CodeIgniter 开发，支付宝接口调用实例

发布时间：2020-05-25 23:17:58 所属栏目：PHP 来源：互联网

导读：准备：1、alipay官方下载最新接口类库2、解压后，将目录即时到账交易接口-create_direct_pay_by_userdemocreate_direct_pay_by_user-PHP-UTF-8lib复制到 applicationthird_party目录下，并改名lib为alipay3、同样复制cacert.pem文件到applicationthird_partya

准备：
1、alipay官方下载最新接口类库
2、解压后，将目录"即时到账交易接口-create_direct_pay_by_userdemocreate_direct_pay_by_user-PHP-UTF-8lib"复制到 applicationthird_party目录下，并改名lib为alipay
3、同样复制cacert.pem文件到"applicationthird_partyalipay"目录下，这个不是必须的，在走ssl通道时用到的证书

代码实例:
以下只列出controller部分代码，view与model根据自己实际需要去编写
