支付寶證書簽名 PHP SDK

PHP 接入支付寶證書方式簽名以及驗簽

支付寶在 2019.10.25 日左右更新了新的 PHP SDK （v4.1.0）。 之前的 PHP SDK（v3.4.2） 僅支持公鑰方式加簽。這次更新之后 PHP SDK 也可以使用證書進行簽名和驗簽了。

支付寶官方 SDK 下載地址

下載解壓 並將文件夾中的 aop 文件夾 直接復制到項目中你想要放到文件夾里，例如 extend
文件夾 （為了測試 crt 證書文件也已經放到同目錄下 cert 目錄中了）

先修正 SDK 中的1個小錯誤：AopCertClient.php 中
478 行左右 有一個檢查是否為空的方法

修改為

	if (method_exists($request, 'getApiVersion')){
        $iv = $request->getApiVersion();
    }else{
        $iv = $this->apiVersion;
    }

   
   
  
  
          

引入文件

	require_once EXTEND_PATH.'aop/AopCertClient.php';
	require_once EXTEND_PATH.'aop/AopCertification.php';
	require_once EXTEND_PATH.'aop/request/AlipayTradeQueryRequest.php';
	require_once EXTEND_PATH.'aop/request/AlipayTradeWapPayRequest.php';
	require_once EXTEND_PATH.'aop/request/AlipayOpenOperationOpenbizmockBizQueryRequest.php';

   
   
  
  
          

從 aop/test/ 目錄下 找下 AopCertClientTest.php （因為是使用證書進行簽名，如果是使用公鑰進行簽名，就應該參考 AopClientTest.php 文件，不做贅述）直接復制相關代碼進行修改比如 我復制的就是

	//1、execute 使用
	$aop = new AopCertClient ();
	$appCertPath = "應用證書路徑（要確保證書文件可讀），例如：/home/admin/cert/appCertPublicKey.crt";
	$alipayCertPath = "支付寶公鑰證書路徑（要確保證書文件可讀），例如：/home/admin/cert/alipayCertPublicKey_RSA2.crt";
	$rootCertPath = "支付寶根證書路徑（要確保證書文件可讀），例如：/home/admin/cert/alipayRootCert.crt";

因為我要用的是 單筆轉賬到支付寶賬戶的接口。
所以 上面的代碼要修改兩個地方。

	$request = new AlipayFundTransToaccountTransferRequest ();
	// 官方示例 切記要自己修改
	$request->setBizContent("{" .
	"\"out_biz_no\":\"3142321423432\"," .
	"\"payee_type\":\"ALIPAY_LOGONID\"," .
	"\"payee_account\":\"[e-mail]\"," .
	"\"amount\":\"12.23\"," .
	"\"payer_show_name\":\"上海交通卡退款\"," .
	"\"payee_real_name\":\"張三\"," .
	"\"remark\":\"轉賬備注\"" .
	" }");

   
   
  
  
          

修改完成之后，就可以跑代碼進行測試了。
