Golang: go get url and form attribute value

go获取urlAnd the form attribute values

一.前言

This section will be used tonet/http包开启web服务,获取request请求, The following router method can integrate globalhandle处理器,In order to make the article simplify,So in the image block of code,只更新handleInside the processor execution logic

package main

import (
	"fmt"
	"net/http"
)

// 处理器
func handle(w http.ResponseWriter, r *http.Request) {
    
	fmt.Fprintln(w, "访问的path路径是: ", r.URL.Path)

}

func main() {
    
	// 路由器
	http.HandleFunc("/", handle)
	// 开启server服务
	http.ListenAndServe(":8081", nil)
}

二.示例

• 获取访问url的path路径

// 处理器
func handle(w http.ResponseWriter, r *http.Request) {
    
	fmt.Fprintln(w, "访问的path路径是: ", r.URL.Path)
}

• 获取访问url的param参数值

// 处理器
func handle(w http.ResponseWriter, r *http.Request) {
    
	fmt.Fprintln(w, "访问的path路径是: ", r.URL.Path)
	fmt.Fprintln(w, "访问的param参数是: ", r.URL.RawQuery)

}

• 获取访问url单个的param参数值

// 处理器
func handle(w http.ResponseWriter, r *http.Request) {
    
	fmt.Fprintln(w, "访问的path路径是: ", r.URL.Path)
	fmt.Fprintln(w, "访问的param参数是: ", r.URL.RawQuery)
	fmt.Fprintln(w, "访问的method是: ", r.Method)
	// 注意FormValue 可以获取get参数还有post参数
	fmt.Fprintln(w, fmt.Sprintf("admin值: %s, age值: %s", r.FormValue("admin"), r.FormValue("age")))
}

• 获取post请求参数值

// 处理器
func handle(w http.ResponseWriter, r *http.Request) {
    
	fmt.Fprintln(w, "访问的path路径是: ", r.URL.Path)
	fmt.Fprintln(w, "访问的param参数是: ", r.URL.RawQuery)
	fmt.Fprintln(w, "访问的method是: ", r.Method)
	// 注意FormValue 可以获取get参数还有post参数
	fmt.Fprintln(w, fmt.Sprintf("admin值: %s, age值: %s", r.FormValue("admin"), r.FormValue("age")))
	// PostFormValue 只会获取post传递过来的参数
	fmt.Fprintln(w, fmt.Sprintf("username值: %s, age值: %s", r.PostFormValue("username"), r.PostFormValue("age")))
}
