golang中的net/http库基本使用详解

import (
	"fmt"
	"log"
	"net/http"
)
var count = 0
func main() {
	http.HandleFunc("/", handler)
	http.HandleFunc("/count", counter)
	log.Fatal(http.ListenAndServe("localhost:8000", nil))
}
func handler(w http.ResponseWriter, r *http.Request) {
	fmt.Fprintf(w, "URL.Path = %q\n", r.URL.Path)
	fmt.Printf("URL.Path = %q\n", r.URL.Path)
}
func counter(w http.ResponseWriter, r *http.Request) {
	count++
	fmt.Fprintf(w, "URL.Path = %q\n", r.URL.Path)
	fmt.Println(count)
}

import (
	"fmt"
	"io/ioutil"
	"net/http"
)
func main() {
	resp, err := http.Get("https://www.baidu.com")
	if err != nil {
		fmt.Println("Error:", err)
		return
	}
	defer resp.Body.Close()
	body, err := ioutil.ReadAll(resp.Body)
	if err != nil {
		fmt.Println("Error:", err)
		return
	}
	fmt.Println(string(body))
}

import (
	"fmt"
	"io/ioutil"
	"net/http"
	"strings"
)
func main() {
	payload := strings.NewReader("data=example")
	resp, err := http.Post("https://www.baidu.com", "application/x-www-form-urlencoded", payload)
	if err != nil {
		fmt.Println("Error:", err)
		return

	defer resp.Body.Close()
	body, err := ioutil.ReadAll(resp.Body)
