How to save log message to file (labstack/echo)
问题
我需要帮助..
我正在使用golang，目前我想将我的日志保存到日志文件中。我使用了echo框架进行日志记录，像这样：
e.Use(middleware.LoggerWithConfig(middleware.LoggerConfig{
Format: "method=${method}, uri=${uri}, status=${status}\n",
}))
有人知道如何将其保存到文件中吗？

LoggerConfig的Output字段是一个io.Writer类型。可以将任何实现了io.Writer接口的对象赋值给Output字段。
f, err := os.OpenFile("logfile", os.O_RDWR|os.O_CREATE|os.O_APPEND, 0666)
if err != nil {
panic(fmt.Sprintf("error opening file: %v", err))
}
defer f.Close()
// 中间件
e.Use(middleware.LoggerWithConfig(middleware.LoggerConfig{
Format: "method=${method}, uri=${uri}, status=${status}\n",
Output: f,
}))
英文:
Output field of LoggerConfig is io.Writer. Set to Output field any io.Writer implementation
f, err := os.OpenFile("logfile", os.O_RDWR|os.O_CREATE|os.O_APPEND, 0666)
if err != nil {
panic(fmt.Sprintf("error opening file: %v", err))
}
defer f.Close()
// Middleware
e.Use(middleware.LoggerWithConfig(middleware.LoggerConfig{
Format: "method=${method}, uri=${uri}, status=${status}\n",
Output: f,
}))
