### 日志 #### 一、日志文件切割 ```golang package main import ( "fmt" "github.com/nothollyhigh/kiss/log" "io" "os" "time" ) func main() { fileWriter := &log.FileWriter{ RootDir: "./logs/" + time.Now().Format("20060102150405/"), //日志根目录,每次启动新建目录 DirFormat: "200601021504/", //按时间格式分割日志文件子目录,""则不拆分子目录;此处测试按分钟 FileFormat: "20060102150405.log", //按时间格式切割日志文件,此处测试按秒 MaxFileSize: 1024 * 256, //按最大size切割日志文件 EnableBufio: false, //是否启用bufio,重要日志建议不开启 } out := io.MultiWriter(os.Stdout, fileWriter) log.SetOutput(out) log.SetLevel(log.LEVEL_WARN) i := 0 for { i++ log.Debug(fmt.Sprintf("log %d", i)) log.Info(fmt.Sprintf("log %d", i)) log.Warn(fmt.Sprintf("log %d", i)) log.Error(fmt.Sprintf("log %d", i)) } } ``` #### 二、在gin中使用kiss log ```golang package main import ( "fmt" "github.com/gin-gonic/gin" "github.com/nothollyhigh/kiss/log" "os" "time" ) func main() { router := gin.New() router.Use(func(c *gin.Context) { start := time.Now() path := c.Request.URL.Path raw := c.Request.URL.RawQuery c.Next() end := time.Now() latency := end.Sub(start) clientIP := c.ClientIP() method := c.Request.Method statusCode := c.Writer.Status() comment := c.Errors.ByType(gin.ErrorTypePrivate).String() if raw != "" { path = path + "?" + raw } logLevel := log.LEVEL_INFO if latency > time.Second { logLevel = log.LEVEL_WARN } fmt.Fprintf(os.Stdout, log.LogWithFormater(logLevel, log.DefaultLogDepth-1, log.DefaultLogTimeLayout, "| %3d | %13v | %15s | %-7s %s\n%s", statusCode, latency, clientIP, method, path, comment, )) }) //gin.SetMode(gin.ReleaseMode) n := 0 router.GET("/hello", func(c *gin.Context) { n++ if n%2 == 1 { time.Sleep(time.Second) } c.String(200, "hello") }) router.Run(":8080") } ``` #### 三、自定义日志处理 ```golang package main import ( "encoding/json" "fmt" "github.com/nothollyhigh/kiss/log" "runtime" "strings" ) var ( // 按天切割日志文件,日志根目录下不设子目录,不限制单个日志文件大小 fileWriter = &log.FileWriter{ RootDir: "./logs/", //日志根目录 DirFormat: "20060102-1504/", //日志根目录下无子目录 FileFormat: "20060102.log", //日志文件命名规则,按天切割文件 MaxFileSize: 1024 * 1024, //单个日志文件最大size,0则不限制size EnableBufio: false, //是否开启bufio } ) // 实现log.ILogWriter接口 type LogWriter struct{} func (w *LogWriter) WriteLog(l *log.Log) (n int, err error) { _, file, line, ok := runtime.Caller(l.Depth + 1) if !ok { file = "???" line = -1 } else { pos := strings.LastIndex(file, "/") if pos >= 0 { file = file[pos+1:] } } l.File = file l.Line = line data, _ := json.Marshal(l) data = append(data, '\n') n, err = fileWriter.Write(data) fmt.Printf(string(data)) return n, err } func main() { // 设置为nil则默认的日志不处理,如果需要可以同时使用 log.SetOutput(nil) // 设置自定义日志处理接口 log.SetStructOutput(&LogWriter{}) log.SetLevel(log.LEVEL_WARN) for i := 0; i < 10000; i++ { log.Debug("log %d", i) log.Info("log %d", i) log.Warn("log %d", i) log.Error("log %d", i) } } ```
