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()

Functions

func CreateTestContext 

func CreateTestContext(w http.ResponseWriter) (c *Context, r *Engine)

CreateTestContext returns a fresh engine and context for testing purposes

func Dir 

func Dir(root string, listDirectory bool) http.FileSystem

Dir returns a http.FileSystem that can be used by http.FileServer(). It is used internally in router.Static(). if listDirectory == true, then it works the same as http.Dir() otherwise it returns a filesystem that prevents http.FileServer() to list the directory files.

func DisableBindValidation 

func DisableBindValidation()

DisableBindValidation closes the default validator.

func DisableConsoleColor 

func DisableConsoleColor()

DisableConsoleColor disables color output in the console.

func EnableJsonDecoderDisallowUnknownFields 

func EnableJsonDecoderDisallowUnknownFields()

EnableJsonDecoderDisallowUnknownFields sets true for binding.EnableDecoderDisallowUnknownFields to call the DisallowUnknownFields method on the JSON Decoder instance.

func EnableJsonDecoderUseNumber 

func EnableJsonDecoderUseNumber()

EnableJsonDecoderUseNumber sets true for binding.EnableDecoderUseNumber to call the UseNumber method on the JSON Decoder instance.

func ForceConsoleColor 

func ForceConsoleColor()

ForceConsoleColor force color output in the console.

func IsDebugging 

func IsDebugging() bool

IsDebugging returns true if the framework is running in debug mode. Use SetMode(gin.ReleaseMode) to disable debug mode.

func Mode 

func Mode() string

Mode returns current gin mode.

func SetMode 

func SetMode(value string)

SetMode sets gin mode according to input string.

Types

type Accounts 

type Accounts map[string]string

Accounts defines a key/value for user/pass list of authorized logins.

type Context 

type Context struct {
	Request *http.Request
	Writer  ResponseWriter

	Params Params

	// Keys is a key/value pair exclusively for the context of each request.
	Keys map[string]any

	// Errors is a list of errors attached to all the handlers/middlewares who used this context.
	Errors errorMsgs

	// Accepted defines a list of manually accepted formats for content negotiation.
	Accepted []string
	// contains filtered or unexported fields
}

Context is the most important part of gin. It allows us to pass variables between middleware, manage the flow, validate the JSON of a request and render a JSON response for example.

func CreateTestContextOnly 

func CreateTestContextOnly(w http.ResponseWriter, r *Engine) (c *Context)

CreateTestContextOnly returns a fresh context base on the engine for testing purposes

func (*Context) Abort 

func (c *Context) Abort()

Abort prevents pending handlers from being called. Note that this will not stop the current handler. Let's say you have an authorization middleware that validates that the current request is authorized. If the authorization fails (ex: the password does not match), call Abort to ensure the remaining handlers for this request are not called.

func (*Context) AbortWithError 

func (c *Context) AbortWithError(code int, err error) *Error

AbortWithError calls `AbortWithStatus()` and `Error()` internally. This method stops the chain, writes the status code and pushes the specified error to `c.Errors`. See Context.Error() for more details.

func (*Context) AbortWithStatus 

func (c *Context) AbortWithStatus(code int)

AbortWithStatus calls `Abort()` and writes the headers with the specified status code. For example, a failed attempt to authenticate a request could use: context.AbortWithStatus(401).

func (*Context) AbortWithStatusJSON 

func (c *Context) AbortWithStatusJSON(code int, jsonObj any)

AbortWithStatusJSON calls `Abort()` and then `JSON` internally. This method stops the chain, writes the status code and return a JSON body. It also sets the Content-Type as "application/json".

func (*Context) AddParam 

func (c *Context) AddParam(key, value string)

AddParam adds param to context and replaces path param key with given value for e2e testing purposes Example Route: "/user/:id" AddParam("id", 1) Result: "/user/1"

func (*Context) AsciiJSON 

func (c *Context) AsciiJSON(code int, obj any)

AsciiJSON serializes the given struct as JSON into the response body with unicode to ASCII string. It also sets the Content-Type as "application/json".

func (*Context) BaseContext 

func (ctx *Context) BaseContext() context.Context

func (*Context) Bind 

func (c *Context) Bind(obj any) error

Bind checks the Method and Content-Type to select a binding engine automatically, Depending on the "Content-Type" header different bindings are used, for example: 

"application/json" --> JSON binding
"application/xml"  --> XML binding

It parses the request's body as JSON if Content-Type == "application/json" using JSON or XML as a JSON input. It decodes the json payload into the struct specified as a pointer. It writes a 400 error and sets Content-Type header "text/plain" in the response if input is not valid.

BindHeader is a shortcut for c.MustBindWith(obj, binding.Header).

func (*Context) BindJSON

BindTOML is a shortcut for c.MustBindWith(obj, binding.TOML).

func (*Context) BindUri 

func (c *Context) BindUri(obj any) error

func (*Context) BindYAML 

func (c *Context) BindYAML(obj any) error

BindYAML is a shortcut for c.MustBindWith(obj, binding.YAML).

func (*Context) ClientIP 

func (c *Context) ClientIP() string

ClientIP implements one best effort algorithm to return the real client IP. It calls c.RemoteIP() under the hood, to check if the remote IP is a trusted proxy or not. If it is it will then try to parse the headers defined in Engine.RemoteIPHeaders (defaulting to [X-Forwarded-For, X-Real-Ip]). If the headers are not syntactically valid OR the remote IP does not correspond to a trusted proxy, the remote IP (coming from Request.RemoteAddr) is returned.

"application/xml"  --> XML binding

It parses the request's body as JSON if Content-Type == "application/json" using JSON or XML as a JSON input. It decodes the json payload into the struct specified as a pointer. Like c.Bind() but this method does not set the response status code to 400 or abort if input is not valid.
