2.2 url和路由分组

1. 路由分组

func main() {
    router := gin.Default()
    // Simple group: v1
    v1 := router.Group("/v1")
    {
        v1.POST("/login", loginEndpoint)
        v1.POST("/submit", submitEndpoint)
        v1.POST("/read", readEndpoint)
    }
    // Simple group: v2
    v2 := router.Group("/v2")
    {
        v2.POST("/login", loginEndpoint)
        v2.POST("/submit", submitEndpoint)
        v2.POST("/read", readEndpoint)
    }
    router.Run(":8082")
}

2. 带参数的url

package main
import (
    "github.com/gin-gonic/gin"
    "net/http"
)
func main() {
    r := gin.Default()
    r.GET("/ping", func(c *gin.Context) {
        c.JSON(200, gin.H{
            "message": "pong",
        })
    })
    r.GET("/user/:name/:action/", func(c *gin.Context) {
        name := c.Param("name")
        action := c.Param("action")
        c.String(http.StatusOK, "%s is %s", name, action)
    })
    r.GET("/user/:name/*action", func(c *gin.Context) {
        name := c.Param("name")
        action := c.Param("action")
        c.String(http.StatusOK, "%s is %s", name, action)
    })
    r.Run(":8082") 
}

3. 获取路由分组的参数

package main
import "github.com/gin-gonic/gin"
type Person struct {
    ID string `uri:"id" binding:"required,uuid"`
    Name string `uri:"name" binding:"required"`
}
func main() {
    route := gin.Default()
    route.GET("/:name/:id", func(c *gin.Context) {
        var person Person
        if err := c.ShouldBindUri(&person); err != nil {
            c.JSON(400, gin.H{"msg": err})
            return
        }
        c.JSON(200, gin.H{"name": person.Name, "uuid": person.ID})
    })
    route.Run(":8088")
}
