go:gin output log file method

background

We run the server program and the logs will be printed directly. This article introduces how to output the server logs to the log file

Code

package main

import (
	"io"
	"os"

	"/gin-gonic/gin"
)

func main() {

	// Logging to a file.
	f, _ := ("")
	 = (f)

	// Use the following code if you need to write the logs to file and console at the same time.
	//  = (f, )

	router := ()
	("/ping", func(c *) {
		(200, "pong")
	})

	(":8080")
}

After running the program, the server does not have any information output

Look at the current path.
