$response = $app->getClient()->postJson('v3/pay/transactions/native', [
    'mchid' => (string)$app->getMerchant()->getMerchantId(),
    'out_trade_no' => 'native20210720xxx',
    'appid' => 'wxe2fb06xxxxxxxxxx6',

print_r($response->toArray(false));

$outTradeNo = 'native20210720xxx';
$response = $app->getClient()->get("v3/pay/transactions/out-trade-no/{$outTradeNo}", [

        'mchid' =>  $app->getMerchant()->getMerchantId()
    ]
]);

print_r($response->toArray());

Laravel 中处理微信支付回调

记得需要将此类路由关闭 csrf 验证。

// 假设你设置的通知地址notify_url为: https://easywechat.com/payment_notify

// 注意:通知地址notify_url必须为https协议

Route::post('payment_notify', function () {
    // $app 为你实例化的支付对象,此处省略实例化步骤
    $server = $app->getServer();

    // 处理支付结果事件
    $server->handlePaid(function ($message) {
        // $message 为微信推送的通知结果,详看微信官方文档

        // 微信支付订单号 $message['transaction_id']
        // 商户订单号 $message['out_trade_no']
        // 商户号 $message['mchid']
        // 具体看微信官方文档...
        // 进行业务处理,如存数据库等...
    });

    // 处理退款结果事件
    $server->handleRefunded(function ($message) {
        // 同上,$message 详看微信官方文档
        // 进行业务处理,如存数据库等...
    });

    return $server->serve();
});
付款(V2)
$response = $api->post('/mmpaymkttransfers/promotion/transfers', [
    'body' => [
        'mch_appid' => $app->getConfig()['app_id'],     //注意在配置文件中加上app_id
        'mchid' => $app->getConfig()['mch_id'],         //商户号
        'partner_trade_no' => '202203081646729819743',  // 商户订单号,需保持唯一性(只能是字母或者数字,不能包含有符号)
        'openid' => 'ogn1H45HCRxVRiEMLbLLuABbxxxx',     //用户openid
        'check_name' => 'FORCE_CHECK',                  // NO_CHECK:不校验真实姓名, FORCE_CHECK:强校验真实姓名
        're_user_name'=> '用户真实姓名',                  // 如果 check_name 设置为 FORCE_CHECK 则必填用户真实姓名
        'amount' => '100',                              //金额
        'desc' => '理赔',                                // 企业付款操作说明信息。必填
    ],
    'local_cert' => $app->getConfig()['certificate'], //v2证书绝对路径
    'local_pk' => $app->getConfig()['private_key'],   //v2证书密钥绝对路径
]);

print_r($response->toArray());
