支付宝支付 公钥证书方式

对接支付宝【单笔转账接口】时发现资金支出类接口只能使用证书方式,遂引入最新sdk,修改原支付接口,并增加转账接口

AlipayBase.php

appId = 'test1111111111';//TODO 支付宝应用id

        $this->rsaPrivateKeyPath = root_path() . "library/alipay/rsaPrivateKey.txt";//TODO 使用支付宝开放平台开发助手生成的应用私钥
        $this->appCertPath = root_path() . "library/alipay/appCertPublicKey_2021001154615307.crt";//TODO 上传证书后生成的crt文件 证书
        $this->rootCertPath = root_path() . "library/alipay/alipayRootCert.crt";//TODO 上传证书后生成的crt文件 支付宝根证书
        $this->alipayrsaPublicKeyPath = root_path() . "library/alipay/alipayCertPublicKey_RSA2.txt";//TODO 上传证书后生成的txt文件 支付宝公钥证书(不能使用支付宝开放平台开发助手生成的应用公钥,这样子会导致支付回调验签失败)

        $this->alipayrsaPublicKey = file_get_contents($this->alipayrsaPublicKeyPath);//TODO 代码示例中是这样获取的($aop->getPublicKey($alipayCertPath);//调用getPublicKey从支付宝公钥证书中提取公钥),获取不到,所以改成了file_get_contents
        $this->rsaPrivateKey = file_get_contents($this->rsaPrivateKeyPath);
