代码如下：
package main
import (
"github.com/sirupsen/logrus"
"gopkg.in/natefinch/lumberjack.v2"
)
func initLogger(logSetting Utils.LogObj) *logrus.Logger {
logger := logrus.New()
// 使用 lumberjack 提供的 Logger 作为 logrus 的输出
logFile := &lumberjack.Logger{
Filename: "log/cs.log", // 日志文件的位置
MaxSize: logSetting.MaxSize.Value, // 每个日志文件保存的最大尺寸, 单位：MB
MaxBackups: logSetting.MaxBackups.Value, // 日志文件最多保存多少个备份(最近多少个文件)
MaxAge: logSetting.MaxAge.Value, // 文件最多保存多少天
Compress: logSetting.Compress.Value, // 是否压缩/归档旧文件
}
logger.SetReportCaller(logSetting.ReportCaller.Value)
logger.Out = logFile
// 设置日志级别
logger.SetLevel(logrus.InfoLevel)
// 设置日志格式（可选）
formatter := &logrus.TextFormatter{
TimestampFormat: "2006-01-02 15:04:05",
}
if logSetting.TimestampFormat.Value {
logger.SetFormatter(formatter)
}
return logger
}
func main() {
...
//日志
logger := initLogger(settings.Log)
....
go myFunc(logger);
}
func myFunc(logger *logrus.Logger) {
....
logger.Println("wss url exist not token !")
....
}
附：config.json 中 log 节：
"log" :
{
"maxSize" :
{
"value" : 100,
"describe" : "The maximum size of each log file saved, unit: MB"
},
"maxBackups" :
{
"value" : 10,
"describe" : "How many backups of log files can be saved at most (the most recent ones)"
},
"maxAge" :
{
"value" : 28,
"describe" : "How many days can the file be saved for"
},
"compress" :
{
"value" : false,
"describe" : "Whether to compress/archive old files"
},
"reportCaller" :
{
"value" : true,
"describe" : "Whether to display the current line of code"
},
"timestampFormat" :
{
"value" : true,
"describe" : "Whether to display the current time"
}
}
