tp5实现日志记录
1.安装 psr/log
composer require psr/log
它的作用就是提供一套接口,实现正常的日志功能!
我们可以来细细的分析一下,LoggerInterface.php
这是一套日志正常的接口,有层级,有消息,有具体的内容。
LogLevel.php
定义一些错误常量。
AbstractLogger.php实现接口
log(LogLevel::EMERGENCY, $message, $context); } /** * Action must be taken immediately. * * Example: Entire website down, database unavailable, etc. This should * trigger the SMS alerts and wake you up. * * @param string $message * @param array $context * * @return void */ public function alert($message, array $context = array()) { $this->log(LogLevel::ALERT, $message, $context); } /** * Critical conditions. * * Example: Application component unavailable, unexpected exception. * * @param string $message * @param array $context * * @return void */ public function critical($message, array $context = array()) { $this->log(LogLevel::CRITICAL, $message, $context); } /** * Runtime errors that do not require immediate action but should typically * be logged and monitored. * * @param string $message * @param array $context * * @return void */ public function error($message, array $context = array()) { $this->log(LogLevel::ERROR, $message, $context); } /** * Exceptional occurrences that are not errors. * * Example: Use of deprecated APIs, poor use of an API, undesirable things * that are not necessarily wrong. * * @param string $message * @param array $context * * @return void */ public function warning($message, array $context = array()) { $this->log(LogLevel::WARNING, $message, $context); } /** * Normal but significant events. * * @param string $message * @param array $context * * @return void */ public function notice($message, array $context = array()) { $this->log(LogLevel::NOTICE, $message, $context); } /** * Interesting events. * * Example: User logs in, SQL logs. * * @param string $message * @param array $context * * @return void */ public function info($message, array $context = array()) { $this->log(LogLevel::INFO, $message, $context); } /** * Detailed debug information. * * @param string $message * @param array $context * * @return void */ public function debug($message, array $context = array()) { $this->log(LogLevel::DEBUG, $message, $context); }}
Logger.php继承AbstractLogger.php
logger) { }` * blocks. */class Logger extends AbstractLogger{ /** * Logs with an arbitrary level. * * @param mixed $level * @param string $message * @param array $context * * @return void */ public function log($level, $message, array $context = array()) { // noop $logModel = new LogModel(); $logModel->add($level,$message,json_encode($context)); echo $logModel->id; }}
这里面的log方法是我自己写的!!!
我们需要把日志存储到数据库中!!!
这里我设计了一个log表,包含id、level、message、 context、ip、url、create_on等。
我创建了一个LogModel.php
data([ 'level' => $level, 'message' => $message, 'context' => $context, 'ip' => getIp(), 'url' => getUrl(), 'create_on' => date('Y-m-d H:i:s',time()) ]); $this->save(); return $this->id; }}
一切都准备好了,可以在控制器中使用了!
info("有新消息"); } public function _empty() { return "empty"; }}
小结:
composer很好很强大!
这里是接口Interface的典型案例,定义接口,定义抽象类,定义具体类。
有了命名空间,可以很好的引用不同文件夹下的库!
互相使用,能够防止高内聚!即便是耦合也相对比较独立!
有了这个日志小工具,平时接口的一些报错信息就能很好的捕捉了!
只要
use Psr\Log\Logger;
然后
$logger = new Logger();$logger->info("info信息");
使用非常方便!!!
附上获取ip、获取url的方法。
//获取用户真实IPfunction getIp() { if (getenv("HTTP_CLIENT_IP") && strcasecmp(getenv("HTTP_CLIENT_IP"), "unknown")) $ip = getenv("HTTP_CLIENT_IP"); else if (getenv("HTTP_X_FORWARDED_FOR") && strcasecmp(getenv("HTTP_X_FORWARDED_FOR"), "unknown")) $ip = getenv("HTTP_X_FORWARDED_FOR"); else if (getenv("REMOTE_ADDR") && strcasecmp(getenv("REMOTE_ADDR"), "unknown")) $ip = getenv("REMOTE_ADDR"); else if (isset ($_SERVER['REMOTE_ADDR']) && $_SERVER['REMOTE_ADDR'] && strcasecmp($_SERVER['REMOTE_ADDR'], "unknown")) $ip = $_SERVER['REMOTE_ADDR']; else $ip = "unknown"; return ($ip);}// 获取urlfunction getUrl() { return 'http://'.$_SERVER['SERVER_NAME'].':'.$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];}
