快速创建一个httpserver
package main
import (
"net/http"
"fmt"
)
type MyHandler struct{
}
func(*MyHandler) ServeHTTP(write http.ResponseWriter,request *http.Request){
write.Write([]byte("hello,myhandler"));
}
func main(){
handler := new(MyHandler)
server := http.Server{Addr:":8099",Handler:handler}
err := server.ListenAndServe()
if err != nil{
fmt.Println(err)
}
}路由 设置cookie 注销 判断登录
package main
import (
"net/http"
"time"
)
type MyHandler struct {
}
func(*MyHandler) ServeHTTP(writer http.ResponseWriter, request *http.Request){
writer.Write([]byte("hello,myhandler"))
}
func main() {
mymux:=http.NewServeMux()
mymux.HandleFunc("/", func(writer http.ResponseWriter, request *http.Request) {
writer.Write([]byte("index"))
})
mymux.HandleFunc("/login", func(writer http.ResponseWriter, request *http.Request) {
getUserName:= request.URL.Query().Get("username")
if getUserName!=""{
c:=&http.Cookie{Name:"username",Value:getUserName,Path:"/"}
http.SetCookie(writer,c)
}
writer.Write([]byte("这里是登录页面"));
})
mymux.HandleFunc("/unlogin", func(writer http.ResponseWriter, request *http.Request) {
c:=&http.Cookie{Name:"username",Value:"",Path:"/",Expires:time.Now().AddDate(-1,0,0)}
http.SetCookie(writer,c)
writer.Header().Set("Content-type","text/html")
writer.Write([]byte("unlogin...."));
script:=`<script>
setTimeout(()=>{self.location='/'},2000)
</script>`
writer.Write([]byte(script))
})
http.ListenAndServe(":8099",mymux)

自定义路由支持get、post
package main
import (
"net/http"
"gospace/core"
)
type MyHandler struct {
}
func(*MyHandler) ServeHTTP(writer http.ResponseWriter, request *http.Request){
writer.Write([]byte("hello,myhandler"))
}
func main() {
router:=core.DefaultRouter()
router.Get("/", func(writer http.ResponseWriter, request *http.Request) {
writer.Write([]byte("get abc"))
})
router.Post("/", func(writer http.ResponseWriter, request *http.Request) {
writer.Write([]byte("post abc"))
})
http.ListenAndServe(":8099",router)
}main.go
package core
import (
"net/http"
)
type MyRouter struct {
Mapping map[string]map[string]http.HandlerFunc
}
func DefaultRouter() *MyRouter {
return &MyRouter{make(map[string]map[string]http.HandlerFunc)}
}
func(this *MyRouter) Get(path string,f http.HandlerFunc) {
if this.Mapping["GET"]==nil{
this.Mapping["GET"]=make(map[string]http.HandlerFunc)
}
this.Mapping["GET"][path]=f
}
func(this *MyRouter) Post(path string,f http.HandlerFunc) {
if this.Mapping["POST"]==nil{
this.Mapping["POST"]=make(map[string]http.HandlerFunc)
}
this.Mapping["POST"][path]=f
}
func(this *MyRouter) ServeHTTP(writer http.ResponseWriter, request *http.Request){
f:=this.Mapping[request.Method][request.URL.Path]
f(writer,request)
}MyRouter.go
