Wechatpay 微信支付

配置

$config = array(
    'appid' => '',			//填写高级调用功能的app id
    'appsecret' => '', 		//填写高级调用功能的app secret
    'mchid' => '',			//商户id
    'key' => '', 			//填写你设定的key
    'sslcert_path' => '/your/path/cert/wechatpay/apiclient_cert.pem'
    'sslkey_path' => '/your/path/cert/wechatpay/apiclient_key.pem',
    'transfer_rsa_public_path' => '/your/path/cert/wechatpay/rsa_public.pem',	//企业转账到银行卡rsa公钥证书文件路径
);

即时到账接口

  1. 判断设备选择实例化的

公众号

$wechatpay = new \JiaLeo\Payment\Wechatpay\MpPay($config);

App

$wechatpay = new \JiaLeo\Payment\ Wechatpay\AppPay($config);

H5

$wechatpay = new \JiaLeo\Payment\ Wechatpay\H5Pay($config);

Native

$wechatpay = new \JiaLeo\Payment\ Wechatpay\NativePay($config);

示例代码：

if ($data['device'] == 'mp') {
	$wechatpay = new \JiaLeo\Payment\Wechatpay\MpPay($config);
} elseif ($data['device'] == 'app') {
	$wechatpay = new \JiaLeo\Payment\Wechatpay\AppPay($config);
}
elseif($data['device'] == 'h5'){
	$wechatpay = new \JiaLeo\Payment\Wechatpay\H5Pay($config);
}
elseif ($data['device'] == 'native') {
    $wechatpay = new \JiaLeo\Payment\Wechatpay\NativePay($config);
}

$out_trade_no = date('YmdHis') . rand(10000, 99999);

$pay_data = [
	'body' => $data['body'], //内容
	'attach' => $wechatpay->setPassbackParams($return_params), //商家数据包
	'out_trade_no' => $out_trade_no, //商户订单号
	'total_fee' => $data['amount'], //支付价格(单位:分)
	'openid' => $openid,
	'notify_url' => 'http://domain/api/wechatpay/notifies/' . $data['device'] //后台回调地址
];

$url = $wechatpay->handle($pay_data);

MpPay和AppPay返回的url为微信的签名，只要直接给到客户端给可以了。

H5Pay为微信返回的url，需要额外重定向和指定支付完成后的跳转地址：

NativePay返回的是一个微信支付url,使用第三方库直接转换成二维码即可

支付回调处理

示例代码：

$wechatpay = new \JiaLeo\Payment\Wechatpay\Notify($config);

try {
	//验签
	$data = $wechatpay->handle();

	$wechatpay->returnSuccess();
	$result = true;
} catch (\Exception $e) {
	$error_msg = $e->getMessage();
	$wechatpay->returnFailure($error_msg);
}

退款

示例代码：

$wechatpay_refund = new \JiaLeo\Payment\Wechatpay\Refund($config);
$out_refund_no = date('YmdHis').rand(10000, 99999);

try {
    //原路退款
    $refund_data = [
        'out_refund_no' => $out_refund_no,//退款商户单号
        'total_fee' => $amount, //原订单金额（单位分）
        'refund_fee' => $refund_amount, //退款金额（单位分）
        'out_trade_no' => $out_trade_no, //原订单商户单号
        'refund_account' => 'REFUND_SOURCE_UNSETTLED_FUNDS' //退款资金来源-未结算资金退款
        'notify_url' => 'http://domain/api/wechatpay/notifies/' . $data['device'] //后台回调地址
    ];

    try {
        $wechatpay_refund->handle($refund_data);
    } catch(\Exception $e) {
        $refund_data['refund_account']='REFUND_SOURCE_RECHARGE_FUNDS';  //退款资金来源-可用余额退款
        $wechatpay_refund->handle($refund_data);
    }
}

退款回调处理

示例代码：

$wechatpay = new \JiaLeo\Payment\Wechatpay\RefundNotify($config);

try {
	//验签
	$data = $wechatpay->handle();

	$wechatpay->returnSuccess();
	$result = true;
} catch (\Exception $e) {
	$error_msg = $e->getMessage();
	$wechatpay->returnFailure($error_msg);
}

企业付款

  • 企业付款到零钱

示例代码：

$config = config('payment.wechatpay.mp');
$payment = new \JiaLeo\Payment\Wechatpay\Transfer($config);
$params = array(
	'partner_trade_no' => time() . rand(10000, 99999), //转账订单号
	'openid' => 'oErxPsxn6XTQQyFzauQW9qZYtI_k', //openid
	'amount' => 100, //转账金额(单位:分)
	'desc' => '测试转账', //备注
	//'check_name' => true //是否验证实名
);
$res = $payment->handle($params);
if (!$res) {
	var_dump($payment->errorCode, $payment->errorCodeDes);
}
var_dump($res);

  • 企业付款到银行卡

    1. 调用获取RSA公钥API获取RSA公钥，落地成本地文件，假设为rsa_public.pem

      $config = config('payment.wechatpay.che');
$wechatpay = new \JiaLeo\Payment\Wechatpay\Tools($config);
$url = $wechatpay->getPublicKey();
var_dump($url['pub_key']);

    2. PKCS#1 转 PKCS#8 (微信获取的是PKCS#1的格式，php必须读取PKCS#8)

      openssl rsa -RSAPublicKey_in -in <filename> -pubout

      替换原证书内容

    3. 执行

      $config = config('payment.wechatpay.che');
$wechatpay = new \JiaLeo\Payment\Wechatpay\Transfer($config);

$data = array(
	'partner_trade_no' => time(),
	'amount' => 100,
	'bank_no' => '62148312XXXXXX',
	'true_name' => 'XXX',
	'bank_code' => '1001',
	'desc' => 'test',
);


var_dump($wechatpay->handleToBank($data));

红包

普通红包：

$config = config('payment.wechatpay.mp');
$payment = new \JiaLeo\Payment\Wechatpay\RedPack($config);

$params = array(
	'mch_billno' => time() . rand(10000, 99999),
	'send_name' => '汉子科技',
	'openid' => 'oErxPsxn6XTQQyFzauQW9qZYtI_k',
	'wishing' => '汉子科技恭喜发财',
	'act_name' => '汉子科技哈哈',
	'remark' => '备注',
	'total_amount' => 300
);
$res = $payment->sendRedPack($params);

if (!$res) {
	dump($payment->errorCode, $payment->errorCodeDes);
}

dump($res);

裂变红包：

$config = config('payment.wechatpay.mp');
$payment = new \JiaLeo\Payment\Wechatpay\RedPack($config);

$params = array(
	'mch_billno' => time() . rand(10000, 99999),
	'send_name' => '汉子科技',
	'openid' => 'oErxPsxn6XTQQyFzauQW9qZYtI_k',
	'wishing' => '汉子科技恭喜发财',
	'act_name' => '汉子科技哈哈',
	'remark' => '备注',
	'total_amount' => 300,
	'total_num' => 3
);
$res = $payment->sendGroupRedPack($params);

if (!$res) {
	dump($payment->errorCode, $payment->errorCodeDes);
}

dump($res);
