var DefaultErrorWriter io.Writer = os.Stderr

DefaultErrorWriter is the default io.Writer used by Gin to debug errors.

View Source 
var DefaultWriter io.Writer = os.Stdout

DefaultWriter is the default io.Writer used by 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 ErrBindNonPointerValue = errors.New("can not bind to non-pointer value")

ErrBindNonPointerValue is required bind pointer

type HandlerFunc any

HandlerFunc is a function that can be registered to a route to handle HTTP requests. Like http.HandlerFunc, but support auto binding and auto render.

  4. func(ctx *Context, args S) T { ... }
  5. func(ctx *Context, args S) (T, error) { ... }

Where:

  • S can be struct or map type, S will be auto binding from request body
