gin入门

Download and install it:

$ go get github.com/gin-gonic/gin

Import it in your code:

import "github.com/gin-gonic/gin"

(Optional) Import net/http. This is required for example if using constants such as http.StatusOK.

import "net/http"

router := gin.Default()

router.GET("/someGet", getting)

router.POST("/somePost", posting)

// By default it serves on :8080 unless a

// PORT environment variable was defined.

router.Run() // router.Run(":3000") for a hard coded port

Run your project

$ go run main.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")

}
