omnipay支付--支付宝支付

　　最近负责的项目事关支付宝APP支付也踩了一些坑这边记录下

以下代码基于laravel框架下:

生成APP支付参数:

　　　　$gateway = $this->getGateway();$request = $gateway->purchase();$request->setBizContent(['subject'      => '',//产品描述'out_trade_no' => '',//本地订单号'total_amount' => '',//支付金额 这里无需处理分位问题'product_code' => 'QUICK_MSECURITY_PAY',//销售产品码，商家和支付宝签约的产品码，为固定值
        ]);//发送请求$response = $request->send();//获取支付路径$orderString = $response->getOrderString();/**这里获取的参数 传给app前端由它去调用支付*/

回调处理:

官方文档是这样写的:

$request = $gateway->completePurchase();
$request->setParams($request);/*** @var LegacyCompletePurchaseResponse $response*/
try {$response = $request->send();if($response->isPaid()){/*** Payment is successful*/die('success'); //The response should be 'success' only}else{/*** Payment is not successful*/die('fail');}
} catch (Exception $e) {/*** Payment is not successful*/die('fail');
}

然而我这样写后一直导致回调过来无法执行相应代码看了下日志一直报函数错误说setParams参数有问题无奈到处百度最后是在composer包里查看测试示例查看到这样写法:

$response = $gateway->completePurchase(['params' => $request])->send();

这样改正以后再不会报语法问题了回调也成功同步了

顺带说一下,这里的isPaid方法里面的代码是这样的:

if (array_get($this->data, 'trade_status')) {if (array_get($this->data, 'trade_status') == 'TRADE_SUCCESS') {return true;} elseif (array_get($this->data, 'trade_status') == 'TRADE_FINISHED') {return true;} else {return false;}} elseif (array_get($this->data, 'code') == '10000') {return true;} else {return false;}

说明它已经验证了支付状态所以可以以此判断是否支付成功.

查询:

$options = ['out_trade_no' => $data['order_no']];//用本地订单号查询$options = ['trade_no' => $data['trade_no']];//支付宝订单号查询//查询订单
$request = $gateway->query();$request->setBizContent($options);$response = $request->send();//查询成功获取返回信息数据if($response->isSuccessful()) {return $response->getAlipayResponse();} else {return FALSE;}
