Gin 使用示例

Gin 日志输出设置

// SetupGinLog 设置 Gin 框架的日志输出
func SetupGinLog() {
	if *LogDir != "" {
		commonLogPath := filepath.Join(*LogDir, "common.log")
		errorLogPath := filepath.Join(*LogDir, "error.log")
		commonFd, err := os.OpenFile(commonLogPath, os.O_APPEND|os.O_CREATE|os.O_WRONLY, 0644)
		if err != nil {
			log.Fatal("failed to open log file")
		}
		errorFd, err := os.OpenFile(errorLogPath, os.O_APPEND|os.O_CREATE|os.O_WRONLY, 0644)
		if err != nil {
			log.Fatal("failed to open log file")
		}
		gin.DefaultWriter = io.MultiWriter(os.Stdout, commonFd)
		gin.DefaultErrorWriter = io.MultiWriter(os.Stderr, errorFd)
	}
}
