## Gin v1. stable
- [x] Zero allocation router.
- [x] Still the fastest http router and framework. From routing to writing.
- [x] Complete suite of unit tests
- [x] Battle tested
- [x] API frozen, new releases will not break your code.
## Start using it
1. Download and install it:
```sh
$ go get gopkg.in/gin-gonic/gin.v1
```
2. Import it in your code:
```go
import "gopkg.in/gin-gonic/gin.v1"
```
3. (Optional) Import `net/http`. This is required for example if using constants such as `http.StatusOK`.
```go
import "net/http"
```
4. (Optional) Use latest changes (note: they may be broken and/or unstable):
   ```sh
$ GIN_PATH=$GOPATH/src/gopkg.in/gin-gonic/gin.v1
$ git -C $GIN_PATH checkout develop
$ git -C $GIN_PATH pull origin develop
   ```
## API Examples
### Using GET, POST, PUT, PATCH, DELETE and OPTIONS
```go
func main() {
// Disable Console Color
// gin.DisableConsoleColor()
// Creates a gin router with default middleware:
// logger and recovery (crash-free) middleware
router := gin.Default()
router.GET("/", func(c *gin.Context) {
c.String(200, "hello world")
router.GET("/someGet", getting)
router.POST("/somePost", posting)
router.PUT("/somePut", putting)
router.DELETE("/someDelete", deleting)
router.PATCH("/somePatch", patching)
router.HEAD("/someHead", head)
router.OPTIONS("/someOptions", options)
// By default it serves on :8080 unless a
// PORT environment variable was defined.
router.Run()
// router.Run(":3000") for a hard coded port
}
```
### Parameters in path
```go
func main() {
router := gin.Default()
// This handler will match /user/john but will not match neither /user/ or /user
router.GET("/user/:name", func(c *gin.Context) {
name := c.Param("name")
c.String(http.StatusOK, "Hello %s", name)
})
router.GET("/ping", func(c *gin.Context) {
c.String(200, "pong")
// However, this one will match /user/john/ and also /user/john/send
// If no other routers match /user/john, it will redirect to /user/john/
router.GET("/user/:name/*action", func(c *gin.Context) {
name := c.Param("name")
action := c.Param("action")
message := name + " is " + action
c.String(http.StatusOK, message)
})
router.POST("/submit", func(c *gin.Context) {
c.String(401, "not authorized")
})
router.PUT("/error", func(c *gin.Context) {
c.String(500, "and error hapenned :(")
router.Run(":8080")
}
```
### Querystring parameters
```go
func main() {
router := gin.Default()
// Query string parameters are parsed using the existing underlying request object.
// The request responds to a url matching: /welcome?firstname=Jane&lastname=Doe
router.GET("/welcome", func(c *gin.Context) {
firstname := c.DefaultQuery("firstname", "Guest")
lastname := c.Query("lastname") // shortcut for c.Request.URL.Query().Get("lastname")
c.String(http.StatusOK, "Hello %s %s", firstname, lastname)
})
router.Run(":8080")
}

##Gin is new, will it be supported?
Yes, Gin is an internal tool of [Manu](https://github.com/manucorporat) and [Javi](https://github.com/javierprovecho) for many of our projects/start-ups. We developed it and we are going to continue using and improve it.
##Roadmap for v1.0
- [ ] Ask our designer for a cool logo
- [ ] Add tons of unit tests
- [ ] Add internal benchmarks suite
- [ ] More powerful validation API
- [ ] Improve documentation
- [ ] Add Swagger support
- [x] Stable API
- [x] Improve logging system
- [x] Improve JSON/XML validation using bindings
- [x] Improve XML support
- [x] Flexible rendering system
- [x] Add more cool middlewares, for example redis caching (this also helps developers to understand the framework).
- [x] Continuous integration
- [x] Performance improments, reduce allocation and garbage collection overhead
- [x] Fix bugs
## Start using it
Obviously, you need to have Git and Go already installed to run Gin.
Run this in your terminal
```
go get github.com/gin-gonic/gin
```
Then import it in your Go code:
```
import "github.com/gin-gonic/gin"
```
##Community

##API Examples
#### Create most basic PING/PONG HTTP endpoint
```go
package main
import "github.com/gin-gonic/gin"
func main() {
r := gin.Default()
r.GET("/ping", func(c *gin.Context) {
c.String(200, "pong")
})
// Listen and server on 0.0.0.0:8080
r.Run(":8080")
}
```
#### Using GET, POST, PUT, PATCH, DELETE and OPTIONS
### Multipart/Urlencoded Form
```go
func main() {
// Creates a gin router + logger and recovery (crash-free) middlewares
r := gin.Default()
router := gin.Default()
r.GET("/someGet", getting)
r.POST("/somePost", posting)
r.PUT("/somePut", putting)
r.DELETE("/someDelete", deleting)
r.PATCH("/somePatch", patching)
r.HEAD("/someHead", head)
r.OPTIONS("/someOptions", options)
router.POST("/form_post", func(c *gin.Context) {
message := c.PostForm("message")
nick := c.DefaultPostForm("nick", "anonymous")
// Listen and server on 0.0.0.0:8080
r.Run(":8080")
c.JSON(200, gin.H{
"status": "posted",
"message": message,
"nick": nick,
})
})
router.Run(":8080")
}
```
#### Parameters in path
### Another example: query + post form
```go
func main() {
r := gin.Default()
// This handler will match /user/john but will not match neither /user/ or /user
r.GET("/user/:name", func(c *gin.Context) {
name := c.Params.ByName("name")
message := "Hello "+name
c.String(200, message)
})
// However, this one will match /user/john/ and also /user/john/send
// If no other routers match /user/john, it will redirect to /user/join/
r.GET("/user/:name/*action", func(c *gin.Context) {
name := c.Params.ByName("name")
action := c.Params.ByName("action")
message := name + " is " + action
c.String(200, message)
})
// Listen and server on 0.0.0.0:8080
r.Run(":8080")
}
```
###Form parameters
POST /post?id=1234&page=1 HTTP/1.1
Content-Type: application/x-www-form-urlencoded
name=manu&message=this_is_great
```
```go
func main() {
r := gin.Default()
// This will respond to urls like search?firstname=Jane&lastname=Doe
r.GET("/search", func(c *gin.Context) {
// You need to call ParseForm() on the request to receive url and form params first
c.Request.ParseForm()
firstname := c.Request.Form.Get("firstname")
lastname := c.Request.Form.get("lastname")
router := gin.Default()
message := "Hello "+ firstname + lastname
c.String(200, message)
router.POST("/post", func(c *gin.Context) {
id := c.Query("id")
page := c.DefaultQuery("page", "0")
name := c.PostForm("name")
message := c.PostForm("message")
fmt.Printf("id: %s; page: %s; name: %s; message: %s", id, page, name, message)
})
r.Run(":8080")
router.Run(":8080")
}
```
#### Grouping routes
```
id: 1234; page: 1; name: manu; message: this_is_great
```
### Upload files
#### Single file
References issue [#774](https://github.com/gin-gonic/gin/issues/774) and detail [example code](examples/upload-file/single).

// single file
file, _ := c.FormFile("file")
log.Println(file.Filename)
c.String(http.StatusOK, fmt.Printf("'%s' uploaded!", file.Filename))
})
router.Run(":8080")
}
```
How to `curl`:

files := form.File["upload[]"]
for _, file := range files {
log.Println(file.Filename)
}
c.String(http.StatusOK, fmt.Printf("%d files uploaded!", len(files)))

#### Model binding and validation
### Model binding and validation
To bind a request body into a type, use model binding. We currently support binding of JSON, XML and standard form values (foo=bar&boo=baz).
Note that you need to set the corresponding binding tag on all fields you want to bind. For example, when binding from JSON, set `json:"fieldname"`.
When using the Bind-method, Gin tries to infer the binder depending on the Content-Type header. If you are sure what you are binding, you can use BindWith.
When using the Bind-method, Gin tries to infer the binder depending on the Content-Type header. If you are sure what you are binding, you can use BindWith.
You can also specify that specific fields are required. If a field is decorated with `binding:"required"` and has a empty value when binding, the current request will fail with an error.
```go
// Binding from JSON
type LoginJSON struct {
User string `json:"user" binding:"required"`
Password string `json:"password" binding:"required"`
}
// Binding from form values
type LoginForm struct {
User string `form:"user" binding:"required"`
Password string `form:"password" binding:"required"`
type Login struct {
User string `form:"user" json:"user" binding:"required"`
Password string `form:"password" json:"password" binding:"required"`
}
func main() {
r := gin.Default()
router := gin.Default()
// Example for binding JSON ({"user": "manu", "password": "123"})
r.POST("/loginJSON", func(c *gin.Context) {
var json LoginJSON
c.Bind(&json) // This will infer what binder to use depending on the content-type header.
if json.User == "manu" && json.Password == "123" {
c.JSON(200, gin.H{"status": "you are logged in"})
} else {
c.JSON(401, gin.H{"status": "unauthorized"})

#### XML and JSON rendering
### Bind Query String
See the [detail information](https://github.com/gin-gonic/gin/issues/742#issuecomment-264681292).
```go
package main
import "log"
import "github.com/gin-gonic/gin"
type Person struct {
Name string `form:"name"`
Address string `form:"address"`
}
func main() {
route := gin.Default()
route.GET("/testing", startPage)
route.Run(":8085")
}
func startPage(c *gin.Context) {
var person Person
// If `GET`, only `Form` binding engine (`query`) used.
// If `POST`, first checks the `content-type` for `JSON` or `XML`, then uses `Form` (`form-data`).
// See more at https://github.com/gin-gonic/gin/blob/develop/binding/binding.go#L45
if c.Bind(&person) == nil {
log.Println(person.Name)
log.Println(person.Address)
}
c.String(200, "Success")
}
```
### Multipart/Urlencoded binding
```go
package main
import (
"gopkg.in/gin-gonic/gin.v1"
)
type LoginForm struct {
User string `form:"user" binding:"required"`
Password string `form:"password" binding:"required"`
}
func main() {
router := gin.Default()
router.POST("/login", func(c *gin.Context) {
// you can bind multipart form with explicit binding declaration:
// c.BindWith(&form, binding.Form)
// or you can simply use autobinding with Bind method:
var form LoginForm
// in this case proper binding will be automatically selected
if c.Bind(&form) == nil {
if form.User == "user" && form.Password == "password" {

} else {
c.JSON(401, gin.H{"status": "unauthorized"})
