tp5.1 樂百分支付(分期)

注意：樂百分是分測試與正式帳號的

3，注意事項：
1.交易金額範圍（600—50000）元。

2.交易測試賬號：接口使用（商戶名稱、商戶編號、接口密碼）樂百分管理後臺使用（商戶登錄賬號、登錄密碼、退款密碼、PC端登陸地址）。

3.測試環境只能使用測試卡信息表中的卡號、cvn、有效期等信息做測試交易，身份證號可以填寫真實個人身份證，若填寫真實的卡號等信息是無法做交易的。

4.測試時需要接收短信驗證碼，因此手機號要爲真實有效的手機號碼。若無法接收短信，切勿多次觸發短信驗證碼，可檢查是否手機網絡問題，或同一手機號測試交易過多，換其他手機號測試。

5.爲了測試方便測試環境的扣款間隔爲兩天一期，若需測試退款請在交易第二天（清算後）操作。

6.測試完成，要接到樂百分生產環境時需更換商戶編號、商戶名稱、商戶簡稱、接口密碼、生產環境域名，證書不用更換。

1.PC控制器方法

	        $params = [
	            'choose_installments_num' => $choose_installments_num,//分期數
	            'body' => $body,//訂單名稱 商品簡單描述
	            'out_trade_no' => $out_trade_no,//訂單號
	            'total_fee' => $price,//總價格 如果購買多個商品，就是多個商品的總價 ,
	        ];
	    	$returnDa = new \lfqpay\LebaifenPay;
	    	$result=$returnDa->buildRequestForm($params);

2.移動方法（API接口方式）

參數組成一個網址形式返回給前端網頁，收到網址就是打開一個外部連接網址

https://tt.lfqpay.com/lfq-pay/gateway/api/frontTransRequest.do?certId=&version=&txnType=&frontUrl=&backUrl=&encoding=&merId=&merName=&merAbbr=&orderId=&txnTime=&txnAmt=&txnTerms=txnTermsList&merNote=&userMac=&validTime=&signature=

			        $params = [
			            'choose_installments_num' => $choose_installments_num,//分期數
			            'body' => $body,//訂單名稱 商品簡單描述
			            'out_trade_no' => $out_trade_no,//訂單號
			            'total_fee' => $price,//總價格 如果購買多個商品，就是多個商品的總價 ,
			        ];
			    	$returnDa = new \lfqpay\LebaifenPay;
			    	$result=$returnDa->buildRequestFormApp($params);
			    	if(empty($result)){
			    		throw new \Exception(json_encode(array('code'=>7001,'msg'=>'缺少必要參數','out_trade_no'=>$out_trade_no)));
			    	}
			    	$returnArr['url']=$result['url'].$result['certId'].$result['version'].$result['txnType'].$result['frontUrl'].$result['backUrl'].$result['encoding'].$result['merId'].$result['merName'].$result['merAbbr'].$result['merPwd'].$result['orderId'].$result['txnTime'].$result['txnAmt'].$result['txnTerms'].$result['txnTermsList'].$result['merNote'].$result['userMac'].$result['validTime'].$result['signature'];

重點：簽名那裏要urlencode($sign)，不然網址帶+空變是空格的，會驗證失敗

 

3.回調

   //同步調回接口  樂百分分期 支付
    public function lfqpay_notify_url(){
    	$postStr=input('get.');
    	
    	if($postStr['respCode']=='0000'){//成功
    		$this->lfqpayNotify($postStr);
    	}else{
    		
            if($postStr['respCode']=='0140'){//單筆交易金額不在規定範圍內
            	$msg=',金額在600-50000元之間';
            }
            $respMsg=$postStr['respMsg'].$msg;
            
    		$this->error($respMsg,'index/user/order');
    	}
    	
    }
    
    //異步調回接口 樂百分分期 支付
    public function lfqpay_notify(){
		
		$data=input('post.');
		$orderId=input('post.orderId');
		$respMsg=input('post.respMsg');
		$respCode=input('post.respCode');

		//收到支付成功通知變更訂單狀態
		if($orderId&&$respMsg=='成功'&&$respCode=='0000'){
		 	//收到支付成功通知變更訂單狀態
			$this->lfqpayNotify($data);
			//處理完所有訂單狀態等信息後輸出success
			echo "success";
		}
		
    }
    
    //樂百分分期支付成功後回調共同的操作
    public function lfqpayNotify($data){
			//判斷合法性 
	    	$returnDa = new \lfqpay\LebaifenPay;
	    	$sign_is=$returnDa->_vertify_sign($data);
	    	if(!empty($sign_is)){
                //成功
	    	}
		    
    }
