要将路径修改为相对路径，您需要使用`http.Dir`函数将文件夹路径转换为`http.FileServer`类型。这样可以指定要提供给用户的静态文件所在的文件夹。以下是对代码的修改：

package main

import (
	"fmt"
	"html/template"
	"log"
	"net/http"
	"strings"
)

func login(w http.ResponseWriter, r *http.Request) {
	fmt.Println("method:", r.Method)
	if r.Method == "GET" {
		t, err := template.ParseFiles("login.html")
		if err != nil {
			http.Error(w, err.Error(), http.StatusInternalServerError)
			return
		}
		if err := t.Execute(w, nil); err != nil {
			http.Error(w, err.Error(), http.StatusInternalServerError)
		}
	} else {
		_ = r.ParseForm()
		fmt.Println("username:", r.Form["username"])
		fmt.Println("password:", r.Form["password"])
		if pwd := r.Form.Get("password"); pwd == "123456" {
			fmt.Fprintf(w, "欢迎登陆,Hello %s!", r.Form.Get("username"))
		} else {
			fmt.Fprintf(w, "密码错误!")
		}
	}
}

func sayHello(w http.ResponseWriter, r *http.Request) {
	_ = r.ParseForm()   //3 解析参数,默认不解析
	fmt.Println(r.Form) //4 输出到服务器端的打印信息
	fmt.Println("Path:", r.URL.Path)
	for k, v := range r.Form {
		fmt.Println("key:", k)
		fmt.Println("value", strings.Join(v, ""))
	}
	fmt.Fprintf(w, "Hello aoho") //5 写入到w的是输出到客户端的内容
}

func main() {
	http.HandleFunc("/", login)
	http.Handle("/static/", http.StripPrefix("/static/", http.FileServer(http.Dir("static"))))
	http.HandleFunc("/sayHello", sayHello)   //1 设置访问的路由
	err := http.ListenAndServe(":8080", nil) //2 设置监听的端口
	if err != nil {
		log.Fatal("ListenSever:", err)
	}
}

这里假设您的静态资源文件夹名为`static`，并且在同一级目录下。使用`http.Handle`和`http.StripPrefix`函数来处理静态文件路由，并指定静态文件夹的相对路径。修改后，您应该能够使用相对路径来访问静态文件。
