# Gin Web Framework <img align="right" width="159px" src="https://raw.githubusercontent.com/gin-gonic/logo/master/color.png"> [](https://travis-ci.org/gin-gonic/gin) [](https://codecov.io/gh/gin-gonic/gin) [](https://goreportcard.com/report/github.com/gin-gonic/gin) [](https://godoc.org/github.com/gin-gonic/gin) [](https://gitter.im/gin-gonic/gin?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge) [](https://sourcegraph.com/github.com/gin-gonic/gin?badge) [](https://www.codetriage.com/gin-gonic/gin) [](https://github.com/gin-gonic/gin/releases) Gin is a web framework written in Go (Golang). It features a martini-like API with much better performance, up to 40 times faster thanks to [httprouter](https://github.com/julienschmidt/httprouter). If you need performance and good productivity, you will love Gin.  ## Contents - [Installation](#installation) - [Prerequisite](#prerequisite) - [Quick start](#quick-start) - [Benchmarks](#benchmarks) - [Gin v1.stable](#gin-v1-stable) - [Build with jsoniter](#build-with-jsoniter) - [API Examples](#api-examples) - [Using GET,POST,PUT,PATCH,DELETE and OPTIONS](#using-get-post-put-patch-delete-and-options) - [Parameters in path](#parameters-in-path) - [Querystring parameters](#querystring-parameters) - [Multipart/Urlencoded Form](#multiparturlencoded-form) - [Another example: query + post form](#another-example-query--post-form) - [Map as querystring or postform parameters](#map-as-querystring-or-postform-parameters) - [Upload files](#upload-files) - [Grouping routes](#grouping-routes) - [Blank Gin without middleware by default](#blank-gin-without-middleware-by-default) - [Using middleware](#using-middleware) - [How to write log file](#how-to-write-log-file) - [Custom Log Format](#custom-log-format) - [Model binding and validation](#model-binding-and-validation) - [Custom Validators](#custom-validators) - [Only Bind Query String](#only-bind-query-string) - [Bind Query String or Post Data](#bind-query-string-or-post-data) - [Bind Uri](#bind-uri) - [Bind HTML checkboxes](#bind-html-checkboxes) - [Multipart/Urlencoded binding](#multiparturlencoded-binding) - [XML, JSON, YAML and ProtoBuf rendering](#xml-json-yaml-and-protobuf-rendering) - [JSONP rendering](#jsonp) - [Serving static files](#serving-static-files) - [Serving data from reader](#serving-data-from-reader) - [HTML rendering](#html-rendering) - [Multitemplate](#multitemplate) - [Redirects](#redirects) - [Custom Middleware](#custom-middleware) - [Using BasicAuth() middleware](#using-basicauth-middleware) - [Goroutines inside a middleware](#goroutines-inside-a-middleware) - [Custom HTTP configuration](#custom-http-configuration) - [Support Let's Encrypt](#support-lets-encrypt) - [Run multiple service using Gin](#run-multiple-service-using-gin) - [Graceful restart or stop](#graceful-restart-or-stop) - [Build a single binary with templates](#build-a-single-binary-with-templates) - [Bind form-data request with custom struct](#bind-form-data-request-with-custom-struct) - [Try to bind body into different structs](#try-to-bind-body-into-different-structs) - [http2 server push](#http2-server-push) - [Define format for the log of routes](#define-format-for-the-log-of-routes) - [Set and get a cookie](#set-and-get-a-cookie) - [Testing](#testing) - [Users](#users) ## Installation To install Gin package, you need to install Go and set your Go workspace first. 1. Download and install it: ```sh $ go get -u github.com/gin-gonic/gin ``` 2. Import it in your code: ```go import "github.com/gin-gonic/gin" ``` 3. (Optional) Import `net/http`. This is required for example if using constants such as `http.StatusOK`. ```go import "net/http" ``` ### Use a vendor tool like [Govendor](https://github.com/kardianos/govendor) 1. `go get` govendor ```sh $ go get github.com/kardianos/govendor ``` 2. Create your project folder and `cd` inside ```sh $ mkdir -p $GOPATH/src/github.com/myusername/project && cd "$_" ``` 3. Vendor init your project and add gin ```sh $ govendor init $ govendor fetch github.com/gin-gonic/gin@v1.3 ``` 4. Copy a starting template inside your project ```sh $ curl https://raw.githubusercontent.com/gin-gonic/gin/master/examples/basic/main.go > main.go ``` 5. Run your project ```sh $ go run main.go ``` ## Prerequisite Now Gin requires Go 1.6 or later and Go 1.7 will be required soon. ## Quick start ```sh # assume the following codes in example.go file $ cat example.go ``` ```go package main import "github.com/gin-gonic/gin" func main() { r := gin.Default() r.GET("/ping", func(c *gin.Context) { c.JSON(200, gin.H{ "message": "pong", }) }) r.Run() // listen and serve on 0.0.0.0:8080 } ``` ``` # run example.go and visit 0.0.0.0:8080/ping on browser $ go run example.go ``` ## Benchmarks Gin uses a custom version of [HttpRouter](https://github.com/julienschmidt/httprouter) [See all benchmarks](/BENCHMARKS.md) Benchmark name | (1) | (2) | (3) | (4) --------------------------------------------|-----------:|------------:|-----------:|---------: **BenchmarkGin_GithubAll** | **30000** | **48375** | **0** | **0** BenchmarkAce_GithubAll | 10000 | 134059 | 13792 | 167 BenchmarkBear_GithubAll | 5000 | 534445 | 86448 | 943 BenchmarkBeego_GithubAll | 3000 | 592444 | 74705 | 812 BenchmarkBone_GithubAll | 200 | 6957308 | 698784 | 8453 BenchmarkDenco_GithubAll | 10000 | 158819 | 20224 | 167 BenchmarkEcho_GithubAll | 10000 | 154700 | 6496 | 203 BenchmarkGocraftWeb_GithubAll | 3000 | 570806 | 131656 | 1686 BenchmarkGoji_GithubAll | 2000 | 818034 | 56112 | 334 BenchmarkGojiv2_GithubAll | 2000 | 1213973 | 274768 | 3712 BenchmarkGoJsonRest_GithubAll | 2000 | 785796 | 134371 | 2737 BenchmarkGoRestful_GithubAll | 300 | 5238188 | 689672 | 4519 BenchmarkGorillaMux_GithubAll | 100 | 10257726 | 211840 | 2272 BenchmarkHttpRouter_GithubAll | 20000 | 105414 | 13792 | 167 BenchmarkHttpTreeMux_GithubAll | 10000 | 319934 | 65856 | 671 BenchmarkKocha_GithubAll | 10000 | 209442 | 23304 | 843 BenchmarkLARS_GithubAll | 20000 | 62565 | 0 | 0 BenchmarkMacaron_GithubAll | 2000 | 1161270 | 204194 | 2000 BenchmarkMartini_GithubAll | 200 | 9991713 | 226549 | 2325 BenchmarkPat_GithubAll | 200 | 5590793 | 1499568 | 27435 BenchmarkPossum_GithubAll | 10000 | 319768 | 84448 | 609 BenchmarkR2router_GithubAll | 10000 | 305134 | 77328 | 979 BenchmarkRivet_Gi
