How to add Image in HTML file in Go
问题
首先，我使用Notepad ++创建了一个HTML文件，其中包含以下代码：
<body><table><tr><td>Jill</td><td>Smith</td><td><img src="test.jpg" border=3 height=100 width=300 /></td></tr><tr><td>Eve</td><td>Jackson</td><td>94</td></tr></table></body>
以下是用于此目的的Go语言代码：
// * /func rootHandler(w http.ResponseWriter, r *http.Request) {if r.URL.Path == "/" {homeHandler(w, r)} else {log.Printf("rootHandler: Could not forward request for %s any further.", r.RequestURI)errNotFound(w, r)}}
我希望在浏览器中加载test.png，但它没有起作用。

First of all, I created an HTML file using Notepad ++ with this code:
<body><table><tr><td>Jill</td><td>Smith</td><td><img src="test.jpg" border=3 height=100 width=300 /></td></tr><tr><td>Eve</td><td>Jackson</td><td>94</td></tr></table></body>
Below is the Go language Code for this :-
// * /func rootHandler(w http.ResponseWriter, r *http.Request) {if r.URL.Path == "/" {homeHandler(w, r)} else {log.Printf("rootHandler: Could not forward request for %s any further.", r.RequestURI)errNotFound(w, r)}}
I want test.png should be loaded in browser but its not working.

你可以为处理位于img目录中的函数添加一个处理程序，例如。
以下是一种可能的实现方式：
package mainimport ("fmt""net/http")func RootHandler(w http.ResponseWriter, r *http.Request) {fmt.Fprintf(w, "<h1>Hello</h1><img src='/img/MR.png'/>")}func main() {http.HandleFunc("/", RootHandler) // 主页http.HandleFunc("/img/", func(w http.ResponseWriter, r *http.Request) {http.ServeFile(w, r, r.URL.Path[1:])})http.ListenAndServe(":8080", nil)}
英文:
You can add an handler for dealing with function in an img directory, for example.
Here is one possible way to do it:
package mainimport ("fmt""net/http")func RootHandler(w http.ResponseWriter, r *http.Request) {fmt.Fprintf(w, "<h1>Hello</h1><img src='/img/MR.png'/>")}func main() {http.HandleFunc("/", RootHandler) // homepagehttp.HandleFunc("/img/", func(w http.ResponseWriter, r *http.Request) {http.ServeFile(w, r, r.URL.Path[1:])})http.ListenAndServe(":8080", nil)}
