Golang http服务端 与 客户端 操作
Golang服务端
package main
import (
"log"
"net/http"
"time"
)
var (
Addr = ":8080"
)
func main() {
// 创建路由器
mux := http.NewServeMux()
// 设置路由规则
mux.HandleFunc("/hello", hello)
// 创建服务器
server := &http.Server{
Addr: Addr,
WriteTimeout: time.Second * 3, //超时时间
Handler: mux, //路由规则
}
// 监听端口并提供服务
log.Println("Starting httpserver at " + Addr)
log.Fatal(server.ListenAndServe())
}
func hello(w http.ResponseWriter, r *http.Request) {
time.Sleep(1 * time.Second)
w.Write([]byte("bye bye ,this is httpServer"))
}
Golang 客户端 也就是http get请求
package main
import (
"fmt"
"io/ioutil"
"net"
"net/http"
"time"
)
func main() {
// 创建连接池
transport := &http.Transport{
DialContext: (&net.Dialer{
Timeout: 30 * time.Second, //连接超时
KeepAlive: 30 * time.Second, //探活时间
}).DialContext,
MaxIdleConns: 100, //最大空闲连接
IdleConnTimeout: 90 * time.Second, //空闲超时时间
TLSHandshakeTimeout: 10 * time.Second, //tls握手超时时间
ExpectContinueTimeout: 1 * time.Second, //100-continue状态码超时时间
}
// 创建客户端
client := &http.Client{
Timeout: time.Second * 30, //请求超时时间
Transport: transport,
}
// 请求数据
resp, err := client.Get("http://127.0.0.1:8080/hello")
if err != nil {
panic(err)
}
defer resp.Body.Close()
// 读取内容
bds, err := ioutil.ReadAll(resp.Body)
if err != nil {
panic(err)
}
fmt.Println(string(bds))
}
