有默認(rèn)值方式獲取GET請(qǐng)求參數(shù)

package main

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

func main()  {
    app := gin.Default()
    app.Handle("GET", "/", func(context *gin.Context) {
        name := context.DefaultQuery("name", "王二狗")
        context.Writer.Write([]byte(name))
    })
    app.Run()
}

無(wú)默認(rèn)值方式獲取GET請(qǐng)求參數(shù)

package main

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

func main()  {
    app := gin.Default()
    app.Handle("GET", "/", func(context *gin.Context) {
        name := context.Query("name")
        context.Writer.Write([]byte(name))
    })
    app.Run()
}

獲取GET請(qǐng)求參數(shù)的同時(shí)，返回參數(shù)獲取狀態(tài)，狀態(tài)為bool類型

package main

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

func main()  {
    app := gin.Default()
    app.Handle("GET", "/", func(context *gin.Context) {
        name, status := context.GetQuery("name")
        if !status {
            panic("未獲取到name參數(shù)")
        }
        context.Writer.Write([]byte(name))
    })
    app.Run()
}
