Example analysis: how thinkphp uses middleware to record behavior logs

This article brings you relevant knowledge about PHP. It mainly looks at the problem of using middleware to record behavior logs based on examples, including using log channels to temporarily store behavior logs, using Scheduled tasks regularly write log content to the database, etc. Let’s take a look at it. I hope it will be helpful to everyone.

1. Define middleware

Yes Quickly generate middleware through command line instructions

php think make:middleware Behavior

This instruction will generate a Behavior middleware under the app/middleware directory. The content is as follows:

<?phpdeclare  (strict_types = 1);namespace app\middleware;use think\facade\Log;class Behavior{
    /**
     * 处理请求
     *
     * @param \think\Request $request
     * @param \Closure       $next
     * @return Response
     */
    public function handle($request, \Closure $next)
    {
         //start 加入以下内容
         $admin  =  get_admin_info();   				//当前登录用户的信息,自己实现
         $method = strtolower($request->method());
         $is_ajax = $request->isAjax();
         $route = $request->pathinfo();
         $req = $_REQUEST;
         unset($req['s'],$req['_session']);  
         $req_data = $req ?  json_encode($req) : '';
         $data = [
               'admin_id' => $admin['id'],				//操作人id
               'admin_user' => $admin['user'],			//操作人用户名
               'route' => $route,						//操作的路由地址
               'method' => $method,						//get/post
               'req_tp' => $is_ajax ? 'ajax' : 'normal',
               'req_data' => $req_data,   				 //get/post的数据
               'ip' => getIp(),
               'create_time' => time()
         ];
         //end
         return $next($request);
    }}

2. Use the log channel to temporarily store behavior logs

It is not recommended to write behavior logs to the database in real time to cause unnecessary pressure on the database. We first write the log file cache, Scheduled storage into the database

Tips: Read the official log processing tutorial first https://www.kancloud.cn/manual/thinkphp6_0/1037616Log processing

1. Modification log configuration file

Open config/log.php, add a separate channel for recording behavior logs at the end of 'channels' => []:

 // 其它日志通道配置
 //行为日志
 'behavior'    =>    [
     'path'           => runtime_path().'behavior',  //日志存放目录
     'type'    =>    'File',
     'single' =>     'b',        		//单一文件日志:文件名
     'file_size'   	=> 	1024*1024*10, 	//日志文件大小限制（超出会生成多个文件
     'max_files' => 30,                  //文件最大数量
     'realtime_write'    =>    false,    // 关闭实时写入
 ],

2. Register global middleware

Open app/middleware.php and register a behavior log global middleware

<?php // 全局中间件定义文件return [
    // 全局请求缓存
    // \think\middleware\CheckRequestCache::class,
    // 多语言加载
    // \think\middleware\LoadLangPack::class,
    // Session初始化
    // \think\middleware\SessionInit::class
    // 行为日志
    \app\middleware\Behavior::class,   ];

3. Test whether the log can be successfully generated

Visit any page of this project, for example: http://www.tp6.com/index/index/test?a=1&b=2, and see if the following files can be generated.

Open the file ,The data has been written

{"time":"2022-04-16T21:38:48 08:00","type":"info","msg":"{"admin_id ":888,"admin_user":"fanchen","route":"index\/index\/test","method":"get","req_tp":"normal","req_data":"{\" a\":\"1\",\"b\":\"2\"}","ip":"127.0.0.1","create_time":1650116328}"}

---

3. Use scheduled tasks to regularly write log content to the database

1. Create a new api method, requiring scheduled tasks to be accessible to

 /**
     * 定时任务服务器定时将用户行为日志插入到数据库
     * @return void
     */
    public function sync_behavior_log()
    {
        $path = runtime_path() . 'behavior/b.log';
        $b_file = file_get_contents($path);
        $b_arr = explode(PHP_EOL, $b_file);
        $d = [];
        foreach ($b_arr as $b) {
            $data = json_decode($b, true);
            if (!empty($data['msg'])) {
                $d[] = json_decode($data['msg'], true);
            }
        }
        if ($d) {
            try {
                Db::name('log_behavior')->insertAll($d);     //批量插入数据库
                file_put_contents($path, '');       //清空文件日志
                echo '采集用户行为日志成功' . count($d);
            } catch (DbException $e) {
                echo ($e->getMessage());
            }
        }
    }

2. Create a new behavior log data table log_behavior

SET NAMES utf8mb4;
SET FOREIGN_KEY_CHECKS = 0;

-- ----------------------------
-- Table structure for log_behavior
-- ----------------------------
DROP TABLE IF EXISTS `log_behavior`;
CREATE TABLE `log_behavior`  (
  `id` int(10) UNSIGNED NOT NULL AUTO_INCREMENT COMMENT 'ID',
  `admin_id` int(11) NOT NULL DEFAULT 0 COMMENT '用户id',
  `admin_user` varchar(50) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL DEFAULT '' COMMENT '用户名',
  `route` varchar(50) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '模块名称',
  `method` enum('delete','put','post','get') CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT 'get' COMMENT '请求方式 1get 2post 3put 4delete',
  `req_data` varchar(300) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL DEFAULT '' COMMENT '请求数据',
  `ip` varchar(20) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL DEFAULT '' COMMENT '用户ip',
  `create_time` int(11) NOT NULL DEFAULT 0 COMMENT '创建时间',
  PRIMARY KEY (`id`) USING BTREE,
  INDEX `uid`(`admin_id`) USING BTREE,
  INDEX `admin_user`(`admin_user`) USING BTREE,
  INDEX `route`(`route`) USING BTREE
) ENGINE = InnoDB AUTO_INCREMENT = 3902195 CHARACTER SET = utf8 COLLATE = utf8_general_ci COMMENT = '行为日志' ROW_FORMAT = Compact;

SET FOREIGN_KEY_CHECKS = 1;

3. Create a new scheduled task

Create a new scheduled task and regularly access the sync_behavior_log address in step 1. It is recommended to do so once every 5 minutes.

At this point, when a user accesses, The data table will insert behavior log data in batches every once in a while
