【宋词】《贺新郎》 李玉：篆缕销金鼎。醉沈沈、庭阴转午，画堂人静。芳草王孙知何处，惟有杨花糁径。渐玉枕、腾腾春醒。帘外残红春已透，

微信第三方平台 component_verify_ticket 超时提醒的排查与解决

在告警群中未再接收到告警通知。其最后一条告警通知时间 2020-12-04 15:54:56。由此确定，覆盖现网全网发布与否才是告警的根本原因。

2、在通知群中频繁收到同一类超时提醒。整理时间后发现，提醒大致每 40 分钟出现一次，例如 11:25、12:15、12:55、13:35、14:15，如图2。

通知群中频繁出现同一类超时提醒，并呈现较固定的时间间隔。

3、首先参考微信开放平台关于 component_verify_ticket 的官方说明：https://developers.weixin.qq.com/doc/oplatform/Third-party_Platforms/api/component_verify_ticket.html 。

4、接着检查当前项目中接收 component_verify_ticket 的实现。

PHP
    /**
     * Component Verify Ticket 协议接收
     */
    public function actionTicket()
    {
        $bathPath = Yii::$app->getBasePath();
        try {
            $requestRowBody = Yii::$app->getRequest()->getRawBody();
            $requestQueryParams = Yii::$app->getRequest()->getQueryParams();
            @file_put_contents($bathPath . '/runtime/requestRowBody.txt', var_export($requestRowBody, true), LOCK_EX);
            @file_put_contents($bathPath . '/runtime/requestQueryParams.txt', var_export($requestQueryParams, true), LOCK_EX);


            $appId = Yii::$app->params['wxOpen']['component']['appId'];
            $appSecret = Yii::$app->params['wxOpen']['component']['appSecret'];
            $token = Yii::$app->params['wxOpen']['component']['token'];
            $encodingAesKey = Yii::$app->params['wxOpen']['component']['symmetricKey'];

            $msg = '';
            $pc = new WXBizMsgCrypt($token, $encodingAesKey, $appId);
            // 解密 xml 数据
            $errCode = $pc->decryptMsg($requestQueryParams['msg_signature'], $requestQueryParams['timestamp'], $requestQueryParams['nonce'], $requestRowBody, $msg);
            @file_put_contents($bathPath . '/runtime/decrypt_result.txt', $errCode, LOCK_EX);
            // 解密成功
            if ($errCode == 0) {
                $ticketData = $this->xmlToArray($msg);
                if (isset($ticketData['ComponentVerifyTicket'])) {
                    $redisCommandkeyPrefix = Yii::$app->params['redisCommand']['keyPrefix'];
                    $componentVerifyTicketKey = $redisCommandkeyPrefix . $ticketData['AppId'] . ':component_verify_ticket';
                    $this->redis->set($componentVerifyTicketKey, $ticketData['ComponentVerifyTicket']);
                    // 获取第三方平台component_access_token
                    $this->getComponentAccessToken($appId, $appSecret);
                }
            }
            @file_put_contents($bathPath . '/runtime/msgXml.txt', $msg, LOCK_EX);
        } catch (\Throwable $th) {
            @file_put_contents($bathPath . '/runtime/actionTicketError.txt', $th->getMessage(), LOCK_EX);
        }
        exit('success');
    }

5、先查看现有日志文件的创建时间，发现相关文件均在 14:35 左右生成，如图3。

查看现有日志文件的创建时间。

6、为了确认耗时位置，随后在多个关键环节记录服务器时间，对整个处理过程进行逐段排查。

PHP
    public function init()
    {
        file_put_contents(Yii::getAlias('@runtime') . '/wx-msg-event-ticket-' . Date('Y-m-d-H-i-s') . '-' . microtime(true) . '-' . mt_rand()  . '.txt', print_r('1', true), FILE_APPEND | LOCK_EX);
        parent::init();
        require __DIR__ . '/../vendor/wx_biz_msg_crypt/wxBizMsgCrypt.php';
        $this->redis = Yii::$app->redis;
        file_put_contents(Yii::getAlias('@runtime') . '/wx-msg-event-ticket-' . Date('Y-m-d-H-i-s') . '-' . microtime(true) . '-' . mt_rand()  . '.txt', print_r('1', true), FILE_APPEND | LOCK_EX);

    }

    /**
     * Component Verify Ticket 协议接收
     */
    public function actionTicket()
    {
        file_put_contents(Yii::getAlias('@runtime') . '/wx-msg-event-ticket-' . Date('Y-m-d-H-i-s') . '-' . microtime(true) . '-' . mt_rand()  . '.txt', print_r('1', true), FILE_APPEND | LOCK_EX);
        $bathPath = Yii::$app->getBasePath();
        try {
            $requestRowBody = Yii::$app->getRequest()->getRawBody();
            $requestQueryParams = Yii::$app->getRequest()->getQueryParams();
            @file_put_contents($bathPath . '/runtime/requestRowBody.txt', var_export($requestRowBody, true), LOCK_EX);
            @file_put_contents($bathPath . '/runtime/requestQueryParams.txt', var_export($requestQueryParams, true), LOCK_EX);


            $appId = Yii::$app->params['wxOpen']['component']['appId'];
            $appSecret = Yii::$app->params['wxOpen']['component']['appSecret'];
            $token = Yii::$app->params['wxOpen']['component']['token'];
            $encodingAesKey = Yii::$app->params['wxOpen']['component']['symmetricKey'];

            $msg = '';
            $pc = new WXBizMsgCrypt($token, $encodingAesKey, $appId);
            // 解密 xml 数据
            $errCode = $pc->decryptMsg($requestQueryParams['msg_signature'], $requestQueryParams['timestamp'], $requestQueryParams['nonce'], $requestRowBody, $msg);
            @file_put_contents($bathPath . '/runtime/decrypt_result.txt', $errCode, LOCK_EX);
            // 解密成功
            if ($errCode == 0) {
                $ticketData = $this->xmlToArray($msg);
                if (isset($ticketData['ComponentVerifyTicket'])) {
                    $redisCommandkeyPrefix = Yii::$app->params['redisCommand']['keyPrefix'];
                    $componentVerifyTicketKey = $redisCommandkeyPrefix . $ticketData['AppId'] . ':component_verify_ticket';
                    $this->redis->set($componentVerifyTicketKey, $ticketData['ComponentVerifyTicket']);
                    // 获取第三方平台component_access_token
                    $this->getComponentAccessToken($appId, $appSecret);
                }
            }
            @file_put_contents($bathPath . '/runtime/msgXml.txt', $msg, LOCK_EX);
        } catch (\Throwable $th) {
            @file_put_contents($bathPath . '/runtime/actionTicketError.txt', $th->getMessage(), LOCK_EX);
        }
        file_put_contents(Yii::getAlias('@runtime') . '/wx-msg-event-ticket-' . Date('Y-m-d-H-i-s') . '-' . microtime(true) . '-' . mt_rand()  . '.txt', print_r('1', true), FILE_APPEND | LOCK_EX);
        exit('success');
    }

7、2020-11-27 14:55:05 再次出现同类提醒。检查日志文件后发现，它们也都在 14:55:05 生成；两个时间戳相差约 3.25 毫秒。于是继续观察下一次出现时的日志时间，如图4。

11、结合现象，初步将排查重点放到第三方平台访问凭据的获取过程，并在该过程前后增加时间记录。

PHP
    file_put_contents(Yii::getAlias('@runtime') . '/wx-msg-event-ticket-' . Date('Y-m-d-H-i-s') . '-' . microtime(true) . '-' . mt_rand()  . '.txt', print_r('1', true), FILE_APPEND | LOCK_EX);
    // 获取第三方平台component_access_token
    $this->getComponentAccessToken($appId, $appSecret);
    file_put_contents(Yii::getAlias('@runtime') . '/wx-msg-event-ticket-' . Date('Y-m-d-H-i-s') . '-' . microtime(true) . '-' . mt_rand()  . '.txt', print_r('1', true), FILE_APPEND | LOCK_EX);

12、查看新增日志后，发现少量请求的耗时相对更长，相关时间差约为 25.26、41.48、44.26 和 39.62 毫秒，且大约每 2 小时出现一次，说明这一阶段存在周期性的耗时波动。

15、继续查看项目中的 HTTP 请求模型实现。

PHP

$httpWxAuthAccessTokenResult = $httpWxAuthAccessToken->wxComponentAccessToken(Json::encode($data));

$response = Yii::$app->wxAuthHttp->createRequest()
    ->setMethod('post')
    ->setHeaders([
        'content-type' => 'application/json; charset=utf-8',
    ])
    ->setUrl('cgi-bin/component/api_component_token')
    ->setContent($data)
    ->send();

16、随后在 HTTP 请求模型中增加耗时记录，以进一步确认请求阶段的实际时间。

PHP

$httpWxAuthAccessTokenResult = $httpWxAuthAccessToken->wxComponentAccessToken($data);

$response = Yii::$app->wxAuthHttp->createRequest()
    ->setMethod('post')
    ->setFormat('json')
    ->setUrl('cgi-bin/component/api_component_token')
    ->setData($data)
    ->send();

17、新的日志显示，多次 HTTP 请求耗时约为 42.26、40.08 和 39.69 毫秒，整体保持在几十毫秒范围。

18、使用 Postman 对微信官方接口进行同样的请求测试，响应耗时约 371 ms；程序侧记录的请求耗时约 40 ms，整体处于正常范围，如图7。

图7

19、查看程序请求日志后，再次确认相关请求通常在 40 毫秒左右完成，如图8。

查看程序请求日志，确认请求耗时约为几十毫秒。
图8

20、因此，5 秒提醒并不像是由程序本身的处理耗时造成。为了继续排除运行模式差异，随后开启生产环境配置并启用程序缓存。

21、再次查看 Nginx 日志，响应时间没有明显变化，upstream_response_time 约为 0.032 秒，说明后端服务处理正常。

}

22、根据 Nginx 日志中的请求信息，在 Postman 中复现同类请求，响应时间约 243 ms，仍明显低于 5 秒，如图9。

23、为了进一步排除业务处理耗时，在程序入口处直接返回 success，但同类提醒仍然出现，如图10。

PHP
<?php
exit('success');
defined('YII_DEBUG') or define('YII_DEBUG', true);
defined('YII_ENV') or define('YII_ENV', 'dev');
 
require __DIR__ . '/../../vendor/autoload.php';
require __DIR__ . '/../../vendor/yiisoft/yii2/Yii.php';
require __DIR__ . '/../../common/config/bootstrap.php';

$config = yii\helpers\ArrayHelper::merge(
    require __DIR__ . '/../../common/config/main.php',

    require __DIR__ . '/../config/main.php',
    require __DIR__ . '/../config/main-local.php'
);
 
(new yii\web\Application($config))->run();

24、随后加入另一个测试环境的通知群进行对比，测试环境没有出现同类提醒，如图11。

25、两个环境使用相同程序，并都基于 Docker 部署，因此开始重点比较两个第三方平台应用的配置差异，并尽量让开发环境与测试环境保持一致。

26、随后对出现提醒的应用重新执行线上发布流程，如图12。

27、第一次提交线上发布时，平台提示接入检测失败，需要重新检查，如图13。

第一次提交线上发布时，平台提示接入检测失败。

28、接着对比两个应用的功能配置，发现出现提醒的应用存在更多权限项，因此先将两边的相关配置调整为一致，如图14。

29、调整后，两边的相关权限配置已经保持一致，如图15。

30、再次执行线上发布接入检测，这次检测成功并提交处理，提交时间为 2020-12-03 20:08，如图16。

31、2020-12-04 16:44:41 收到平台通知，公众号第三方平台【XXX】已完成线上发布，如图17。

公众号第三方平台完成线上发布。
图17

32、完成上述调整后，通知群中没有再出现同类超时提醒。最后一次提醒时间为 2020-12-04 15:54:56。结合前后的对比，可以确认问题与应用的线上发布状态有关，如图18。
