I'm using Gin to make REST API server and Gin shows its output on a console like this: Gin console example
I'd like to make gin's output to a file instead of console.
What I've found is below code from Gin/mode.go
// DefaultWriter is the default io.Writer used the Gin for debug output and
// middleware output like Logger() or Recovery().
// Note that both Logger and Recovery provides custom ways to configure their
// output io.Writer.
// To support coloring in Windows use:
// import "github.com/mattn/go-colorable"
// gin.DefaultWriter = colorable.NewColorableStdout()
var DefaultWriter io.Writer = os.Stdout
var DefaultErrorWriter io.Writer = os.Stderr
Looks like I can change DefaultWriter and DefaultErrorWriter's behavior by setting like
gin.DefaultWriter = something
on my code.
But I have no idea how to write that 'something' code; it must be a function which writes to a file but have no idea how/where to start.
So, my questions are:
Thank you.
You can use os package to create a file.
file, fileErr := os.Create("file")
if fileErr != nil {
fmt.Println(fileErr)
return
}
gin.DefaultWriter = file
This should create a file and start writing to it.
