package main

import "/gin-gonic/gin"

func main() {
  r := gin.Default()
  r.GET("user/:id/:name", func(c *gin.Context) {
    c.JSON(http.StatusOK, gin.H{
      "rid":   c.Param("id"),
      "rname": c.Param("name"),
    })
  })

  r.GET("/user/:name/:action", func(c *gin.Context) {
    name := c.Param("name")
    action := c.Param("action")
    c.JSON(200, gin.H{
      "name":   name,
      "action": action,
    })
  })

  r.GET("/posts/:name/*action", func(c *gin.Context) {
    name := c.Param("name")
    action := c.Param("action")
    c.JSON(200, gin.H{
      "name":   name,
      "action": action,
    })
  })

  r.Run()
}
