tp5框架中調用支付寶線上資金預授權alipay.fund.auth.order.app.freeze接口

官方文檔
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\"," .  //銷售產品碼 固定值PRE_AUTH_ONLINE
        "\"payee_logon_id\":\"[email protected]\"," . //收款方支付寶賬號 郵箱或手機號
        "\"payee_user_id\":2088***********," . //支付寶用戶id 與上方參數任選其一
        "\"pay_timeout\":\"90m\"," . //最晚付款時間 90m表示90分鐘後      
        "\"scene_code\":\"ONLINE_AUTH_COMMON_SCENE\"," . //業務場景
        "\"trans_currency\":\"CNY\",". //標價幣種 CNY表示人民幣
        "\"settle_currency\":\"CNY\",". //結算幣種
        "\"enable_pay_channels\":\"[{\\\"payChannelType\\\":\\\"PCREDIT_PAY\\\"},{\\\"payChannelType\\\":\\\"MONEY_FUND\\\"}]\"" . //指定支付渠道 花唄 餘額寶
        "  }");
        $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
小程序前端官方文檔
小程序代碼

aliget() {
    my.request({
      url: '', //請求資金預授權接口 返回一個長字符串
      data:{id:9},
      method: 'GET',
      success: function (res) {   
          my.tradePay({
            // 調用資金凍結接口（alipay.fund.auth.order.app.freeze），獲取資金授權參數
            orderStr: res.data,
            success: (res) => {
              my.request({
                url: '', //我是在這裏做的回調 官方的回調不知道爲什麼一直沒有執行
                data:{data:res.result}, //將支付寶返回的數據傳到後臺
                type:"post",
                success:function(res){
					//授權成功
                }
              })
              console.log(res); 
            },
            fail: (res) => {
              my.alert({
                content: JSON.stringify(res),
              });
            } 
          })
      },
      // 調用失敗的回調函數 
      fail: function (res) {
        my.alert({ content: 'fail' });
      }, 
    });
  },

在回調中保存支付寶授權號，流水號等，別的接口能用到
後臺回調代碼

public function ordercreate()
    {
        $res = json_decode(input('data'));
        $order = AliOrder::where('order_no',$res->alipay_fund_auth_order_app_freeze_response->out_order_no)->find();
        $order->auth_no = $res->alipay_fund_auth_order_app_freeze_response->auth_no;
        $order->user_id = $res->alipay_fund_auth_order_app_freeze_response->payer_user_id;
        $order->ali_liushui = $res->alipay_fund_auth_order_app_freeze_response->operation_id;
        $order->status = 1;
        $order->save();
    }
