

<?php
    
    require_once "EasyAliPay.php";
	
	try {
        $pay = new EasyAliPay();
        $result = $pay->setAppId("应用APPID")
            ->setPrivate_key("应用私钥")
            ->setBizContent([
                "total_amount" => 300,
                "out_trade_no" => "你的订单号",
                "subject" => "会员充值",
            ])
            ->setReturnUrl("支付完返回地址")
            ->setNotifyUrl("异步通知地址")
            ->setRootSecretPath("./root_key.crt")
            ->setAppSecretPath("./app_key.crt")
            ->doPaymentRequest();
        echo $result;
    }catch (ErrorException $e) {
        echo $e->getMessage();
    }

二、手机网页支付

<?php
    
    require_once "EasyAliPay.php";
	
	try {

        $pay->setPrivate_key("应用私钥");
        //$pay->setPrivateKeyPath("私钥路径")   //与setPrivateKey二选一即可
        $pay->setBizContent([
            "total_amount" => 300,
            "out_trade_no" => "你的订单号",
            "subject" => "会员充值",
        ]);
        $pay->setReturnUrl("支付完返回地址");
        $pay->setNotifyUrl("异步通知地址");
        $pay->setRootSecretPath("./root_key.crt");  //设置支付宝根证书路径
        $pay->setAppSecretPath("./app_key.crt");	//设置应用证书路径
        $pay->setType("wap");
        $result =  $pay->doPaymentRequest();
        echo $result;
    }catch (ErrorException $e) {
        echo $e->getMessage();
    }
