Golang web (5)- Send Json

除了send value外gin.context還支援其他泛型

例如底下的json

router.GET("/json", func(ctx *gin.Context) {
  ctx.JSON(200, gin.H{
   "result":    "ok",
   "data":      "Hello, json data.",
   "developer": "jane",
  })
 })

利用context.json回傳json型態資料

完整code如下

package main 
import ( "github.com/gin-gonic/gin") 
// return json data
func main() {
 router := gin.Default()
 router.LoadHTMLGlob("templates/*.html")
 router.GET("/", func(ctx *gin.Context) {
  ctx.HTML(200, "index.html", gin.H{}) })
 router.GET("/data", func(ctx *gin.Context) {
  ctx.HTML(200, "data.html", gin.H{"data": "Hello, template data."}) })
 router.GET("/json", func(ctx *gin.Context) {
  ctx.JSON(200, gin.H{
   "result":    "ok",
   "data":      "Hello, json data.",
   "developer": "jane",
  })
 })
 router.Run(":8000")}
// $ curl -X GET localhost:8000/json
