1. On the third-party platform of WeChat, the error alarm is notified through the WeChat group, and each third-party platform corresponds to the unique alarm group. Scan the code to join to receive the alarm notification. as shown in Figure 1

在微信的第三方平台，错误告警通过微信群来通知，每个第三方平台对应唯一的告警群，扫码加入即可接收告警通知。

2. Frequently receive alarm notifications in the alarm group. Analyze its rules and find that the interval time is 40 minutes. 11:25, 12:15, 12:55, 13:35, 14:15. as shown in Figure 2

在告警群中频繁接收到告警通知。分析其规律，发现其间隔时间为 40 分钟。11:25、12:15、12:55、13:35、14:15。

3. Reference verification bills, website:https://developers.weixin.qq.com/doc/oplatform/Third-party_Platforms/api/component_verify_ticket.html.

4. Check the code implementation

    /**
     * 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. First check the creation time of the generated log file, and find that all generated at 14:35. as shown in Figure 3

6. Decide to print out the server time during the operation of the program one by one, so as to check and analyze which link causes the response time to be too long.

    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. At time: 2020-11-27 14:55:05 Alert once. Look at the creation time of the generated log file again, and find that all generated at 14:55:05. 2020-11-27-14-55-05-1606460105.8643 – 2020-11-27-14-55-05-1606460105.8318 = 3.25 milliseconds. In the end, I decided to observe it a few more times. When you wait for another alarm, check the generation time of the log file. as shown in Figure 4

在时间: 2020-11-27 14:55:05 告警一次。再次查看已经生成的日志文件的创建时间，发现皆在 14:55:05 生成的。间隔 2020-11-27-14-55-05-1606460105.8643 - 2020-11-27-14-55-05-1606460105.8318 = 3.25毫秒。最终决定再多观察几次。等待再一次告警时，查看日志文件的生成时间。

Not more than 5 seconds. However, it was indeed 2 consecutive requests, and a total of 8 log files with timestamps were generated. Maybe it’s because the first request timed out, and then retryed again.

11. It can be roughly determined to know that it should be: obtain the third-party platform Component_Access_Token. Decide to print the time before and after it.

    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. Check the creation time of the log file that has been generated. A fraction of the time interval is significantly longer. Interval 2020-11-30-12-25-06-1606710306.5482 – 2020-11-30-12-25-06-1606710306.2956 = 25.26 milliseconds. 2020-11-30-10-25-07-1606703107.1274 – 2020-11-30-10-25-06-1606703106.7126 = 41.48 milliseconds. 2020-11-30-08-24-50-160695890.2233 – 2020-11-30-08-24-49-160695889.7807 = 44.26 milliseconds. Interval 2020-11-30-06-24-14-160688654.6932 – 2020-11-30-06-24-14-160688654.297 = 39.62 milliseconds. Basically, the interval is 2 hours, and there is a case where 1 response time exceeds 5 seconds.

14. Check the creation time of the log file that has been generated. During 2020-11-30-16-25. Interval 2020-11-30-16-25-30-1606724730.1885 – 2020-11-30-16-25-29-1606724729.7600 = 42.85 milliseconds. Interval Token-2020-11-30-16-25-30-1606724730.1802 – token-2020-11-30-16-25-29-1606724729.7683 = 41.19 milliseconds. Therefore, it can be determined that the cause does not lie in: $HttpWxAuthaAccessToken->wxComponentAccessToken(json::encode($data)).

18. In Postman POST:https://api.weixin.qq.com/cgi-bin/component/api_component_token, response time: 371 ms. The request of the program takes about 40 milliseconds. in line with expectations. as shown in Figure 7

在 Postman 中 POST：https://api.weixin.qq.com/cgi-bin/component/api_component_token ，响应耗费时间：371 ms。而程序的请求耗费时间长达 40 毫秒左右。符合预期。

Figure 7

19. Check the program’s request log. Determined to take about 40 milliseconds. as shown in Figure 8

20. If the response is more than 5 seconds, the bottleneck is not due to the length of the program response time. However, it is decided to start the production environment model of the program, that is, to start the program cache.

21. View the Nginx log. The response time has not changed much. The time returned by upstream_response_time is 0.032 seconds. Indicates that there is no problem with the backend service.

22. Based on the nginx log, and the corresponding log file information, the same request is made in Postman. Response time: 243 ms. Confirm that the response time is less than 5 seconds. as shown in Figure 9

基于 Nginx 日志，与相应的日志文件信息，在 Postman 中发出同样的请求。响应时间：243 ms。确认响应时间是未超过 5 秒的。

Figure 9

23. Decide to respond to the output at the program entrance: SUCCESS. to minimize response time. still keeps alarming. As shown in Figure 10

决定在程序入口处就响应输出：success。以尽可能减少响应时间。仍然持续告警。

24. Decided to scan the code again to join another alarm group (test environment). Not alerted. as shown in Figure 11

Figure 11

25. Since the program is the same, the environment is also based on Docker deployment. It was finally decided to carefully compare the differences between the two third-party platform applications. The development environment application should be configured as much as possible to the test environment application.

26. The application of alarms will be released on the entire network of the existing network. as shown in Figure 12

Figure 12

27. Please confirm whether the submission will be published on the entire network of the existing network? OK. The access detection failed, please try again. as shown in Figure 13

Figure 13

28. Decide to modify the authority management of the alarm application first, so as to be consistent with the unwarming application. There are too many permissions at this stage. Figure 14

Figure 14

29. After the permission management is modified, it is completely the same. as shown in Figure 15

Figure 15

30. The whole network publishes access detection. If the detection is successful, click OK to publish it on the whole network, please wait patiently for review after submitting. OK. Submission time 2020-12-03 20:08. as shown in Figure 16

32. The alarm notification has not been received in the alarm group again. The last alarm notification time is 2020-12-04 15:54:56. From this, it is determined that whether the coverage of the entire network of the existing network is the root cause of the alarm. as shown in Figure 18
