go gin框架：QueryArray接收ids请求参数

package main

import (
  "fmt"
  "net/http"
  "reflect"
  "strings"

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

func main() {
  r := gin.Default()
  r.GET("queryArr", queryArray)
  r.Run()
}

func queryArray(c *gin.Context) {
  ids := c.QueryArray("ids")
  // fmt.Println("第一种方式：", ids.(type)) //i.(type)只能在switch中使用
  fmt.Println("ids", ids)
  fmt.Println("接收到的参数类型：", reflect.TypeOf(ids))
  for k, v := range ids {
    fmt.Printf("%d ==> %v \n", k, reflect.TypeOf(v))
    for i, b := range strings.Split(v, ",") {
      // %c按照字符输出，而不是字符对应的数字值
      // fmt.Printf("%c \n", b)
      fmt.Printf("%d==>%v \n", i, b)
    }
  }

  c.JSON(http.StatusOK, gin.H{
    "ids_": ids,
  })
}
