[PHP知识库]PHP对接苹果支付全流程

对接苹果支付流程上相较于微信或者支付宝来说后端做的代码是非常少的但是需要注意的点很多

对于支付最重要的是知道这笔支付到底是不是真正意义上成交了，以及成交价格是否对应我们的商品价格这是我们需要去判断的

苹果支付对于微信支付和支付宝支付来说，有本质的区别。苹果支付的商品需要现在appstore里面去上架。所以整个支付流程如下

APP内请求苹果SDK发起支付。并完成购买。支付成功之后APP端会传一段receipt_data(同时需要带上APP支付成功的交易单号)给后端去做验证。后端拿到这个数据之后，会再次请求苹果服务器去解析数据。

结构如下:

        "receipt_type": "ProductionSandbox",
        "adam_id": 0,
        "app_item_id": 0,

            },
        ]
    },
    "environment": "Sandbox",
    "status": 0
}

订单总共如下几种状态

状态	描述
Purchased	购买成功
Restored	恢复购买
Failed	失败
Deferred	等待确认，儿童模式需要询问家长同意

app从服务器获取产品标识列表
app从app store 获取产品信息
用户选择需要购买的产品
app 发送支付请求到app store
app store 处理支付请求，返回transaction信息
app 将transaction receipt 发送到服务器
服务器收到收据后发送到app stroe验证收据的有效性
app store 返回收据的验证结果
根据app store 返回的结果决定用户是否购买成功

基本的支付校验流程如下：
在这里插入图片描述
下面贴上具体的业务逻辑代码

 public function actionsApplepay($receipt_data, $order_number, $transaction_id, $order_info, $is_test){
        $ret = array();
        $ret['status'] = 200;
        $ret['msg'] = "ok";

                    '21006' => 'receipt合法，但是订阅已过期。服务器接收到这个状态码时，receipt数据仍然会解码并一起发送',
