注意：乐百分是分测试与正式帐号的

3，注意事项：
1.交易金额范围（600—50000）元。

2.交易测试账号：接口使用（商户名称、商户编号、接口密码）乐百分管理后台使用（商户登录账号、登录密码、退款密码、PC端登陆地址）。

3.测试环境只能使用测试卡信息表中的卡号、cvn、有效期等信息做测试交易，身份证号可以填写真实个人身份证，若填写真实的卡号等信息是无法做交易的。

4.测试时需要接收短信验证码，因此手机号要为真实有效的手机号码。若无法接收短信，切勿多次触发短信验证码，可检查是否手机网络问题，或同一手机号测试交易过多，换其他手机号测试。

5.为了测试方便测试环境的扣款间隔为两天一期，若需测试退款请在交易第二天（清算后）操作。

6.测试完成，要接到乐百分生产环境时需更换商户编号、商户名称、商户简称、接口密码、生产环境域名，证书不用更换。

1.PC控制器方法

$params = [
'choose_installments_num' => $choose_installments_num,//分期数
'body' => $body,//订单名称 商品简单描述
'out_trade_no' => $out_trade_no,//订单号
'total_fee' => $price,//总价格 如果购买多个商品，就是多个商品的总价 ,
];
$returnDa = new \lfqpay\LebaifenPay;
$result=$returnDa->buildRequestForm($params);

2.移动方法（API接口方式）

参数组成一个网址形式返回给前端网页，收到网址就是打开一个外部连接网址

​​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,//分期数
'body' => $body,//订单名称 商品简单描述
'out_trade_no' => $out_trade_no,//订单号
'total_fee' => $price,//总价格 如果购买多个商品，就是多个商品的总价 ,
];
$returnDa = new \lfqpay\LebaifenPay;
$result=$returnDa->buildRequestFormApp($params);
if(empty($result)){
throw new \Exception(json_encode(array('code'=>7001,'msg'=>'缺少必要参数','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'];

重点：签名那里要urlencode($sign)，不然网址带+空变是空格的，会验证失败

3.回调

//同步调回接口 乐百分分期 支付
public function lfqpay_notify_url(){
$postStr=input('get.');

if($postStr['respCode']=='0000'){//成功
$this->lfqpayNotify($postStr);
}else{

if($postStr['respCode']=='0140'){//单笔交易金额不在规定范围内
$msg=',金额在600-50000元之间';
}
$respMsg=$postStr['respMsg'].$msg;

$this->error($respMsg,'index/user/order');
}

}

//异步调回接口 乐百分分期 支付
public function lfqpay_notify(){

$data=input('post.');
$orderId=input('post.orderId');
$respMsg=input('post.respMsg');
$respCode=input('post.respCode');

//收到支付成功通知变更订单状态
if($orderId&&$respMsg=='成功'&&$respCode=='0000'){
//收到支付成功通知变更订单状态
$this->lfqpayNotify($data);
//处理完所有订单状态等信息后输出success
echo "success";
}

}

//乐百分分期支付成功后回调共同的操作
public function lfqpayNotify($data){
//判断合法性
$returnDa = new \lfqpay\LebaifenPay;
$sign_is=$returnDa->_vertify_sign($data);
if(!empty($sign_is)){
//成功
}

}
