<pre><code>1.go语言本身的日志系统是很强大的，例如： "log" "github.com/sirupsen/logrus" 但，go语言本身并没有日志轮询机制，(就是将日志定期清理，保存，使之不会不停涨大) 2.此处使介绍了一个 file-rotatelogs 包 "github.com/lestrrat-go/file-rotatelogs" ****它可以和标准的日志结合使用**** 具体参数，程序描述的够清晰了！ 利弊看程序解析！ </code></pre> <pre><code class="lang-go hljs"><span class="token keyword">package</span> main <span class="token keyword">import</span> <span
