如何将日志消息保存到文件中(labstack/echo)

import (
    "github.com/labstack/echo/v4"
    "github.com/labstack/echo/v4/middleware"
    "os"
)

e := echo.New()

// 创建日志文件
logFile, err := os.Create("log.txt")
if err != nil {
    // 错误处理
}

// 设置日志中间件
e.Use(middleware.LoggerWithConfig(middleware.LoggerConfig{
    Output: logFile,
}))

e.GET("/", func(c echo.Context) error {
    e.Logger.Info("Hello, World!")
    return c.String(http.StatusOK, "Hello, World!")
})

import (
    "github.com/labstack/echo/v4"
    "github.com/labstack/echo/v4/middleware"
    "os"
    "net/http"
)

func main() {
    e := echo.New()

    // 创建日志文件
    logFile, err := os.Create("log.txt")
    if err != nil {
        // 错误处理
    }

    // 设置日志中间件
    e.Use(middleware.LoggerWithConfig(middleware.LoggerConfig{
        Output: logFile,
    }))

    e.GET("/", func(c echo.Context) error {
        e.Logger.Info("Hello, World!")
        return c.String(http.StatusOK, "Hello, World!")
    })

    e.Start(":8080")
}
