一、服务层

二、控制层

1.控制层

2.接口返回参数实例

前言

单笔转账接口 ｜ 网页&移动应用

准备：

应用的证书（证书申请和配置可以参考我另一篇分享“支付宝 ‘应用证书配置’ ”）

配置证书后注意公共参数中 私钥值 是csr生成后的私钥

需要接口能力已开通

一、服务层

二、控制层

1.控制层

        public function getAccessToken($authCode,$nMoney)    {        $cAlipayMethod = new AlipayMethod();        // 换取授权访问令牌（获取返回中code对应的user_id）        $result        = $cAlipayMethod->getAccessToken($authCode);        if (!isset($result["alipay_system_oauth_token_response"])) {            // 换取授权访问令牌失败            return json(["code" => 0, "data" => $result]);        } else {            // 获取用户唯一标识            $alipayUserId = $result["alipay_system_oauth_token_response"]["user_id"];            // 请求转账            $result       = $cAlipayMethod->onPaymentByAlipay($alipayUserId, $nMoney);         if ($result["alipay_fund_trans_uni_transfer_response"]["code"] == "10000") {                dump("转账成功")                // 业务逻辑            } else {                dump("转账失败")                // 业务逻辑            }        }    }

2.接口返回参数实例

alipay.system.oauth.token(换取授权访问令牌)：成功：{   "alipay_system_oauth_token_response": {      "access_token": "....",      "alipay_user_id": "....",      "auth_start": "2022-11-19 11:05:18",      "expires_in": ....,      "re_expires_in": ....,      "refresh_token": "....",      "user_id": "...."                       // 用户标识：是我们需要的   },   "alipay_cert_sn": "....",   "sign": "...."}错误：{   "error_response": {      "code": "40002",      "msg": "Invalid Arguments",      "sub_code": "isv.code-invalid",      "sub_msg": "授权码code无效"   },   "alipay_cert_sn": "....",   "sign": "...."}alipay.fund.trans.uni.transfer(单笔转账接口)转账到支付宝账号:成功：{   "alipay_fund_trans_uni_transfer_response": {      "code": "10000",      "msg": "Success",      "order_id": "....",      "out_biz_no": "....",      "pay_fund_order_id": "....",      "status": "SUCCESS",      "trans_date": "2022-11-18 13:45:02"   },   "alipay_cert_sn": "....",   "sign": "...."}异常：{   "alipay_fund_trans_uni_transfer_response": {      "code": "40004",      "msg": "Business Failed",      "sub_code": "INVALID_PARAMETER",      "sub_msg": "参数有误参数payee_info.identity格式非法"   },   "alipay_cert_sn": "....",   "sign": "...."}
