快递100接口的调用过程

前言

    大部分的商城都需要调用快递的接口来记录商城的物流信息，这里就给出一种快递接口（快递100）调用的方法。

一、官方文档

二、具体实现

1. 商城服务与快递接口服务具体交互示意图：

    具体的实现逻辑为：

    我们将订单号发给快递100，然后订阅该订单号的消息。当快递100中有订阅信息产生的时候，就会给指定的地址发一个消息去推送类似的消息。

　　贵公司将需要跟踪的运单提交给快递100指定的接口，快递100接到后就对这些单号进行监控，如果监控到运单有了更新，就主动将这些物流跟踪信息推送到贵公司指定的接口，
直到这些单的生命周期结束（一般以“已签收”为准），一个运单快递100一般会多次推送多条跟踪信息，贵方将之保存到数据库。当用户登录贵方网站、系统或手机APP时，
直接从贵司的数据库读取数据，并显示于贵方的网站、系统或手机APP。

2. 代码实现

（1）订阅某个订单信息

    public static function subscribeExpress($courier_company, $courier_no)
    {
        $data = [
            'company' => $courier_company,
            'number' => $courier_no,
            'key' => config('express_config.poll_key'),
            'parameters' => [
                'callbackurl' => env('API_HOST', 'http://panda.qujie8.com/') . 'api/alipay/express/notify',
                'departureCountry' => 'CN'
            ]
        ];
        $post_data = [
            'schema' => 'json',
            'param' => json_encode($data),
        ];
        Log::info('订阅快递100参数', [$post_data]);
        $o = '';
        foreach ($post_data as $k => $v) {
            $o .= "$k=" . urlencode($v) . '&';//默认UTF-8编码格式
        }

        $post_data = substr($o, 0, -1);
        $url = env('EXPRESS_PUST_URL', 'http://poll.kuaidi100.com/poll');

        $ch = curl_init();
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_HEADER, 0);
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
        $rst = curl_exec($ch);
        curl_close($ch);

        Log::info('订阅快递100结果', [$rst]);
        $rst = json_decode($rst, 1);
        Log::info('订阅快递100结果', [$rst]);

        if ($rst['result'] == false) {
            if ($rst['returnCode'] == 501) {
                Log::info('订阅快递100重复', [$rst, 'company' => $courier_company, 'courier_no' => $courier_no]);
                return true;
            }
            throw new ServiceException('订阅快递100失败', $rst['returnCode']);
        }
        return true;
    }

（2）接收每个订单信息的回调

    /**
    * 快递100回调
    */
    public static function notifyExpressInfo($poll_express_info)
    {
        $company = array_get($poll_express_info['lastResult'], 'com');
        $number = array_get($poll_express_info['lastResult'], 'nu');

        $borrow_express_type = FrontConst::BORROW_EXPRESS_TYPE_BORROW;
        $borrow_info = Borrow::where('business_courier_company_name', $company)->where('business_courier_no', $number)->first();
        if (empty($borrow_info)) {
            $borrow_express_type = FrontConst::BORROW_EXPRESS_TYPE_RETURN;
            $borrow_info = Borrow::where('courier_company_name', $company)->where('courier_no', $number)->first();
        }
        if (!empty($borrow_info)) {
            if ($borrow_info->status == FrontConst::STATUS_BORROW_DONE_RETURN) {
                Log::info('---快递100传输已完成的订单号--', ['borrow_id' => $borrow_info->id, 'status' => $borrow_info->status, 'business_courier_no' => $borrow_info->business_courier_no, 'Request_courier_no' => $number]);
                throw new ServiceException('此单号已还书完成无需操作', -2000);
            }
        }
        if (empty($borrow_info)) {
            throw new ServiceException('没有该订单匹配的物流单号', -1000);
        }
        $express_last_info = array_get($poll_express_info, 'lastResult');
        if (empty($express_last_info)) {
            throw new ServiceException('没有最新快递物流信息', -1000);
        }
        $ischeck = array_get($express_last_info, 'ischeck');

        try {
            DB::beginTransaction();
            $express_data = array_reverse($express_last_info['data']);
            foreach ($express_data as $key => $value) {
                //查询该快递信息是否已经录入
                $borrow_express = BorrowExpress::where('borrow_id', $borrow_info->id)->where('ftime', $value['ftime'])->first();
                if (empty($borrow_express)) {
                    $express_info = [
                        'ischeck' => $ischeck,
                        'state' => ExpressConst::$expressState[$express_last_info['state']],
                        'ftime' => $value['ftime'],
                        'content' => $value['context'],
                        'control_status' => ExpressConst::$expressStatus[$poll_express_info['status']],
                        'control_message' => $poll_express_info['message'],
                    ];
                    //增加快递信息
                    self::addExpress($borrow_info->id, $borrow_info->borrow_source, $borrow_info->status, $express_info, $borrow_express_type);
                }
            }

            //快递被签收
            if ($ischeck == 1 && $borrow_express_type == FrontConst::BORROW_EXPRESS_TYPE_BORROW) {
                $borrow_info->status = FrontConst::STATUS_BORROW_RECEIPT_DELIVERY;

                    $borrow_info->dead_line = empty($dead_line_info['dead_line']) ? $borrow_info->dead_line : $dead_line_info['dead_line'];
                }
                $borrow_info->save();

                }
                if ($borrow_info->borrow_source == FrontConst::SOURCE_ALIPAY) {
                    //判断是否是信用借还
                    $notify_alipay_status = true;

                    //通知支付宝修改订单时间
                    if ($notify_alipay_status) {
                        BorrowRepository::orderRentModify($borrow_info, $dead_line_info['dead_line']);
                        Log::info('该订单' . $borrow_info->id . '使用的是' . $package_info->name . ',不需要修改到期时间', ['id' => $borrow_info->id]);
                    }
