tp5框架中調用支付寶線上資金預授權接口

下載支付寶sdk後解壓放到extend目錄下
在public/index.php中定義常量
參考文檔

define('ALI_PATH',__DIR__.'/../extend/alipay/aop/');

創建控制器並寫入代碼

require ALI_PATH.'AopClient.php';
require ALI_PATH.'request/AlipayFundAuthOrderAppFreezeRequest.php';

class Ali extends Controller{
	public static $appid = ''; //appid
    public static $pub_key = ''; //應用公鑰
    public static $prikey = ''; //應用私鑰
    public static $alipubkey = '';//支付寶公鑰

	public function shouquan()
    {
        $aop = new \AopClient ();
        $aop->gatewayUrl = 'https://openapi.alipay.com/gateway.do';
        $aop->appId = self::$appid;
        $aop->rsaPrivateKey = self::$prikey;
        $aop->alipayrsaPublicKey=self::$alipubkey;
        $aop->apiVersion = '1.0';
        $aop->signType = 'RSA2';
        $aop->postCharset='UTF-8';
        $aop->format='json';
        $request = new \AlipayFundAuthOrderAppFreezeRequest ();
        $order_no = time().rand(1111,9999).'orderid';
        $l = time().rand(1111111,9999999).'liushui';
        DB::name('ali_demo')->insert(['order_no'=>$order_no,'l'=>$l]); //將生成的訂單號和流水號存儲在數據庫，查訂單，撤銷訂單時需要用到
        $request->setBizContent("{" .
        "\"out_order_no\":\"".$order_no."\"," . //商戶訂單號
        "\"out_request_no\":\"".$l."\"," .       //商戶流水號
        "\"order_title\":\"測試預授權凍結\"," .    //描述
        "\"amount\":0.01," .                      //金額
        "\"product_code\":\"PRE_AUTH_ONLINE\"," .
        "\"payee_logon_id\":\"[email protected]\"," . //收款方支付寶賬號
        "\"pay_timeout\":\"90m\"," .
        "\"scene_code\":\"ONLINE_AUTH_COMMON_SCENE\"," .
        "\"trans_currency\":\"CNY\",".
        "\"settle_currency\":\"CNY\",".
        "\"enable_pay_channels\":\"[{\\\"payChannelType\\\":\\\"PCREDIT_PAY\\\"},{\\\"payChannelType\\\":\\\"MONEY_FUND\\\"}]\"" .
        "  }");
        $request->setNotifyUrl(''); //請求成功後的回調地址
        $result = $aop->sdkexecute ( $request);
        return json_encode($result);
    }
}

上面的方法返回一個字符串，將字符串傳到前端，前端用這個字符串來喚起支付頁面，在支付寶app執行資金凍結
返回的字符串中有資金授權查詢接口需要的請求參數數據
